Dr Smith: Hello, this is Dr Gordon Smith. Today I've got the great pleasure of interviewing Dr David Oliver about his article on neuropalliative care and neuromuscular disorders, which appears in the December 2025 Continuum issue on neuropalliative care. David, welcome to the Continuum podcast, and please introduce yourself to our audience. Dr Oliver: Thank you. It's a pleasure and a privilege to be here. I'm a retired consultant in palliative medicine in the UK. I worked at the Wisdom Hospice in Rochester for over thirty years, and I'm also an honorary professor at the University of Kent in Canterbury in the UK. I've had a long interest in palliative care in neurological diseases. Hopefully we can talk about a bit later. Dr Smith: I really look forward to learning a little bit more about your path and experiences. But I wonder if, before we get into the meat of neuropalliative care with a focus on neuromuscular, if maybe you can kind of set the stage by just defining palliative care. I mean, my experience is that people think of this in different ways, and a lot of folks think- hear palliative care, and they immediately go to end-of-life care or comfort care. So, what- how should we think about maybe the discipline of palliative care or neuropalliative care? Dr Oliver: I see palliative care as very much responding to people's needs, whether that's physical needs, psychological needs, social or spiritual or existential. So, it can be much earlier in the disease progression. And I think particularly for neurological diseases, early involvement may be very important. Dr Smith: That was actually going to be my first substantive question, really, was when to begin the conversation and what does that look like and how does it evolve over time. You have a really great figure in the article that kind of emphasizes the various stages within a patient's journey that, you know, palliative care can become involved. But I wonder if you could use ALS as a good example and describe what that looks like from when a patient is first diagnosed with ALS through their course? Dr Oliver: I think particularly in ALS at the beginning, soon after diagnosis, someone may have a lot of distress and a lot of questions that they need answering. This is a disease they've not had any contact with before. And they don't understand what's going on, they don't understand the disease. So, there may be a great need to have the opportunity to talk about the disease, what may happen, what is happening, how it's going to affect them and their family. As think time goes on, there may be later they develop swallowing problems, and that will need to be talking about a feeding tube and gastrostomy. And again, there may be a lot of issues for the person and their family. As they deteriorate, they may have respiratory problems and need to have discussion about ventilatory support, either by PAP, noninvasive ventilation, or even tracheostomy. And again, I think that's a big issue that needs wide discussion. And then it may be at the final few months of the disease, where they are deteriorating, that they may have increased needs, and their families may have those needs after the death. And I think often families bereaved from someone with a neurological disease such as ALS need a great deal of support, having many mixed emotions. There may be a feeling of relief that they're not involved in that caring, but then a feeling of guilt that they shouldn't be having those feelings. So, I think that can happen over a period of… what with ALS it may be two, three, four years, but it may be similar changes over time with any patient with a neurological disease. It may be ten or fifteen years with Parkinson's or five to ten years with a progressive supranuclear palsy, but there'll be this similar need to look at palliative care during their disease progression. Dr Smith: So, I'm curious at the time of diagnosis of ALS, how far out in the future do you provide information? So a specific question would be, do you talk about end-of-life management? In my experience, ALS patients are sometimes interested in knowing about that. Or do you really focus on what's in front of you in the next three to six months, for instance? Dr Oliver: I think it's both. Obviously, we need to talk about the next three to six months, but often giving patients the opportunity to talk about what's going to happen in the future, what may happen at the end of life, I think is important. And I think a disease like ALS, if they look it up on the Internet, they may have a lot of very distressing entries there. There's a lot about how distressing dying with ALS is. And actually confront those and discuss those issues early is really important. Dr Smith: So of course, the other thing that comes up immediately with an ALS diagnosis---or, for that matter, with any other neurodegenerative problem---is prognosis. Do you have guidance and how our listeners who are giving a diagnosis of ALS or similar disorder should approach the prognostication discussion? Dr Oliver: It's often very difficult. Certainly in the UK, people may have- be a year into their disease from their first symptoms before they're diagnosed, and I've seen figures, that's similar across the world. So, people may be actually quite way through their disease progression, but I do think we have to remember that the figures show that at five years, 25% of people are still alive, and 5 to 10% are still alive at ten years. We mustn't say you are going to die in the next two or three years, because that may not be so. And I think to have the vagueness but also the opportunity to talk, that we are talking of a deterioration over time and we don't know how that will be for you. I always stress how individual I think ALS is for patients. Dr Smith: One of the other concepts that is familiar with anyone who does ALS and clearly comes through in your article---which is really outstanding, by the way. So, thank you and congratulations for that---is the importance of multidisciplinary teams. Can you talk a little bit about how neuropalliative care sits within a multidisciplinary care model? Dr Oliver: I think the care should be multidisciplinary. Certainly in the UK, we recommended multidisciplinary team care for ALS in particular, from the time of diagnosis. And I think palliative care should be part of that multidisciplinary team. It may be a member of the team who has that palliative care experience or someone with specialist experience. Because I think the important thing is that everyone caring for someone with ALS or other neuromuscular diseases should be providing palliative care to some extent: listening to people, discussing their goals, managing their symptoms. And a specialist may only be needed if those are more complicated or particularly difficult. So, I think it is that the team needs to work together to support people and their families. So, looking at the physical aspects where the physiotherapist or occupational therapist may be very important, the psychologicals are a counsellor or psychologist. The social aspects, most of our patients are part of wider families, and we need to be looking at supporting their carers and within their family as well as the person. And so that may involve social work and other professionals. And the spiritual, the why me, their fears about the future, may involve a spiritual counsellor or a chaplain or, if appropriate, a religious leader appropriate to that- for that person. So, I think it is that wider care provided by the team. Dr Smith: I'm just reflecting on, again, your earlier answers about the Continuum of neuropalliative care. Knowing your patient is super valuable here. So, having come to know someone through their disease course must pay dividends as you get to some of these harder questions that come up later during the disease progression. Dr Oliver: I think that's the very important use of palliative care from early on in the diagnosis. It's much easier to talk about, perhaps, the existential fears of someone while they can still talk openly. To do that through a communication aid can be very difficult. To talk about someone's fear of death through a communication aid is really very, very difficult. The multidisciplinary team, I think, works well if all the members are talking together. So that perhaps the speech therapist has been to see someone and has noticed their breathing is more difficult, comes back and talks to the doctor and the physiotherapist. The social worker notices the speech is more difficult and comes back and speaks to the speech therapist. So, I think that sort of team where people are working very closely together can really optimize the care. And as you said, knowing the person, and for them to know you and to trust you, I think that's important. Those first times that people meet is so important in establishing trust. And if you only meet people when they're very disabled and perhaps not able to communicate very easily, that's really difficult. Dr Smith: I think you're reading my mind, actually, because I was really interested in talking about communication. And you mentioned a few times in your article about voice banking, which is likely to be a new concept for many of our listeners. And I would imagine the spectrum of tools that are becoming available for augmented communication for patients who have ALS or other disorders that impair speech must be impressive. I wonder if you could give us an update on what the state of the art is in terms of approaching communication. Dr Oliver: Well, I think we all remember Stephen Hawking, the professor from Cambridge, who had a very robotic voice which wasn't his. Now people may have their own voice on a communication aid. I think the use of whether it's a mobile phone or iPad, other computer systems, can actually turn what someone types into their own voice. And voice banking is much easier than it used to be. Only a few years ago, someone would have to read for an hour or two hours so the computer could pick up all the different aspects of their voice. Now it's a few minutes. And it has been even- I've known that people have taken their answer phone off a telephone and used that to produce a voice that is very, very near to the person. So that when someone does type out, the voice that comes out will be very similar to their own. I remember one video of someone who'd done this and they called their dog, and the dog just jumped into the air when he suddenly heard his master's voice for the first time in several months. So, I think it's very dramatic and very helpful for the person, who no longer feels a robot, but also for their family that can recognize their father, their husband, their wife's speech again. Dr Smith: Very humanizing, isn't it? Dr Oliver: There is a stigma of having the robotic voice. And if we can remove that stigma and someone can feel more normal, that would be our aim. Dr Smith: As you've alluded to, and for the large majority---really all of our ALS patients, barring something unexpected---we end up in preparing for death and preparing for end of life. I wonder what advice you have in that process, managing fear of death and working with our patients as they approach the end of their journey. Dr Oliver: I think the most important thing is listening and trying to find what their particular concerns are. And as I said earlier, they may have understood from what they've read in books or the Internet that the death from ALS is very distressing. However, I think we can say there are several studies now from various countries where people have looked at what happens at the end of life for people with ALS. Choking to death, being very distressed, are very, very rare if the symptoms are managed effectively beforehand, preparations are made so that perhaps medication can be given quickly if someone does develop some distress so that it doesn't become a distressing crisis. So, I think we can say that distress at the end of life with ALS is unusual, and probably no different to any other disease group. It's important to make sure that people realize that with good symptom control, with good palliative care, there is a very small risk of choking or of great distress at the end of life. Dr Smith: Now, I would imagine many patients have multiple different types of fear of death; one, process, what's the pain and experience going to be like? But there's also being dead, you know, fear of the end of life. And then this gets into comments you made earlier about spirituality and psychology. How do you- what's your experience in handling that? Because that's a harder problem, it seems, to really provide concrete advice about. Dr Oliver: Yeah. And so, I think it's always important to know when someone says they're frightened of the future, to check whether it is the dying process or after death. I've got no answer for what's going to happen afterwards, but I can listen to what someone may have in their past, their concerns, their experience. You know, is their experience of someone dying their memories of someone screaming in pain in an upstairs bedroom while they were a child? Was their grandfather died? Trying to find out what particular things may be really a problem to them and that we can try and address. But others, we can't answer what's going to happen after death. If someone is particularly wanting to look at that, I think that may be involving a spiritual advisor or their local spiritual/religious leader. But often I think it's just listening and understanding where they are. Dr Smith: So, you brought up bereavement earlier and you discussed it in the article. In my experience is that oftentimes the families are very, very impacted by the journey of ALS. And while ALS patients are remarkably resilient, it's a huge burden on family, loved ones, and their community. Can you talk a bit about the role of palliative care in the bereavement process, maybe preparing for bereavement and then after the loss of their loved one? Dr Oliver: Throughout the disease progression, we need to be supporting the carers as much as we are the patient. They are very much involved. As you said, the burden of care may be quite profound and very difficult for them. So, it's listening, supporting them, finding out what their particular concerns are. Are they frightened about what's going to happen at the end of life as well? Are they concerned of how they're going to cope or how the person's going to cope? And then after the death, it's allowing them to talk about what's happened and how they are feeling now, cause I think having had that enormous input in care, then suddenly everything stops. And also, the support systems they've had for perhaps months of the carers coming in, the doctor, the nurse, the physiotherapist, everyone coming in, they all stop coming. So, their whole social system suddenly stops and becomes much reduced. And I'm afraid certainly in the UK if someone is bereaved, they may not have the contact with their friends and family because they're afraid to come and see them. So, they may become quite isolated and reduced in what they can do. So, I think it's allowing them to discuss what has happened. And I think that's as important sometimes for members of the multidisciplinary team, because we as doctors, nurses and the wider team will also have some aspects of bereavement as we face not seeing that person who we've looked after for many years and perhaps in quite an intensive way. So, we need to be looking at how we support ourselves. And I think that's another important role of the multidisciplinary team. I always remember in our team, sometimes I would say, I find this person really difficult to cope with. And the rest of the people around the team would go have a sigh of relief because they felt the same, but they didn't like to say. And once we could talk about it, we could support each other and work out what we could do to help us help the patient in the most effective way. Dr Smith: Well, David, I think that's a great point to end on. I think you've done a really great job of capturing why someone would want to be a palliative care specialist or be involved in palliative care, because one of the themes throughout this conversation is the very significant personal and care impact that you have on patients and families. So, I really appreciate your sharing your wisdom. I really encourage all of our listeners to check out the article, it's really outstanding. I wonder if maybe you might just briefly tell us a little bit about how you got into this space? It's obviously one for which you have a great deal of passion and wisdom. How did you end up where you are? Dr Oliver: I became interested in palliative care as a medical student, and actually I trained as a family doctor, but I went to Saint Christopher's Hospice following that. I had actually had contact with them while I was a medical student, so I worked Saint Christopher's Hospice in South London when Dame Cecily Saunders was still working there. And at that time Christopher's had sixty-two beds, and at least eight of those beds were reserved for people with ALS or other neurological diseases. And I became very involved in one or two patients and their care. And Dame Sicily Saunders asked me to write something on ALS for their bookshelf that they had on the education area. So, I wrote, I think, four drafts. I went from sort of C minus to just about passable on the fourth draft. And that became my big interest in particularly ALS, and as time went on, in other neurological diseases. When I went to the Wisdom Hospice as a consultant, I was very keen to carry on looking after people with ALS, and we involved ourselves with other neurological patients. That's how I got started. Having that interest, listening to patients, documenting what we did became important as a way of showing how palliative care could have a big role in neurological disease. And over the years, I've been pressing again and again for the early involvement of palliative care in neurological diseases. And I think that is so important so that there can be a proper holistic assessment of people, that they can build up the trust in their carers and in the multidisciplinary team so that they can live as positively as possible. And as a result of that, that their death will be without distress and with their family with them. Dr Smith: Well, David, you've convinced and inspired me, and I'm confident you have our listeners as well. Thank you so much for a really informative, enjoyable, inspiring conversation.

Dr Nevel: Hello, this is Dr Kait Nevel. Today I'm interviewing Dr Claire Creutzfeldt about her article on neuropalliative care in severe acute brain injury and stroke, which appears in the December 2025 Continuum issue on neuropalliative care. Claire, welcome to the podcast, and please introduce yourself to the audience. Dr Creutzfeldt: Thanks, thanks for having me. Yeah, I'm an associate professor of neurology at the University of Washington. I'm a stroke neurologist and palliative care researcher and really have focused my career on how we can best integrate palliative care principles into the care of patients with severe stroke and other neurocritical illness. Dr Nevel: Wonderful. Well, I'm looking forward to talking to you today about your excellent article that I really enjoyed reading. To get us started, can you tell us what you feel is the most important takeaway from your article for the practicing neurologist? Dr Creutzfeldt: Yeah. You know, I think one is always a little biased by what one is working on currently. And I think what I'm most excited about or feel more strongly about is this idea that stroke and severe acute brain injury are not an event, but really a chronic illness that people are left with usually for the rest of their lives, that change their life radically. And I think that education, research funding, also the clinical setting, current healthcare models aren't set up for that. And this idea that severe acute brain injury, you know, should be viewed as a lifelong condition that requires support across all ranges of goals of care. So curative, restorative, palliative and end-of-life care. Dr Nevel: Yeah, I love that part of your article, how you really highlighted that concept. And I think obviously that's something that we see in neurology and learn, especially as we transition out of our residency stages. But I think especially for the trainees listening, can sometimes be hospital inpatient-heavy, if you will, that kind of you can lose sight of that, that these acute strokes, severe acute brain injury, it turns into a chronic illness or condition that patients are dealing with lifelong. Dr Creutzfeldt: Often what we do in a very acute setting is like, is really cool and sexy and like, we can cure people from their stroke if they come, you know, at the right time with the right kind of stroke to the right hospital. And often the symptoms that people come in with much later on are harder to treat and address, partly because the focus in education, clinical and research just hasn't been as much on that time. Dr Nevel: Yeah, absolutely. So, can you talk to us about this concept of total pain? What does it mean, and how do we incorporate this concept into the way that we view our approach, our patient care? Dr Creutzfeldt: Total pain is a very old word, but it's sort of coming back into fashion in the palliative care world because it really describes all those sources of suffering or sources of distress, like, beyond what we sort of really think of as sort of the physical symptoms in recovery of stroke. As many of you know, palliative care often thinks in this multidimensional way of the physical distress, physical pain, but also psychological, emotional, social and spiritual, existential. And both- we sort of created sort of a figure that incorporates all of them and also includes both patients and their family members. They share some of these sources of distress, but they also have distinct ones that need to be addressed. And at the core of that total pain is what we need to provide, is sort of optimal communication and goals-of-care prognosis. Dr Nevel: Yeah, I'm thinking about all of those aspects and not just focusing on one. How does the disease trajectory of severe acute brain injury and stroke play a role in the palliative care approach? And how should we kind of going back to that original point of this idea of severe acute brain injury being an acute event and then oftentimes turning into kind of a chronic condition? How does that play a role in how we address palliative care with our patients, or kind of the stages of palliative care with our patients? Dr Creutzfeldt: Yeah, I think several things, especially for neurologists, is the more traditional palliative care illnesses, like cancer or congestive heart failure, illnesses where people are diagnosed when they're still functioning at a relatively high level and tend to have time to consider their prognosis and their goals of care in the end of life wishes and to meet with palliative care and to consider their personhood. Who am I? What's most important for me? And stroke, people with stroke, they not only present at their worst, they meet us at their worst, at a time when the patient themselves usually can't speak for themselves, when their personhood has been stripped from them. And then as providers, we, you know, we often really just get that one opportunity to get the conversation right and to guide people towards, you know, what we would call optimal and goal-concordant care. So, the challenges are many. I do think that the burden of these early conversations is on neurologists and really requires the neurologists to show compassion, to learn communication skills, think really hard about how you want to communicate prognosis and goals of care early on, because it's going to color people's experiences and decisions longitudinally. You asked about, sort of, this trajectory. And I do think it's important to think about, you know, what really happens even after the thrombectomy or even after we discharge people, especially from the ICU. Because for us, often after sort of day five or six, you know, we're sort of done. We're thinking about secondary stroke prevention. And, you know, how do I get the patient to rehab or out of the hospital? For the patients and families, this is when it really all just starts. You know, this is when they- when they're first memories are usually, you know, they hardly remember that acute setting. And so, when they are medically stable, we're done with the acute blood pressure treatment where we've removed the Foley, we've made a decision about nutrition. For us that tends to be a time where we let go a little; for patients and families that tends to actually be the time when they have to think about how am I going to live with this and what are the next several months or years going to look like? And so being there for them is important. Dr Nevel: That's such a, I think, important point, that when we have our plan in place, we know medically what the plan is for that patient and we're starting to step back, think about rehab or discharge. That's when oftentimes more quote-unquote "reality" steps in for patients and families about what their future is going to look like. Dr Creutzfeldt: And medical stability is not even close to neurological stability. And so, they are still in the middle of real prognostic uncertainty, and often waxing and waning symptoms or new symptoms coming up for them. Like pain, you know, post thalamic pain syndrome, just as an example, tends to be something that doesn't develop until later. Dr Nevel: Right, right. Absolutely. And since you touched on this concept of prognostic uncertainty, and, you know, that's something that's so challenging in severe acute brain injury, especially the early days when you talk about this, you know, that things tend to become a little bit more certain as more time passes. But these are really hard conversations because a lot of times feel like big decisions that need to be made early on, you know? Dr Creutzfeldt: Huge! Dr Nevel: Sometimes things like trach and PEG and things like that. How do you approach that conversation? I know you talk about that a little bit in your article. You touch on that, some of the, kind of, strategies or concepts that we use in palliative care to approach this prognostic uncertainty with patients. Dr Creutzfeldt: Yeah, I think the challenge is to balance this acknowledging uncertainty with still being able to guide the families and allow them to trust you. So, there are a few things that I have said in the past, and I have taught in the past, and I don't use anymore. They include sentences like I don't have a crystal ball, for example. Nobody was asking you for one. The other one that I want us to avoid, I think, is the sentence we are terrible at prognosticating. Because what I have seen is that that sentence carries on for families. And families at nine months are still saying, well, you guys are terrible at prognosticating. That's what you told me. First of all, it's all relative, and relative to non-neural providers---even at this time using Google and AI, we're actually quite good at prognosticating. It's just that a wide range early on. So that's how I would change that sentence is, early on after stroke, the range of possible outcomes is still very wide. And so, you've communicated uncertainty without saying I have no idea what I'm doing, which is not true. That is in order to help families be able to trust you and also to trust the person who comes after you, because we all know that a week or two after admission, we do know a lot more. And if we told them on day one that we're terrible at prognosticating, it's hard to sort of build that trust again later. You also asked about, you know, communication strategies. And I think it's this range of possible outcomes that I think is a good guideline for us to work on. And that range, sort of like a confidence interval, is still very wide early on. And as we collect more information over time, both about the clinical scenario that is evolving in front of us and about the patient who we are learning more about over time, this confidence interval becomes smaller. And that's where this idea of the best case/worst case scenario sort of conversation, for example, comes from: that range of possible outcomes. Dr Nevel: So, what to you is most challenging about palliative care for patients with severe acute brain injury and stroke? Dr Creutzfeldt: I think the biggest challenge in stroke care is balancing restorative and curative care with palliative and end-of-life. And that is especially early on when sort of everything is possible, when patients and families want to hear the good news and, I think, are also quite willing to hear the bad news, and probably should. So, I think that that communication is hard when, you know, really we want to provide goal-concordant care. We want to make sure that people get that care that is most important to them and can meet the outcomes that are most important to them. Dr Nevel: Yeah, agree. What is most rewarding? Dr Creutzfeldt: I think these patients and families have enormous needs and are extremely grateful if they can find someone that they can trust and who can guide them and who will stick with them. And when I say someone, I think that can be a team. That always depends on how we communicate. In the ideal world, it would be the same person following someone over time, the patient and the family over time. But in our current healthcare system, we're usually moving on from one place to another and being able to communicate with the people that come after you. Telling the family that you're a team and supporting them through that, I think, is really important. Dr Nevel: Yeah. And like you touched upon, patients and families, I think oftentimes they're looking for, you mentioned, you know, the sharing and communication and they're looking for information. Dr Creutzfeldt: You know, what's really rewarding is working with a team. And health care has really excelled at that. And I think we have a lot done from them is that it's not always the MD that family needs. And we have a lot of people at our side, and I think we need more of them. Chaplains, social workers; psychologists, actually, I think; and nurses or- in an ideal world, would really work together to support these multidisciplinary, multidimensional symptoms. Dr Nevel: Yeah. I think it benefits both the patient and the care team, too. Dr Creutzfeldt: Absolutely! Dr Nevel: It's helpful to be part of a team. You know, there's camaraderie in that and, like, a shared goal, and I think the thought is rewarding, too. Dr Creutzfeldt: If we really try and think about severe stroke as a chronic illness or severe acute brain injury as a chronic illness not unlike cancer, then if you think about the systems that have been built for cancer where an entire team of providers follows the patient and their family member over time, I think we need that, too. Dr Nevel: Yeah, I agree. That point, every member of the team has overlapping things, but has a slightly individual role to a degree too, which is also helpful to the patient and the family. You talked about this a little bit in your article, and I want to hear more from you about what we know about healthcare disparities in this area of medicine and in providing palliative care for patients with severe acute brain injury and stroke. Dr Creutzfeldt: Yeah, I think actually a lot of the huge decisions that we make, especially early on, are highly variable. And can identify people by various things, whether it's their race or ethnicity or sex or age, or even where they live in the United States. But decisions tend to be made differently. And so, just as an example, we know that I think people who identify as black, for sure, are less likely to receive the acute, often life-saving interventions like TNK or thrombectomy and more likely to undergo longer-term, life-prolonging treatment like PEG and trach. That seems true, after adjusting for clinical severity and things like that. And so disparities like that may be based on cultural preferences or well-informed decisions, and then we can support them. But of course, unfortunately there's a clear idea when we see, often, unexplained variability that a lot is due to uninformed decisions and poor communication and possibly racism in certain parts. And that is, of course, something that has to be addressed. Dr Nevel: Yeah, absolutely. What are future areas of research in this area? I know you do a lot of research in this area and I'd love to hear about some of it and what you think is exciting or kind of new and going to change the way we think about things, perhaps. Dr Creutzfeldt: I think every aspect of stroke continues to be exciting and just, you know, our focus of today and my research is on palliative care. I mean, obviously, the things we can do in rehab these days have to be embraced, and the acute stuff. But I think this longitudinal support, an ideally longitudinal multidisciplinary support for patients and families, requires more research. I think it will help us with prognosis. It will help us with communicating things early on and learning more about sort of multidimensional symptoms of these patients over time. That requires more research. And then, how can we change the healthcare system---in a sustainable way, obviously---to maximize quality of life for the survivors and their families? Dr Nevel: Going back to that total pain again, making sure that we're incorporating that longitudinally. Dr Creutzfeldt: I think there are currently 94 million people worldwide living with the aftermath of a stroke. I joined a stroke survivor support group recently. People are supporting each other that have that had their stroke, like, 14 years ago and are still in that just to show that this is not one and done. People are still struggling with symptoms afterwards and want support. Dr Nevel: Before we close out, is there anything else that you'd like to add? Dr Creutzfeldt: Your questions have all been great, and I think one observation is that we've talked a lot about, sort of, new ideas of the need for longitudinal care for patients after severe stroke. There's still a ton for all of us to do to optimize the care we provide in the very acute setting, to optimize the way we communicate in the very acute setting. To make sure we are, for example, providing the same message as our team members and providing truly compassionate goal-concordant care from the time they hit the emergency room throughout. Including time-limited trials, for example. Dr Nevel: Well, thank you so much for chatting with me today about your article on this really important topic. Again, today I've been interviewing Dr Claire Creutzfeldt about her article on neuropalliative care in severe acute brain injury and stroke, which appears in the December 2025 Continuum issue on neuropalliative care. Be sure to check out Continuum Audio episodes from this and other issues. And as always, to our listeners, please check out the article. It's great, highly recommend. And thank you to our listeners for joining us today. And thank you so much, Claire, for sharing your expertise with us today. Dr Creutzfeldt: Thanks for having me.

In the hospital setting, neurologists may be responsible for managing common end-of-life symptoms. Comprehensive end-of-life care integrates knowledge of the biomedical aspects of disease with patients' values and preferences for care; psychosocial, cultural, and spiritual needs; and support for patients and their families. In this episode, Teshamae Monteith, MD, FAAN, speaks with Claudia Z. Chou, MD, author of the article "End-of-Life Care and Hospice" in the Continuum® December 2025 Neuropalliative Care issue. Dr. Monteith is the associate editor of Continuum® Audio and an associate professor of clinical neurology at the University of Miami Miller School of Medicine in Miami, Florida. Dr. Knox is an assistant professor of neurology and a consultant in the Division of Community Internal Medicine, Geriatrics and Palliative Care at Mayo Clinic in Rochester, Minnesota.

Dr Monteith: This is Dr Teshamae Monteith. Today I'm interviewing Dr Claudia Chou about her article on end-of-life care and hospice, which is found in the December 2025 Continuum issue on neuropalliative care. Welcome to our podcast. How are you? Dr Chou: I'm doing well. Thank you for having me. This is really exciting to be here. Dr Monteith: Absolutely. So, why don't you introduce yourself to our audience? Dr Chou: Sure. My name is Claudia Chou. I am a full time hospice and palliative medicine physician at Mayo Clinic in Rochester. I'm trained in neurology, movement disorders, and hospice and palliative medicine. I'm also passionate about education, and I'm the program director for the Hospice and Palliative Medicine fellowship here. Dr Monteith: Cool. So just learning about your training, I kind of have an idea of how you got into this work, but why don't you tell me what inspired you to get into this area? Dr Chou: It was chance, actually. And really just good luck, being in the right place at the right time. I was in my residency and felt like I was missing something in my training. I was seeing these patients who were suffering strokes and had acute decline in functional status. We were seeing patients with new diagnosis of glioblastoma and knowing what that future looked like for them. And while I went into neurology because of a love of neuroscience, localizing the lesion, all of those things that we all love about neurology, I still felt like I didn't have the skill set to serve patients where they perhaps needed me the most in those difficult times where they were dealing with serious illness and functional decline. And so, the serendipitous thing was that I saw a grand rounds presentation by someone who works in neurology and palliative care for people with Parkinson's disease. And truly, it's not an exaggeration to say that by the end of that lecture, I said, I need to do palliative care, I need to rotate in this, I need to learn more. I think this is what I've been missing. And I had plans to practice both movement disorders neurology and palliative care, but I finished training in 2020… and that was not a long time ago. We can think of all the things that were going on, all the different global forces that were influencing our day-to-day decisions. And the way things worked out, staying in palliative care was really what my family and I needed. Dr Monteith: Wow, so that's really interesting. Must have been a great lecturer. Dr Chou: Yes, like one of the best.  Dr Monteith: So why don't you tell me about the objectives of your article? Dr Chou: The objectives may be to fill in some of the gaps in knowledge that may be present for the general neurologist. We learn so much in neurology training, so much about how to diagnose and treat diseases, and I think I would argue that this really is part and parcel of all we should be doing. We are the experts in these diseases, and just because we're shifting to end-of-life or transitioning to a different type of care doesn't mean that we back out of someone's care entirely or transition over to a hospice or palliative care expert. It is part of our job to be there and guide patients and their care partners through this next phase. You know, I'm not saying we all need to be hospice and palliative care experts, but we need to be able to take those first steps with patients and their care partners. And so, I think objectives are really to focus in on, what are those core pieces of knowledge for end-of-life care and understanding hospice so we can take those first steps with patients and their care partners? Dr Monteith: So, why don't you give us some of those essential points in your article? Dr Chou: Yeah. In one section of the article, I talk about common symptoms that someone might experience at the end of life and how we might manage those. These days, a lot of hospitals have order sets that talk us through those symptoms. We can check things off of a drop-down menu. And yet I think there's a little bit more nuance to that. There may be situations in which we would choose one medication over another. There may be medications that we've never really thought of in terms of symptom management before. Something that I learned in my hospice and palliative medicine fellowship was that haloperidol can be helpful for nausea. I know that's usually not one of our go-tos in neurology for any number of reasons. So, I think that extra knowledge can take us pretty far when we're managing end of life symptoms, particularly in the hospital setting. And then I think the other component is the hospice component. A lot of us may have not had experience talking about hospice, talking about what hospice can provide, and again, knowing how to take those first steps with patients. We may be referring to social work or palliative medicine to start those conversations. But again, I think this is something that's definitely learnable and something that should be part of our skill set in neurology. Dr Monteith: Great. And so, when you speak about symptom management and being more comfortable with the tools that we have, how can we be more efficient and more effective at that? Dr Chou: Think about what the common symptoms are at end of life. We may know this kind of intuitively, but what we commonly see are things like pain, nausea, dyspnea, anxiety, delirium or agitation. And so, I think having a little bit of a checklist in mind can be helpful. You know, how can I systematically think through a differential, almost, for why my patient might be uncomfortable? Why they might be restless? Have I thought through these different symptoms? Can I try a medication from my tool kit? See if that works, and if it does, we can continue on. If not, what's the next thing that I can pivot to? So, I think these are common skills for a little bit of a differential diagnosis, if you will, and how to work through these problems just with the end-of-life lens on it. Dr Monteith: So, are there any, like, validated tools or checklists that are freely available? Dr Chou: I don't think there's been anything particularly validated for end-of-life care in neurologic disease. And so, a lot of our treatments and our approaches are empiric, but I don't think there's been anything validated, per se. Dr Monteith: Great. So, why don't we talk a little bit about the approach to discussions on hospice? We all, as you kind of alluded to, want to be effective neurologists, care for our patients, but we sometimes deal with very debilitating diseases. And so, when we think that or suspect that our patient is kind of terminally ill, how do we approach that to our patients? Of course, our patients come from different backgrounds, different experiences. So, what is your approach? Dr Chou: So, when we talk about hospice and when a patient may be appropriate for hospice, we have to acknowledge that we think that they may be in the last six months of their disease. We as the neurologist are the experts in their disease and the best ones to weigh in on that prognosis. The patient and their care partners then have to accept that the type of care that hospice provides is what makes sense for them. Hospice focuses on comfort and treating a patient's comfort as the primary goal. Hospice is not as interested in treating cancer, say, to prolong life. Hospice is not as interested in life-prolonging measures and treatments that are not focused at comfort and quality of life. And so, when we have that alignment between our understanding of a patient's disease and their prognosis and the patient care partner's goal is to focus on comfort and quality of life above all else, that's when we have a patient who might be appropriate for hospice and ready to hear more about what that actually entails. Dr Monteith: And what are some, maybe, myths that neurologist healthcare professionals may have about hospice that you really want us to kind of have some clarity on? Dr Chou: That's a great question. What we often tell patients is that hospice's goal is to help patients live as well as possible in the time that they have left. Again, our primary objective is not life prolongation, but quality of life. Hospice's goal is also not to speed up or slow down the natural dying process. Sometimes we do get questions about that: can't you make this go faster or we're ready for the end. But really, we are there to help patients along the natural journey that their body is taking them on. And I think hospice care can actually be complex. In the inpatient setting, in particular in neurology, we may be seeing patients who have suffered large strokes and have perhaps only days to a few weeks of life left. But in the outpatient setting and in the home hospice setting, patients can be on hospice for many months, and so they will have new care needs, new urinary tract infections, sometimes new rashes, the need to change their insulin regimens around to avoid extremes of hyperglycemia or hypoglycemia. So, there is a lot of complexity in that care and a lot that can be wrapped up under that quality-of-life and comfort umbrella. Dr Monteith: And to get someone to hospice requires a bit of prognostication, right? Six months of prediction in terms of a terminal illness. I know there's some nuances to that. So how can you make us feel more comfortable about making the recommendations for hospice? Dr Chou: I think this is a big challenge in the field. We're normally guided by Medicare guidelines that say when a patient might be hospice-appropriate. And so, for a neurologic disease, this really only encompasses four conditions: ALS, stroke, coma, and Alzheimer's dementia. And we can think of all the other diseases that are not encompassed in those four. And so, I think we say that we paint the picture of what it means to have a prognosis of six months or less. So, from the neurologic side, that can be, what do you know about this disease and what end-stage might look like? What is the pattern of the patient's functional decline? What are they needing more help with? Are there other factors at play such as heart failure or COPD that may in and of themselves not be a qualifying diagnosis for hospice, but when it's taken together in the whole clinical picture, you have a patient who's very ill and one that you're worried may die in the next six months or less? Dr Monteith: Then you also had some nice charts on kind of disease-specific guidelines. Can you take us a little bit through that? Dr Chou: The article does contain tables about specific criteria that may qualify someone for hospice with these neurologic conditions. And they are pretty dense. I know they're a checklist of a lot of different things. And so, how we practice is by trying to refer patients to hospice based on those guidelines as much as possible and then using our own clinical judgment as well, what we have seen through taking care of patients through the years. So, again, really going back to that decline. What is making you feel uncomfortable about this patient's prognosis? What is making you feel like, gosh, this patient could be well supported by hospice, and they could have six months or less? So, all of that should go into your decision as well. And all of that should go into your discussion with the patient and their care partners. Dr Monteith: Yeah. And reading your article, what stood out was all the services that patients can receive under hospice. So, I think sometimes people think, okay, this is terminal illness, let's get to hospice for whatever reasons, but not necessarily all the lists and lists and lists of benefits of hospice. So, I don't know that everyone's aware of all those benefits. So, can you talk to us a little bit about that? Dr Chou: Yeah, I like that you brought that up because that's also something that I often say to patients and their care partners when we're talking about hospice. When the time is right for a patient to enroll in hospice, they should not feel like they're giving anything up. There should be no more clinical trial that they're hoping to chase down, and so they should just feel like they're gaining all of those good supports: care that comes to their home, a team that knows them well, someone that's available twenty-four hours a day by phone and can actually even come into the home setting if needed to help with symptom management. Hospice comes as well with the psychosocial supports for just coping with what dying looks like. We know that's not easy to be thinking about dying for oneself, or for a family member or care partner to be losing their loved one. So, all of those supports are built into hospice. I did want to make a distinction, too, that hospice does not provide custodial care, which I explain to patients as care of the body, those daily needs for bathing, dressing, eating, etc. Sometimes patients are interested in hospice because they're needing more help at home, and I have to tell them that unfortunately, our healthcare system is not built for that. And if that's the sole reason that someone is interested in hospice, we have to think about a different approach, because that is not part of the hospice benefit.  Dr Monteith: Thank you for that. And then I learned about concurrent care. So why don't you tell us a little bit about that? That's a little bit of a nuance, right? Dr Chou: Yeah, that is a little bit of a nuance. And so, typically when patients are enrolling in hospice, they are transitioning from care the way that it's normally conducted in our healthcare system. So, outpatient visits to all of the specialists and to their primary care providers, the chance to go to the ER or the ICU for higher levels of care. And yet there are a subset of patients who can still have all of those cares alongside hospice care. That really applies to two specific populations: veterans who are receiving care through the Veterans Administration, and then younger patients, so twenty six years old and less, can receive that care through, essentially, a pediatric carve out. Dr Monteith: Great. Well, I mean, you gave so much information in your article, so our listeners are going to have to read it. I don't want you to spill everything, but if you can just kind of give me a sense what you want a neurologist to take away from your article, I think that would be helpful. Dr Chou: I think what I want neurologist to take away is that, again, this is something that is part of what we do as neurologists. This is part of our skill set, and this is part of what it means to take good care of patients. I think what we do in this transition period from kind of usual cares, diagnosis, full treatment to end of life, really can have impact on patients and their care partners. It's not uncommon for me to hear from family members who have had another loved one go through hospice about how that experience was positive or negative. And so, we can think about the influence for years to come, even, because of how well we can handle these transitions. That really can be more than the patient in front of us in their journey. That is really important, but it can also have wide-reaching implications beyond that. Dr Monteith: Excellent. And I know we were talking earlier a little bit about your excitement with the field and where it's going. So why don't you share some of that excitement? Dr Chou: Yeah. And so, I think there is a lot still to come in the field of neuropalliative care, particularly from an evidence base. I know we talked a lot about the soft skills, about presence and communication, but we are clinicians at heart, and we need to practice from an evidence base. I know that's been harder in palliative care, but we have some international work groups that really are trying to come together, see what our approaches look like, see where standardization may need to happen or where our differences are actually our strength. I think there can be a lot of variability in what palliative care looks like. So, my hope is that evidence base is coming through these collaborations. I know it's hard to have a conversation these days without talking about artificial intelligence, but that is certainly a hope. When you look at morbidity, when you look at patients with these complicated disease courses, what is pointing you in the direction of, again, a prognosis of six months or less or a patient who may do better with this disease versus not? And so, I think there's a lot to come from the artificial intelligence and big data realm. For the trainees listening out there, there is no better time to be excited about neuropalliative care and to be thinking about neuropalliative care. I said that I stumbled upon this field, and hopefully someone is inspired as well by listening to these podcasts and reading Continuum to know what this field is really about. And so, it's been exponential growth since I joined this field. We have medical students now who want to come into neuropalliative care as a profession. We have clinicians who are directors of neuropalliative care at their institutions. We have an international neuropalliative care society and neuropalliative care at AAN. And I think we are moving closer to that dream for all of us, which is that patients living with serious neurologic illness can be supported throughout that journey. High-quality, evidence-based palliative care. We're not there yet, but I think it is a possibility that we reach that in my lifetime. Dr Monteith: Well, excellent. I look forward to maybe another revision of this article with some of that work incorporated. And it's been wonderful to talk to you and to reflect on how better to approach patients that are towards the end of life and to help them with that decision-making process. Thank you so much.  Dr Chou: Yeah, thank you for having me. And we're very excited about this issue. Dr Monteith: Today.

Neurologists are privileged to act as guides for patients as they navigate the complex course of serious neurologic illnesses. Because of the impact on quality of life, personhood, and prognosis, neurologists must be able to conduct serious-illness conversations to improve rapport, reduce patient anxiety and depression, and increase the likelihood that treatment choices agree with patient goals and values. In this episode, Teshamae Monteith, MD, FAAN speaks with Jessica M. Besbris, MD, author of the article "The Approach to Serious-Illness Conversations" in the Continuum® December 2025 Neuropalliative Care issue. Dr. Monteith is the associate editor of Continuum® Audio and an associate professor of clinical neurology at the University of Miami Miller School of Medicine in Miami, Florida.

Dr Monteith: Hi, this is Dr Teshamae Monteith. Today I'm interviewing Dr Jessica Besbris about her article on the approach to serious illness conversation, which is found in the December 2025 Continuum issue on neuropalliative care. How are you? Dr Besbris: I'm doing great. Thank you so much for having me here today. Dr Monteith: Well, thank you for being on our podcast. Dr Besbris: My pleasure. Dr Monteith: Why don't we start off with you introducing yourself? Dr Besbris: Sure. So, my name is Jessica Besbris. I am a neurologist with fellowship training in palliative care, and I am currently at Cedars Sinai Medical Center in Los Angeles, where I am the director of our neuropalliative care program. Dr Monteith: Excellent. So, how did you get involved in that? Dr Besbris: Like, I think, many neurologists, I always knew I wanted to be a neurologist---or, I should say, from the moment I decided to be a doctor I knew that that was the type of doctor I wanted to be, a neurologist. So, I went into medical school with the aim of becoming a neurologist. And very quickly, when I started my clinical years, I was exposed to patients who were living with very serious illnesses. And I found myself really drawn to opportunities to help, opportunities to make people feel better, opportunities to improve quality of life in situations that on the face of it seemed really challenging, where maybe it seemed like our usual treatments were not necessarily the answer or were not the only answer. And so, I pretty quickly recognized that taking care of patients with serious illness was going to be a big part of my life as a neurologist and that palliative care was the way I wanted to help these patients and families. Dr Monteith: And you mentioned you're leading the group. So, how many colleagues do you have in the program? Dr Besbris: We have a very large palliative care group, but within neuropalliative care, it's myself and one other physician, a nurse practitioner, and a social worker. Dr Monteith: Okay, well, I know you guys are busy. Dr Besbris: Yes, we are very happy to be busy. Dr Monteith: Yes. So, let's talk about the objectives of your article. Dr Besbris: Sure. So, the goal of this article is to impress upon neurologists that it really is all of our jobs as neurologists to be having these conversations with our patients who are affected with serious illness. And then, in most areas of neurology, these conversations will come up. Whether it's giving a life changing diagnosis, or talking about treatment choices, or treatment not going the way that we had hoped, or even sometimes progression of disease or end-of-life care. These topics will come up for most of us in neurology, and really, we're hoping that this article not only makes the case that neurologists can and should be having these conversations, but that there are skills that we can teach in this article and with other resources to improve the skill level and sense of confidence that neurologists have when they enter into these conversations. Dr Monteith: Great. I read that there are some developments in the field, on organizational levels, about really making these skills part of standard of care in terms of education. So, can you speak to that? Dr Besbris: Yes. So, there have been a couple of really landmark papers and changes in the educational landscape that I think have really brought neuropalliative care in general, and serious illness conversation in particular, to the forefront. So, there were the position statements released by the American Academy of Neurology in 1996 and 2022, both of which really said, hey, all neurologists should be doing this and receive training on how to have these conversations and provide this care. And the ACGME, the Accreditation Council for Graduate Medical Education, also requires neurology residency programs to learn how to communicate with patients and families, assess goals, and talk about end-of-life care. So, there's a real structural imperative now for neurologists to learn early on how to have serious illness conversations with their patients. Dr Monteith: Great. If there's anything for our listeners to get out of this conversation, what are the essential points? Dr Besbris: If you only take away one or two things from this conversation, I hope that they're that this is an awesome responsibility to be in a moment with a patient going through something challenging, to meet them in that moment with thoughtful, honest, empathic conversations about who they are and what's important to them. And that, just like any other procedure, these are skills that can be taught so that you can feel really confident and comfortable being in these moments. Dr Monteith: Excellent. Wow. Okay, I feel your energy and your empathy already. And so, why don't we just talk about skills? What is the best way to deliver tough news? I read this wonderful chart on SPIKES protocol. Dr Besbris: Yeah, the SPIKES protocol is one really well-known way to deliver serious news. And what's nice about SPIKES is it gives a mnemonic. And as neurology learners, we all love a good mnemonic to help you really center yourself when you're entering into these conversations so that you have a structured format to follow, just like with any procedure. So, the SPIKES protocol stands for Setting: so, making sure you have the right environment; Perception, or assessing what your patient or surrogate decision maker knows already so that you know where to begin; receiving an Invitation to deliver serious news. And then K stands for Knowledge, delivering in a clear and concise way the information that you want to make sure the family or patient walk away with. E for exploring Emotion; and S for really Summarizing what's been discussed and Strategizing on next steps. I think that having these kinds of conversations, it's just like being expert in anything. When you first start learning, it's helpful to have a set of very concrete steps you can follow. And you might even think through the mnemonic as you get ready to walk into that room. And as you become more expert, the flow becomes more natural. And maybe what you do before walking in to prepare is just honing what is that headline? What is that concise statement that I'm really going to give? And the rest may start to feel more natural and less protocolized. Dr Monteith: And there are a few other mnemonics. There's the NURSE mnemonic, which I like. You know, there's a balance between saying things and sounding kind of… you know, sometimes they're like, well, how could you understand what I'm going through? Have you been through something like this? And people shy away, and they're afraid to kind of be a part of these conversations. So how do we approach that with this, a NURSE mnemonic in a way that's kind of sincere? Dr Besbris: Absolutely. So, the NURSE mnemonic, unlike SPIKES, is not a step-by-step protocol. So, NURSE is a mnemonic, but you don't go through each letter and sort of give a naming statement and then an understanding statement and then a respecting statement and so on. Nurse is really a toolkit of different types of statements that we can give in response to emotions so that when you find yourself in a situation where a patient or family member is tearful, is scared, is angry, is expressing feelings, you have some phrases ready that feel authentic to you and that you feel are going to meet the moment and allow you to empathically respond to those emotions. Because until we do that, we really can't move further in this conversation with our patients and families feeling heard and respected. So, that NURSE mnemonic, those Naming, Understanding, Respecting, Supporting and Exploring statements, are really examples of statements that we can use to meet that moment with empathy and understanding and without implying that we have walked in their shoes. We want to avoid being presumptuous and really focus on just being present and empathic. Dr Monteith: So, let's just kind of run through, I think it's really important. Let's run through some of these examples. Maybe if someone's crying hysterically, how would we respond to that? Dr Besbris: So, this is an opportunity for Naming. And I made this one, I think, in the chart, a little bit obvious, meaning that we recognize when someone is crying that they are feeling probably very sad. This is an opportunity for us to name and thus normalize that emotion. I just think something as simple as, I think anyone would be really sad hearing this. These responses are not intended to fix this emotion. I'm not trying to get someone to stop crying or to, you know, necessarily not feel sad. It's really just to say, yeah, it's normal that you're feeling sad. It's okay. I'm here with you while you're feeling sad. And I'm going to be with you no matter what you're bringing to the table. Dr Monteith: Yeah. Let's go through just a couple of others. I mean, these are really good. Dr Besbris: Sure. Maybe Respecting. Dr Monteith: Yeah. So, my Dad is a fighter. Only God, not doctors, can know the future. Dr Besbris: Yeah. So, I love giving these examples with our learners because these statements, things like my Dad is a fighter or God will bring me a miracle or you don't know the answer. Only God knows what's going to happen, I think that they give a lot of doctors a feeling of confrontation, a feeling of anxiety. And I think there are a few reasons for that. And I think one of the main ones is that they're statements that imply that we as doctors are not all-powerful and it's our patients or families sort of looking for a different locus of control, whether it's internal fortitude or a higher power. They're looking to something other than us, and maybe that makes us feel a little bit uncomfortable. And I think that sometimes physicians think that these statements imply that someone doesn't even understand what's going on. But maybe they're coming to this from a place of denial. And I would argue that when someone comes to you with a statement like my dad is a fighter or, you know, I'm looking to God to bring me a miracle or to show me the future. I think that what they're really saying is, wow, I'm really hearing that things are serious, so much so that I'm reaching for these other resources to give me strength and hope. I don't think anyone asks for a miracle if they think that a miracle is not needed, if the problem is easy to fix. And so, rather than come to these types of statements from a confrontational place of I'm the doctor and I know best, I think this is a great opportunity to show some respect and give some respecting statements. Your dad is a fighter. I don't think he could have come this far without being a fighter. Or, you know, I am so grateful that you have your faith to lean on during times like these to give you strength. These are also nice opportunities for exploring statements. For example, I'm so grateful to learn more about your dad. Can you tell me what it is that he has been fighting for all of this time? Dr Monteith: I love that. It's like a follow-up, and also validating. Dr Besbris: Yeah, it's validating. And it allows us to learn a little bit more about this person and to learn, well, is he fighting for a life that we can still achieve with our interventions to lead into the next part of a conversation? Or, is God is going to bring me a miracle? Well, tell me what a miracle looks like for you. I can't tell you how many times I thought someone was going to tell me that a miracle would be cure. And sometimes that is what comes up. But other times I hear, a miracle would be, you know, my loved one surviving long enough for the rest of the family to gather. And, you know, that is certainly something we can work towards together. Dr Monteith: So, why don't we talk a little bit about approach to goals of care discussions? They are tough, and let's just put it into perspective to the critical care team. It's time, the person's been in the ICU, the family wants everything thrown at medically. And it's to the point that the assessment is that would be medical futility. Dr Besbris: Lots to unpack there. Dr Monteith: I wanted to make it hard for you. Dr Besbris: No, no, this is good! I mean, this is something- I work in a, you know, almost one thousand-bed hospital with a massive critical care building. And so, these are not unusual circumstances at all. First of all, I would just say that goals of care conversations are not only about end-of-life care. And I make that point a few different times in the article because I think when people imagine goals of care, and one of the reasons that I think clinicians may sometimes shy away from goals of care discussions, is that they think they have to be sad, they have to be scary, they have to be about death and dying. And I would argue that, really, goals of care discussions are about understanding who a person is, how they live their life, what's most important to them. Most of these conversations should be about living. How are we going to together achieve a quality of life that is meaningful for you and treatments that are going to fit your needs and your preferences? But there is a little slice of that pie in the pie chart of goals of care discussions that is in the arena of end-of-life care. For example, ICU care with, really, the highest levels of intensity of care, and having to talk about whether that still is meeting the moment from the perspective of goals as well as the perspective of efficacy. So, from the goals standpoint, I approach these conversations just like any other goals of care conversation. Usually at this point, we're speaking to family members and not our patients because in a neurocritical care unit, if someone is that sick, they probably are incapacitated. And so, it's a moment to really sit down with family and say, please tell me about the human being lying in that bed. They can't introduce themselves. What would they tell me about themselves if they could speak right now? What kinds of things were important to them in the course of their treatment? What kind of a life did they want to live or do they want to live? So that then we can reflect on, well, can our treatment achieve that? And this process is called shared decision making. This is really where we take in data from the family, who are experts in the patient, and then our own expertise in the illness and what our treatments can achieve, and then bring all of that information together to make a recommendation that aligns with what we believe is right for a particular patient.  So, in the example that you gave, the extreme circumstance where someone is receiving maximal intensive care and we're starting to reach the point of futility, I think that we need to first really understand, well, what does futility mean for this particular patient? Is it that we as healthcare providers would not value living in the state this person is in? Or is it that the treatments truly cannot physiologically keep them alive or meet their stated goals? If it's the first one, that I wouldn't want to be on machines unconscious, you know, at the end of my life, well, I have to set that aside. It's really about what this patient wants. and if the family is telling you they valued every breath, every moment, and if we have care that can achieve that, we should continue to offer and recommend that care. And as healthcare providers, it is so important that we do explain when treatments are not going to be able to physiologically meet a patient's needs or achieve their goals. And that's where we can say, I'm going to continue to do everything I can, for example, to, you know, keep your loved one here for these meaningful moments. And we are at a point where performing CPR would no longer be able to restart his heart. And I just wanted to let you know that that's not something that we're going to do because I have an obligation not to provide painful medical treatments that will not work. So, my approach to futility is really different than my approach to shared decision-making because in the context of objective futility, it's not about necessarily- it's not about decision-making, it's not about shared decision-making as much as it is explaining why something is simply not going to work. Does that make sense? Dr Monteith: Absolutely. And what I love in your article is that, you know, you go beyond the skills, but also potential communication challenges---for example, patients' neurologic status, their ability to understand complex communication, or even cultural differences. So, can you speak about that briefly? Dr Besbris: Absolutely. In the world of neurological serious illness, it is incredibly common for our patients to face challenges in communication. That might be because they are aphasic, because they have a motor speech deficit, it might be because they're intubated, it might be because their capacity is diminished or absent. And so, there are a lot of challenges to keeping patients in these conversations. And in the article, I summarize what those challenges can look like and some strategies that we can use to continue to engage our patients in these conversations to the greatest extent possible and also turn to their surrogate decision makers where the patients themselves are no longer able to participate or participate fully. In terms of cultural considerations, I mean, there could be an entire article or an entire Continuum just on cultural considerations in neurology and in serious illness communication. And so, the key points that I really tried to focus on were exploring from a place of cultural humility what the beliefs and practices of a particular patient and family are in their cultural context, to ask questions to help you understand how those cultural differences may impact the way you approach these conversations. And being sensitive to folks with limited English proficiency, to ensure that we are using medical interpreters whenever possible. Dr Monteith: Excellent. Well, there's so much in the article. There's already so much that we just discussed, but our listeners are going to have to go to the article to get the rest of this. I do want to ask you to just kind of reflect on, you know, all the different cases and experiences that you have, and just, if you can give us a final remark? Dr Besbris: I can think of a number of cases that I've seen in my work as both an inpatient and outpatient neuropalliative provider where I've seen patients after strokes in the hospital with uncertain prognosis, whose families were struggling with a decision around feeding tubes. And where we have made a determination based on goals; for example, to pursue what's called a time-limited trial, to say let's place a feeding tube, let's meet again in the clinic in a few months after some rehab and let's just see, is this meeting this patient 's goals and expectations? I have been pleasantly surprised by the number of patients who have walked into my office after a period of rehabilitation who have regained the ability to eat, who are living an acceptable quality of life, and who have expressed gratitude for the work that I did in eliciting their goals, helping support their families. And some of whom have even come in and said, now that I'm doing better, I'd really like to do an advance directive to better guide my family in the future. People asking for more goals of care discussions, having seen how successful and helpful these conversations have been. Dr Monteith: Great. That's really life-altering for that patient, the family, so many people. Thank you so much for the work you do and for writing this great article and sharing all of this that we really need to learn more about. Dr Besbris: It's been a privilege.

The focus on symptom management and quality of life is a key aspect of helping these patients. But how many of us are comfortable starting the conversation about palliative care or care at the end of life? Today we have the opportunity to speak with a leading expert on neuropalliative care, Dr Maisha Robinson, about how we can better integrate neuropalliative care into our practices. Dr Jones: This is Dr Lyell Jones, Editor-in-Chief of Continuum. Thank you for listening to Continuum Audio.

Dr Jones: This is Dr Lyell Jones, Editor-in-Chief of Continuum: Lifelong Learning in Neurology. Today I'm interviewing Dr Maisha Robinson, who is Continuum's Guest Editor for our latest issue of Continuum on neuropalliative care, and our first-ever issue fully dedicated to this topic. Dr Robinson is an assistant professor of neurology at Mayo Clinic in Florida, where she is Chair of the Division of Palliative Medicine, and she also serves on the AAN Board of Directors as Chair of the Member Engagement Committee. Dr Robinson, welcome. Thank you for joining us today. Why don't you introduce yourself to our listeners? Dr Robinson: Well, Dr Jones, thank you for having me. Really a pleasure to be here. I'm Maisha Robinson at the Mayo Clinic in Jacksonville, Florida. I spent my time as a neurohospitalist, a general palliative care physician, and a neuropalliative care physician. Dr Jones: So, this is a topic that at Continuum, we have heard about from subscribers for a long time requesting a fully dedicated issue to palliative care. And we've titled this neuropalliative Care. So, we want to respond to our subscribers and bring them content that they're interested in. I also think that palliative medicine is a big education gap in our specialty of neurology and something that we have room to improve on. So, let's start with the basics, Dr Robinson. Palliative medicine has been around for a long time, but this concept of "neuropalliative care" feels relatively new. What is neuropalliative care? Dr Robinson: That's a great question. Generally, what I would say is palliative care, first of all, is really just a specialty that focuses on trying to improve quality of life for people that have a serious or advanced medical condition. And neuropalliative care is really palliative care for people with neurologic conditions. And you'll see a number of neurologists doing neuropalliative care, but also there are internists as well, and people from other specialties, who focus on patients with neurologic disease and really trying to improve their quality of life. Dr Jones: Got it. And so, it's really the principles of palliative medicine in a specialty-specific context, which I think is important for us given the prevalence of chronic disease in our specialty. And I was obviously reading through these articles in this issue, and in the really wonderful articles, there are some themes that came up multiple times in various different articles. And one of them was obviously the importance of communication with patients and families. I think, and I'm speaking a little bit from personal experience here, many physicians feel uncomfortable bringing up the discussion of palliative care. And I'm sure that is something that reflects on your practice, too. How often do you have a patient who shows up to clinic and they ask you, why am I here? Dr Robinson: It happens all the time, because colleagues who are referring patients are nervous to tell them that they're sending them to palliative care. But we try to tell people it's really just to normalize it, to say that the palliative care team is going to see you, they're going to help with some symptoms, they're going to help you think about big picture, and they're going to be sort of an added layer of support to your team. And I think if people approach it from that standpoint, then patients and family members will say, that sounds great, I need a little extra support. Dr Jones: So, I think most neurologists have a threshold at which they would feel more comfortable having specialty support, having a palliative medicine specialist to help them in symptom management with the patient. For the palliative care that they provide themselves---and we want our subscribers to read this issue and feel more comfortable with delivering some palliative care on their own---how would you encourage them to begin that conversation? How should they initiate that conversation with a patient about working more toward palliative management of symptoms? Dr Robinson: So, one of the things we recommend is really introducing an approach to palliative care very early in the disease process. So, discussions about big picture and goals of care, discussions about who might help make medical decisions if the person can't make them for themselves. Those kinds of things can be discussed very early on. And in fact, that's palliative care. And then they can talk to patients more about the fact that as the disease progresses, there may be an additional team that can help walk along alongside the neurologist in helping you prepare for what's to come. You know, I think it's very important for patients and family members who feel like you're not abandoning them, but you're adding additional resources. And so, I like the way that we often will suggest to people to say partner or collaborate or bring in extra resources with the palliative care team. I think patients and family members will respond to that. Dr Jones: Yeah. So, by talking about it early, you kind of, at least, help to avoid that problem of the patient perceiving the introduction of palliative care as the quote-unquote "giving-up problem." Is that right? Dr Robinson: Correct. Because we also don't want to see people who are just being referred to us for end-of-life care. Palliative care is about much more than that. But if patients will Google palliative care, they may see hospice come up. And so, introducing the concept early and discussing some palliative topics early will allow the patient and family members to think that, okay, this isn't because I'm at the end of life. This is just because my clinician wants to make sure that I have all the bases covered. Dr Jones: This was also mentioned in several of the articles, the studies that have shown how frequently palliative care is initiated very near the end of life, which is usually, I think, perceived as a missed opportunity, right? To not wait so long to take advantage of what palliative care has to offer. Dr Robinson: That's correct. And the benefit of palliative care is that oftentimes we work alongside an interdisciplinary team, a team that could be quite helpful to patients and their support systems throughout the course of the disease. So, we have chaplains, we have nurses, we often have other clinicians, advanced practice providers as well, who work with us. We have spiritual advisors as well. And the patients and family members could benefit from some of those resources throughout the course of the disease. Who they might need to meet with may vary depending on what the disease is and how they're doing. But there's definitely some benefit to having a longitudinal relationship with the palliative care team and not just seeking them out at the end of life. Dr Jones: So- that's very helpful. So, it'll obviously vary according to an individual provider's level of comfort, right, where they're comfortable providing certain palliative management care versus when they need to have some assistance from a specialist. Are there types of care or are there certain thresholds that you say, wow, this patient really should go see a specialist in palliative medicine or neuropalliative care? Dr Robinson: So, I think that if there are, for instance, refractory symptoms, where the neurologist has been working with a patient for a while trying to manage certain symptoms and they're having some challenges, that person may benefit from being referred to palliative care. If patients are being hospitalized multiple times and frequently, that may suggest that a good serious-illness conversation may be necessary. If there are concerns about long-term artificial nutrition, hydration, or functional and cognitive decline, then some of those patients have benefited from palliative care. Not only the patient, but also the caregiver, because our team really focuses on trying to make sure that we're walking through the course of disease with these patients to ensure that all of the needs are managed both for the patient and the family member. Dr Jones: Got it. And that's very helpful. And I know that we talk about a lot of these decisions happening in an ideal environment when there's good access to the neurologist and good access to a palliative medicine specialist or even a neuropalliative medicine expert. In your general sense, I- and maybe we'll talk a little bit here in a minute or two about the growing interest in neuropalliative care. But in terms of access, in terms of availability of really, truly neuropalliative expertise, what is your sense of how widely available that is in the US? Dr Robinson: There's a shortfall of palliative care clinicians in the United States. Everybody who needs a palliative care clinician won't have access to one. And I think your point about the primary palliative care is so important. That's really what we encourage all clinicians, neurologists, neurosurgeons, even, physiatrists, the neurology care team members need to be comfortable with at least initiating some of these conversations. Because, to your point, not everyone's going to have access to a palliative care physician. But by reading issues such as this one, attending some courses---for instance at the American Academy of Neurology meetings---, doing some online trainings, those types of things can be helpful to bring any neurology clinician up to speed who certainly may not have access to a palliative care physician. Dr Jones: So, I know---and this is in part from my own conversations with patients in my own practice---there are a number of fears that patients have when they have a chronic disease, something that's progressive or something that we don't have a curative treatment for. But I think one of, if not the most common fear among patients is pain, and pain that can't be managed adequately during the course of chronic illness or at the end of life. One of the interesting concepts that I saw mentioned in a few of the articles in this issue is this concept of total pain. So, not just the somatic pain that I think we tend to think of as clinicians and patients tend to think of as patients, but a more holistic definition of pain. Walk us through that and how that relates to palliative medicine. Dr Robinson: So, Dame Cicely Saunders, the modern-day founder of palliative medicine, really described this biopsychosocial model for pain. And so, you're right, it's not just physical pain, but it's psychological pain, it's spiritual pain. And oftentimes when we are taking care of patients with neurologic disease, they may have some physical pain, but a lot of them are thinking about, for instance, the things that they will miss, which may cause some internal discomfort. Things that they're grieving, the life they thought they were going to have, the person that they used to be, the life they used to have, and what they anticipated their life as being. And some of that can cause people to have not only the spiritual discomfort, but also some psychological discomfort as well. And so, when we're thinking about how to provide rehensive care to these patients, we have to be thinking about all of these aspects. Dr Jones: It's really helpful. And I guess the more you can identify those, the more you can either help yourself or find the right expert to help the patient. I thought that was an interesting expansion of, of my view of how to think about pain. And another observation that came up in several of the articles was a lack of high-quality clinical trial evidence to inform a lot of the interventions in neuropalliative care. Some of them are common-sense, some of them are based on clinical experience or expert advice. In your own practice, if there was one key knowledge gap to close---in other words, if there was one pivotal trial that we could do to answer one question in helping patients with chronic neurologic disease---what would you say is the main gap? Dr Robinson: I think the real gap is, who needs palliative care and when? That seems very simple. We have tried things such as automatic triggers for palliative care, for instance, in patients with ALS, or we've said that maybe all glioblastoma patients should see palliative care. But is that true? Are we utilizing the resources in the best possible way that we can? We're not sure. And so, you'll see these practices doing things all a little bit different because we don't have a best practice and it's not really standardized about when people should see palliative care, or why, for instance, they should see palliative care, or who should see palliative care. And I think if we could help drill that down, we can provide some better guidance to our colleagues about when and why and who should see palliative care. Dr Jones: It's a really kind of a fundamental, foundational, who needs the service to begin with or who needs to care. Okay, that's- that is a big gap. So, one of the interesting concepts that I read- and it was in Benzi Kluger's article on neuropalliative care for patients who have movement disorders. I think it's a concept that is interesting, really, maybe in the management of patients with a lot of different chronic, progressive neurologic diseases. And it's this idea of stealing victories or bringing joy to patients. In other words, not just managing or trying to minimize some of the negative aspects or symptoms of disease, but looking for opportunities to bring something positive to their experience or improving their quality of life. Tell us a little more about that, because I think that's something patients would appreciate, but I think neurologists would appreciate that, too. Dr Robinson: Dr Kluger loves to talk about sustaining and finding joy in patients who have really serious or advanced neurologic conditions. He likes to talk about stealing victories, which can relate to the fact that patients and their loved ones can find even some benefit despite having a serious or advanced neurologic condition. Neurologists and neurology clinicians also can steal victories in their patients when they notice, for instance, that they've gained a new skill, and they've lost a skill that they used to love because of the advancing disease. And this is just an opportunity for not only the patients and family members, but also the care providers to recognize that in the midst of decline, there are positive things to be found. Dr Jones: I think it gives patients a sense of maybe reclaimed autonomy when they can say, well, there's maybe nothing I can do to cure this disease in the conventional sense, but I can maybe go on this trip with my family, which has been something I've always wanted to do. Or, I can do these things, so I can attend certain events that I want to. And I think that autonomy and independence aspect of that, I think that I think that was really meaningful and something that I'm going to bring back to my own practice in my care of patients who have ALS, for example. When you think about neuropalliative care---and you've been a leader in this area, Dr Robinson---what do you think the biggest change in neuropalliative care has been over the last few years? Dr Robinson: I think there's a growing cohort of people who are recognizing that there is some benefit in having dedicated specialists who focus on palliative care for patients with neurologic disease. When I said I was going to do neuropalliative care, somebody asked me, why would a neurologist be interested in palliative care? Over the last decade and a half, we've seen that shift. And not only are our colleagues recognizing the benefit, but also patients and caregivers are. Some are even asking for palliative care. I think people are recognizing that not only having their primary neurologist or neurology clinician taking care of them, they have this extra layer of support, and this extra team really focused on quality-of-life issues can be beneficial. Dr Jones: So, one of the things that I think you and I have both seen, Dr Robinson, is a growing interest among neurology trainees in palliative medicine. And maybe that's anecdotal, but in my own practice, I've seen more and more trainees express an interest in this. For neurology residents who are interested in this as a component of or maybe a focus of their career, what would you recommend to them? How should they go about this? Dr Robinson: Yes, it used to be that every neurology resident interested in palliative care would call me or email me or send me a message, but now there are so many that I can't keep up. We're excited about the growing number of people interested in neuropalliative care. What I would say to those people is that you can really try to hone your skills by, for instance, doing a rotation with the palliative care team at your hospital, if there is one. If there isn't one, you might even ask to spend some time with the local hospice agency, which may be helpful to you. If you're attending some of the national meetings---for instance, the American Academy of Neurology meeting---you may want to go to a course and learn a little bit about palliative care. There are a couple that are offered every year. There is an education opportunity for education in palliative and end-of-life care as well. And so, there are a number of resources that you can find in addition to this issue of Continuum as well. Dr Jones: I find it gratifying that trainees ask about this. And I'm sorry, I think I've probably sent a bunch of trainees your way for advice about this, and you've been incredibly generous with your time and expertise. So, I find it very gratifying that our neurology trainees are interested in this area, because it's an important area of medicine. It's also probably a challenging practice just from the cognitive load and the emotional load of caring for patients who are moving through a progressive illness. What is your thinking about how to have a sustainable career in palliative medicine? What is your approach to that? Is it for everyone? Dr Robinson: Yeah, the issue with palliative care is that we do see some very challenging situations, and frankly some very sad situations. But I actually love what I do because I think that we're helping patients and their family members during very, very difficult times. I feel like this is why I went to medical school, to try to be there for people when they need me the most. The way that I think about it is, the patients and family members will be going through this anyway. We're trying to help improve their quality of life as they're going through it. And what you might find interesting is that these patients are so grateful. And their loved ones, they're so grateful. Even if they're nearing the end of life, just to have someone who's helping them see that, for instance, the pain could be better, or that they have more resources for the loved ones to be able to take care of them. And so, I think that helps sustain us, realizing that we are really having a positive benefit on the patients and also their family members. Dr Jones: Well, I think that's a great point to end on. And these are patients who need help. Even if we don't have a curative therapy, they do need support. And that's an important service and a function and an important facet of our profession. So, Dr Robinson, I want to thank you for joining us, and I want to thank you for such a great discussion of neuropalliative care. I learned a lot from our conversation today. I've learned a lot reading the articles and the experts that you put together. This is an important topic. I'm really grateful to you to having assembled this team of expert authors and put together an issue that I think will be really important for not only our junior readers, but also our more experienced subscribers as well. Dr Robinson: Thank you, Dr Jones, for the opportunity.

Dr Nevel: Hello, this is Dr Kate Nevel. Today I'm interviewing Dr Divya Jayaraman about her article on dystrophinopathies, which she wrote with Dr Partha Ghosh. This article appears in the October 2025 Continuum issue on muscle and neuromuscular junction disorders. Divya, welcome to the podcast, and please introduce yourself to the audience. Dr Jayaraman: Thank you so much, Dr Nevel. My name is Divya, and I am an assistant professor of Neurology and Pediatrics at Columbia University Irving Medical Center, and also an attending physician in the Pediatric Neuromuscular program there. In that capacity, I see patients with pediatric neuromuscular disorders and also some general pediatric neurology patients and also do research, primarily clinical research and clinical trials on pediatric neuromuscular disorders. Dr Nevel: Wonderful. Thank you for sharing that background with us. To set us on the same page for our discussion, before we get into some more details of the article, perhaps, could you start with some definitions? What comprises the dystrophinopathies? What are some of the core features? Dr Jayaraman: So, the dystrophinopathies, I like that term because it is a smaller subset from the muscular dystrophies. The dystrophinopathies are a spectrum of clinical phenotypes that are all associated with mutations in the DMD gene on chromosome X. So, that includes DMD---or, Duchenne muscular dystrophy---, Becker muscular dystrophy, intermediate muscular dystrophy (which falls in between the two), dilated cardiomyopathy, asymptomatic hyperCKemia, and manifesting female carriers. In terms of the core features of these conditions, so, there's some variability, weakness being prominent in Duchenne and also Becker. The asymptomatic hyperCKemia, on the other hand, may have minimal symptoms and might be found incidentally by just having a high CK on their labs. They all will have some degree of elevated CK. The dilated cardiomyopathy patients, and also the Becker patients to a lesser degree, will have cardiac involvement out of proportion to skeletal muscle involvement, and then the manifesting carriers likewise can have elevated CK and prominent cardiac involvement as well as some milder weakness. Dr Nevel: Now that we have some definitions, for the practicing neurologists out there, what do you think is the most important takeaway from your article about the dystrophinopathies? Dr Jayaraman: I like this question because it suggests that there's something that, really, any neurologist could do to help us pick up these patients sooner. And the big takeaway I want everyone to get from this is to check the CK, or creatine kinase, level. It's a simple, cheap, easy test that anyone can order, and it really helps us a lot in terms of setting the patient on the diagnostic odyssey. And in terms of whom you should be thinking about checking a CK in, obviously patients who present with some of the classic clinical features of Duchenne muscular dystrophy. This would include young boys who have toe walking, as they're presenting, sign; or motor delayed, delayed walking. They may have calf hypertrophy, which is what we say nowadays. You might have seen calf pseudohypertrophy in your neurology textbooks, but we just say calf hypertrophy now. Or patients can often have a Gowers sign or Gowers maneuver, which is named after a person called Gowers who described this phenomenon where the child will basically turn over and use their hands on the floor to stand up, usually with a wide-based gait, and then they'll sort of march their hands up their legs. That's the sort of classic Gowers maneuver. There are modified versions of that as well. So, if anyone presents with this classic presentation, for sure the best first step is to check a CK. But I would also think about checking a CK for some atypical cases. For example, any boy with any kind of motor or speech delay for whom you might not necessarily be thinking about a muscle disorder, it's always good practice to check a CK. Even a boy with autism for whom you may not get a good clinical exam. This patient might present to a general pediatric neurology clinic. I always check a CK in those patients, and you'll pick up a lot of cases that way. For the adult folks in particular, the adult neurologist, a female patient could show up in your clinic with asymptomatic hyperCKemia. And I think it's an important differential to think about for them because this could have implications not just for their own cardiac risks, but also for their family planning. Dr Nevel: So, tell us a little bit more about the timing of diagnosis. Biggest takeaway: check a CK if this is anywhere on your radar, even if somewhat of an atypical case. Why is it so important to get kiddos started on that diagnostic odyssey, as you called it, early? Dr Jayaraman: This is especially important for kids because if they especially get a Duchenne muscular dystrophy diagnosis, you might be making them eligible for treatments that we've had for some time, and also treatments that were not available earlier that hinge on making that diagnosis. So, for example, people may be skeptical about steroids, but there's population data to suggest that initiation and implementation of steroids could delay the onset of loss of ambulation as much as three years. So, you don't want to deprive patients of the chance to get that. And then all the newer emerging therapies---which we'll be talking about later, I'm sure---require a Duchenne muscular dystrophy diagnosis. So, that's why it's so important to check a CK, have this on your radar, and then get them to a good specialist. Dr Nevel: I know that you alluded already, or shared a few of the kind of exam paroles or findings among patients with dystrophinopathy. But could you share with us a little bit more how you approach these patients in the clinic who are presenting with muscle weakness, perhaps? And how do you approach this or think about this in terms of ways to potentially differentiate between a dystrophinopathy versus another cause of motor weakness or delay? Dr Jayaraman: It's helpful to think through the neuraxis and what kinds of disorders can present along that neuraxis. A major differential that I'm always thinking about when I'm seeing a child with proximal weakness is spinal muscular atrophy, which is a genetic anterior horn cell disorder that can also present in this age group. And some of the key differences there would be things like reflexes. So, you should have dropped reflexes in spinal muscular atrophy. In DMD, surprisingly, they might have preserved Achilles reflexes even if their patellar reflexes are lost. It may only be much later that they go on to lose their Achilles reflex. So, if you can get an Achilles reflex, that's quite reassuring, and if you cannot, then you need to be thinking about spinal muscular atrophy. They can both have low muscle tone and can present quite similarly, including with proximal weakness, and can even have neck flexion weakness. So, this is an important distinction to make. The reason for that is, obviously there are treatments for both conditions, but for spinal muscular atrophy, timing is very, very important. Time is motor neurons, so the sooner you make that diagnosis the better. Other considerations would be the congenital muscular dystrophies. So, for those that they tend to present a lot younger, like in infancy or very early on, and they can have much, much higher CKS in that age range than a comparable Duchenne or Becker muscular dystrophy patient. They can also have other involvement of the central nervous system that you wouldn't see in the dystrophinopathies, for example. My mnemonic for the congenital muscular dystrophies is muscle-eye-brain disease, which is one of the subtypes. So, you think about muscle involvement, eye involvement, and brain involvement. So, they need an ophthalmology valve. They can have brain malformations, which you typically don't see in the dystrophinopathies. I think those are some of the major considerations that I have. Obviously, it's always good to think about the rest of the neuraxis as well. Like, could this be a central nervous system process? Do they have upper motor neuron signs? But that's just using all of your exam tools as a neurologist. Dr Nevel: Yeah, absolutely. So, let's say you have a patient in clinic and you suspect they may have a dystrophinopathy. What is your next diagnostic step after your exam? Maybe you have an elevated CK and you've met with the patient. What comes next? Dr Jayaraman: Great question. So, after the CK, my next step is to go to genetics. And this is a bit of a change in practice over time. In the past we would go from the CK to the muscle biopsy before genetic testing was standard. And I think now, especially in kids, we want to try and spare them invasive procedures where possible. So, genetic testing would be the next step. There are a few no-charge, sponsored testing programs for the dystrophinopathies and also for some of the differential diagnosis that I mentioned. And I think we'll be including links to websites for all of these in the final version of the published article. So, those are a good starting point for a genetic workup. It's really important to know that, you know, deletions and duplications are a very common type of mutation in the DMD gene. And so, if you just do a very broad testing, like whole exome, you might miss some of those duplications and deletions. And it's important to include both checking for duplications and deletions, and also making sure that the DMD gene is sequenced. So always look at whatever genetic test you're ordering and making sure that it's actually going to do what you want it to do. After genetics, I think that the sort of natural question is, what if things are not clear after the genetics for some reason? We still use biopsy in this day and age, but we save it for those cases where it's not entirely clear or maybe the phenotype is a little bit discordant from the genotype. So, for mutations that disrupt the reading frame, those tend to cause Duchenne muscular dystrophy, whereas mutations that preserve the reading frame tend to cause Becker muscular dystrophy. There are some important exceptions to this, which is where muscle biopsy can be especially helpful in sorting it out. So, for example, there are some early mutations early in the DMD gene where, basically, they find an alternate start codon or an initiation codon to continue with transcription and translation. So, you end up forming a largely functional, somewhat truncated protein that gives you more of a milder Becker phenotype. On the other hand, you can have some non-frameshift or inframe mutations that preserve the reading frame, but because they disrupt a very key domain in the protein that's really crucial for its function, you can actually end up with a much more severe Duchennelike phenotype. So, for these sorts of cases, you might know a priori you're dealing with them, but might just be a child who is who you think has DMD has a mutation that's showed up on testing. There isn't enough in the literature to point you one way or another, but they look maybe a little milder than you would expect. That would be a good kid to do a biopsy in because there are treatment decisions that hinge on this. There are treatments that are only for Duchenne that someone with a milder phenotype would not be eligible for. Dr Nevel: So, that kind of stepwise approach, but maybe not all kids need a muscle biopsy is what I'm hearing from you. If it's a mutation that's been well-described in the literature to be fitting with Duchenne, for example. Dr Jayaraman: Absolutely. Dr Nevel: So, after you confirm the diagnosis through genetic testing---and let's say, you know, whether or not you do a muscle biopsy or not, after you know the diagnosis is a dystrophinopathy---how do you counsel the families and your patients? What are the most important points to relay to families, especially in that initial phase where the diagnosis is being made? Dr Jayaraman: This is a lot of what we do in pediatric neurology in general, right? So, I actually picked up this approach from the pediatric hematology oncology specialists at Boston Children's. They had this concept of a day-zero conversation, which is the day that you disclose the life-changing diagnosis or potentially, at some point, terminal diagnosis to a family. And some of the key components of that are a not beating around the bush, telling them what the diagnosis is, and then letting them have whatever emotional response they're going to have in the moment. And you may not get much further than that, but honestly, you want them to take away, this is what my child has. I did not do anything to cause this, nor could I have done anything to prevent this. Because often for these genetic conditions, there's a lot of guilt, a lot of parental guilt. So, you want to try and assuage that as much as possible. And then to know that they're not going to be alone on this journey; that, you know, they don't have to have it all figured out right then, but we can always come back and answer any questions they have. There's going to be a whole team of specialists. We're going to help the family and the kid manage this condition. Those are sort of my big takeaways that I want them to get. Dr Nevel: Right. And that segues into my next question, which is, who is part of that team? I know that these teams that help take care of people with dystrophinopathies and other muscle disorders can be very large teams that span multiple specialists. Can you talk a little bit more about that for this group of patients? Dr Jayaraman: Of course. So, the neuromuscular neurologist, really, our role is in coordinating the diagnosis, the initiation of any disease-specific treatments, and coordinating care with a whole group of specialists. So, we're sort of at the center of that, but everyone else is equally important. So, the other specialists include physical therapists; occupational therapists; rehab doctors or physiatrists; orthotists who help with all of the many braces and other devices that they might need, wheelchairs; pulmonology, of course, for managing the respiratory manifestations of this. It becomes increasingly important over time, and they are involved early on to help monitor for impending respiratory problems. Cardiac manifestations, this is huge and something that you should be thinking about even for your female carriers, the mother of the patient you're seeing in the clinic, or your patient who comes to adult clinic with asymptomatic hyperCKemia. if you end up making a diagnosis of DMD carrier for those patients, or if you make a Becker diagnosis, the cardiac surveillance is even more important because the cardiac involvement can be out of proportion to the skeletal muscle weakness. And of course, extremely important for the Duchenne patients as well. Endocrinologists are hugely important because in the course of treating patients with steroids, we end up giving them a lot of iatrogenic endocrinologic complications. Like they might have delayed puberty, they might have loss of growth, of height; and of course metabolic syndrome. So, endocrinology is hugely important. They're also important in managing things like fracture prevention, osteoporosis, prescribing bisphosphonates if necessary. Nutrition and GI are also important, not just later on when they might need assistance to take in nutrition, whether that's through tube feeds, but also earlier on when we're trying to manage the weight. Orthopedics, of course, for the various orthopedic complications that patients develop. And then finally, a word must be said for social work and behavioral and mental health specialists, because a lot of this patient population has a lot of mental health challenges as well. Dr Nevel: After you give the diagnosis, you've counseled the patient and families and you've had those kind of initial phase discussions, the day-zero discussion, when you start getting into discussions or thoughts about management, disease-specific medication. But what are the main categories of the treatment options, and maybe how do you kind of approach deciding between treatment options for your patients? Dr Jayaraman: So, there are two broad categories that I like to think about. So, one is the oral corticosteroids and oral histone deacetylase, or HDAC inhibitors, which share the common characteristic that they are non-mutation specific. And within corticosteroids, patients now have a choice between just Prednisone or Prednisolone, or Deflazacort or Vermilion. The oral HDAC inhibitors are newly FDA-approved as a nonsteroidal therapy in addition to corticosteroids in DMD patients above six years of age. I would say we're in the early phase of adoption of this in clinical practice. And then the other big category of treatment options would be the genetic therapies as a broad bucket, and this would include gene therapy or gene replacement therapy, of which the most famous is the microdystrophin gene therapy that was FDA-approved first on an accelerated approval basis for ages four to eight, and then a full approval in that age group as well as an accelerated approval for all comers, essentially, with DMD. This is obviously controversial. Different centers approach this a bit differently. I think our practice at our site has been to focus on the ambulatory population, just thinking about risk versus benefit, because the risks are not insignificant. So really this is something that should be done by experienced sites that have the bandwidth and the wherewithal to counsel patients through all of this and to manage complications as they arise with regular monitoring. And then another class that falls within this broader category would be the Exon-skipping therapies. So as the name suggests, they are oligonucleotides that cause an Exon to be skipped. The idea is, if there is a mutation in a particular Exon that causes a frame shift, and there's an adjacent Exon that you can force skipping of, then the resulting protein, when you splice the two ends together, will actually allow restoration of the reading frame. I think the picture I want to paint is that there's a wide range of options that we present to families, not all of which everyone will be eligible for. And they all have different risk profiles. And I really think the choice of a particular therapy has to be a risk-benefit decision and a shared decision-making process between the physician and the family. Dr Nevel: What is going on in research in this area? And what do you think will be the next big breakthrough? I know before we started the recording you had mentioned that there's a lot of things going on that are exciting. And so, I'm looking forward to hearing more. Dr Jayaraman: Of course. So, I'll be as quick as I can with this. But I mentioned that next-generation Exon skipping therapies, I think the hope is that they will be better at delivering the Exon skipping to the target tissue and cells and that they might be more efficacious. I'm also excited about next-generation gene therapies that might target muscle more specifically and hopefully reduce the off-target effects, or combination use of gene therapies with other immunosuppressive regimens to improve the safety profile and maybe someday allow redosing, which we cannot do currently. Or potentially targeting the satellite cells, which are the muscle stem cells, again, to improve the long term durability of these genetic therapies. Dr Nevel: That's great, thank you for sharing.

Dr Albin: Hello everyone, this is Dr Casey Albin. Today I'm interviewing Dr Paloma Gonzalez-Perez about her article on myotonic dystrophy, which appears in the October 2025 Continuum issue on muscle and neuromuscular junction disorders. Welcome to the podcast, Dr Gonzalez-Perez. I'd love for you to introduce yourself to our listeners. Dr Gonzalez-Perez: Thank you very much for the invitation. My name is Paloma Gonzalez-Perez. I'm a neuromuscular neurologist at Massachusetts General Hospital in Boston since 2018. And I'm originally from Spain. I did residency there and also here in Iowa City. And then I did the neuromuscular fellowship here at Mass General Brigham, and then I stayed here as a faculty. So, my focus is myopathies, and more specifically muscular dystrophies, and more particularly myotonic dystrophy, which is what we are going to talk today. Dr Albin: Wonderful. And this is a really fantastic tour de force article about myotonic dystrophy. And in reading your article, it really did stand out to me that these myotonic dystrophies are probably under-recognized. And so, I was hoping that, just to start, you could tell us a little bit about, what is a myotonic dystrophy, and how should we sort of situate that within the larger context of all muscular dystrophies? Dr Gonzalez-Perez: Yes, so muscular dystrophies, we have many of them, right? And mostly affecting the skeletal muscle. And basically, the definition of muscular dystrophy is a genetic or inherited muscle disease that causes a progressive muscle weakness. And also, in the muscle biopsies of patients with muscular dystrophies, we see some fractures that are characteristic of this category of muscle diseases, such as, for example, the nuclei of the muscle fibers are in the center---that's what we call internal nuclei---or maybe fat infiltration or increased connective tissue or a variability in the size of the muscle fibers. So, now in the last few years, the genetic testing is more accessible to us. So, we don't need muscle biopsies all the time to diagnose patients with muscular dystrophy. So many times, we go directly to genetic testing. And this is basically the category of muscular dystrophies. Myotonic dystrophy is very fascinating muscular dystrophy in the sense that many times not only affect the skeletal muscle, but other organs can be affected. And it is true that other muscular dystrophies can affect other organs such as, for example, the brain and the heart, which is something that we always have in mind as a clinician to make sure this muscular dystrophy affect the heart or affect the brain, because it is important for patient care. But myotonic dystrophy actually can affect any organ in the body. I think it is one of these muscular dystrophies in which there is a multisystem involvement of the body. So, the immune, immunological system can be affected and the endocrine system can be affected, the GI system can be affected. In addition to, obviously, to the brain, to the heart, to the skeletal muscle. And sometimes that is why it is under-recognized because of course, if there is a very severe phenotype, maybe the patient comes very easily to a neurologist who is very familiar with myotonic dystrophy. But if the phenotype is a little bit milder, and maybe it doesn't affect much the skeletal muscle. So, these patients probably are in the care of other specialists, such as, for example cardiology or GI doctors, and obviously these specialists are not really aware of this muscular dystrophy. So, I think it is a complex disease because it is very variable in phenotype, can affect many organs and can be also mild. Dr Albin: That is fantastic. That is just a wonderful overview of, really, muscular dystrophy. One of the things I was really curious about: the name includes myotonia. Is myotonia, like, always present, or is that a little bit misleading? Dr Gonzalez-Perez: Yeah. I would say that it is a little bit misleading---maybe not too much in myotonic dystrophy type one, because it is true that in adults with myotonic dystrophy type one, many times they have the myotonia, but not many times they complain about the myotonia. This is the thing. So, it is a diagnostic clue that we have at bedside when we ask the patient, for example, to squeeze the hands and then release and we see the myotonia there. And then, obviously, this can actually give you the diagnosis at bedside, but the patients usually don't come to the clinic complaining of this myotonia, which is delaying the relaxation of the muscles. Sometimes they don't- they are not bothered by that. They don't need treatment for that. But it is a very important clue at bedside. I have to say, adults, myotonic dystrophy type one, because the congenital myotonic dystrophy type one you don't see myotonia, clinical myotonia. These babies, right, are born with severe muscle weakness and we don't see myotonia. And then myotonic dystrophy type two, many patients don't have clinical myotonia. And then, you know, the absence of myotonia, the absence of this delay in the muscle relaxation doesn't rule out a myotonic dystrophy, and especially doesn't rule out a myotonic dystrophy type two. Dr Albin: Fantastic. So probably is going to be a feature of the adult-onset type one. May or may not be present in type two. And then the congenital forum where children are presenting as infants, they're not going to tell you that, oh, I have delayed relaxation. That's not going to be part of that. Dr Gonzalez-Perez: Exactly. Dr Albin: This is one of those things that I think, unless you're in neuromuscular clinic, you might not think to ask people about. Maybe the patient isn't actually saying, oh, I have this delayed reaction. How do you get them to give you that history? Like, what are the questions that you ask? Dr Gonzalez-Perez: Sometimes I will say, do your hands get locked? You know, this could be the first question that they noticed something there, and then they can give you maybe the clue. But actually, it's the exam more than the question. I will say it's more do the exam and, you know, intentionally test for myotonia. And you test for spontaneous myotonia and percussion myotonia. So spontaneous myotonia, we tell the patient to squeeze the hands very strongly and then open the hands quickly. And then if they cannot open the hands quickly, this is a delay in muscle relaxation. We call it grip myotonia, spontaneous grip myotonia. Or sometimes close your eyes very, very, very strongly and then open the eyes quickly. And if they have this delay in the eye opening, we call it eyelid myotonia. This eye is spontaneous myotonia, you don't touch the patient and you don't use your hammer yet. And then if we don't find anything, we go to the hammer. We use our reflex hammer, and then we try to test for percussion myotonia. And sometimes we with the reflect hammer, we tap the thinner eminence of the hand, and we can see that you tap, there is a contraction, and then the thumb goes up and then takes a while to go down again. It is a delay in the relaxation of the thinner eminence muscles. Or sometimes in the posterior aspect of the forearm, if we tap the extensor digitorum communis muscle. Again, so, there is a contraction of that muscle, the fingers go up and then take a while to go down. It is also a perfusion myotonia of the extensor digitorum communis muscle. Sometimes people do it even in the tongue. I don't do that because could be very painful. But you can, you know, use a tongue depressor and put it in the tongue, and you tap the tongue depressor and sometimes there is contraction of the tongue, which can be very painful. I don't do it. So- but this is the perfusion myotonia, that can give you also a clue. Dr Albin: That's fantastic. I think this is one of the most memorable things that I saw in pediatric neurology. I remember very distinctly a kid coming in, and then us also examining the mother and having that delayed relaxation. And just one of those really great neurologic exams, those little findings to tuck away to really make a diagnosis, recognizing that not all patients with muscular dystrophy or myotonic dystrophy will have that finding. But so beautiful. And I think that's a really great explanation. And I will also direct our listeners, if you are a Continuum subscriber, she has some really wonderful videos in her article from the EMG sounds of this, which is another layer of being able to appreciate the physical exam finding. One of the things that I was really struck by, and that you've already mentioned, is that there is this really incredible spectrum of disease. That some of the myotonic dystrophy patients may barely have any skeletal involvement, and the ones with congenital myotonic dystrophy may have significant mortality even within the first year of life. Given how many subtypes of this disease there are in that varied presentation, let's just walk through sort of starting with congenital myotonic dystrophy. What are some of the clues to that diagnosis? Dr Gonzalez-Perez: Yes. So, you know, these babies with congenital myotonic dystrophy, actually when they are born, the phenotype is what we call a floppy baby. Floppy baby syndrome right? So, they are very weak. There is generalized weakness, including the swallowing muscles and the respiratory muscles. So sometimes, you know, these patients, these babies have to be intubated---to have a feeling tube, right---to survive. So, that's why the mortality can be so high during the first year of life, because obviously swallowing and breathing is affected because the muscle, those muscles, are also affected. So, one of the clues, actually- you know, sometimes these patients may have, like, a tented mouth, which could be a sign of congenital myotonic dystrophy. The differential diagnosis for a floppy baby syndrome is very broad and can be caused by central nervous system problems or peripheral nervous system problems. So, it's very broad, but maybe the tented mouth can be a clue to suspect the congenital myotonic dystrophy type one. And I will say that also, examine the mom. Because sometimes the mom is not diagnosed with myotonic dystrophy, and as simple as going into the mom who is an adult and can have already the myotonia that we talked about before and maybe, you know, try to do, like, a grip myotonia, eyelid myotonia, or use your reflex hammer and tap a few muscles, and then can give you the diagnosis of potential congenital myotonic dystrophy in the baby. And I have to say that there is no newborn screening for myotonic dystrophy type one yet. Maybe in the future it's going to be, but not at this time. So, I'm pretty sure that pediatricians probably rule out other things before unless there is distinctive mouth or unless the mom is affected. Dr Albin: Great pearls about how to take it to the bedside and try to look for that hereditary nature of this. Let's move up a little bit in sort of the childhood and adolescent onset. What are some of the clues that you're seeing for those children who come to presentation a bit later in life, but still probably more likely to be seen in pediatric clinic? Dr Gonzalez-Perez: Yes. So, the childhood and adolescent onset in myotonic dystrophy type one, it is interesting because the skeletal muscle may not be the organ that is more affected or the organ that impacts the life of the patient and the family of the patient. So, it's- the phenotype is predominantly focused on behavioral and intellectual disabilities. They may develop at some point myotonia, and they may develop also muscle weakness. But for the most part they are ambulatory. They eat by themselves, they breathe okay, and there is not too much problem with the skeletal muscle, but mostly with behavioral problems such as, for example, ADHD or intellectual disability. So, they may need some help in school and things like that. So, it is more, I will say, a central nervous system phenotype at this age. Dr Albin: Yeah, I love that that this is- to me, this was part of the complexity of this was that, while we call it myotonic dystrophy, the muscle part of this disease really may not be the main issue for the patients and their families. And that we're actually looking for something that involves the central nervous system, endocrine system, GI system. And knowing that maybe the muscle is not the main problem here, why is it so important that these patients actually get the correct diagnosis? Dr Gonzalez-Perez: Exactly. So, it is very important. And I always think about the heart. You know, the heart can be affected in the sense like the rhythm of the heart can be abnormal. And sometimes, you know, the patient doesn't have symptoms. But it's important to detect this because, you know, an abnormal rhythm in the heart can cause sudden death. So that's why it's so important. The diagnosis of this muscular dystrophy at this time, and of course in the future when we have a treatment, right, will be very important also to have the diagnosis, the earlier is the better, because probably the treatment is going to be more effective in the earlier stages than in the later stages. But I will say that right now making sure that the heart is in a good shape and the patient has a cardiologist on board if they have myotonic dystrophy. And also, you know, there are consensus-based care recommendations for myotonic dystrophy type one for the pediatric population and the adult population, and also for myotonic dystrophy type two for the adult population, that are published. And I also included in the chapter because they are very important to look for things that maybe the patient it doesn't complain about, but it's important to look for them in the case that we can prevent some future complications. Dr Albin: Absolutely. I really love that. This is a systemic disease that has multiple manifestations, and while the skeletal muscle involvement may or may not be causing problems, we really do have to get the right diagnosis, particularly as it impacts the heart and preventing fatal cardiac arrhythmias. Up to this point, we've mostly been talking about type one myotonic dystrophy. What sets type two apart? Dr Gonzalez-Perez: Yes. So, type two is, I think, even more under-recognized, probably because the phenotype is even more variable than type one and can be much milder in some sense. We are not aware of, you know, like, there are some pediatric cases that have been reported, but for the most part it's an adult muscular dystrophy, type two. So, we diagnose these muscular dystrophies usually in the forties, fifties. The thing is, like, sometimes patients actually may only have muscle pain. And not even muscle weakness. And so… and actually some of these patients may receive a diagnosis of fibromyalgia, for example, just because of the muscle pain. And it is more difficult to obtain myotonia on exam, actually. I think there is a delay in diagnosis in this population, and also the multisystem involvement, which is present but maybe even more variable than that in type one. And we have less patients, so we understand less the phenotype of these patients. But for the most part it is, I think, more under-recognized in the type one. Dr Albin: Fascinating. So again, could have pretty mild skeletal involvement and may just have cramps and muscle pain. So, you have to be really sort of mindful of keeping this on the differential for people with multiple areas of pain in the muscles. When is this suspected? Are you usually sending genetic tests to confirm? How do we get to the diagnosis? Dr Gonzalez-Perez: In the history, in the past medical history, you have probably- sometimes you have the clue. For example, a patient with muscle pain, imagine like for example a forty-eight-year-old male with muscle pain comes to the clinic, and then he tells you that he had cataract surgery at the age of twenty. And then you see a CK that is a little bit more elevated than usual. And then at that time I will go for genetic testing right away, for my myotonic dystrophy type two. Because of the muscle pain is so characteristic of myotonic dystrophy type two, and the multiorgan involvement sometimes includes a very early cataracts, the same as in type one. But the muscle pain is much more typical for type two than for type one. So, that's why I will go, in this specific scenario to type two. If I still think that my alternative dystrophic type two is a possibility, although I'm not totally convinced if it is or not, I usually go for EMG. I mean, if you don't see myotonia at the side, maybe with the EMG and the needle in the muscle, you can see this electrical myotonia that I have some videos in the chapter to see if there is this motorcycle sound of the electrical discharges from the muscle that are consistent with- they can be seen in myotonic dystrophy type two. They are not as specific, but can be seen in myotonic dystrophy type two. So if I have a patient with muscle pain and then I see this electrical myotonia on EMG, so then I will go then next to a genetic testing for myotonic dystrophy type two. Sometimes if there are some family history, it gives you also clues about the possibility of myotonic dystrophy in general, but also myotonic dystrophy type two. Myotonic dystrophy type two, usually the muscle weakness, when it is present, it's more proximal. While in myotonic dystrophy type one it's more distal. So, this also, you know, helps you to differentiate. But specifically in this myotonic dystrophy area, I think the past medical history helps you a lot and the family history helps you too. If you see an autosomal dominant inheritance of muscle or other organ problems, you suspect this type of muscular dystrophy. And I have low threshold to test for this if it is possible because, as we mentioned before, knowing what the patient has helps a lot in their care. Dr Albin: Absolutely. I love that. Spoken like a true neurologist, using the history, the physical, thinking about the family history, using EMG as an extension of our physical to really find and clinch that diagnosis, and then using genetic tests as a confirmation to get to the right answer. I love the mention of early-onset cataract. Are there any other things that pop into your mind or when you're reading the chart and you look at the medical history that, like cataracts, stand out to you as, this really clues me into myotonic dystrophy? Dr Gonzalez-Perez: Yes. So, for example, a pacemaker at early age---in their thirties, in their forties---; a family history of sudden death---for example, having a surgery for whatever reason, having a surgery like for example, surgery for appendicitis and have complications from general anesthesia, like a delay in the awakening from the general anesthesia because patients with melatonin dystrophy are very sensitive to anesthetics and also any sedative medication. So, that gives me a clue that, you know, patients with melatonin dystrophy can have this type of history. I think that those will be the main ones. Sleep apnea is very common, but we know it's also common in the general population. So, maybe sometimes, actually, we may think too much and it is, you know, normal for the general population, more frequent in the general population. But, yeah. And daytime sleepiness that can be caused by the sleep apnea. But sometimes these patients have profound daytime sleepiness. Like, they really complain about that. You know, I need to nap very often during the day because of this. Those features, I think, increase my suspicion for myotonic dystrophy. Dr Albin: Fantastic. So, in the brief time that we have left, I'd love for you to tell us a little bit about what's on the horizon for treatment for these patients. Dr Gonzalez-Perez: Yes, we have exciting preclinical and clinical trials in myotonic dystrophy type one; not yet in myotonic dystrophy type two. And these trials try to target the genetic defect at the level of the DNA or at the level of RNA. So, we have small molecules in clinical trials. We have also some antisense oligonucleotides in clinical trials. We have some small interfering RNAs in clinical trials. And then the CRISPR, which is another new technology, that is trying, you know, to repair this long function that causes myotonic dystrophy type one. And the important thing is, like, once we know what works for myotonic dystrophy type one, we may have good clues also for myotonic dystrophy type two because they share the common pathogenic mechanism. Dr Albin: Fantastic. So, it sounds like there's some genetic therapy in the pipeline. There is some small molecule treatments that are going to be available. So, really an exciting time. There's going to be a lot of changes coming forward to these patients.

Dr Monteith: This is Dr Teshamae Monteith. Today I'm interviewing Dr Hani Kushlaf about his article on muscle channelopathies and rhabdomyolysis, which appears in the October 2025 Continuum issue on muscle and neuromuscular junction disorders. Hi, Hani. How are you? Dr Kushlaf: Good. How are you doing? Thank you for having me. Dr Monteith: Well, thank you for coming on our podcast. So why don't you introduce yourself? Dr Kushlaf: So, I'm Hani Kushlaf. I'm a professor of Neurology and Pathology in the Department of Neurology and Rehabilitation Medicine at the University of Cincinnati in Cincinnati, Ohio. Dr Monteith: And what got you interested in muscle disorders? Dr Kushlaf: So, this is a long story. At first in residency, I was interested in epilepsy, but the moment I started doing a rotation in neuromuscular, I became enamored with neuromuscular disorders. I remember seeing the first patient in the rotation who had myofibrillar myopathy, and I found out that there is very little known about muscle disease at the time. So, I became very interested and I immediately changed direction as I started doing nerve conduction studies and EMGs and having that procedure base, I just decided that I want to pursue neuromuscular disorders. Dr Monteith: Well, that doesn't sound like a long story. It sounds like love at first sight. Dr Kushlaf: Yes, I think part of it is not very far from neuromuscular disorders and that it does have some electrophysiology involved. But muscle disease and nerve disorders, they need that detailed neurologic examination, which I love in terms of doing the localization exercise. Dr Monteith: Great. So why don't we talk about the objectives of your article? Dr Kushlaf: This article was written to review muscle channelopathies that include myotonic disorders and periodic paralysis, and also rhabdomyolysis, with emphasis on genetic causes of rhabdomyolysis more than acquired causes. Dr Monteith: So, why was this update so important? Dr Kushlaf: I think this area of muscle disorders hasn't seen a lot of progress in recent years, but there are interesting findings that we're learning that spark, hopefully, more research into the area, because we do have significant gaps that are related to understanding pathophysiology of some of these disorders. For example, in patients with periodic paralysis, it's clearly known now that these patients over time develop muscle weakness, and the muscle weakness is unrelated to how many episodes of weakness they have---basically, the episodic paralysis part of the disease. So, this is an important finding that I think we need to look more into it and understand that these disorders actually progress, even though that they may not have episodes of paralysis. In addition, there are genetic therapies that have been introduced into most of neuromuscular medicine at this time, including muscle disorders, while this specific part of muscle diseases has not had that luxury yet. And I'm hoping over time that there will be an introduction of gene therapies for these diseases. Dr Monteith: Great. So, it sounds like there's some clinical advances, then, as well as genetic advances. Now, you also spoke about rhabdomyolysis and that there's newer ways of thinking about that from perhaps when I was in residency. So why don't you update me on these newer approaches? Dr Kushlaf: The rhabdomyolysis… first, the definition of it is changing. We used to use a cut off, a CK of about a thousand, to call it rhabdomyolysis. And very recently it's clear that that level of CK is not sufficient to call it rhabdomyolysis. So, now the level went up in terms of exertion of rhabdomyolysis, up to ten thousand, has to be more than ten thousand. And in patients who haven't had exercise, the level is up to five thousand. So, it's no longer actually one thousand. And that refinement in the definition is important because there are some patients who exercise all the time and they may exercise at an athletic level and they have very high CK's. And those patients should not be labeled as having rhabdomyolysis. Basically, they are doing strenuous physiologic exercise. In addition, not only the definition of rhabdomyolysis is changing, it is our approach to which disorders to consider first and how we should work up patients with rhabdomyolysis. So, acquired rhabdomyolysis remains the most important etiology to be ruled out first. So, I always tell my fellows and residents that, think about acquired rhabdomyolysis first before you think about the genetic disorder. After you rule out the fact that it is not a toxic or metabolic or medication-induced rhabdomyolysis, then think about a genetic etiology. But when you get that consultation from the hospital that the patient has rhabdomyolysis and we want you to figure it out, always look at the medication list and make sure that there isn't anything on it that causes, actually, a rhabdomyolysis. And in many instances, you find out that it's actually a toxic or metabolic etiology for the rhabdomyolysis. And as part of this article, there's also an acronym that's now being used to identify those patients who would benefit from genetic testing. The acronym is called RHABDO. It's as is the word, RHABDO. R refers to Recurrent exertion of rhabdomyolysis. So, it's not just one episode. And the H refers to HyperCKemia, and the hyperCKemia should persist more than eight weeks after the episodes of rhabdomyolysis. And if it is exertional, then the person has not done an unaccustomed exercise. So, they have changed the way that they do exercise and now they are exercising for two hours instead of one hour or they have introduced a new way of exercise into their exercise regimen. Then that should not be considered. It's not considered necessary to test these patients for a genetic cause. Also, the muscle enzyme typically, in genetic causes of rhabdomyolysis, goes more than fifty times above the upper limit of normal, which is more than a thousand. So that has to be taken into account. And then for the D it's Drugs and medications. This has to be ruled out before you say yes, we need to find the genetic cause of rhabdomyolysis. And then the O, it's basically family history. If you find that there is other family members who are affected or they have a high CK, then of course that would point you toward doing genetic testing. Dr Monteith: Great. So, it sounds like there's some advances there in how we approach these patients. In what way is this practice changing? You mentioned, you know, really important to rule out these potentially reversible causes first. Dr Kushlaf: Yeah. So, once you identify the theology, it becomes easier to manage the patient. So, if it is a statin-induced rhabdomyolysis, you know that you want to stop the statin and you are not going to have this problem again. So, that's quite important. The statins, of course, will have to not be reintroduced in the future for that specific patient who developed statin-induced rhabdomyolysis. But for the genetic causes of rhabdomyolysis, if you go down the path of genetic rhabdomyolysis, of course we have no cures for these disorders. We may have treatments. One of the conditions that I have alluded to as one of the case presentations in the article is a patient who has riboflavin responsive multiple acid CoA dehydrogenase deficiency, and I wanted to highlight this disorder because it's a disorder not to be missed. It does have a treatment, which is riboflavin, and that comes from the name riboflavin-responsive. So that's why I put there in the article as part of the manuscript. However, some of these disorders, once you find the genetic etiology, there may be a way of preventing it in the future generation. Family planning, reproductive medicine technologies, can help in this instance and prevent this disease from occurring in the future generations. Dr Monteith: So, why don't we move on to episodic skeletal disorders? What is your general approach for these types of diseases? Dr Kushlaf: Muscle channelopathies, skeletal muscle channelopathies, are ultra-rare disorders. And part of the issue is not giving them a high index of suspicion in the diagnostic process. So, these patients typically come to us in clinics with very vague symptoms, and they may have lived with these symptoms for a very long time. So, they may have muscle pain, they may have fatigue, they may have muscle stiffness. Even though in most instances they do not tell you that they have muscle stiffness, they will tell you that when I wake up in the morning, I feel like I walk like a robot. My legs feel rigid, something like that. The word stiffness is not usually in the vocabulary of patients. When they come to see you and you examine them and you find out that the muscle strength is normal, you may not think much about the myotonic disorder. And that's where the issue is. You always have to keep these disorders in your differential diagnosis. So, you elicit for myotonia and for paramyotonia on examination, look at the muscle size, see if there is any muscle hypertrophy that happens in fluoride channelopathies, and that will typically guide you toward the diagnosis. And also ask about whether their symptoms get worse in a cold environment. So, sometimes they tell you they don't like winter because during winter everything is not doing well. They may report that they even feel like they cannot move their face because of facial stiffness in wintertime, especially in states where it snows outside and patients will be walking outside. So, these are things, typically, that give you clues about the diagnosis. But in patients who are affected minimally with the disease, sometimes you do not catch them, really, till they come to the EMG lab because of another reason. If they develop a neck pain and someone thinks that they may have a cervical radiculopathy and they want to do an EMG on them, or if they develop carpal tunnel symptoms, they send them to the EMG lab for carpal tunnel. And the moment we see them in the EMG lab, we start doing the needle examination and we find out that there is myotonic discharges in every muscle that we stick with the needle. And we're like, well, this person must have a myotonic disorder. And you ask them more about their symptoms. They may have symptoms, but they will tell you that they have ignored them for too long because it's something that they live with throughout their lives since childhood. They thought this is what is normal for them and this is what normal people might have. They may have aches and pains here and there and that is normal. So, these are clues, typically, for the diagnosis. Once you find the myotonia, your next bet to identify the exact genetic abnormalities to do genetic testing. And nowadays I think the field has benefited from the availability of free genetic testing so we can find out which channel is affected and then move on toward freezing that disorder. Dr Monteith: So, you spoke about nondystrophic myotonia. What are some bedside tips to try and really get at the diagnosis? Dr Kushlaf: So as I said, first is, look at the muscle build of the patient. So, these disorders, chloride channelopathies---so, the autosomal dominant and autosomal recessive chloride channelopathies---can cause muscle hypertrophy. So, these patients can have an athletic appearance even though when you ask them, do you exercise? I don't exercise at all. Do you lift weights? I don't lift weights at all. And they look like bodybuilders, so that's something to think about. Also eliciting the myotonia and typically we elicit the myotonia by using, of course, the reflex hammer. You can either tap on the phenol eminence and notice the myotonia in the thumb as it moves inward and stays in that position for some time. Depending on the severity of the myotonia, you can tap on the extensor digitorum in the forearm and notice the middle finger as it gets up and gets stuck for some time before it goes down. You can also ask patients to squeeze your fingers and then release quickly. Squeeze forcefully, of course, and find out how long does it take them to release their fingers, and that way you can identify the myotonia. Also, you may need to repeat the elicitation of myotonia several times because it can be not myotonia but paramyotonia, which is the opposite of myotonia. It's basically worsening of the myotonia as you keep doing the eliciting activity. So, the more they squeeze your fingers, the more difficult it is for them to improve. While the warm up phenomenon, which is the opposite of paradoxical myotonia, is, for them, as they repeat squeezing, they are able to do it better and better. They would be able to release more quickly with each attempt. In some patients, you can also ask them to close their eyes if they have facial myotonia, to close their eyes forcefully and see how quickly does it take for them to open their eyes. You may see that they do not open their eyes quickly. Or if you repeat in patients with paramyotonia, if you ask them to close and open, close and open, close and open, there will come a point where they really cannot open their eyes anymore, and that tells you there is paramyotonia. Of course, if you find paramyotonia, then you know that this is a sodium channel abnormality, that the genetic testing would just confirm that. Dr Monteith: And what about for periodic paralysis? Is there anything new in the field? Dr Kushlaf: Periodic paralysis… if I can say one thing about periodic paralysis, it's to talk about Andersen Tawil syndrome. It's an ultra-rare disorder also, but the episodes of paralysis that happens in patients with Andersen Tawil syndrome, they occur either with hypokalemia, so it can be hypokalemic---like, exactly hypokalemic periodic paralysis---or with hyperkalemia. So, it's hyperkalemic periodic paralysis. It doesn't really matter whether it's hyperkalemic or hypokalemic. These patients they typically have dysmorphic features. And the most common dysmorphic feature, and I chose a picture for the article, is a patient who has a small mandible. That is the most common dysmorphic feature. There are other dysmorphic features which include short stature, hypertelorism---which is the distance between eyes, the eyes become widened. Also, scoliosis and low-set ears. So, the ears are lower than the level of the eyes. So, these are dysmorphic features one can look for, but they do not exist in every patient with Andersen Tawil syndrome. The problem with Andersen Tawil syndrome is that these patients, as opposed to hyperkalemic and hypokalemic periodic paralysis, they have cardiac involvement. And the cardiac involvement can be deadly. So, it's very important that these patients are identified quickly. And anyone who has episodic weakness should have an EKG and should have halter monitoring to recognize if there are any arrhythmias or EKG abnormalities. So, one can identify anything that needs to be corrected from the cardiac standpoint. I think that is the most important point about periodic paralysis. Overall, these disorders… I mean, they are disabling and they can have huge effect on patient's life in terms of productivity and employment. And the diagnosis can be very difficult, especially that we do not know all the genes that are associated with periodic paralysis. Right now, the genetic testing that's available to us includes five genes that are associated with periodic paralysis. But I think we need to know more. There's a proportion of patients who do not have an identifiable abnormality at this time. So, I think as time goes on, we'll recognize more causes for periodic paralysis. Dr Monteith: I'm just reading your really great article, and it sounds like there's a lot of variability in presentation from I'm not feeling that well or I'm not feeling my best for mild disease, and then very severe disease where the whole body can be weak without alteration in consciousness. Dr Kushlaf: That's correct. So, my patients tell me that you never know when you're going to develop episodes of weakness. And sometimes they can recognize the precipitant, sometimes they cannot. Stress, sometimes, is a precipitant. At times, they really cannot tell what happened. And the weakness can be affecting one limb or more than one limb. It can be isolated to an arm or isolated to one leg. And that is the issue with the diagnosis, is that for those who do not suspect periodic paralysis, they are labeled as a functional neurologic disorder and they do not get the care that they need. I'm hoping that this article will shed a light on how to think about these disorders and how to diagnose them because treating them can have a significant impact on patient's life. Dr Monteith: How useful are these laboratory tests? Dr Kushlaf: So, in any patients where I suspect periodic paralysis, I would always do thyroid function testing to rule out hyperthyroidism because it can cause episodes of paralysis similar to hyperkalemic and hypokalemic paralysis. And I also do EKG and halter monitoring to make sure that I'm not missing the cardiac manifestations of Andersen Tawil syndrome. On top of that, then I would do genetic testing. And the genetic testing, as I said, at this time includes five genes. So, we will recognize any genetic abnormality that comes on that genetic testing. And if it is negative and I still have a high suspicion for the disease, I will do a long exercise test. The long exercise testing is, we record from a muscle in the hand---it's called the productive digit minimi---and stimulate the unknown nerve. We record, typically, baseline responses and then exercise the muscle for five minutes and keep recording after five minutes of exercise for up to forty minutes after. We're looking for a change in the amplitude of the motor response that typically happens over time. Dr Monteith: Great. Well, thank you so much for being on our podcast. Dr Kushlaf: I appreciate it.

Inflammatory myopathies are a large group of disorders associated with an inflammatory response targeting skeletal muscle. Treatment hinges on the use of evolving immunotherapies and diagnostic tools to quickly identify inflammatory myopathy, initiate appropriate therapy, and exclude underlying malignancy or infection of other organs.

Dr Grouse: This is Dr Katie Grouse. Today I'm interviewing Dr Anthony Amato about his article on idiopathic inflammatory myopathies, which he wrote with Dr Kian Salajegheh. This article appears in the October 2025 Continuum issue on muscle and neuromuscular junction disorders. Welcome to the podcast, and please introduce yourself to our audience. Dr Amato: Thank you. And I am Tony Amato. I'm in Boston at Mass General Brigham. Dr Grouse: It is a distinct pleasure to have you here with us today, and I'm really excited to talk with you about your article. I thought it was a fantastic overview of the subject. And I'd like to start by asking what you hope will be the key takeaway for those who are reading this article. Dr Amato: I think it's kind of basic: how to make a diagnosis, describe about the inflammatory myopathy as approach to, again, diagnosis, and then a little bit on pathogenesis, which… and kind of leading to the treatments, and hopefully we'll have more treatments based on the distinct pathogenesis in the future. Dr Grouse: Can you give a brief overview of the categories of inflammatory myopathies you reviewed in your article? Dr Amato: So, I mean, the major inflammatory myopathies, radiopathic inflammatory myopathies, are dermatomyositis, antisynthetase syndrome, immune-mediated necrotizing myopathy, inclusion body myositis, and polymyositis. Now, that's been a big change, as you know. I mean it used to be, you know, we all started off it was dermato or poly. But I've kind of made a name for myself- a bad name for myself in the early 2000s saying, I'm not sure there's much of a thing called polymyositis. I think it's a hodgepodge and it's not distinct. And that's come to be, now most of those cases are- now we find out having antisynthetase syndrome or necrotizing myositis or IBM. Dr Grouse: Could you walk us through your diagnostic approach with a patient in your clinic presenting with symptoms that are suspicious for inflammatory myopathy? Dr Amato: So, you want to really make sure that they have inflammatory myopathy as opposed to some other kind of myopathy, a muscular dystrophy, for example. Taking family history first is going to be important, clueing in are they really weak or what they're complaining of is fatigue or muscle pain? Are they feel weak but what they really are complaining of is stiffness and rigidity from parkinsonism, or they have a sensory ataxia so they can't modulate? I want to know about other organ system involvement. Do they have a rash? Do they have joint swelling and pain that you might see with arthritis? Do they have shortness of breath that you might see with interstitial lung disease or ventilatory muscle weakness? Or do they have a cardiomyopathy? What kind of weakness do they have? Is it proximal weakness in the arms or legs? Getting out of a chair, climbing stairs. Do they have problems lifting their arms over their head---so, proximal weakness---or do they have more problems with grip, finger flexion, holding a pen, tripping? Do they have swallowing problems? Do they have ocular problems? So that's the big history on the exam. Again, I'm looking for pattern of involvement. So, on my exam, is there atrophy or weakness in muscles---you know, fasciculations---which would take it out of the motor? Is it mainly proximal? Is it distal? Again, is there ocular bulbar involvement? Is it symmetric, particularly in, like, the IBM? Most of the other inflammatory myopathies are going to be mainly and proximal and mainly symmetric. IBM is different, and that the- at least in the hands it's more distal, and it's finger flexors. So, you're looking at flexing the tips of the fingers, you're looking at the forearms, best looked at in a semipronated position to see if it's atrophied. And that leads you to an IBM if you see that. So that's the main things on exam. Dr Grouse: That's a really helpful overview. I was wondering, in earlier training days, the convention was you- once you've suspected myopathy, you get your CK, you get your EMG, then that may give you the information you need for your diagnosis. It seems that things have been turned a little on their head. We're often skipping those things to go straight to the antibody testing. When should we be going for the myositis-specific antibodies before considering other things like EMG or muscle biopsy? Dr Amato: I would always get a CK first. You know, in somebody who's weak. You know, the EMG, I don't need an EMG if the CK is two or three thousand. I mean, EMG is- localize it to, is it muscle, nerve, neuromuscular junction. If it's very elevated CK, it really doesn't help me there.  Sometimes if I have myotonic discharges or something that might make me think of a myotonic dystrophy or something else like that. But you can see that with the inflammatory myopathy. So, if I'm pretty sure of a myositis, I don't always do an EMG, or- unless I really need it to help guide what muscle biopsies I do. if I'm suspicious then on my exam and I see the CK---or they come to me already with the CK, which often happens, and it's very elevated---that's when I'll do the myositis-specific antibody panels if I'm really thinking that. And the important thing to know from that is, you have antibodies for dermatomyositis and antisynthetase that are on the panel that are available, and even signal recognition particle, which is a necrotizing myositis. But what's not on the panel is HMGCR antibodies, which is important because that's 70% of the necrotizing myocidites are HMGCR, and then the IBM antibody and T5-C1A is not on that. So, you need to order those separately. If somebody doesn't know, they order a myositis-specific antibody and think that it's all-inclusive, but it doesn't have IBM or the HMGCR antibody. And the other test that I sometimes will do is a skeletal-muscle MRI to help in the evaluation. Sometimes, not all the time, but I'm not sure it's a dystrophy, is it a myositis when I see a lot of STIR signal, which is edema. And you can still see STIR signal in a dystrophy and toxic. But sometimes I'll do it depending on whether I need a biopsy or not. Dr Grouse: What is the benefit of an open biopsy versus a needle biopsy, and when should we be considering using one over the other? Dr Amato: So, it really is not our decision. It's the pass lab. So, it's the technicians and the pathologists who read the biopsies need to be able to process a needle biopsy, which might be much smaller. Needle biopsies show to be fairly accurate in a lot of the hereditary disorders where you might just look for central nuclear core, and they might be- so, mainly in kids, but in the inflammatory myopathies, it's really patchy. So, if I'm thinking of an inflammatory, I like an open biopsy. I think it's hit and miss. And so, I like open biopsies for the adults that I'm thinking of inflammatory. Dr Grouse: Do you have any other tips or tricks in the diagnosis of inflammatory myopathies that you could share with our listeners? Dr Amato: I would say first, in terms of what muscle to biopsy, you're not doing them yourself, but you're referring to a surgeon. You have to tell them what to do with the biopsy. And you want to pick a muscle that's about an MRC grade 4 because if it's a normal muscle, the muscle strength, the biopsy, is likely to be normal. If it's less than a 4, you might just have end-stage muscle. And saying you can't tell end-stage muscle from a bad myositis, from a dystrophy, from a severe end-stage neurogenic. If I don't have a muscle that I would typically biopsy that's an MRC grade 4---for example, somebody with an early weakness and they're only weak, say, in their in their hip girdle. So hip flexors, abductors, extensors, and we're usually not biopsying the iliopsoas or the gluteal muscles. Then what do you pick? That's when I like to do an EMG on one side of the body and look at proximal and distal muscles and select one that's irritable, you know, some fibs and positive sharp waves that I might biopsy. And then maybe consider doing a skeletal muscle MRI to go from muscle that's abnormal, that has a lot of edema in it, to increase the yield. Dr Grouse: That's really helpful. And then, I think, jumping from that, what are pitfalls that you've seen neurologists fall into in this diagnosis or other challenging aspects of the diagnosis that you could review with us? Dr Amato: Some of the things that we see are hard to pick up. It might be hard to pick up a rim vacuole. They're very rare, too. And so, you might miss it, particularly if you don't see a lot. Sometimes, like looking at the dermato and that's the, on the exam question, perifascicular atrophy, but that's a late stage, usually. And so, if you're really attuned and you're a good clinician, you make that diagnosis really quick. You do a biopsy, you might not see that paraphysical atrophy. So, they don't know that in a necrotizing myopathy, the pathologists often think of what they see in a toxic myopathy or a metabolic where there's a lot of necrotic fibers. But in most of the autoimmune necrotizing, it's not. It's actually what you see is more regenerating fibers, a few necrotic fibers. It's because it's usually been smoldering along for a while, and so you have many more regenerating fibers than ones that are actively, and that can fool a lot of people. So, that's a pitfall from that end of things. Some of these myositis specific antibodies aren't specific and at a low titer, particularly if you have more than one antibody being positive, that would be a red flag that it could be false. That's another pitfall. I think a lot of people don't, when they're examining people, really look at the finger flexors and stuff. And again, if I have somebody over the age of fifty, the most common muscle disease is IBM. Number two is IBM, number three is IBM. If you don't- and you have to think about that, and you need to examine the distal finger flexors because it doesn't get better with immunotherapy. You don't want to put people at the risk of immunotherapy when they're not going to get better. I talked a lot about the biopsies, and biopsy, biopsy, biopsy. But you know, sometimes you can make the diagnosis without a biopsy. So, if somebody's like a classic dermato rash and they have a dermato antibody, do they need a biopsy? No. If they have, you know, CKs of ten thousand proximal weakness, they're on a statin and they have HMGCR antibody, do they need us have a biopsy to confirm? Probably not. Dr Grouse: Those are some really great pearls that you've shared with us, and I think will be very helpful to many of our listeners. Now, you mentioned earlier about the diminishing category of polymyositis as other types of myosidites have been discovered and better described. Do you think that is the most controversial aspect of this field currently, or are there other controversial areas or areas of ongoing debate that exist? Dr Amato: It was very controversial twenty years ago, or maybe ten years ago. So, the rheumatology guidelines, they're the ones that are often saying, oh yeah, we were right. Polymyositis, it's just hodgepodge, and it's ever-shrinking. So that's not so controversial anymore. I mean, the controversies that we have, what's the pathogenesis of dermato? It's still a little debated, some- the old theory was that it was a complement-mediated microangiopathy and the damage was caused by ischemia. That's probably not the case. It looks more and more like it's a type 1 interferonopathy, and that's toxic to the vessels in the muscle. There's still a little bit of a debate about that or, you know, you have complement might be on it, but how much that might be damaging, or it's just a secondary phenomenon. I think in the antisynthetase things, I think there's some interesting things also with that these antibodies. We used to think of that they're just diagnostic biomarkers. But there's some recent studies suggesting that these antibodies which are directed against intracellular targets, which is interesting and applies to other autoimmune diseases and that are in the brain too. And we would think that, oh, if it's a intracellular target, it it's secondary. But there's suggestion now that- again, it did demonstrate that the antibodies actually get into muscle fibers. And they bind to these targets. So maybe they're just not epiphenomenon, but they might be binding to a target and causing pathology. And that's what there's some preliminary studies that are impressed, I will say, that have antibodies, anti-HMGCR, that actually go into the cell and they inhibit the enzyme. And that might be causing the pathology. And so that's interesting. And then IBM is a big field. Is this a primary autoimmune disease that has these other kinds of degenerative features like REM vacuoles, or is it a primary degenerative that has secondary inflammation, or is it a combination of both? So, that's probably the biggest controversy these days. It is probably with IBM. What the heck is causing it? Dr Grouse: Sounds like a lot that we still have to understand about these diseases. This does lead me to wonder, though, have some of these new discoveries and ideas led to or will lead to any new breakthroughs, either in diagnostics or in therapeutics? Dr Amato: So, certainly in therapeutics. So, the discovery of dermato being an interferonopathy, probably a beta-interferonopathy, has led to development of monoclonal antibodies that target interferon, and there's trials underway. And in phase 2 studies, I can tell you from talking to colleagues that participate just melted away the rash of dermato. So, I think that's going to be a very, very good drug in the future for dermato. There's others, like JAK. JAK inhibitors work on that interferon pathway too. So, I think we'll be going towards, like, less broad-spectrum steroids, IVIG, to going, let's go to the target. Certainly, in dermato, I mean, IBM, we don't know. There is an inflammatory cell that we see in IBM that has a receptor, KCRRN receptor, and there's a monoclonal antibody that targets that in IBM, and that's a phase 3 trial right now. Hopefully that study should be ending in December, and so early next year we'll have results about that. The fact that these antibodies might be pathogenic of themselves is other ways to get rid of the antibodies. So, getting rid of plasma cells and B cells, and FCRN receptors which have been approved or antagonists that are approved for myasthenia. Now CIDP might work in some of the inflammatory myopathies where we think the antibodies might be pathogenic. So, FCRN receptor antagonist and they're in trial now as well. And there's CAR-T therapies to knock out the antibody-producing lymphocytes and plasma cell. So, I think we're going to move into the field of individualized therapies as we find the distinct pathogenesis of these disorders. Dr Grouse: That's really exciting to hear and I can't wait to see what's coming down the pipeline as more of these discoveries are made and the clinical trials advance. It has been such a pleasure. I've learned so much. So much is packed into the article. So again, I can't stress enough, please take the time to check out this article. I think you'll learn a lot, and it'll really help you fine-tune your diagnostic pathway in relation to myopathies. Dr Amato: Oh, my pleasure. Thank you. Anybody has questions, please feel free to send me an email. Dr Grouse: We may just take you up on that.

Dr Berkowitz: This is Dr Aaron Berkowitz, and today I'm interviewing Dr Elie Naddaf about his article on inclusion body myositis, which appears in the October 2025 Continuum issue on muscle and neuromuscular junction disorders. Welcome to the podcast, Dr Naddaf, and would you please introduce yourself to our audience? Dr Naddaf: Thank you for having me. I am Elie Naddaf, a neuromuscular neurologist at Mayo Clinic in Rochester, Minnesota, and one of my main focus research-wise is about inclusion body myositis. Dr Berkowitz: Fantastic. Well, this is a great article on inclusion body myositis, or IBM, as we may refer to it today. It has a lot of clinically practical tips for examining patients at the bedside and a lot of important updates for us on how to diagnose this condition. So, I encourage our listeners to check out the article, and I look forward to discussing some of the key aspects here and learning from your expertise. First, tell us about the classic presentation of IBM, when the disease is pretty easy to recognize at the bedside based on the history and exam. Dr Naddaf: Luckily, IBM is one of those diseases that has a very particular pattern of weakness that makes it easier to diagnose. However, in real life it can be very challenging for several reasons, which we will cover in this podcast and in the article. However, a typical presentation of IBM is that of an older patient, more likely to be a male---twice more likely to be a male---,presenting with slowly progressive weakness over a couple years or so. And the weakness predominantly affects the deep finger flexors in the hand. So, they most commonly present with hand grip weakness, or the quadriceps muscle presenting with some lower limb weakness. However, some patients can present with one or the other, not necessarily with both at the same time. It is usually a painless disease,, and because of the lingering course, patients tend to present within two to three years from their symptom onset. So, with that, on examination, if the patient is presenting with the hand weakness, they would demonstrate weakness in the deep finger flexors, which are the muscles that we use to flex the distal intralaryngeal joints. This weakness is often asymmetric and can be in only one hand; and also, even within the same hand, you can have a variable severity from one finger to the other. And that's one reason, although it sounds a classic phenotype, if you can imagine a patient just presenting with hand weakness, a lot of other things come to mind, whether it's a compressive neuropathy or whether it's a radiculopathy or motor neuron disease. Similarly, in the leg, the quadriceps is a big and strong muscle. So, it's often that patients' symptoms originally or in the beginning get dismissed because the physician did not demonstrate any weakness on manual motor testing. Because it's a strong muscle, it needs to lose a certain amount of strength to be able to demonstrate that weakness by just pushing against the patient trying to extend their knee from about a 90 degree or so. That's why another way in those cases would be to examine them more functionally whether they're kneeling or squatting. It is usually a pure motor disease, although patients can commonly have a peripheral neuropathy. But typically, on exam, you mainly see muscle weakness. Dr Berkowitz: Perfect. So, if we see a patient who's an older man with progressive painless weakness of the finger flexors, quadriceps, this is sort of the classic presentation where we would consider IBM. But you mentioned in your article that some patients can present somewhat atypically when we might not immediately think of this diagnosis. What are some of the atypical presentations we should be aware of that should lead us to think about IBM as a possible etiology for the patient's pattern of weakness? Dr Naddaf: So, IBM indeed can present in any muscle group. That's why about 14% of patients may have the weakness onset beyond the finger flexors or knee extensions. And there are very particular phenotypes that stand out. Especially the most common in that scenario would be patients presenting with pure difficulty swallowing, isolated dysphasia that can sometimes precede the limb weakness by several years, and that's especially common in females. Other phenotypes including just a proximal weakness, like a limb-girdle weakness; an axial weakness, for example, head drop or camptocormia or a foot drop. And because it's an asymmetric disease, you can see the challenge there---if someone just presenting with a foot drop on one side, that it could be challenging to just think of IBM. So, those are the main phenotype. One particular phenotype that is super interesting is, patients present with severe facial weakness as if they have severe bilateral Bell's palsy. And that's the, usually, the most common first misdiagnosis. And all these patients reported so far in the literature are only females. This has not been reported in any male patients. So yes, the finger flexor quadriceps weakness is the most common typical presentation. However, IBM can present, technically, in any other muscle in the body. Dr Berkowitz: Great. Well that's very helpful information that especially comes from experts like you who see a lot of these patients and are able to make these diagnoses of these rare phenotypes. Whereas many of us general neurologists, like myself, might think of IBM only with finger flexor weakness and quadriceps weakness, perhaps with some foot drop dysphagia associated. Sounds like this is a diagnosis to consider in atypical presentations or atypical presentations of myopathy that aren't fitting other phenotypes or aren't yielding diagnostic results for other phenotypes. And you have in your article a very helpful table that goes through some of the common sites of weakness in IBM and the differential diagnosis for myopathies and other conditions to consider in patients who have the classic and less typical presenting features. So, let's say that we see a patient with clinical features suggestive of IBM. How do we go about confirming the diagnosis? What are the main diagnostic tests we would use to try to make a firm diagnosis here? Dr Naddaf: So, the gold standard so far for diagnosis for inclusion body myositis, as it is an acquired disease, has been a muscle biopsy. So, muscle biopsy is the probably most important tool in the diagnostic approach to IBM. Even in patients with a classical phenotype, that all like in any other test, it depends on your pretest probability and how sure you are the patient has IBM. But even with the classic phenotype, it is characteristic of IBM, but not pathognomic of IBM. Because if we see a high number of patients with similar phenotypes, we will run into a lot of other disorder that present similarly. And some patients---especially for instance, with myotonic dystrophies, specially type two---may be very difficult to distinguish from IBM, especially those that present in adulthood that they don't have the classic picture of a myotonic dystrophy patient you would think of. And some of them may not even have percussion myotonia. Because of that, the biopsy is very important to confirm your diagnosis in that regard. And on the biopsy, you want to see evidence of inflammation, basically, and the mesial inflammation, without going into a lot of details, to set it apart from those genetic ones. But in IBM it's not a pure inflammatory disease. There are other features on the biopsy that are very particular to IBM, two main other things we need to find. One is that of the accumulation of autophagic vacuole and protein aggregates and that of mitochondrial dysfunction. So, the other test for patients, presenting with weakness---again that depends on your clinical suspicion---would be first to establish that the underlying process is a myopathy; and hence, the EMG. And also, that's particularly important in patient with symptoms in one limb to differentiate it from compressive neuropathies or from a motor neuron disorder or other. So, the EMG tells you it's a myopathy with fibrillation potential, helps you also choose a muscle for biopsy. So as far as blood tests, the main blood test is that of the cytosolic nucleosidase 1A, or people call them IBM antibody. That's present in about half of the patients with IBM, 50%. Specificity originally reported to be high in the 90s, but in real-life practice with commercial lab it's probably lower in the 70s. There is a growing interest in the use of muscle imaging as well and IBM is one of those diseases similar to the clinical phenotype that has some distinctive pattern on imaging on MRI. But again, like the clinical phenotype, it is helpful, it is characteristic. It's not diagnostic on its own. Other blood tests in IBM include creatine kinase level. As long as you're not seeing creatine kinase in the 10,000 or 20,000, that would be very unusual in IBM and other routine blood tests that are discussed in the article. Dr Berkowitz: Right. That's a very helpful overview of the testing we would consider when we're trying to make this diagnosis that can include, as you mentioned, EMG, muscle MRI, and this five-prime cytosolic nucleosidase 1A antibody. As you said, many of these have variable sensitivity and specificity. We can diagnose a myopathy generally, or muscle inflammation more specifically, using EMG and muscle MRI respectively. It's interesting to hear that that antibody, I know there was a lot of excitement about that originally. Sounds like less sensitive and less specific than one would have hoped. In your article, you discussed sort of how to use some of these tools to try to meet the diagnostic criteria that were updated in 2024 for diagnosing IBM. And correct me if I'm wrong, this is my first time reading about these. I want to make sure I understand that essentially, you always require a biopsy for definitive diagnosis of this disease. Is that right? Dr Naddaf: That's correct. That's because of the issues that you raised with the antibody and because, even with people with the classic phenotype, you still could have other diseases that can mimic IBM that are associated with different complications, comorbidity profiles. For instance, myotonic dystrophy requires very close monitoring of cardiac rhythm, which is usually not affected in IBM. Hence, there is still the need for a biopsy, as we don't have a better test so far. The antibody has its own challenging, but I still find it very helpful in certain situations, and that's also reflected in the new criteria. It's definitely not a standalone diagnostic test. I don't think you can just draw the antibody, if it's positive, tell the patient they have IBM. To me, it's helpful in two ways, at least in my practice. One way is, it makes me think of IBM in situations where I was not considering IBM. In the end IBM is the most common disease in adulthood, so it's not a bad habit to just check the antibodies in any unusual case. Or where inconclusive case, it's just me saying, huh, that could be IBM that I missed. Then I go and try to confirm it. The other scenario that it helps me, there are a lot of cases that remain inconclusive. For instance, you just saw inflammation on biopsy, you have some pattern on MRI. You just need another piece of information to further make the case for the diagnosis. And that's where I find the antibodies helpful. And that's reflected in the new criteria. Dr Berkowitz: I see. So, if you- Yeah, so just to pick up on the antibody here, since I'm sure people be interested in when or whether to send this. You sort of use this in atypical cases where you know it's a myopathy or not. You haven't yet made a diagnosis. And you think, well, if I send this and it's positive, that's not 100% specific, but going to tip me a little more towards thinking this could be an atypical IBM case. But if it's negative, it doesn't sort of tell you either way, since you said it's only about 50% sensitive, right? Am I understanding correctly how you use the antibody? Dr Naddaf: Yes, this is correct. So basically, you don't have to check it if you think it is IBM; that also depends on your style of practice. To me, I think at some stage, with all the progress we're seeing in research in systems biology, so far there's no indication that the antibody predicts severity, and I don't think it does. But there could be at some time down the road that there are different underlying pathways or disease mechanisms that are associated with people that have the antibodies. So, it's more like for the future, it's good to know if the patient is positive or not. Dr Berkowitz: Okay. So, if biopsy is really necessary to make this diagnosis, if you see a classic presentation with an older man, as we've said before, with slowly progressive painless finger flexor weakness and quadriceps weakness, do we even need EMG or muscle MRI or this antibody or do you just go straight to biopsy in those cases when the clinical phenotype looks relatively certain? Do you still think one or more of those tests are helpful in the classic presentation? Or are those EMG, muscle MRI, and the antibody ones used more when you think, this looks sort of like IBM but it's either it's maybe early and it's not sort of fully kind of developed into the classic phenotype or it's very asymmetric, which you can see in IBM, or whether it's sort of has more atypical features or only one of the classic features? How do you use EMG muscle MRI in the antibodies when you know you're going to need biopsy ultimately, if this is the diagnosis you have in mind? Dr Naddaf: That's a great question. And all of the above would be correct depending on the setting you practice in. If I were practicing in a community where I have the privilege to do things step by step, I might approach it a little bit differently. Being at the referral center with many patients coming with a one-stop shop and they need to do everything possible rather than returning, that's also another different practice scenario. But in general, you want the EMG if you're not sure it's a myopathy, especially that these patients are asymmetric and sometimes the findings are in a single limb. So, you would want the EMG when you're not sure it's a myopathy, or also you need a little bit more information on what muscle to biopsy, you could use the EMG. If those questions have already been answered, you don't have to do the EMG. Now regarding the biopsy, if it is the classic phenotype and you think it's going to be a bingo with the biopsy, you might not need to do any antibody or MRI or any further testing. Now with one caveat that the biopsy might not give you the full picture or all the features, then you could go back and do the rest. And that's actually all integrated in the new criteria. So, in the new 2024 revised European Neuromuscular Center diagnostic criteria for IBM, the main differences are the following: now you can use additional test measures to support the diagnosis in addition to the biopsy. So that will probably reduce the need to have a repeated muscle biopsy. Two, you could have an atypical form and still have the diagnosis. You don't have to wait until your finger flexor or knee extensors are involved. And that's very important also, because criteria generally are made for clinical trials where you want to know for sure who you are treating. But at the same time, you don't want to wait till advanced stages of the disease where treatments might not work. Diagnostic criteria are not made to be used in clinical practice, but at the same time they offer a good framework, a good suggestion for people to use in their clinical practice. And just always remember to tailor it to your particular patients that you're seeing. In those criteria, basically, we go by scenario depending on your level of suspicion. There is no possible probable. You either make the diagnosis or you don't make it. And as you said, if you have a classic phenotype patient with deep finger flexor weakness in the upper limb and knee extends her weakness in the lower limb, your pretest probability is very high, and the chances that you're wrong are low. They're not zero, they're low. That's why I was just showing in the mesial inflammation on the biopsy, which would rule out your genetic mimicor. You're pretty confident of the diagnosis. And the other scenarios, then let's say you have only one limb, then you need a little bit more support. And you have an atypical form where the differential is very wide. You want to provide more supportive criteria, and the supportive criteria could be other features in the biopsy, whether it's the CCO negative fibers or derma vacuoles, or you could use MRI and antibodies if they're available to you. In many countries, these are still not available, but if they're available, that's good. You could use them as supportive criteria. That was the logic behind those revised criteria that are discussed by scenario in detail in the article. Dr Berkowitz: Fantastic. That's very helpful. Yeah, as you mentioned this- the criteria reviewed in the article, you have a very helpful figure there with all the branch points of how to get to the diagnosis, but very helpful to hear how you think about combining these tests in practice in different scenarios to get to the final diagnosis. So, IBM is considered an inflammatory myopathy, right? Like dermatomyositis and antisynthetase syndrome and immune-mediated necrotizing myopathy. And yet it gets its own separate article each time we do a Continuum issue on muscle disorders, right? Because it's unique in that it doesn't respond to any immune- immunomodulatory or immunosuppressive therapy like these other inflammatory myopathies. So why do you think, or why is it thought by experts in the field like yourself, that this is an inflammatory myopathy but it, at least from a treatment perspective, appears to behave so differently from the other inflammatory myopathies and doesn't respond to immunomodulatory therapy---or at least we haven't found the right key in the right block of immunomodulatory therapy to treat this disease? Dr Naddaf: That's a great question, and it's an area that I'm particularly interested in from a research standpoint. So, all these entities were classified as idiopathic inflammatory myopathies because they had inflammation on muscle biopsy. And IBM does have inflammation on muscle biopsy. Even when we study gene expression, all the immunoglobulin, interferon-related genes, the data are very, very highly expressed in IBM. However, IBM histopathology is not just inflammation. There are other features of IBM that are shared with other diseases of aging, and IBM only affects the aging population. So, by definition it is a disease of aging, and it shares a lot of similarities with other diseases of aging such as Alzheimer's disease or Parkinson's disease or those others that occur with aging. And IBM, unlike any other idiopathic inflammatory myopathy, it is twice more common in males and does not have a juvenile form. Taking all of this together, we could argue that IBM is a disease of aging, and those diseases usually are very complex and have involvement of different pathways---including but not restricted to inflammatory pathways, disrupted protein homeostasis, mitochondrial abnormalities and so on and so forth. And that's why so far we have not had any luck with any immunosuppressive or immunomodulatory therapy in IBM. Now the type of inflammation in IBM is also different, that's mediated by highly differentiated cytotoxic CD8 cells that may not respond to the other treatment. But again, IBM is not just inflammation, and unfortunately in these complicated disorders, we're still at early stages of understanding them, let alone intervene on them. There have been a lot of progress in the last few years in the area of aging in general, and hopefully we would see some new developments in IBM and in other diseases that would help at least slow down the progression. Dr Berkowitz: Fantastic. Well, we've only gotten an opportunity to scratch the surface of your article today talking about the clinical presentation, diagnosis, and a little bit about some of the challenges in treatment. But there's a lot more for our listeners to refer to in your article related to some of the aspects of management, not yet a disease-modifying therapy, but other important aspects of management and many other clinical pearls in this article. So, I encourage our listeners to take a look at your article in this issue. Dr Naddaf: Thanks a lot.
