I just finished interviewing Sara Hassani for this week's Neurology Podcast. For today's Neurology minutes, Sara, I'm hoping you can tell us the main points of your paper. Dr. Sara Hassani:  I would say that the central message of this paper is that paraprocedural neurologic complications, they're very common, and they may actually be as high as the third leading cause of mortality, and yet very few healthcare providers realize this. And furthermore, few healthcare providers are adequately prepared to discuss the risks of the various procedures with patients and/or their family members. Dr. Greg Cooper: Thank you for that summary and all your work on this topic. Please check out this week's podcast to hear the full interview, and read the full article published in Neurology, Paraprocedural Brain Health. Thank you.

Dr. Jessica Ailani and Dr. Richard Lipton discuss future advancements in headache medicine.  Show transcript:  Dr. Jessica Ailani:  Hello and welcome to the Neurology Minute. I'm Jessica Ilani from Georgetown Headache Center in Washington, DC. In the neurology podcast with Richard Lipton from the Montefiore Headache Center, we'll be discussing the latest clinical trials in headache medicine, where our field is going, where it's been, and you'll get lots of great advice on thinking through a clinical trial, what the advances have been, where their pitfalls have been, and really how to think of both positive and negative trials. So Richard, what are you most looking forward to when it comes to new treatment targets within headache? Dr. Richard Lipton:  First, let me say that I'm sure most know about the eight CGRP targeted treatments have been approved for migraine, both as acute and preventive treatments. And it's very clear that those treatments have had incredible benefits for our patients and have really improved headache practice. There's another neuropeptide target also targeted by monoclonal antibodies called PACAP or pituitary adenolyte cyclase activating polypeptide. This peptide is also a potent vasodilator involved in pain signaling like CGRP. While CGRP is primarily linked to sensory pathways, PACAP is found in parasympathetic ganglia. And for that reason, it may have a special role in headaches associated with cranial autonomic symptoms. And that includes both migraine, which commonly has cranial autonomic symptoms and also cluster headache. There's a recent randomized trial published in New England Journal showing that a monoclonal antibody targeting PACAP reduced monthly migraine day frequency and was beneficial in people who failed to respond to CGRP inhibitors. So that's at least one area that I'm hopeful about. Dr. Jessica Ailani:  So Richard, thank you so much. I hope you have a few moments and listen to our full podcast that'll tell you a lot more about the future of headache medicine. 

In part one of this series, Dr. Aaron Zelikovich discusses the trial design and primary results.  Show citation:  Solomon T, Hooper C, Easton A, et al. Safety and efficacy of adjunct dexamethasone in adults with herpes simplex virus encephalitis in the UK (DexEnceph): a multicentre, observer-blind, randomised, phase 3, controlled trial. Lancet Neurol. 2026;25(2):136-146. doi:10.1016/S1474-4422(25)00454-5  Show transcript:  Dr. Aaron Zelikovich:  Welcome to today's Neurology Minute. My name is Aaron Zelikovich. I'm a neuromuscular specialist at Lenox Hill Hospital in New York City. Today, we'll discuss part one of a three-part series reviewing a recent article titled Safety and Efficacy of Adjunct Dexamethasone in Adults with Herpes Simplex Virus Encephalitis in the United Kingdom (DexEnceph) Study, a multicenter observer-blind randomized phase three control trial published in Lancet Neurology. In the first episode, we'll focus on the trial design and primary results. In part two, we'll discuss the clinical implications for patients with HSV encephalitis, and in part three, discuss the outcomes seen across the trial during and after an acute infection. Overall, the study found that adjunct dexamethasone did not improve outcomes in patients with CSF-confirmed HSV encephalitis. But importantly, it also did not worsen outcomes. Prior research that was non-randomized and retrospective of 45 patients with HSV encephalitis found that patients did not receive corticosteroids had worse outcomes. A different randomized trial looking at dexamethasone and HSV encephalitis was only able to recruit 41 patients and was stopped prematurely due to the lack of recruitment. Prior to the study, there was no clear evidence that adjunct steroids with acyclovir improved outcomes in HSV encephalitis. The Dex and phase three randomized clinical trial performed in the United Kingdom at 53 hospitals recruited patients from 2016 to 2022. They screened over 1,400 patients of which only 94, or 6%, were enrolled. Patients were randomized to either acyclovir only or acyclovir and intravenous dexamethasone. In order to be randomized, patients had to have a febrile illness with new onset seizure or new focal neurological sign or altered mental status as well as a positive HSV type one or two PCR from the CSF. The primary outcome for this study was the Wechsler Memory Scale Type Four Auditory Memory Index Score which was collected at 26 weeks. It had a range of 40, which is the worst outcome, to a range of 160 which was considered normal. 81 patients were included in the modified intention-to-treat analysis. Of the 13 patients, six were lost to follow-up, and seven withdrew consent. There were 39 patients in the dexamethasone group and 42 in the acyclovir-only group in the final analysis. The primary outcome of the Wechsler Memory Scale had similar scores in both groups. 71 in the dexamethasone group and 69 in the control group with a P value of 0.76. The safety profile was similar in both groups, and there were no additional safety signals found in the dexamethasone-treated group. At 26 weeks, there were 12 deaths from HSV encephalitis, six from each group, as well as a similar time to discharge between both cohorts. The DexEnceph clinical trial did not show any clear clinical benefit for dexamethasone with regards to clinical outcomes but also didn't show any increased safety concerns compared to only acyclovir. In part two, we will discuss the implications of this trial in patients with undifferentiated encephalitis and the role that steroids play in patients that HSV encephalitis is suspected. Thank you so much, and have a wonderful day.   

In the second part of this series, Dr. Tesha Monteith and Dr. Jennifer Robblee discuss updates to the emergency room recommendations for the acute treatment of migraines.  Show citations:  Robblee J, Minen MT, Friedman BW, Cortel-LeBlanc MA, Cortel-LeBlanc A, Orr SL. 2025 Guideline Update to Acute Treatment of Migraine for Adults in the Emergency Department: The American Headache Society Evidence Assessment of Parenteral Pharmacotherapies. Headache. 2026;66(1):53-76. doi:10.1111/head.70016 Robblee J, Khan FA, Marmura MJ, et al.

I've just been speaking with Jennifer Robblee about her exciting work, defining refractory migraine with an international consensus, as well as her work with the American Headache Society on a guideline update for parental pharmacotherapies for migraine in the emergency department. So Jennifer, we've just been chatting on the podcast about all the great work out of the American Headache Society, updating the emergency room recommendations for acute treatment of migraine. Can you give a summary of those findings? Dr. Jennifer Robblee:  We looked at all of the new data for randomized control trials in the emergency room. We found 26 new trials, and several of those were actually a class one study that we felt had a low risk of bias. And from that, we applied the grading. So we actually have two grade A medications where it is that you must offer, of course, to the appropriate patient. And that's prochlorperazine IV, and greater occipital nerve blocks. Now, there's also a grade A must not offer, and that's IV hydromorphone. Then we have some grade B, which is should offer, and that's dexketoprofen, ketorolac, metaclopramide, sumatriptan subcutaneous, and supraorbital nerve blocks. So really exciting that we have lots of things that we can now say we have pretty good evidence or very good evidence to offer them to our patients. Dr. Tesha Monteith:  Great. It's always nice to see this update based on evidence. Dr. Jennifer Robblee:  Yes, I think it's so important, because right now when we see patients, and I'm sure you get this all the time, they come back, say they were in the emergency room for a severe headache and they got a migraine cocktail. And you're like, "Do you know what you were given?" And they say, "I don't know. I was just told it's a migraine cocktail." And as you know, that mean many, many different things. And when you are able to pull the records, it is many, many different things that a migraine cocktail can mean. So I'm hoping that this can start to standardize what we're actually giving our patients as we await more trials in the future that might start to tell us what that combo of treatments really should be. For right now, these at least tell us what individual treatments have the best evidence. Dr. Tesha Monteith:  Thanks so much, Jennifer.  

In this episode, Dr. Jason Crowell reviews the March 9th Capitol Hill Report discussing the AAN's advocacy priorities for 2026. Stay updated with what's happening on the hill by visiting aan.com/chr.  Learn how you can get involved with AAN advocacy.  Show transcript:  Dr. Jason Crowell: Hey, this is Jason Crowell. Thanks for listening to today's Neurology Minute. Today, we have an advocacy update from the AAN's Capitol Hill Report. The AAN has come out with its top advocacy priorities for 2026, and the first is access to care which includes affordable prescription drug prices, telehealth, and adequate coverage policies. Neurological conditions can require expensive specialty drugs as we know, so the AAN supports policies that ensure prescription medications are accessible to patients. Related to this priority, the Center for Medicare and Medicaid Innovation recently announced the GLOBE and GUARD models, two proposed mandatory drug pricing models that would make manufacturers pay rebates if their drug prices exceed global benchmarks. The AAN has responded to these proposals with recommendations to avoid unintended access issues. It's also important to make telehealth flexibilities permanent for Medicare beneficiaries, and the AAN has been lobbying for the CONNECT for Healthcare Act to do that. The second top priority is reducing regulatory and administrative burdens, like prior authorization and step therapy which we're familiar with. This is a longtime problem for physicians who spend a lot of time each week. We deal with these processes and we'd rather be treating patients, as you know. A new Medicare initiative called the WISeR Model establishes new prior authorization requirements for some medical services, and while it doesn't directly affect neurology, the AAN and other organizations are pushing back and closely monitoring for future similar models. Next is the neurology workforce. This includes making sure Medicare reimbursement for neurological services is enough to maintain a practice, as well as supporting wellness and immigration policy to allow international medical graduates to practice in the US. Related to this priority, the AAN has been pushing for a permanent inflationary update to the Medicare Physician Fee Schedule and to end the schedule's outdated budget neutrality requirement that ends up causing cuts to reimbursement each year. The final priority is neuroscience research and brain health. There have been a lot of threats to research funding recently, and the AAN has been lobbying for NIH and NINDS funding that includes the BRAIN Initiative, an important program that's led to neurology breakthroughs. It's set to lose a big part of this funding at the end of the year when funding from the 21st Century Cures Act expires. So the AAN has been asking Congress to help make up the gap through appropriation spending.
