Synapses, Aging, and the Quest to Restore Memory

Many women navigate midlife health transitions without clear guidance or open conversations. In this episode of Research Renaissance, host Deborah Westphal is joined by Dr. Sarah Berg and Rachelle Kuramoto, co-founders of Selfority. They discuss the realities of perimenopause, the lack of medical training around women's midlife health, and how they are building educational platforms for both consumers and workplaces to bridge the gap.Key TakeawaysMedical training often provides minimal education on perimenopause and menopause despite it covering a significant portion of a woman's life.The transition can bring unexpected cognitive and physical changes, making accessible, medically authoritative information essential.Selfority approaches this challenge through two main pillars: direct consumer education and corporate workplace programs.Engaging men in the conversation helps build a supportive environment both at home and at work.Main Discussion PointsHow Dr. Sarah Berg transitioned into menopause specialization after noticing gaps in her OBGYN training.Rachelle Kuramoto's journey from brand agency owner to co-founding Selfority to support female founders and women's health.The connection between hormonal shifts in midlife and brain health research involving experts like Dr. Lisa Mosconi and Dr. Pauline Maki.Overcoming workplace stigma and helping leaders support midlife retention.Resources MentionedSelfority website: www.selfority.comPodcast: The AppointmentResearchers mentioned: Dr. Lisa Mosconi, Dr. Pauline MakiIf you enjoyed this conversation, please subscribe, rate, and review the podcast on Spotify or Apple Podcasts.

What happens to our brains as we age? Dr. Victor Luna, a researcher at the Alzheimer's Center at Temple University, joins the show to discuss the biological mechanics of the synapse and why understanding these connections is the key to managing cognitive decline. Rather than trying to magically rejuvenate the aging brain, Dr. Luna explains a new framework for helping the brain function at its optimal level for the age of the patient.Key TakeawaysThe Beauty of the Synapse: Dr. Luna describes the synapse as the language of the brain. It is not just about individual neurons firing, but how they connect to form thoughts, emotions, and memories.Aging is Not a Reset Button: We cannot expect an eighty-year-old brain to operate like a twenty-year-old brain. The goal should be to help the aging brain function at its highest possible capacity, not to force it back to a youthful state.The Power of Lifestyle: Exercise remains the most effective tool we have for supporting neurogenesis and synaptic health, regardless of age.Personalizing Treatment: The lab is developing biostatistical and AI-driven tools to create personalized paths for patients. This aims to shift from a "one-size-fits-all" approach to giving clinicians and families specific options for managing symptoms and maintaining quality of life.Defining Goals: Dr. Luna emphasizes the importance of patients and caregivers identifying which specific cognitive faculties are most important to maintain, whether that means clearing up fogginess or improving memory discrimination.Resources MentionedTemple University Alzheimer's CenterKaren Toffler Charitable TrustIf you enjoyed this episode, please subscribe to Research Renaissance on your favorite podcast platform.

Science communication expert Ellen Kuwana shares her journey from lab technician to professional science editor. With over 25 years of experience, Ellen explains why clear writing and simple language are vital for securing research funding, connecting with the public, and building trust in health science. She breaks down the practical realities of academic life, the flaws of the publish or perish mindset, and how researchers can effectively communicate their work without dumbing it down.Key TakeawaysClear writing reflects clear thinking and reduces the cognitive load on grant reviewers and readers.University research relies heavily on government funding, which helps subsidize basic infrastructure and early-stage discoveries.Communicating science to non-scientists is not about dumbing down concepts, but sharing the original wonder, purpose, and real-world impact of the work.Short attention spans require flipping the standard academic format by placing main points and key takeaways up front.Moving away from closed off academic structures toward transparent, relatable storytelling builds stronger public engagement.Main Points DiscussedFrom the Lab to Editing: Ellen traces her upbringing in an academic home to her time as an NSF-funded master's student and lab technician, outlining how she recognized the need for dedicated science editors.The Reality of Academic Funding: How federal grants power university labs, pay salaries, and absorb overhead costs to keep research systems moving.Structuring for the Modern Reader: Why traditional journal formats delay important details and how front-loading key insights serves readers and AI optimization alike.Navigating Misinformation and Generative AI: The importance of maintaining human oversight, checking references, and recognizing the limitations and environmental footprints of AI tools in research writing.Encouraging the Next Generation: Why early career researchers and trainees should embrace public outreach, share their everyday lab experiences, and own the title of scientist.Resources MentionedNational Science Foundation (NSF)National Institutes of Health (NIH)Pew Research CenterEcosia Search EngineIf you found value in this discussion, please subscribe to the podcast, leave a rating, and share this episode with a colleague or friend interested in health science and research.To learn more about the breakthroughs discussed in this episode and to support ongoing research, visit our website at tofflertrust.org.

Mental health care often feels disconnected from the rest of medical science. Dr. Greg Witkop, senior advisor for mental health at Renaissance Philanthropy, argues that it is time to treat the brain like any other organ. This conversation explores how we can bridge the gap between neuroscience and psychiatry to create more effective, data driven treatments that move us beyond simple symptom labels.Key TakeawaysMental health is brain health, and treating it with the same biological rigor as cardiology or oncology is essential.Current diagnostic labels often act as an epistemic prison that limits our ability to treat the underlying physiological causes of suffering.A precision psychiatry approach requires a biopsychosocial model that considers biology, social support, and environment equally.We are currently at an inflection point where imaging, modeling, and interventional tools allow us to treat mental health with real measurable outcomes.Main PointsDr. Witkop shares his unique career journey, moving from ophthalmology and the FBI to DARPA, and why he now focuses on bringing rigor to mental health research. They discuss the historical silos between psychiatry and neuroscience, and why these divisions persist despite the fact that the brain constructs our entire subjective experience. The conversation also highlights the urgent need for a new ecosystem of care that mirrors models like St. Jude's or cancer research centers, focusing on shared protocols and patient outcomes rather than just stabilization.ResourcesRenaissance PhilanthropyNational Institute of Mental Health (NIMH)The Precision Psychiatry Roadmap (Molecular Psychiatry, 2025)Now Matters Now organizationIf you found this discussion valuable, please subscribe to the show on your favorite podcast platform and share this episode with a colleague or friend.

What if diagnosing PTSD, anxiety, and depression could be as objective as a blood test — done in 10 minutes on your phone?That's the vision behind Sensei, a company using AI and ocular biometrics to bring measurable, objective diagnostics to mental health. In this episode, host Deborah Westphal sits down with David Zakariaie, founder and CEO of Sensei, to talk about the science of the eye, a $2M technology problem solved with a commercial camera, and why fixing mental health starts with fixing measurement.Key TakeawaysMental health's biggest crisis isn't just a shortage of care — it's a measurement problem. Major depression, the most commonly diagnosed mental health condition in the U.S., is misdiagnosed approximately 65% of the time. PTSD, bipolar, and schizophrenia are misdiagnosed between 84–92% of the time.Sensei's diagnostic app shows patients a series of ocular stimuli for roughly 10.5 minutes, captures their eyes' responses via a standard smartphone camera, and outputs a binary diagnosis plus a severity score.The platform measures approximately 45 individual metrics across three categories: traditional ocular metrics (pupil size, blinks, saccades, gaze), iris dilator and sphincter dynamics (mapping sympathetic vs. parasympathetic nervous system activity), and heart rate and heart rate variability from facial video.Sensei is currently in Phase 3 clinical trials for a PTSD diagnostic, with an FDA submission planned for late 2025 and approval expected in 2027.About 16,000 people participated in pre-trial studies; the full dataset at submission is expected to reach approximately 30,000.The go-to-market strategy focuses on telehealth platform integration — partnering with companies like Spring Health, Talkspace, and BetterHelp to embed the diagnostic tool directly into existing care delivery workflows.Future expansion targets schizophrenia, bipolar disorder, and ADHD, with longer-term interest in neurodegenerative conditions like Alzheimer's and dementia.About David ZachariaDavid Zakariaie is the founder and CEO of Sensei, a mental health diagnostics company building the first FDA-regulatory-grade platform for diagnosing and monitoring PTSD, anxiety, and depression using AI-powered ocular biometrics. His path began at 15, when he attended Google I/O, received an early pair of Google Glass, and became fascinated with the scientific potential of the human eye. He left high school after 10th grade, taught himself to code, and launched the company in 2015.Resources & Links MentionedSensei: sensei.health (verify current URL)Mental Health Study (Phase 3 Trial Sign-Up): mentalhealthstudy.orgKaren Toffler Charitable Trust: tofflertrust.org (verify current URL)Parea Therapeutics (digital therapeutics reference)The CAPS-5 (Clinician-Administered PTSD Scale)The PCL-5 (PTSD Checklist for DSM-5)If You Enjoyed This EpisodeSubscribe to Research Renaissance wherever you listen to podcasts.
