The Mind Moments podcast features exclusive interviews with leaders in the field discussing the latest research and disease management strategies across the breadth of neurology, including epilepsy, multiple sclerosis, Parkinson disease, dementia, sleep disorders, and more.

In this episode, "Differentiating Dravet and Lennox-Gastaut: Diagnosis, Research, and What’s Ahead," Joseph Sullivan, MD, director of the Pediatric Epilepsy Center at UCSF, joins Mind Moments to discuss the clinical distinctions between Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS). Sullivan outlines the unique diagnostic profiles, seizure presentations, and genetic underpinnings of each disorder, while also addressing how genetic testing has transformed the approach to DS in particular. He speaks on the future of targeted therapies, highlighting ongoing research in disease-modifying treatments and n-of-1 trials, especially for ultra-rare epilepsies. Additionally, Sullivan explores how the clinical trial landscape is evolving—emphasizing the need for biomarkers, innovative trial design, and better tools for seizure monitoring to improve outcomes in these complex pediatric epilepsies.
