Finding epilepsy genes: Dr. Allan Bayat

As a neurological emergency, status epilepticus (SE) requires timely diagnosis and treatment. A US study found that 10% of people with SE were not diagnosed by emergency services. Among those who were diagnosed in an ambulance, 20% did not receive any first-line treatment, while others received lower-than-recommended doses. Sharp Waves spoke to senior author Dr. Elan Guterman about the study.Publications mentioned during the conversation:Status Epilepticus Identification and Treatment Among Emergency Medical Services Agencies  JAMA Neurology A Comparison of Lorazepam, Diazepam, and Placebo for the Treatment of Out-of-Hospital Status Epilepticus | New England Journal of MedicineParamedic-Identified Enablers of and Barriers to Pediatric Seizure Management: A Multicenter, Qualitative Study: Prehospital Emergency CareEmergency response to out-of-hospital status epilepticus | Neurology Sharp Waves episodes are meant for informational purposes only, and not as clinical or medical advice.Let us know how we're doing: [email protected] International League Against Epilepsy is the world's preeminent association of health professionals and scientists, working toward a world where no person's life is limited by epilepsy.

Folic acid supplementation is recommended for all women with epilepsy who may become pregnant. However, there is no agreed-upon dose for women with epilepsy taking antiseizure medication, and there may be risks of high-dose (>1 mg/day) folic acid supplementation. Dr. Bruna Nucera spoke with Dr. Marte Helene Bjørk about the risks and benefits of folic acid supplementation and what this means for pregnant women with epilepsy.

High-frequency oscillations (80 to 500 Hz) are being studied as biomarkers of epileptogenic areas in the brain, as well as markers to be used in epilepsy surgery. Dr. Cecilie Nome leads a discussion about clinical research on HFOs and areas of uncertainty, as well as the importance of basic research in helping to understand this phenomenon.Publications mentioned during the episode: Roehri Eng N, et al.

There are potentially hundreds of "epilepsy genes" - but what is an epilepsy gene? How do researchers discover these genes and associate them with epilepsy? Sharp Waves spoke with Dr. Allan Bayat, a pediatric neurologist in Denmark focused on rare monogenic neurodevelopmental disorders and epilepsy.

Christina Rezek and Brad Levy each have daughters who underwent epilepsy surgery, with dramatically different results. Sharp Waves talked with them about the journeys to and through epilepsy surgery, the consequences, and what they have learned.Brad Levy is a founder of Epilepsy Awareness Day at Disneyland, a free event held every November in Anaheim, California, USA.

In this episode, we explore the science behind exercise as an adjunct treatment for epilepsy and debunk some common myths (spoiler alert: With very rare exceptions, exercise does NOT increase seizure risk). Dr. Ayushe Sharma talked with Dr. Jane Allendorfer, Dr. Halley Alexander, and Brian Wiedmeyer, who participated in an exercise research study.The episode refers to a 2016 report by the ILAE Task Force on Sports and Epilepsy - that report is freely available online at this link.Some of the other research papers mentioned in the episode are listed below.The relationship between physical activity and cognitive function in people with epilepsy: A systematic review Effects of physical exercise in people with epilepsy: A systematic review and meta-analysis Role of Physical Exercise as Complementary Treatment for Epilepsy and other Brain Disorders Epilepsy and exercise: An experimental study in female rats Effects of an exercise program on health of people with epilepsy: A randomized clinical trialA strength exercise program in rats with epilepsy is protective against seizuresEffectiveness of Yoga Intervention in Reducing Felt Stigma in Adults With Epilepsy Impact of exercise as a complementary management strategy in people with epilepsy: A randomized controlled trial Sharp Waves episodes are meant for informational purposes only, and not as clinical or medical advice.Let us know how we're doing: [email protected] International League Against Epilepsy is the world's preeminent association of health professionals and scientists, working toward a world where no person's life is limited by epilepsy.

A recent practice guideline provides updated evidence-based conclusions and recommendations regarding in utero effects of anti-seizure medications and folic acid supplementation on the prevalence of major congenital malformations, adverse perinatal outcomes, and neurodevelopmental outcomes. Dr. Parthvi Ravat interviewed Dr. Alison Pack about the guideline, which was produced by the American Academy of Neurology, American Epilepsy Society, and Society for Maternal-Fetal Medicine.Review the practice guideline: Teratogenesis, perinatal, and neurodevelopmental outcomes after in utero exposure to antiseizure medication (Neurology, May 2024)Other studies mentioned in the episode: Risk of major congenital malformations and exposure to antiseizure medication monotherapy (JAMA Neurology, March 2024) Sharp Waves episodes are meant for informational purposes only, and not as clinical or medical advice.Let us know how we're doing: [email protected] International League Against Epilepsy is the world's preeminent association of health professionals and scientists, working toward a world where no person's life is limited by epilepsy.
