Serotonergic Mechanisms of Seizure-Induced Central Apnea Seminar

Wednesday, February 23, 2022
1:00 pm - 2:00 pm CST
Online
Speaker: George Richerson, MD, PhD

Respiratory dysfunction following generalized convulsive seizures is proposed as a causal mechanism in SUDEP. Central chemosensitivity to carbon dioxide, or CO2, drives ventilation in response to hypercapnia, especially during sleep. Dr. Richerson and colleagues have found that this response may be impaired in people with epilepsy, and that convulsive seizures lead to prolonged inhibition of the ventilatory response to hypercapnia.

In a mouse model of Dravet syndrome, Dr. Richerson’s team has obtained evidence that seizures inhibit serotonin neurons that detect changes in CO2 levels. Defining the mechanisms of seizure-induced central apnea may lead to novel preventative treatments for SUDEP.
