This book builds on earlier works focusing on the clinical problem of sudden unexpected death in epilepsy (SUDEP). Developed over the last two years, the SUDEP Classification System and Risk Factor Cluster ID method will help to address gaps in knowledge about the causes and possible prevention of this tragic complication. The book includes case studies of SUDEP and discusses how physicians can identify individuals at risk for SUDEP and possibly lessen the chance of occurrence. It also describes related clinical and animal studies needed to classify risk factors for SUDEP victims.
