Sudden unexpected death in epilepsy (SUDEP) has been defined as occurring in an individual suffering from epilepsy (characterized by recurrent seizures), who dies unexpectedly while in a reasonable state of health, and with death happening suddenly (in minutes), and during normal activities and benign circumstances. Also there should be no obvious medical cause, and death should not be the result of a seizure or status epilepticus, such as inhalation of vomit.
