SUDEP is the sudden, unexpected, non-traumatic death of a person with epilepsy, not due to status epilepticus, and without a known cause found at autopsy. It typically occurs during sleep or after a seizure. The exact mechanism is unknown but likely involves seizure-induced respiratory/cardiac dysfunction.
Frequent generalized tonic-clonic seizures, uncontrolled epilepsy, polytherapy (multiple antiseizure medications), non-adherence, sleep deprivation, alcohol use, intellectual disability, and young adult age. The more risk factors, the higher the risk.
Optimal seizure control (the most important factor), medication adherence, adequate sleep (7–9 hours), avoiding alcohol and drugs, treating comorbidities, seizure action plans for families, and consideration of epilepsy surgery or device therapy (vagus nerve stimulation) for drug-resistant epilepsy.
