Reducing the Risk of Sudden Unexpected Death in Epilepsy (SUDEP)

Abstract

Purpose of Review

Recent reports have highlighted an increase in the number of epilepsy-related deaths. Sudden unexpected death in epilepsy (SUDEP) is thought to be the number one cause of death in chronic epilepsy. This review provides a summary of the current evidence of how to communicate, stratify, and mitigate known risk factors for SUDEP.

Recent Findings

There is now a clearer understanding of the possible pathological mechanisms that contribute to SUDEP. SUDEP is the culmination of multifactorial predisposing and precipitating factors and has been linked to particular candidate genes. A number of static and modifiable risk factors for SUDEP have been consistently identified. Recent guidance has emphasised the importance of communicating SUDEP risk to individuals at the earliest appropriate time.

Summary

SUDEP risk assessment should be integral to the care of individuals with epilepsy. The use of evidence-based risk assessment tools may provide an opportunity to communicate identified risks in a person-centred holistic way. There is increasing evidence to support the use of wearable seizure monitoring devices to help reduce the frequency and impact of convulsive seizures, perhaps the number one risk factor for SUDEP.
