Abstract

Purpose of Review

Sleep complaints are common in people with epilepsy (PWE). We aim to highlight the updated evidence regarding comorbid sleep disorders and epilepsy and the impact of epilepsy and its treatments on sleep.

Recent Findings

Up to two thirds of PWE report sleep disturbances which may signal presence of a comorbid sleep disorder, including insomnia, arousal parasomnias, excessive daytime sleepiness, obstructive sleep apnea, or restless legs syndrome. Uncontrolled seizures contribute to poor sleep quality, while presence of epilepsy (with or without seizures) and antiepileptic drugs is associated with changes in sleep architecture. Chronic intracranial EEG monitoring with implanted devices reveals a nocturnal peak for interictal epileptiform activity. Epilepsy surgery outcomes suggest better seizure control may improve sleep architecture and quality.

Summary

Screening for and treating sleep disorders may lead to improved seizure control and quality of life in PWE. Epilepsy surgery and implanted devices to treat refractory epilepsy provide new insights into the relationship between sleep and epilepsy.
