Subjective sleep disturbance in epilepsy patients at an outpatient clinic: A questionnaire-based study on prevalence

The results emphasize the extent of the comorbidity of sleep disorders and epilepsy in an outpatient clinic. They have higher frequency of sleep onset, maintenance insomnia, probable RBD, and sleep apnea than healthy controls do. The severity of epilepsy can increase the risk of some sleep disorders like insomnia and sleep apnea. Aggressive treatment of nocturnal seizures and EEG can be considered to prevent insomnia. On the other hand, chronicity can lead to sleep apnea and so PSG investigations can be routinely done in patients having video-EEG monitoring due to refractory epilepsy.
