Research in South Korea has provided new evidence for an association between epilepsy and sleep disturbance.Led by Seoul National University Bundang Hospital, the study aimed to document the frequency of sleep problems in subjects with epilepsy and determine factors associated with these difficulties.A total of 180 people with epilepsy and 2,836 ‘healthy controls’ were recruited, and information was obtained for each person about sleep problems (relative to age), gender, body mass index, alcohol intake, smoking, perceived sleep insufficiency and habitual snoring.The results of the analysis, which are published in the medical journal Epilepsy & Behavior, showed that sleep disturbance was more common in the epilepsy group than in controls, and that poor sleep quality, excessive daytime sleepiness and insomnia were all significantly linked to epilepsy. In addition, people with epilepsy who had experienced seizure remissions for the previous year were generally found to have insomnia less often. As expected, depressive mood, anxiety and perceived sleep insufficiency were also associated with sleep disturbance.The research concludes: “Epilepsy was significantly associated with the higher frequency of sleep disturbances, which supports the importance of screening sleep problems in patients with epilepsy and providing available intervention.”Click here for more articles about conditions related to epilepsy.
