摘要

Sleep and epilepsy share a complex pathophysiological association. Juvenile myoclonic epilepsy (JME) is a common sleep-sensitive epilepsy in which the effect of seizures could have therapeutic implications in terms of sleep disturbances and seizure control. This study aimed to analyze the effect of epilepsy on sleep in patients with JME. Fifty patients on valproic acid (VPA) monotherapy, and age- and gender-matched controls were recruited into this prospective, hospital-based, case-control study after informed consent and screening for inclusion criteria. They underwent a detailed clinical assessment, electroencephalogram (EEG) and neuroimaging, and were administered validated sleep questionnaires, which included the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI) and NIMHANS Sleep Disorders Questionnaire. The patient and control groups had identical numbers of males and females (M: F = 22: 28), without any significant difference in the age and body mass index (BMI). The clinical profile of JME was similar to published literature while the prevalence of EEG abnormalities was less compared to similar studies. The mean ESS and PSQI scores and the number of subjects with abnormal scores on one or both questionnaires were significantly more in patients. Patients had a higher prevalence of sleep disturbances, insomnia and excessive daytime somnolence. No significant seizure- or treatment-related factors influencing sleep could be identified. This study, the first of its kind, revealed that patients with JME have significant sleep disturbances characterized by excessive daytime sleepiness and disturbed night sleep, despite adequate medications and good seizure control. The role of VPA in the genesis of these symptoms needs clarification.
