Many studies have investigated the association between headache and sleep disorders, but few have focused on migraine. The goal of this study was to evaluate sleep disturbance and excessive daytime sleepiness (EDS) in relation to migraine disability. 120 migraine patients who were diagnosed according to The International Classification of Headache Disorders-II and 45 healthy controls were recruited for the study. All participants completed the Pittsburg Sleep Quality Index (PSQI), the Epworth Sleepiness Scale, Beck Depression Inventory and Beck Anxiety Scale. Migraineurs completed Migraine Disability Assessment Scale (MIDAS) and Visual Analog Scale. The prevalence of poor sleep was 83.3% in the patients and 22.2% in the controls. All PSQI subgroup scores were higher for the patients than the controls except Hours asleep. EDS was more prominent in the patient group (19.2% vs 2.2%). In conclusion, sleep disturbance, EDS, anxiety, and depressive symptoms were detected more commonly in migraine patients and were correlated with the migraine-related disability. The results of multivariate regression analysis indicated that EDS and sleep disturbance were the most effective factors on disability.
