Current Knowledge/Study Rationale: Sleep disorders are frequent in stroke patients. There are conflicting data regarding the association between excessive daytime sleepiness, sleep-disordered breathing, and restless legs syndrome. The aim of this study was to explore the association of excessive daytime sleepiness with sleep-disordered breathing, restless legs syndrome, and other clinical characteristics in patients with acute ischemic stroke.
Study Impact: Our study confirmed high prevalence of sleep disorders in patients with acute ischemic stroke. Presence of restless legs syndrome, diabetes mellitus, and body mass index were the only independent variables significantly associated with the measures of daytime sleepiness (the Epworth Sleepiness Scale). In acute ischemic stroke, restless legs syndrome, obesity, and metabolic factors seem to be the most important variables associated with the measures of daytime sleepiness, whereas the role of sleep-disordered breathing seems to be minor.
