Radiologic imaging of sleep disorders in patients with acute ischemic stroke

Abstract

Sleep is an important and complex physiological process that is necessary for the normal functioning of any organism. Sleep disorders diagnostics is an issue of interest in patients with acute ischemic stroke management. Currently these disorders are considered not only as a consequence of earlier stroke but as an acute cerebrovascular disease risk factor itself. Sleep disorders in patients with acute cerebrovascular disease can be presented in different types, including: insomnia, sleep apnea, central disorders of hypersomnolence, circadian rhythm sleep-wake disorders, parasomnias, sleep related movement disorders, unspecified sleep related disorders.There are very few publications on the subject of sleep disorders associated with acute ischemic stroke, despite the fact that imaging of each of these conditions separately occupies a significant place in radiology.Polysomnography is considered to be the gold standard in sleep disorders diagnostics. Contrary to that, the precise imaging of acute cerebrovascular accidents requires high-technology modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI).The article represents a current literature review regarding radiologic methods in diagnostics of sleep disorders in patients with acute ischemic stroke anamnesis.
