title: [The characteristics of the structure of night sleep in patients who have had a stroke].
abstract: The aim of the study was investigation of the structure of the night sleep in relation to the disease stage and location of the destructive focus. 18 patients with ischemic stroke (in the right hemisphere-8 cases, in the left one-6 persons, with brain stem location-4 patients) were observed as well as 5 practically healthy individuals. The diagnosis was verified by computer tomography in all cases. Clinical neurological investigation and polygraphy of night sleep (electroencephalography, electrooculography, electromyography) were performed. Analysis of sleep parameters was carried out according to program elaborated by the Center of Sleep Research of Sechenov Moscow Medical Academy. This program includes the analysis of segmental sleep structure in addition to standard parameters. The sleep quality was estimated by Sleep Index (Slind) according to the degree of intactness or destruction of its structure. Rude disorganization of night sleep structure was revealed in the patients, including disturbances of mechanisms of the whole sleep organisation, as well as generation and maintenance of its separate stages. The most rude disorders of sleep in patients with ischemic stroke were connected with location of ischemic focus in right hemisphere and in medial, deep structures.
