PECULIARITIES OF NIGHT SLEEP STRUCTURE IN PATIENTS AFTER CEREBRAL STROKE

The aim of the study was investigation of the structure of the night s leep 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 pat ients) 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 (electroencep halography, electrooculography, electromyography) were performed. Anal ysis of sleep parameters was carried out according to program elaborat ed by the Center of Sleep Research of Sechenov Moscow Medical Academy. This program includes the analysis of segmental sleep structure in ad dition to standard parameters. The sleep quality was estimated by Slee p Index (Slind) according to the degree of intactness or destruction o f its structure. Rude desorganisation of night sleep structure was rev ealed in the patients, including disturbances of mechanisms of the who le sleep organisation, as well as generation and maintenance of its se parate stages. The most rude disorders of sleep in patients with ische mic stroke were connected with location of ischemic focus in right hem isphere and in medial, deep structures.
