[Polygraphic features of the structure of nocturnal sleep in pathology of the left and right hemisphere in stroke patients].
The results of polygraphic examination of night sleep in 40 post-stroke patients are presented. In 22 of these patients, the focus was localized in the left, and in 18, in the right hemisphere. The pattern of sleep was found to vary with the hemispherical lateralization of the pathological process. Patients with damage to the left hemisphere and aphasia exhibited differences in the phase of rapid sleep and the time-course of the activation phenomena on the EEG during sleep related to the degree of speech disturbances. When the right hemisphere was impared, the most marked disturbances of the sleep pattern were elicited in patients with prominent manifestations of anosognosia. The data obtained are considered as features characteristic of the dysfunction of the cerebral nonspecific systems associated with hemispherical damage.
