[Clinical-electrophysiological characteristics of the cognitive sphere in patients in the acute period of the first cerebral ischemic stroke].
A neuropsychological and neurophysiological study using computed EEG was carried out in 31 stroke patients who did not have a cognitive impairment according to MMSE. Thirty age-matched patients with the same risk factors without a history of stroke were included into the control group. The examination of the control group was performed only once. The examination of stroke patients was performed on days 1, 7 and 21. It was shown that cognitive neurodynamic disturbances (memory disorders and the visual memory decrease) and bioelectrical brain activity disturbances (the decrease in a- and beta band activities and the increase of theta-band power) occurred from the first day and lasted during the acute stroke period even after the improvement of neurological status.
