[Dynamics of bioelectric activity of the brain in the acute period of stroke and its prognostic significance].
The electrical activity of the brain was assessed in various periods of acute ischemic stroke and its values correlated to the neurological symptoms. Seventy-six patients with acute ischemic stroke in the median cerebral artery basin were examined. A grave course of the disease and slowly progressing positive shifts in the neurologic symptoms were associated with the phenomenon of clinico-EEG-dissociation: an increase in the intensity of abnormally slow activity was wave-like and recorded both in the involved and intact hemispheres. These pathological shifts were maximally manifest at the site of projection of ischemic stroke on days 3, 7, and 14 of acute disorder of brain circulation, this permitting the use of EEG parameters in these days with prognostic purposes.
