[Comparative analysis of EEG characteristics in patients with acute phase of ischemic stroke (according to data of computer electroencephalography)].

A complex clinical and computer-assisted EEG study was carried out. 97 patients with acute ischemic cerebral hemisphere and 27 patients with acute ischemic brain stem stroke have been observed. A computer-assisted EEG was found to improve considerably diagnostic quality of stroke patients. It enables to determine the degree of functional lesions of the brain. Local changes of EEG-pattern prevail in patients with acute ischemic cerebral hemisphere stroke. Patients with acute ischemic brain stem stroke developed diffuse changes of EEG-pattern. Background EEG is the most representative technique to reflect bioelectric activity of the brain and it enables to assess the plasticity and reactivity of processes of the brain.
