[Structural characteristics of the EEG in the secondary stem syndrome in patients with acute circulatory disorders in the cerebral hemispheres].

The authors analyse changes seen in the EEG and secondary dysfunction of the brain stem structures in patients with acute disorders of circulation in the brain hemispheres. On the basis of implicative analysis of the clinico-morphological and EEG data the authors come to the conclusion on the existence of significant EEG criteria in secondary dysfunctions of brain stem structures on the different stages of its development. The significance of EEG in differential diagnosis of primary and secondary brain stem lesions is stressed.
