[Clinical electroencephalographic characteristics of the phasic nature of the course of severe cerebrocranial injury].

In order to early recognize intracranial hematomas and contusions, differential diagnostic criteria for analysis of neurological symptomatology and EEG signs are considered from the standpoint of a phasic clinical progress of traumatic pathological conditions of the brain. The EEG syndromes of initial, pronounced and gross synchronization correlated with the clinical phases of subcompensation, mild and deep decompensation. The study demonstrates a contrary trend in the dynamics of the clinical and EEG data in compression and contusion of the brain.
