[Clinical electroencephalographic characteristics of the phasic nature of the course of severe cerebrocranial injury]. / Kliniko-élektroéntsefalograficheskaia kharakteristika faznosti techeniia tiazheloi cherepno-mozgovoi travmy.

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.

To obtain electroencephalographic criteria for in-depth occurrence of supratentorial tumours the mathematical theory of image recognition has been used. A map of electroencephalographic signs has been drawn up and 182 patients were coded electroencephalographically. Six signs were obtained with the help of the linear minimax algorhythm and in constructing diagnostic combinations of sign gradations--20 syndromes were fixed with whose help it becomes possible to recognize the depth of the tumour occurrence. Both rules were applied in an examination sequence of 51 EEG. The reliability of the results is as high as 0.95.
