[Late effects of psychogenic and radiation factors of the accident at the Chernobyl nuclear power plant on the functional state of human brain].

As many as 97 persons, victims to the Chernobyl accident, who developed vegetative dystonia were examined by clinical, ++patho-psychological and electroencephalography methods. 24 patients with vegetative dystonia who had not taken part in the liquidation of the consequences of the Chernobyl accident and not lived in the zones of alienation and radioactive contamination were examined too. In the victims to the Chernobyl accident, vegetovascular dystonia was marked by certain clinical and neurophysiological peculiarities in the form of combined vegetative disturbances and hypochondriac symptoms, signs of the schizoform organic syndrome with diffuse disorders of brain bioelectric activity and irritation of the subcortical structures. The contribution of psychogenic and prolonged ionizing radiation to the formation of changes in brain function in victims to the Chernobyl accident is under consideration.
