[The electrophysiological characteristics of brain function in mental disorders in participants in the cleanup of the aftermath of the accident at the Chernobyl Atomic Electric Power Station].
150 liquidators who had worked in the Chernobyl accident area were examined. All of them had mental diseases. Both alpha-rhythms disorganisation and increase of beta-1 activity were usually observed in brain cortex sensomotor areas of 43 patients as compared with 17 healthy individuals. Meanwhile alpha-activity was significantly decreased especially in the left hemispheres of patients with psycho-organic syndrome. The majority of patients were characterized by both enhanced reaction to light flashes rhythm assimilation and the decrease of nonspecific and skin-galvanic reactions to the light stimulus. The conclusion is made about the systemic CNS damage in such patients that was more pronounced in psycho-organic syndrome.
