Aim - to study the particularities of clinical course of psychoneurological disturbances in 50 liquidators irradiated in doses of 0.25-1 Gy. Methods - clinical neurological and psychiatric, psychodiagnostic, neurophysiological, neuroimaging, statistical. Particularities of clinical course of nervous system diseases and mental disorders appeared in persistent development of psychoneurological pathology.

Progressive lesion of brain confirmed by consecutive change of hyper-synchronous with predominance of alpha-activity EEGtoward disorganized and polymorphous low-voltage types of EEG. Electroencephalographic signs of organic cerebral lesion (encephalopathy) are as follows: the posterior dominant background slowing <8 Hz and pathological low-voltage EEG.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
