Bomko M. Structural-functional characteristic of organic mental disorders in clean-up workers of the consequences of the Chernobyl accident in remote period of exposure to ionizing radiation

On the base of clinical, pathopsychological, neurophysiological investigations and on the base of visual and morphometric assessments of MRIs of 110 clean-up workers of the consequences of the Chernobyl accident and 30 patients of comparison group was revealed the structural-functional cerebral basis in remote period of exposure to ionizing radiation in doses 0,05-4,7 Sv. The decrease of contrast coefficient between left capsule internal and cerebral liquor system because of its hip anterior and genu (0,3-4,7 Sv) and the contrast coefficient between white matter of left parietal lobe and cerebral liquor system (1-4,7 Sv) are neuroimaging markers of ionizing radiation effect. The organic brain damage in clean-up workers of the consequences of the Chernobyl accident in remote period of exposure to ionizing radiation and in remote period of acute radiation sickness (ARS) is etiological heterogeneous as a result of age-related changes, cerebrovascular and somatic pathology, smoking and exposure to ionizingradiation in doses higher than 0,3 Sv.
