[Status of the nervous system in victims of the accident at the Chernobyl atomic power plant].

Under neurological investigation were 113 patients with different degrees of severity of acute radiation disease (ARD). The patients were relatively evenly irradiated by beta- and gamma-rays as a result of CPP accident. The onset time and markedness of the signs of primary reaction were related to ARD severity. Early appearance of the signs of disturbances in the central nervous system functional state suggested a stronger affliction, malignant course and fatal outcome of the disease. Ii ARD patients with IV-th and III-rd degree of severity the syndromes observed were these: acute radiation encephalopathy immediately caused by the ionizing irradiation of the CNS, and a secondary radiation-toxic encephalopathy. The hemorrhagic lesioning of CNS and cerebral hemispheres were noted in terminal stages. In rehabilitation phases, neurasthenic and neurovascular syndromes appeared irrespective of the ARD severity.
