抄録: The longitudinal investigation of 154 children at the age of 6-7 years has been conducted. At the moment of the Chernobyl disaster the children had undergone to radiation exposure in the 30-km zone around the Chernobyl atomic power station and in other areas of severe radiation control in different terms of gestation. The examination included the study of the neuro-psychiatric status as well as psychological testing by the Wechsler Intelligence Scale for Children, clinical-psychological investigation of parents and electrophysiological investigation (EEG). The children exposed to the influence of radionuclides during the prenatal period (the children of the exposed group) manifested significant increase of mental disorders as compared with the control group (90 children of the same age from noncontaminated rural areas of Belarus), which was mainly due to the prevalence of cases of specific developmental disorders of speech and language (18.8 vs 2.2% ; P = 0.0410) and emotional disorders (20.1 vs 6.7% ; P = 0.0047). The average group intelligence quotient (IQ) of the children of the exposed group was relevantly lower than the corresponding average group IQ of the children belonging to the control group (85.4 vs 92.5 ; F001 = 2.44). The frequency of reduced intellectual norm (IQ = 80-89) (44.1 vs 26.7 ; P = 0.0065) and borderline intellectual functioning (IQ = 70-79) (18.8 vs 7.8% ; P = 0.0188) as well as abnormal findings of EEG (15.6 vs 2.2% ; P = 0.0005) was higher in the exposed group than in the control group.
