[RESEARCH OF NON-VERBAL INTELLIGENCE IN CHILDREN AND ADOLESCENTS WITH EARLY SCHIZOPHRENIA AND IN HEALTHY PEOPLE]

The purpose of the study is to determine the degree of decrease in the intellectual level of people under the age of 45 who have suffered from schizophrenia in childhood and adolescence in comparison with healthy individuals of the same age. 700 patients under the age of 45 years who had schizophrenia from 9 to 18 years old and underwent treatment at the Center for Mental Health and Prevention of Addiction (Tbilisi, Georgia) and 479 healthy people of the same age range were examined. In this work, the IQ intelligence coefficient was selected as the measured variable, which was determined both in the patient group and in the control group according to the Wechsler Abbreviated Scale of Intelligence method and its part concerning non-verbal intelligence was used. During statistical processing of control group data for comparison with a group of patients, the data of unrealistically low values and extremely high IQ values were withdrawn from consideration. For patients, a violation of the law of the normal distribution of the IQ coefficient was obtained. The degrading effect of schizophrenia in childhood and adolescence on IQ is very "significant" and is an explanation for the patients' IQ deviation fact from the normal distribution. The median IQ of the control group of healthy people is slightly more than 117, which can be explained by the influence of personal and contextual (modern social environment) factors.
