Diatropics is an evolutionary theory of diversity and the mechanisms of its formation. Identity integration disorder (IID) is a specific mixed form of psychopathological diathesis, characterized by the presence in the personality structure of a combination of symptoms of the three main circles of mental disorders: schizophrenic, epileptic, affective. Our study evaluated the peculiarities of the neurophysiological indices of the brain of persons with IID as consolidating with respect to the main forms of mental disorders, to substantiate the possibility of studying this phenomenon as a diatropic model of mental pathology. A total of 76 subjects with IID and 20 mentally healthy subjects were selected. For neurophysiological examination, cross-correlation analysis of electroencephalography respondents was used. The changes in the connections between the different brain regions of individuals with IID can be described as indicating two main features: 1) a decrease in the degree of interaction between centrally localized structures - the temporal, and upper parietal; 2) an increase in the degree of interaction between the integration of the frontal and occipital regions. The presence of signs of mental disorders in the human population is necessary in order to form a special group of highly intelligent, creatively gifted.
