Prognostic Value of Electroencephalographic and Neuropsychological Indicators of the State of Regulatory Functions of the Brain to Assess The Likelihood of Behavioral Abnormalities in Adolescents

Abstract

The paper presents the results of a prognostic model of the occurrence of deviant behavior based on neurophysiological and neuropsychological indicators of behavioral regulation functions in adolescents. We used data on the state of the regulatory systems of the brain obtained on the basis of EEG analysis, data on the state of brain executive functions (EF), obtained on the basis of a neuropsychological examination, and the results of computer tests aimed at evaluating various components of attention. The study involved 166 adolescents, 69 of them with signs of deviant behavior. Using logistic regression analysis, it was shown that EEG-signs of suboptimal RS performance and evaluation of individual EF components (i.e. the ability to form and maintain an acquired action plan, signs of inertia and perseveration) can be significant predictors of deviant behavior. Computer test results showed poor predictive ability. A general model is also proposed that includes predicted probabilities of adolescents belonging to a group with signs of deviant behavior based on the results of using all three methods. A prognostic accuracy of the model is quite high.
