FIELD: medicine. SUBSTANCE: method involves determining indices of central parts of lateral ventricles (CPI), anterior horns of the lateral ventricles (AHI), third ventricle(I3V), third ventricle width (I3V), fourth ventricle width (I4V), sulci number (SN). Discriminant function value is calculated as Z= - 18.376+0.448CPI+0.3634SN+0.1854AHI+0.1534I4V+0.1416I3V+0.110I 3V. Value of Z > 0.3853, diagnosis of effective psychosis aggravated by residual organic insufficiency with remittance course is to be set. Z <0.3853 being the case, diagnosis of psychosis without residual organic insufficiency is to be set. EFFECT: enhanced accuracy of diagnosis.
