The possibility of computer-assisted diagnose of schizophrenia, manic-depressive psychosis, psycho-organic++ syndrome according to the structure of EEG components interaction was studied in patients and healthy individuals. Differential diagnose was performed using discriminant analysis of the EEG pattern structure in single leads and in 8 simultaneous leads as well (16 and 128 variables, respectively). Local and spatially-organized discriminants were singled out that allowed to diagnose distinct nosologic forms. The technique allowed to perform computer diagnostic of psychoorganic syndrome with the 78% accuracy. This parameter was 75% for schizophrenia and 71% for manic-depressive psychosis. Healthy subject were diagnosed with 90% accurateness. Differential diagnosis among schizophrenia and other disorders proved most difficult.
