[Systemic organization of EEG in patients with different forms of schizophrenia]

The EEG of the frontal, temporal, parietal and occipital areas of the brain were examined in patients with recurrent, shift-like, simple and paranoid schizophrenia as well as in healthy persons. Analysis of the EEG involved two stages, using computer. Making use of the distinguished discriminant functions--components (waves) of the EEG interrelated in a definite manner, which may be "EEG markers", it turned out possible to perform differential computer-aided diagnosis of healthy persons and patients with different schizophrenia patterns. In patients with the recurrent and paranoid patterns, the accuracy of coincidence of the clinical diagnosis with that established by means of computer appeared to be equal to 61%. In groups with shift-like and simple schizophrenia, the accuracy amounted to 35 and 33%, respectively.
