FIELD: medicine.
SUBSTANCE: invention relates to medicine, psychiatry, diagnostics. EEG is performed using “10–20” leads and ipsilateral ear electrodes as reference, followed by spectral and coherent analysis. Determine the power spectrum in the frequency range of 4–8 Hz and in the frequency range of 0.5–30 Hz in F3 lead, in the range of 20–21.5 Hz in F4 lead; coefficients of intra-hemispheric coherence in the frequency range of 12–13 Hz between T3–01 leads, in the frequency range of 29–30.5 Hz between F3-C3 leads and in the frequency range of 5–6 Hz between T4-C4 leads, calculate the indicator Y from the original mathematical formula. If the value of Y is less than zero, schizophrenia is diagnosed.
EFFECT: method allows to increase the accuracy of diagnosis of schizophrenia.
