Abstract

The goal. In order to study the features of the EEG of the brain with a newly diagnosed depressive episode during 2019-2021, in compliance with the principles of bioethics, on the basis of informed consent, 73 patients (35 men and 38 women) with a newly diagnosed depressive episode who applied for outpatient psychiatric care were examined.
Materials and methods. To solve this goal, clinical-anamnestic, clinical-psychopathological, psychodiagnostic, neurophysiological and statistical methods were used.
According to the results of the study, it was revealed that in the vast majority of the cases (78.4%), the newly detected depressive episode was characterized by a decrease in the systemic and coherent interaction of the posterior temporal and occipital parts of the left hemisphere with the right frontal compartments, in combination with an increase in their general activity. A direct correlation was also established between the severity of the clinical manifestations of depressive
disorder and an increase in the activity of the right-sided frontal and left occipital regions in combination with an increase in the general dysfunction of the deep structures of the brain.
Conclusions. In patients with moderate and high levels of depression in the occipital region of the left cerebral cortex, a stable focus of increased alpha activity was established in combination withan increase in the gamma of activity in the right frontal region. In addition, in patients with pronounced clinical signs of depressive syndrome, a steady increase in the power of high-frequency ranges was established, in terms of the average spectral power of EEG rhythms, compared with the control group.
