[Topical electrophysiological correlates of emotional states (on the evidence of incipient hypertension encephalopathology)].

Comprehensive investigations of 97 patients with incipient hypertension encephalopathologies were performed with the use of standard psychodiagnostic questionnaires and EEG. Topographic analysis of spectral power showed stable constellation of altered alpha- and beta-zones in the EEG parietal, temporal and occipital leads. Given the clinical implications of this finding, we can view it as a potential neurophysiological background for depression, and a "functional" phase in disease development.
