Abstract:

Objective. To study neurophysiological features of the cognitive activity in patients with anxiety-depressive and hypochondriacal disorders. Material and methods. The study included 65 people: 16 with hypochondriacal disorder, 23 with mixed anxiety and depressive disorder, and 26 control subjects. Heart rate variability method and electroencephalography were used. Results and conclusion. There was a decrease in the beta-1 frequency range in EEG after performing cognitive test in patients with mixed anxiety and depressive disorder. Patients with hypochondriacal disorder had the reduced duration of RR intervals; increased beta-1 frequency range in the resting state; the increase in the dominant beta-2 frequency during the cognitive test, and in the standard deviation of theta-wave frequencies after the cognitive test.

Keywords:

neurotic disorders
hypochondriacal disorder
mixed anxiety and depressive disorder
EEG
heart rate variability
