[Neurophysiological features in epileptic patients with affective disorders]

The paper presents an analysis of autonomic regulation and spectral EEG structure in 70 epileptic patients with affective disorders in period between the fits. It was found that activity of the sympathetic link was elevated, activity of the parasympathetic link was decreased in such patients especially in cases with partial visceral-autonomic fits. EEG mapping revealed elevation of the spectral power of density (SPD) of alpha-diapason with a simultaneous decrease of 8-9 Hz frequency as well as different location of alpha-rhythm's focus in the patients as compared with healthy individuals. The most frequent prevalence of delta-activity was found in the temporal lobes. In patients with partial visceral-autonomic, psychomotor and psychosensory fits the foci of epileptic activity have been registered in the right hemisphere 3-4 times more frequently than in the left one. After the course of therapy normalization of the indices of autonomic regulation was not observed, individual EEG peculiarities remained, but there was an increase of alpha-rhythm's SPD and a decrease of SPD of delta-range.
