EEG POWER MODIFICATIONS IN PANIC DISORDER DURING A TEMPOROLIMBIC ACTIVATION TASK - RELATIONSHIPS WITH TEMPORAL-LOBE CLINICAL SYMPTOMATOLOGY

Computerized EEG activity derived from the temporal lobes was investig ated in normal subjects and panic disorder patients with and without d epersonalization and/or derealization, in a resting condition and duri ng an odor stimulation task. Panic patients without depersonalization or derealization showed an increase of fast and a decrease of slow act ivities independent of odor stimulation. Panic patients with depersona lization and/or derealization showed an increase of slow activity and bilateral lack of responsiveness in the fast alpha frequency band duri ng odor stimulation. Findings suggest there are different EEG patterns in the temporal regions of the two different groups of panic patients during rest and activating conditions.
