Computerized EEG activity derived from the temporal lobes was
investigated in normal subjects and panic disorder patients with and
without depersonalization and/or derealization, in a resting condition and
during an odor stimulation task. Panic patients without depersonalization
or derealization showed an increase of fast and a decrease of slow
activities independent of odor stimulation. Panic patients with
depersonalization and/or derealization showed an increase of slow activity
and bilateral lack of responsiveness in the fast alpha frequency band
during 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.Abstract Teaser
