EEG and CT findings in patients with panic disorder

Fifty-four patients with panic disorder were investigated using extensive electroencephalographic (EEG) recordings and computerized tomography (CT). Fifteen (28%) of these patients had previously been treated for temporal lobe epilepsy or were considered to have another neurological disorder. EEG recordings showed increased slow-wave activity in 13 (24%) patients and CT scan revealed incidental abnormalities in 6 (20%) of the 30 patients investigated. Taking into account the limitations of the methods applied, the present results indicate that clear-cut epileptic EEG patterns only rarely occur in panic disorder: the vast majority of panic patients exhibit normal EEG and CT findings.
