Background:

The goal of our study was to identify brain structures in patients with panic disorder (PD) that show changes in 18FDG PET during the treatment with cognitive behavioral therapy (CBT) or antidepressants.

Method:

Twelve patients with panic disorder were studied with [18F]-2-fluoro-deoxyglucose positron emission tomography (18FDG PET) during resting state (condition of random episodic silent thinking, REST). After PET examination patients were randomly assigned to either cognitive behavioral treatment group (6 patients) or antidepressants treatment group (6 patients). After 3 month 18FDG PET examination was repeated in both groups.

Results:

Scores of psychopathology rating scales (CGI, HAMA, PDSS) decreased in both groups. Changes of 18FDG uptake in pharmacotherapy group: decreases were found in a priori hypothesized regions in right hemisphere, in superior, middle, medial and inferior frontal gyrus, superior and middle temporal gyrus, and increases were detected in a priori hypothesized regions, mainly in left hemisphere in medial and middle frontal gyrus, superior, middle and transverse temporal gyrus. Changes of 18FDG uptake in CBT group: decreases were found in a priori hypothesized regions of right hemisphere in inferior temporal gyrus, superior and inferior frontal gyrus, and increases were detected in a priori hypothesized region, mostly in left hemisphere: inferior frontal gyrus, middle temporal gyrus and insula.

Conclusions:

Changes in brain metabolism after treatment either with CBT or with antidepressants were similar in number of brain areas, with prominent right-left difference.
