Study Summary

The purpose of this study is to examine if treatment of post-traumatic stress disorder in combat veterans with paroxetine changes brain responses as measured by functional magnetic resonance imaging and if brain responses can predict who will get better with treatment.

Primary Outcome

Mean percent change in brain response in the prefrontal cortex during an emotion reappraisal task in the treatment (paroxetine) group and in the Combat Exposed Control group. Target areas are analyzed from fMRI scans which were completed before participants receive treatment and again after participants received 12 weeks of treatment with paroxetine (20-40mg QD). Combat Exposed Control participants received an fMRI scan after signing initial consent and again 12 weeks later.
