Six drug-free obsessive-compulsive patients were given single photon
emission computerized tomography scans before and during treatment with
fluoxetine. The treatment significantly reduced the patients'
"hyperfrontality," as determined by the ratio between medial-frontal and
whole cerebral cortex blood flow, and significantly lowered ratings of
obsessive-compulsive and anxiety symptoms.
