The authors investigated whether there were differences in caudate and lenticular nucleus volumes in depressed patients relative to comparison subjects, and whether differences in basal ganglia volume were associated with treatment response to fluoxetine. Brain magnetic resonance images were obtained from 38 unipolar depressed patients and 20 matched(More)
We have investigated proton magnetic resonance spectra of the basal ganglia in 41 medication-free outpatients with major depression, prior to starting an 8-week standardized trial of open-label fluoxetine, and 22 matched comparison subjects. Upon completing the trial, depressed subjects were classified as treatment responders (n = 18) or nonresponders (n =(More)
Proton magnetic resonance spectra (MRS) were acquired from 1.5 x 1.5 x 1.5-cm voxels in the left and right mesial temporal lobes of 20 schizophrenic patients and 20 non-psychiatric comparison subjects. Choline (Cho) to creatine (and phosphocreatine) (Cr(PCr)) ratios were estimated as were the percent gray matter, white matter and CSF contributing to the(More)
The authors investigated whether there were differences in cerebral and cerebellar gray and white matter volumes in depressed patients compared to controls, and whether this was associated with treatment response to fluoxetine. Brain magnetic resonance images were obtained from 38 unipolar depressed patients and 20 age, gender, and educationally matched(More)
