Title

Effects of the antidepressant medication duloxetine on brain metabolites in persistent depressive disorder: a randomized, controlled trial

Overall design

The aim of this study was to assess whether patients with persistent depressive disorder (PDD) have abnormal levels of N-acetyl-aspartate and whether those levels normalize following treatment with the antidepressant medication duloxetine. The authors acquired proton magnetic resonance spectroscopic imaging (MRSI) data on a 3 Tesla, GE Magnetic Resonance Imaging scanner in 41 patients with PDD (PDD group) at two time points: baseline and at the end of a 10-week, placebo-controlled, double-blind, randomized controlled trial of the antidepressant medication duloxetine. Patients were randomized such that 21 patients received the active medication (PDD + duloxetine group) and 20 patients received placebo. In addition, the authors acquired MRSI data once in 29 healthy controls (control group). Metabolite quantification was normalized by background noise.
