Title

Evaluation of transcranial magnetic stimulation efficiency in major depressive disorder patients: a magnetic resonance spectroscopy study

Overall design

This study evaluated the antidepressant effect of repetitive transcranial magnetic stimulation (rTMS) and examined how it affected N-asetyl aspartate, choline, creatine, lactate, myoinositol, glutamate, glutathione, and glutamine metabolite levels in the left dorsolateral prefrontal cortex (DLPFC) of major depressive disorder (MDD) patients who were not receiving antidepressant medication. Twenty-three MDD patients underwent H magnetic resonance spectroscopy before and within 3 days of completing TMS therapy. All patients completed 20 sessions of rTMS directed to the left DLPFC over a 2-week period. For metabolite quantification, the peak area was normalized by the total phosphorous signal. Eighteen patients were evaluated for the analysis.
