Repetitive Transcranial Magnetic Stimulation Compared or Associated With Venlafaxine for Depressive Disorder

Repetitive Transcranial Magnetic Stimulation (rTMS) Compared or Associated With Venlafaxine for Depressive Disorder: A Functional Magnetic Resonance Imaging (fMRI) Study

The purpose of this study is to treat participants with a diagnosis of depressive disorder to assess the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) and venlafaxine in the treatment of depressive disorders compared venlafaxine only (the optimal medication) and to rTMS only. fMRI will be performed to determine if treatment response is related to changes in fMRI, and use it to investigate the respondence to the treatments.
