Overview
Brief Summary
This study evaluates a schedule of precise repetitive transcranial magnetic stimulation for depressive adolescent with anhedonia. In this randomized controlled trial, half of the participants will receive repetitive transcranial magnetic stimulation, and the other will receive sham stimulation.
Detailed Description
Repetitive transcranial magnetic stimulation (rTMS) is an established technology as therapy for treatment-resistant depression among adult. The approved method for treatment is 10Hz stimulation over the left dorsolateral prefrontal cortex (L-DLPFC). This methodology has been successful for many people with treatment-resistant depression. However, a large percentage of adolescents suffering from major depressive disorder (MDD) do not adequately benefit from currently available treatments. One of the limitations is concerns about the safety and efficacy of antidepressant. Recently, researchers have aggressively pursued better treatment strategy such as rTMS to improve adolescent depression with some preliminary success. This study intends to further explore the safety and efficacy of rTMS in the treatment for adolescent major depressive disorder with anhedonia. This study will also look at the change in neuroimaging biomarkers associated with this treatment.
