Brief Summary
Major depression (or MDD) in adolescents is a major public health problem. MDD affects approximately 15% of adolescents; it is associated with impairment in social, family, and academic functioning, and it is a major risk factor for suicide - a leading cause of death in adolescents . Unfortunately, there is a paucity of treatment options for this age group. Selective serotonin reuptake inhibitors (SSRIs) are the only class of medications approved for treating MDD in adolescents, but rates of remission following treatment with SSRIs are only 30 to 45 percent. Cognitive behavior therapy is associated with similar remission rates and access is limited. Most adolescents will require more than one therapeutic intervention in order to achieve full symptom control. Collectively, there is overwhelming evidence that additional treatment options are urgently needed to improve outcomes for teens with MDD. One novel treatment for adolescent MDD is repetitive transcranial magnetic stimulation (rTMS). Studies in children have been limited (a total of 23 cases). This is surprising given the evidence suggesting younger adult subjects with MDD respond better to rTMS (56% response rate) than older subjects. This limited experience with rTMS for adolescent MDD represents a substantial gap in the knowledge, recently recognized in publications calling for further study of rTMS in adolescent depression. Most importantly, the mechanism of action of rTMS in adolescent MDD is not well understood. The objective of this application is to develop an understanding of the brain alterations associated with the positive clinical changes that occur with rTMS in adolescent MDD. Such knowledge will provide the basis for pursuing rTMS for adolescent MDD as a rational therapeutic technique. Specific Aim: To compare the effect of rTMS on DLPFC glutamate concentration in adolescent MDD. The investigators hypothesize an increase (normalization to controls) in DLPFC glutamate after three weeks of rTMS. Furthermore, the change in glutamate concentration will correlate with a change in MDD symptoms.

Study Arms (1)
Transcranial Magnetic Stimulation
EXPERIMENTALThe standardized treatment location will be the left DLPFC. Anatomical T1 images from the pre-intervention MRI will be loaded into our Transcranial Magnetic Stimulation (TMS) lab neuronavigation software (Brainsight2, Rogue Research, Montreal). Following 3D co-registration of the TMS coil with the patient's MRI images and head, the coil will be placed over the left DLPFC (tangential to scalp, angle of 45 degrees to midline). Interventional repetitive TMS (rTMS) (Magstim Rapid2, Wales, UK) will consist of 40 suprathreshold (120% RMT) pulses over 4 seconds (10 Hz) with an inter-train interval of 26 seconds. Treatment sessions will last 37.5 minutes (75 trains/3000 pulses). Treatments will occur on each weekday for three weeks (15 days total).

Eligibility Criteria
You may qualify if:
- age (12-22 years),
- MDD failing to respond to at least one SSRI trial (minimum 8 weeks treatment at an adequate dose; determined retrospectively), and
- informed consent. Healthy controls with no psychiatric history (who do not receive rTMS) will undergo MRI scans to allow for comparison with MDD patients.
You may not qualify if:
- previous seizures or epilepsy,
- hypertension,
- additional neurological or psychiatric diagnoses (specifically: bipolar disorder, psychosis, pervasive developmental disorder, eating disorders, and post-traumatic stress disorder).
