Brief Summary
Notwithstanding the cumulative evidence on the safety and efficacy of transcranial magnetic stimulation in depression care, the non-response rate to transcranial magnetic stimulation (TMS) amongst treatment-resistant depression has remained substantial despite the health care cost and time incurred. There remains a compelling clinical need to find valid biomarkers to inform personalized treatment. Using supervised machine learning on 4 combined features of neuroimaging markers, our group recently reported excellent prediction for clinical response in 70 patients receiving TMS to left dorsolateral prefrontal cortex for medication-resistant major depression in 2015-18 (Phase 1 study).The clinical utility of these potential neuroimaging biomarkers is still uncertain without further validation of the trained model in an independent clinical cohort.

Outcome Measures
Primary Outcomes (4)
Montgomery-Ashberg Depression Rating Scale
Questionnaire used to measure the severity of depressive symptoms and treatment response in patients with mood disorders consisting of 10 items. The score range is 0-60 and higher score indicates more severe depression.

rTMS Group
EXPERIMENTALPhase I: A Magstim Super-Rapid device with a 70-mm figure-of-eight double air film coil (Magstim Ltd, UK) and Brainsight neuronavigation (Rogue Resolutions Ltd, Canada) are used. Stimulation parameters: 10 Hz, 120% resting motor threshold, 30 trains of 5 seconds with 25 seconds rest, 3000 pulses per day delivered 5 days per week (total: 60000 pulses). Phase II: MagVita X100 (FDA approved device) will be used to deliver intermittent theta burst stimulation (iTBS) to left DLPFC, comprising of 18 cycles of 10 bursts. Each burst is triplet of pulses discharged at 50 hz and the burst frequency is 5Hz. Between two cycles of bursts is 8-second inter-train rest. The device output is set at 120% above the resting motor threshold
