Effect of Theta-burst rTMS Therapy on the Clinical and Cognitive Symptoms of Patients With Therapy Resistant Depression and Response Prediction With Neuroimaging Methods.

Theta-burst rTMS treatment stimulates the left Dorsolateral Prefrontal Cortex (DLPFC). The TBS parameters the investigators adopted follows the standard TBS protocols, with 3-pulse 50-Hz bursts given every 200 ms (at 5 Hz) and an intensity of 100% active motor threshold. The investigators plan to deliver 1800 stimuli to the left DLPFC daily in 9.5-minute blocks for four weeks.
