Summary

Repetitive transcranial magnetic stimulation (rTMS) and Theta burst stimulation (TBS) are approved by the US. Food and Drug administration (FDA) for the treatment of refractory major depression. TBS is more efficient than rTMS as it requires shorter stimulation time.Studies suggest that the efficacy of TBS could be enhanced and expedited by accelerated protocols (more than once daily sessions) with higher doses of stimulation (\>600 TBS pulses up to 3600 pulses per session) and shorter duration of treatment (4-10days). The main objective of this study is to determine the clinical efficacy and safety of accelerated high dose bilateral TBS treatment for patients with treatment resistant depression in comparison to sham stimulation using a randomized double blind clinical trial design.

DEVICE

Sequential bilateral theta burst stimulation

Three sessions of active or sham bilateral TBS will be delivered daily for 10 days in 2 weeks (no session on weekend) with a total of 30 sessions for each patient. Daily low intensity (90% resting motor threshold) bilateral sequential continousTBS ( cTBI) will be applied first on the right DLPFC (1800 pulses) and then intermittent TBS (iTBS)on the left DLPFC (1800 pulses) with an intersession interval of 60 minutes. We will adopt 1800 pulse per session based on the previous studies. Patients will receive a stimulation of 3600 pulses a session, 10,800 pulses a day and 108,000 pulses in total. After the study, sham group will receive active stimulation following the same protocol
