Sham Comparator
active iTBS
sham iTBS
Participants will receive 10 to 30 sessions of active intermittent theta burst stimulation (iTBS) consisting in delivering 2 s train of bursts containing three pulses at 50 Hz repeated each 200 ms every 10 s (iTBS). Each iTBS session contained 990 pulses and lasted 6 min. Stimulation intensity will be set at 80% of the patient's resting motor threshold. iTBS will be applied twice per day, with at least three hours between each session. Ten to 30 sessions will be delivered until patient achieved remission (i.e., 13-item Beck Depression Inventory (BDI13) score < 10). iTBS will be applied over the left dorsolateral prefrontal cortex (DLPFC) according to the individual's 3D-T1 MRI.
The same protocol (location, intensity, parameters of stimulation) will be applied using a commercial sham coil.
