    Sham (Placebo)

    		Participants will receive up to 30 sham rTMS sessions within the 8-week treatment period.
  • Device: Sham (Placebo)

    Each sham rTMS session will consist of 75 rTMS trains of 10 Hz for 4 seconds (40 pulses per train) with inter-train interval (ITI) of 11 seconds (a total of 3000 stimuli per session) over the left dorsolateral prefrontal cortex (DLPFC). In the placebo condition the magnetic field will be delivered in the opposite direction (away from the brain).
