TBS Treatment for Treatment-Resistant Depression

3 TBS sessions per day, with an offer of 1200 pulses per session and a 30-minute interval between sessions. This protocol will be applied to patients for 15 days, totaling 45 stimulation sessions. The stimulations will be directed to the left dorsolateral prefrontal cortex (F3 obtained by the Beam method) and will be performed in a Magventure MagPro R30 device.The stimulation will be delivered at 100% of the motor threshold and will last for 6 minutes.

The placebo will consist of a sham stimulation activity. A noise generator, which makes the same noise as active stimulation, and a surface electrode placed over the patient's eyebrow, mimicking the tactile sensory effects of TBS. It will also occur three times a day, with a duration of 6 minutes. The interval time between procedures will be of 30 minutes. It will take place for the same 15 weekdays, totalizing 45 sham stimulations.
