Study Arms:
- Sham stimulation / sertraline (Type: EXPERIMENTAL): In this arm, patients will receive sham stimulation and sertraline 50mg/day. In sham stimulation, the tDCS device is set in the same fashion as the active stimulation, but the device is turned off after one minute of stimulation.
- Sham stimulation / placebo pill (Type: SHAM_COMPARATOR): Placebo pills are sugar pills having the same size and shape of the active pills.~In sham stimulation, the tDCS device is set in the same fashion as the active stimulation, but the device is turned off after one minute of stimulation.
- Active stimulation / Sertraline (Type: EXPERIMENTAL): In active stimulation, the anode is placed over the left dorsolateral prefrontal cortex and the cathode is placed over the right prefrontal cortex. They are located five centimeters ventrally of the primary motor area, which are located five centimeters laterally of the central point of the scalp (which is located on the intersection of the sagittal and median curves). The device will deliver a charge of 2mA for 30 minutes.~Patients will receive Sertraline 50mg/day.
- Active stimulation / placebo pill (Type: EXPERIMENTAL): In active stimulation, the anode is placed over the left dorsolateral prefrontal cortex and the cathode is placed over the right prefrontal cortex. They are located five centimeters ventrally of the primary motor area, which are located five centimeters laterally of the central point of the scalp (which is located on the intersection of the sagittal and median curves). The device will deliver a charge of 2mA for 30 minutes.~Placebo pills are sugar pills having the same size and shape of the active pill
