Empower: tDCS for Major Depressive Disorder at Home

Transcranial direct current stimulation (tDCS) a non-invasive brain stimulation technique where a weak direct current (2 mA) is applied on the scalp through electrodes. The current modulates the underlying neural activity. The sessions are 30 minutes, 3-5 time a week.

To blind the participants of the stimulation, a standardized sham protocol is used where the current ramped up and then down breifly in the beginning and end of each session to simulate active stimulation.
