Home-Based Transcranial Direct Current Stimulation (tDCS) for Depression in Multiple Sclerosis (MS)

tDCS is a noninvasive brain stimulation technique that delivers a low-intensity electrical current (2.0 mA) through sponge electrodes placed on the scalp. For Active tDCS, the device is programmed to ramp up to 2.0 mA (for 30 seconds), provide constant current throughout session (29 minutes), and then ramp down (for 30 seconds) at the end.

tDCS is a noninvasive brain stimulation technique that delivers a low-intensity electrical current (2.0 mA) through sponge electrodes placed on the scalp. For Sham tDCS (or placebo) the device is programmed to ramp up to 2.0 mA (for 30 seconds) followed by a ramp down (30 seconds), with no current delivery for 28 minutes, and then ramp up (for 30-s) and down (for 30-s) at the end.
