Pilot Study of Transcranial Direct Current Stimulation (tDCS)
In Brief
A clinical study evaluating Transcranial Direct Current Stimulation (tDCS), Sham Transcranial Direct Current Stimulation, and 1 other intervention for Multiple Sclerosis. Completed, enrolled 31 participants across 1 site.
Detailed Summary
This study will test the tolerability and preliminary efficacy of transcranial direct current stimulation (tDCS) combined with a cognitive training program, remotely-delivered using a telemedicine protocol in 60 adults with multiple sclerosis (MS). The study will evaluate the efficacy of tDCS to evaluate two of the most debilitating symptoms of MS: cognitive impairment and fatigue.

Timeline
Interventions
tDCS is a therapeutic development that utilizes low amplitude direct currents to induce changes in cortical excitability. tDCS is expected to produce neuronal polarization of less than one mV (millivolt) 9. tDCS produces relatively diffuse current flow, as demonstrated by imaging studies and computational models
During a sham session, the device is programmed to ramp up to the desired intensity (target 2.0 mA) and ramp down for the initial 60 seconds, with no current delivery during the session, and then again at the end of the session. These brief periods of stimulation serve to mimic the effects of a true stimulation session.
