Brief 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.

Condition or disease Intervention/treatment Phase
Multiple Sclerosis Device: Transcranial Direct Current Stimulation (tDCS) Device: Sham Transcranial Direct Current Stimulation Behavioral: Cognitive Training Program Phase 3

Detailed Description:

Transcranial direct current stimulation (tDCS) has been demonstrated to:

  1. successfully treat fatigue in adults with MS, and
  2. improve learning ability and other aspects of cognitive functioning in healthy controls and in participants with a range of medical disorders.

Cognitive impairment in MS remains a major treatment challenge and a trial of tDCS combined with a cognitive training program to treat MS-related cognitive impairment is warranted. However, one barrier for the study of tDCS has been the need for the participant to travel to the study site for each tDCS administration. To address this issue, the biomedical company Soterix, has recently designed a remote-delivery tDCS device designed for use in clinical trials. Therefore, the primary goal of this study is to establish a protocol for remotely-supervised in-home tDCS delivery for studies with MS participants. Established safety and feasibility of remotely-supervised tDCS delivery will facilitate the next steps of larger controlled trials, in both MS as well as other conditions, to determine efficacy and appropriate real-world use.

Arm Intervention/treatment
Active Comparator: Transcranial Direct Current Stimulation (tDCS) Device: Transcranial Direct Current Stimulation (tDCS)
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
Other Name: Soterix 1x1 tDCS mini-CT

Behavioral: Cognitive Training Program
Sham Comparator: Sham Transcranial Direct Current Stimulation (tDCS) Device: Sham Transcranial Direct Current Stimulation
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.

Behavioral: Cognitive Training Program



Primary Outcome Measures :
  1. The number of participants completing at least 80% of the targeted sections [ Time Frame: Four Weeks ]
    80% is equivalent to n=16 of the targeted 20 sessions

  2. Total score of the Brief International Assessment of Cognition in MS (BICAMS) [ Time Frame: Four Weeks ]

Secondary Outcome Measures :
  1. Comparisons between the active and sham conditions on Fatigue Impact Scale [ Time Frame: 4 Weeks ]
  2. comparisons between the active and sham conditions on measure Cognitive State Brief Battery Score [ Time Frame: 4 Week ]
