About the study
The purpose of the study is to test whether low level electric stimulation, called transcranial Direct Current Stimulation (tDCS), on the part of the brain (i.e., presupplementary motor area) thought to aid in memory will improve verbal retrieval in multiple sclerosis patients. The primary outcome measures are neuropsychological assessments of verbal retrieval, and the secondary measures are neuropsychological assessments of other cognitive abilities and electroencephalography (EEG) measures. Additionally, the study will examine the degree to which baseline assessments of cognition and concussion history predict responses to treatment over time, both on assessments administered within the intervention period and at follow-up.
