What this trial studies

This study aims to evaluate the effectiveness of transcranial Direct Current Stimulation (tDCS) on enhancing verbal retrieval and cognitive functions in patients with relapsing-remitting multiple sclerosis. Participants will be randomly assigned to receive either active tDCS or sham treatment over ten sessions, with assessments conducted before, immediately after, and two months following the intervention. The study will also explore how baseline cognitive assessments and concussion history may influence treatment outcomes. By comparing the two treatment arms, the research seeks to determine the potential benefits of tDCS in addressing cognitive deficits associated with multiple sclerosis.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with relapsing-remitting multiple sclerosis who exhibit memory retrieval deficits.

Not a fit: Patients with acute MS exacerbations, severe neurological disorders, or those unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve memory retrieval and cognitive function in patients with multiple sclerosis.

How similar studies have performed: While the use of tDCS in cognitive rehabilitation is gaining interest, this specific application in multiple sclerosis is relatively novel and has not been extensively tested.
