Non-invasive brain stimulation for multiple sclerosis fatigue

Non-invasive Brain Stimulation for Altering Neuro-inflammatory Mediators of Central Fatigue in Multiple Sclerosis

NA · Charite University, Berlin, Germany · NCT07438964

What this trial studies

This randomized interventional study enrolls adults with relapsing-remitting MS with and without central fatigue and applies either true or sham anodal transcranial direct current stimulation (tDCS) to the left dorsolateral prefrontal cortex on five consecutive daily visits (V1–V5). Participants undergo fMRI, blood-based proteomics, and clinical measures at baseline and after the five stimulation sessions, with additional questionnaire follow-ups at two and four weeks (V6, V7). The design compares changes in reward-related brain activity, inflammatory markers, and fatigue scores between groups and stimulation arms. Primary and secondary outcomes are assessed at V1 and V5.

Who should consider this trial

Good fit: Ideal candidates are adults 18–70 with relapsing-remitting MS (EDSS ≤4, disease duration ≤10 years), insured, on stable or no disease-modifying treatment for at least six months, able to undergo MRI, and able to attend five consecutive study visits, with fatigue status defined by FSMC score.

Not a fit: People with progressive MS, higher disability (EDSS >4), recent relapse or steroid treatment, MRI contraindications, or current use of excluded monoaminergic medications or incompatible DMTs are unlikely to be eligible or to benefit.

Why it matters

Potential benefit: If successful, this approach could reduce central fatigue and provide a non-drug treatment option to improve daily functioning for people with relapsing-remitting MS.

How similar studies have performed: Small prior trials of tDCS for MS fatigue have produced mixed but sometimes promising symptom reductions, while combining fMRI and proteomics to study reward-related mechanisms is relatively novel.
