Quick Summary
This review examines how multiple sclerosis (MS) and ME/CFS are similar, particularly in how they cause fatigue and affect sleep. Both conditions involve damage to similar brain regions and may share genetic risk factors. The authors discuss how treatments like supervised exercise can help manage fatigue in both illnesses, though the underlying causes differ.
Why It Matters
Understanding the biological similarities between MS and ME/CFS could improve diagnosis and treatment of ME/CFS, a condition often poorly understood and undertreated. Identifying shared genetic and neuroimaging markers may accelerate research into ME/CFS mechanisms. The discussion of effective fatigue management strategies provides evidence-based options for patients managing persistent fatigue.
Observed Findings
Similar neuroimaging abnormalities in prefrontal cortex and basal ganglia in both MS and ME/CFS populations.
Genetic factors implicate shared susceptibility loci between MS and ME/CFS.
MS and ME/CFS can coexist in the same patients.
Sleep disorders, particularly restless legs syndrome, frequently occur in MS.
Supervised physical activity and moderate-intensity exercise showed improved outcomes for fatigue management.
Inferred Conclusions
Fatigue in MS and ME/CFS may involve overlapping brain regions and genetic mechanisms, despite differences in underlying pathophysiology.
Multiple sclerosis and ME/CFS warrant screening for comorbid conditions given their potential co-occurrence.
Therapeutic approaches should be individualized based on the specific underlying factors contributing to fatigue in each patient.
Moderate-intensity supervised exercise may represent an effective management strategy for fatigue across both conditions.
Remaining Questions
What are the specific genetic variants shared between MS and ME/CFS, and do they indicate common pathogenic mechanisms?
What This Study Does Not Prove
This narrative review does not establish causal mechanisms or definitive diagnostic criteria distinguishing MS from ME/CFS. It does not prove that genetic overlaps indicate identical disease pathophysiology, nor does it establish that exercise interventions work equally well across both conditions. The correlation of neuroimaging findings does not confirm they cause fatigue in the same way in both diseases.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
How frequently do MS and ME/CFS coexist, and what diagnostic criteria distinguish them when both are present?
Why do similar brain regions show abnormalities in both conditions despite different disease etiologies?
What mechanisms explain why moderate-intensity exercise helps some patients with ME/CFS-related fatigue while potentially worsening symptoms in others?
