Brain changes in post-COVID fatigue overlap with MS
Key Takeaway
People with lasting fatigue after COVID-19 had brain changes that overlapped with changes seen in people with MS.
What They Found
Brain scans showed changes in areas involved in movement and thinking among people with lasting fatigue after COVID-19. Some changes overlapped with more widespread changes seen in people with MS and fatigue. Certain scan findings were linked to worse fatigue, daytime sleepiness, and trouble with daily life. Changes in brain shape and size were linked to poorer short-term memory. Worse sleep and more signs of depression were linked to worse fatigue, but the severity of the earlier COVID-19 illness was not.
Who Should Care and Why
The study compared people with lasting symptoms after COVID-19, people with MS and fatigue, and healthy volunteers. The MS group served as a comparison, not as the main group being studied. The overlap in brain scans may interest people with MS who experience fatigue. The study also examined memory, sleep, and mood in the post-COVID group. Its findings about what was linked to fatigue came from people after COVID-19, not from the MS group.
Important Considerations
You should know this was an observational study, so it cannot show that brain changes caused fatigue. Researchers recruited 50 people after COVID-19 and included 47 people with MS and fatigue. The abstract does not give the number of healthy volunteers, so the full study size is unclear.

Whether you’ve recently been diagnosed with Multiple Sclerosis (MS) or are seeking to broaden your understanding of this complex, neurodegenerative disease, navigating the latest research can feel overwhelming. Studies published in respected medical journals like EClinicalMedicine often range from early-stage, exploratory work to advanced clinical trials. These evidence-based findings help shape new disease-modifying therapies, guide symptom management techniques, and deepen our knowledge of MS progression.
However, not all research is created equal. Some clinical research studies may have smaller sample sizes, evolving methodologies, or limitations that warrant careful interpretation. For a more comprehensive, accurate understanding, we recommend reviewing the original source material—accessible via the More Details section above—and consulting with healthcare professionals who specialize in MS care.
By presenting a wide range of MS-focused studies—spanning cutting-edge treatments, emerging therapies, and established best practices—we aim to empower patients, caregivers, and clinicians to stay informed and make well-informed decisions when managing Multiple Sclerosis.
