Scans found signs of nerve connection loss in MS and mice
Key Takeaway
Brain scans found signs of fewer connections between nerve cells in people with MS and in mice with an MS-like disease.
What They Found
Researchers used a brain scan to look for signs of connections between nerve cells. In mice with an MS-like disease, the scan signal was nearly 30% lower across the brain regions studied. Other lab tests supported the mouse scan findings and found lower levels of the same marker in the spinal cord. In people with MS, the scan signal was about 16% lower across the brain’s outer layer than in people without MS. Several brain areas showed reductions of about 16% to 26%.
Who Should Care and Why
The study included mice with an MS-like disease and people with and without MS. The people with MS were compared with people without MS of similar ages. The researchers studied a scan that may help measure the loss of connections between nerve cells. They found similar patterns of loss in the mice and the people with MS. The human results came from a small early study.
Important Considerations
You should know the human study compared 6 people with MS and 6 people without MS. It did not test a treatment. The abstract does not say whether these scan results can predict changes in your symptoms or disability.

Read MoreUnderstanding MS Research
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 Proceedings of the National Academy of Sciences of the United States of America 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.
