New lab images find a virus in progressive MS brains
Key Takeaway
A new lab imaging method found signs of the Epstein-Barr virus in damaged areas of brains with progressive MS.
What They Found
Researchers used a lab imaging method to examine brain tissue affected by progressive MS. They found more signs of the Epstein-Barr virus in MS lesions (areas of tissue damage) than in nearby tissue that looked normal. Cells with signs of the virus were close to nerve cells and other brain cells. The images also showed changes in how immune cells and brain cells were grouped together. Some areas showed damage to the barrier that helps keep harmful substances out of the brain.
Who Should Care and Why
The study examined brain tissue from people with secondary progressive or primary progressive MS. It focused on damaged areas and nearby tissue that looked normal. It may interest people following research on why progressive MS causes damage. The images show where signs of the virus appeared in the tissue. They do not show whether the virus caused the damage.
Important Considerations
You should know this was a study of brain tissue from two separate groups; the abstract does not give a sample size. You cannot tell from these images whether the virus caused the damage. You cannot tell whether antiviral drugs would help, because the researchers did not test them.

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.
