New lab method finds differences between progressive MS brains
Key Takeaway
A new lab method found differences between donated MS brains that were greater than differences between types of MS lesions.
What They Found
Researchers studied 156 donated brain tissue samples from people with MS and people without MS. They used a lab method that shows which genes are active in individual cells. In MS tissue, cells in gray matter showed different changes from cells in white matter. Different types of MS lesions contained different mixes of cells, but similar patterns of gene activity. Most differences in gene activity were linked to the donor, which helped researchers group people by changes in their brain tissue.
Who Should Care and Why
This lab study used donated brain tissue from people with MS and people without MS. The researchers aimed to better understand differences among people with progressive MS. Their findings suggest that changes in brain tissue may differ more between people than between types of lesions. The study examined tissue after donation, not tests used in routine MS care. The researchers described matching brain findings with blood or spinal fluid findings as a future step.
Important Considerations
The study examined 156 brain tissue samples, but the abstract does not give the number of donors. It did not test a treatment. It also did not show whether blood or spinal fluid tests can identify these differences in people living with MS.

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 Neuron 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.
