Key Takeaway

Donated brain tissue from people with MS and tissue from mice with an MS-like disease showed nerve cell loss and weaker energy activity.

What They Found

Donated tissue from people with MS showed loss of nerve cells that help control movement and coordination. This loss was especially noted in tissue from people with secondary progressive MS. The remaining tissue showed less activity in a process that helps cells make energy. Inflammation and damage to nerve coverings and nerve fibers were also present. Mice with a late-stage MS-like disease showed similar changes, along with other changes in how their cells made energy.

Who Should Care and Why

The researchers studied donated brain tissue from people with MS and mice with an MS-like disease. The findings were especially noted in tissue from people with secondary progressive MS. The study focused on a brain area involved in movement and coordination. This area can be affected in people with MS who have tremors or trouble coordinating movement. The similar changes in mice may make them useful for studying this brain damage.

Important Considerations

You cannot tell from this study whether lower cell energy activity caused the nerve cell loss. The human findings came from donated tissue after death, while the mouse findings came from an MS-like disease. The abstract does not give a sample size or report testing a treatment in people.

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.
