Blood marker may flag MS worsening without relapses
Key Takeaway
A blood marker was linked to a higher risk of MS worsening without a relapse.
What They Found
Researchers measured a blood marker linked to support cells in the brain and spinal cord. Higher levels were linked to a greater risk of MS worsening without a relapse. This link appeared in two separate groups of people with MS. A different blood marker was linked to relapse risk within the next year. Among people taking certain MS treatments, falling levels of the first marker were linked to a lower risk of later worsening.
Who Should Care and Why
The study followed people with MS at specialist centers in Switzerland and the United States. It focused on worsening that happened without a relapse. That kind of worsening can be hard to predict for one person. The findings suggest this blood marker might help researchers identify people at higher risk. It might also help researchers track changes during treatment, but the study did not test that use in care.
Important Considerations
You should know this was an observational study of 2,329 people, so it cannot show that a treatment prevented worsening. You should also know the two groups used different measures of worsening. The abstract does not show whether using this blood marker improves your care.

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 JAMA neurology 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.
