Early blood test linked to later MS disability worsening
Key Takeaway
Higher levels of a blood marker after a first MS-like attack were linked to greater disability worsening years later.
What They Found
Researchers measured a blood marker of nerve damage within the first year after a first MS-like attack. People with higher levels were more likely to have disability that worsened and stayed worse for six months. They were also more likely to reach a higher level of disability on a doctor's rating scale. The link appeared in both groups of patients studied at Spanish hospitals. Among people with high marker levels, stronger MS treatments were linked to a lower risk of disability worsening.
Who Should Care and Why
The study followed people in Spain after their first MS-like attack. It focused on whether an early blood test could help predict later disability. Researchers checked patients at least every six months. They followed patients for about seven years, on average. The findings may help identify people at greater risk of disability worsening, but the test's role in treatment decisions remains uncertain.
Important Considerations
This observational study followed 578 people and did not assign treatments. You cannot tell from these findings whether stronger MS treatments caused the lower risks seen among people who received them. The study does not show whether using this blood test to choose treatment improves outcomes.

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.
