Early signs and habits that affect MS disability

Key Takeaway

Early clinical signs and everyday lifestyle choices (like activity, weight, smoking, and sun exposure) help predict whether someone with relapsing MS will have stable or worsening disability over time.

What They Found

Researchers looked at 3,163 people newly diagnosed with relapsing MS and tracked their disability over years using a common disability score. They found seven different long-term patterns: the largest group stayed at low disability, while three groups showed steadily increasing disability and were labeled "unfavorable." People who were older at diagnosis, had symptoms for longer before diagnosis, had higher disability at the start, more relapses early on, worse thinking tests, or other autoimmune conditions were more likely to be in the unfavorable groups. Everyday factors mattered too: being obese, smoking, and spending little time in the sun were linked to worse outcomes, while being physically active lowered the chance of a worse course. Vitamin D measured at diagnosis did not show a clear link to long-term disability in this study.

Who Should Care and Why

People with relapsing MS and their caregivers should care because the study points to early signs and habits that relate to long-term disability, which can help with planning and care choices. Doctors and MS care teams can use this kind of information to tailor monitoring and treatments earlier for people at higher risk—like stepping up rehab or checking lifestyle supports sooner. Someone who smokes, is inactive, or has obesity might compare their situation to a small leak in a boat: fixing it early (quitting smoking, gaining fitness, losing weight) might help prevent bigger problems later. Caregivers can use this to prioritize daily supports that encourage activity, sun-safe outdoor time, and help with quitting smoking or weight management. This information is most useful right after diagnosis, when small changes and medical decisions may have bigger long-term effects.

Important Considerations

This study shows links but cannot prove that changing a habit will definitely change your MS course; it observes associations, not direct cause and effect. The results come from people in Sweden and from clinic records, so findings might differ in other places or groups. Also, not every person fits the same pattern—individual outcomes vary—so discuss personal risks and actions with your MS care team.

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 Journal of 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.
