An expert review offers guidance on telling MS from other conditions in children and older adults.
MS usually starts in early adulthood, but it can also begin in childhood or after age 50. The review focuses on these less common ages of onset. Children and older adults differ from younger adults in ways that may affect how MS appears. These differences may also affect which other conditions resemble MS. An international group of MS experts identified warning signs that may point to a condition other than MS.
This review concerns children under 18 and adults over 50 who may have MS. It also concerns the clinicians assessing them. MS starts before age 18 in 2% to 10% of cases. It starts after age 50 in about 5% of cases. The authors say these age groups need guidance tailored to their differences.
You should know this is expert guidance, not a study testing a diagnostic method. The abstract gives no number of people studied. It does not show how often the guidance leads to a correct diagnosis.

Read MoreWhether 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.
