This review describes how MS disability can worsen without relapses, even early in the disease.
More than 2.8 million people worldwide are estimated to have MS. MS is becoming more common, and more people are developing it each year. Recent estimates suggest MS is most common among people in their 50s. The review describes evidence that disability can worsen without a relapse, even early in MS. It also explains that studies define this kind of worsening in different ways.
This review discusses people with MS, rather than reporting on a new group of participants. It covers changing patterns of MS in Europe and estimates of MS worldwide. It is relevant to people whose disability worsens without a relapse. The authors describe relapses and gradual worsening as features that can overlap from early in MS. They discuss whether this overlap may change how doctors describe the course of MS.
You should know this is a review, not a study testing a treatment. It does not give a participant count or show how often disability worsens without relapses. Because studies define that worsening differently, its role in MS remains uncertain.

Studies published in respected medical journals like The Lancet regional health. Europe 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.
