Phone Tests Spot MS Inflammation Earlier

Key Takeaway

Weekly smartphone tests of thinking speed and walking picked up changes linked to brain inflammation in people with relapsing-remitting MS, sometimes even before it showed on MRI.

What They Found

Researchers asked 57 people with relapsing-remitting MS to do two short smartphone tests each week for a year: a thinking-speed test (sSDMT) and a 2-minute walking test (s2MWT).When MRI scans showed active inflammation in the brain (contrast-enhancing lesions), scores on both smartphone tests tended to get worse — meaning slower thinking and shorter or slower walking.The thinking-speed phone test (sSDMT) was particularly sensitive to those MRI changes and even showed signs of change up to about six weeks before the MRI in some people.The walking phone test (s2MWT) also tracked MRI changes, but its signal came from both differences between different people and changes within the same person over time.Standard clinic tests (like the timed 25-foot walk, a paper-based thinking test, a hand dexterity test, and the overall disability score) also got worse when MRI showed inflammation, supporting that the phone tests are measuring meaningful change.

Who Should Care and Why

People with relapsing-remitting MS and their caregivers should care because simple weekly phone tests might give extra, early clues about a flare of inflammation — like a warning light before a problem gets worse.These smartphone checks can be done at home and are quick, so they could help you track changes between clinic visits without needing special equipment.Doctors and MS care teams can use this information to spot subtle changes sooner and decide if an earlier visit, MRI, or treatment change is needed — like noticing your car pulling before it stalls.Caregivers who help with daily routines can use regular test results to notice patterns (worse thinking or walking) and support timely conversations with the care team.People who value keeping a close eye on their MS activity — for example, those recently starting or changing treatment — may benefit most, because early detection can guide faster action.

Important Considerations

The study included 57 people, which is helpful but still a small group; results may look different in larger or more diverse groups.Not every change on the phone tests means a new inflammation flare — other things like tiredness, sleep, infections, or mood can affect thinking and walking too.Smartphone tests are not a replacement for medical care or MRI; they are a helpful extra tool that should be discussed with your doctor before changing treatments or skipping scans.

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.
