Practicing smartphone thinking tests reveals MS changes

Key Takeaway

When people with MS repeat a short smartphone thinking test, their scores improve at first (a practice effect) and the level they reach after that improvement (the plateau) better reflects disease-related brain and disability changes than a single test score.

What They Found

Researchers had people with MS and healthy people take a short phone-based thinking test many times over days and again after five years. Most people showed a quick rise in scores as they practiced, then reached a steady level (a plateau). People with poorer thinking at the start showed a larger percent increase when they practiced, but the final plateau score was similar across groups. The plateau score was more closely tied to disability and brain size than the very first test score. This means the early practice increase is tied to thinking ability, while the plateau may better show disease-related brain change.

Who Should Care and Why

People with MS and their caregivers should know that a single thinking test can be misleading if practice isn’t considered — scores often go up just from getting used to the test, like getting better at a video game the more you play. Using short, repeat phone tests and watching for the plateau gives a clearer picture of real thinking changes, similar to how repeated temperature checks show a fever pattern rather than one reading. Clinicians and therapists can use repeated tests to track whether thinking problems are stable, improving, or linked to disease changes, helping guide care and rehab. Caregivers can help by encouraging regular testing and noting if daily life tasks match the test results, for example if remembering names or following steps becomes harder despite steady test scores. This approach helps set realistic goals and avoid worrying over small score jumps that come just from practice.

Important Considerations

The study had more people with MS than healthy controls, so the comparison group was small and may not represent everyone. The phone test is similar to — but not exactly the same as — clinic tests, so results might differ from hospital-based assessments. These findings show links, not cause-and-effect, so changing treatment should not be based only on practice patterns without talking to your healthcare 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.
