Brain shrinkage in MS: new study aims to compare treatment effectiveness
NCT ID NCT05962177
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study follows 400 people with relapsing-remitting multiple sclerosis to see how their brains change over three years. Researchers will use MRI scans and blood tests to compare those on high-efficacy treatments versus medium-efficacy ones. The goal is to understand which treatments better slow brain atrophy, a key sign of disease progression.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors choose better treatments to slow brain shrinkage in multiple sclerosis patients.
- What could go wrong
- This is an observational study, not a treatment trial. It will not directly test a new drug or cure, and results may not change care immediately.
This is an AI summary of the original study and may miss details. Read our disclaimer.
