Combating Age-related Failure of Myelination in Multiple Sclerosis: An Exploratory Study (MAPMyeMS)

20 lipca 2026 zaktualizowane przez: Sarah Simmons, MD, PhD, University of Washington

Combating Age-related Failure of Myelination in Multiple Sclerosis: an Exploratory Study

This observational, longitudinal study will examine whether physical activity and other potentially modifiable lifestyle factors are associated with changes in myelin, the protective coating around nerve fibers, in older adults with multiple sclerosis (MS). Participants will undergo magnetic resonance imaging (MRI) scans to measure myelin throughout the central nervous system and will wear wrist-worn activity trackers to assess physical activity over time.

Szczegółowy opis

The primary aim of this study is to explore clinical variables and potentially modifiable risk factors that are associated with improved myelination (both enhanced remyelination and reduced demyelination) in older adults living with multiple sclerosis. The emphasis here will be on discovery and generation of pilot data to support further definitive longitudinal observational studies, and ultimately, clinical trials on behavioral and/or pharmaceutical interventions to prevent demyelination and promote remyelination in people living with MS.

Participants will be categorized based on whether they meet or exceed the current physical activity guidelines of at least 150 minutes per week of moderate-intensity aerobic physical activity, 75 minutes per week of vigorous-intensity aerobic physical activity, or an equivalent combination.

At both baseline and 6 months, MRI and clinical assessments will be obtained, and chart review will be performed. Participants will wear a wrist-worn physical activity monitor and answer monthly questionnaires (assessed via REDCap survey) throughout the study period.

Linear regression will be performed to estimate the effect size of various physical activity variables (step count, sedentary time, and time spent in light/moderate/vigorous physical activity, aerobic capacity and overall strength) with 6-month change in myelination.

Quantitative MRI-derived myelin measure
Ramy czasowe: Baseline and 6 months
Change in MRI-derived measures of myelin content within the central nervous system. Specifically, the investigators will use macromolecular proton fraction (MPF), a quantitative MRI parameter which describes the magnetization transfer effect and defined as the relative amount of protons bound to biological macromolecules with restricted molecular motion.
