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.
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 the…
