Detaljeret beskrivelse
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
Tidsramme: 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.

Self-reported physical activity
Tidsramme: Baseline and monthly for the 6-month study period
|
Physical activity will be measured with the International Physical Activity Questionnaire-Short Form (IPAQ-SF).
This questionnaire will ask participants about their moderate and vigorous physical activity and time spent walking, to give a total sum score of Metabolic Equivalent of Task (MET).
Higher calculated (MET) scores indicate greater physical activity.

Physical Function
Tidsramme: Baseline and 6 months
|
Physical function will be measured using the PROMIS Physical Function-MS 15a.
This self-report questionnaire assesses participants' physical functioning and ability to perform everyday activities.
|
Baseline and 6 months

Diet Quality
Tidsramme: Baseline and monthly for the 6-month study period.
|
Diet will be measured using the Dietary Screener Questionnaire (DSQ), a self-report questionnaire that assesses the frequency of consumption of selected foods and beverages during the previous month to estimate intake of key dietary components, including fruits, vegetables, whole grains, dairy products, fiber, and added sugars.
The outcome measure will be the total DSQ-derived diet quality score.
