Multiple sclerosis (MS) is the most common progressive disease of the central nervous system in young adults and the cause of serious physical disability in adults of working age. Epidemiologic data suggest that rates of MS vary with demographic and environmental factors. The disease presentation is very heterogeneous with diverse clinical manifestations. Progression of MS may vary with modifiable risk factors.
This systematic review focused on modifiable risk factors and exposures that are associated with MS progression, and interventions that are directed at modifiable risk factors to delay progression.
The Key Questions (KQs) were:
KQ1: What modifiable epidemiologic factors are related to multiple sclerosis progression following diagnosis?
KQ2: What environmental exposures prior to or during military service are related to multiple sclerosis progression following onset symptoms?
KQ3: Among identified risk factors for progression, what treatment/risk factor modification therapies have been shown to delay or hasten the progression of multiple sclerosis once it has initiated?
