Frailty in Multiple Sclerosis: A Scoping Review of Prevalence, Clinical Associations, and Outcomes
This systematic scoping review identified 11 studies examining frailty in people with multiple sclerosis, finding frailty prevalence ranges from 17–66% with early onset compared to the general population. Higher disability levels, longer disease duration, and progressive MS subtypes were consistently associated with frailty, which also correlated with reduced walking performance, poor sleep quality, fatigue, and lower quality of life.
