At what age range does multiple sclerosis most commonly strike?

Multiple sclerosis (MS) most commonly manifests in young to middle-aged adults, typically between the ages of 15 and 60. This range captures the peak onset age for MS, with a significant proportion of individuals experiencing their first symptoms between the ages of 20 and 40.

The age range of 15-60 years encompasses both the early adult years when many individuals are establishing their careers and personal lives, as well as the early stages of life transitions that can coincide with the onset of autoimmune diseases like MS. This information aligns well with clinical studies and epidemiological data that show a higher prevalence of MS among individuals in this age group.

In contrast, the other age ranges provided would either suggest the onset of the disease in childhood, which is atypical for MS, or include ages that extend well into or beyond the majority of typical onset cases. Therefore, focusing on the specified age range of 15 to 60 years effectively captures the demographic where MS is most prevalent.
