What is the primary demographic that Multiple Sclerosis typically affects?

Multiple Sclerosis (MS) primarily affects adults aged 20-40. This age range is critical because MS is often diagnosed in young adults, typically between their late teens and early thirties. The onset of the disease during this period can significantly impact life choices, requiring long-term management and support due to the chronic nature of the condition.

The rationale behind this demographic focus includes the pathophysiology of MS, which is considered an autoimmune disease that often manifests earlier in life, contrasting with conditions that are more prevalent in older populations. While MS can occur in children and older adults, its incidence peaks in the 20-40 age range, making this group the most affected demographic.
