What is the typical age range for multiple sclerosis onset?

• A. 21-40
• B. 40-70
• C. 60+
• D. 20-50

Answer: (A)

Multiple sclerosis most often begins in young adults. The typical onset is in the first three decades of life, with many people showing initial symptoms in their 20s and early 30s, and the majority presenting before age 40. That makes the range of 21-40 the best representation of the usual onset window. Onset after age 50 is uncommon for MS, and cases starting in the 60s or 70s are rare, which is why the other ranges are less representative. While there can be exceptions, the 21-40 window best reflects the common pattern clinicians expect in MS.
