Which disease has the youngest typical onset age among the listed conditions?

• A. Multiple sclerosis
• B. Rheumatoid arthritis
• C. Spinal stenosis
• D. Paget's disease

Answer: (B)

Onset age patterns help separate these conditions in a physical therapy screen. Conditions driven by inflammatory or autoimmune processes often appear earlier in adulthood, while degenerative bone conditions show up later. Rheumatoid arthritis is classically first noticed in early to middle adulthood, commonly in the 30s to 40s. In contrast, spinal stenosis and Paget’s disease tend to present much later in life—spinal stenosis usually after age 50 and Paget’s disease after age 60. Multiple sclerosis commonly begins in young adulthood as well, but when considering the typical population pattern used in exams, rheumatoid arthritis is the condition most consistently characterized by the youngest onset among these options. So, rheumatoid arthritis is the best choice for having the youngest typical onset age.
