Parkinson's disease typically presents after which age?

• A. After age 20
• B. After age 40
• C. After age 50
• D. After age 65

Answer: (C)

Parkinson’s disease typically begins in late middle age to older adulthood. The underlying neurodegeneration affects dopaminergic neurons in the substantia nigra, and most people develop noticeable symptoms around age 60 or later. While earlier onset can occur, it’s less common and would be considered “early onset,” not the usual pattern. So the age range that best describes the common onset is late 50s to 60s, with many sources highlighting around 60 years as typical; among the choices, this makes onset after about 60–65 the most accurate portrayal, whereas onset after 50 would be earlier than the typical presentation.
