At what life stage do Huntington's disease symptoms typically first appear?

• A. Adolescence
• B. Late infancy
• C. Childhood
• D. Adulthood

Answer: (D)

Huntington's disease is a genetic disorder where brain degeneration progresses over many years, so symptoms typically appear after reaching adulthood. Most people first notice movement, cognitive, or psychiatric changes in their 30s to 50s. There are rare juvenile cases, but those occur with unusually large genetic repeats and are not the common pattern. Therefore adulthood best fits how this disease usually presents. Adolescence, late infancy, or childhood onset would be atypical for the standard course.
