What is the typical age range for onset of amyotrophic lateral sclerosis (ALS)?

Explanation:
ALS tends to begin in adulthood, with most cases starting in middle age. The majority of onset occurs between about 40 and 70 years, with many individuals first showing symptoms in their 50s. That makes the 40–70 years window the best reflection of when ALS commonly begins. While it can occur outside this range—sometimes in younger individuals or, less often, after age 70—the occurrences in those decades are less typical. Understanding this helps you recognize why this age span is the most representative for onset.
