A member asked:

What age do familial als start?

A doctor has provided 1 answer

Anytime, but: The scientific literature shows that it does not happen until about age 30, and is still rare until about age 45. It's reported that younger cases may be more likely familial than sporadic, but no specific details. An interesting article to look at: https://academic.oup.com/brain/article/135/9/2883/325075
