I worked at an after school program for youth and there were children fewer than ten years old being diagnosed with ADHD which I believe has "adult" in the name. I don't think age 10 or any age before then is a meaningful time to diagnose, but mom did not complain because he was more calm and less of a frantic chaotic child (one of three) while she worked full time. Quite sad, yet I see the temptation for parents as well.
