My daughter has ADHD. We did not medicate her until she was 7.5. She is 10 years old now. She is very physically talented, but the gym actually waited a year before putting her on team due to focus difficulties. She is also very smart, but she has been slow to mature and seems a year below her actual age. The medication helped her tremendously. She takes long-acting in the morning and a short acting to cover homework and late afternoon/evening practices. Body awareness has always been a bit harder for her than the other kids. I think it takes a little bit longer for the signal to reach her brain to get tight. But, she has terrific speed and progressed pretty quickly up the levels. She got better and better each year. She does not have issues falling asleep due to the medication. It seems to have the opposite effect of calming her very active brain. She is very tiny and thin though. Some of that is genetics, but I'm sure the medication plays a role. Gymnastics has actually been a great sport for her!
