Do I have to tell the recruiter this info for the Marine Corps?

So in a few years (maybe a year if I get my parents to sign up my enlistment) I am going to enlist in the Marine Corps. Back in like 3rd grade I was like diagnosed with ADHD and was put on medicine, had these group sessions, and had my school pressuring my parents to do all this. Eventually, my parents just stopped giving me the crap. Im hyper at times still, but I dont think this will really effect anything.Then in 6th grade the nurse and mom thought I had sports asthma or asthma in general and even had me breathe into something after running to see if I was normal or not. It was NOT an inhaler, merely this test thing that had like a bunch of different colors and numbers and it just tested if I was at normal breathing or not. We stopped that, since the doctor really didnt diagnose me, and never really finished the testing. Bottom line, never diagnosed or had an inhaler. One last thing, I have no full brothers and sisters, I have one half brother and half two half sisters from my dad. I am my moms only kid. I just think I was a bad runner before (still not great) and also I saw a big improvement in 8th grade when I was in wrestling and freshman year I wasnt too bad, but not that great. Now that im not in wrestling, Im to a good runner. But I will work on that. So do I have to tell the recruiter this info. I wanted to really know about the ADHD, can you be a Marine Scout sniper? I dont know if I will ever go for that, but maybe I will. Thanks.
