I don't think it will adversly affect training. If anything, as others have mentioned, it might improve things.
I don't know if I"d like to have ADD while fighting, while being hyperactive while striking sounds like a good idea, I would be afraid of the attention deficit part. The last thing I need during a fight is to think about my training and then how that one day my girlfriend came to visit me. Later we went to dinner and then she came over. For dinner I had some steak, and I like steak and have been eating it since I was young. When I was younger I always got in trouble in school for acting up. This one kid, haha, this is so funny, his name was Timmy and he..... Then all of a sudden get KTFO by your opponent.
