There's a lot of research about ADHD, more than many other mental diseases... There are a couple of things to remember: - ADHD is a deficit in executive function, and one of the main symptoms is impulsive behaviour (unable to control urges). This is what causes hyperactivity, but also causes things like angry outburts, and other improper social behaviour that follows into adulthood - The concensus among the research community is that ADHD is all negative. Measurably negative among all axes, especially when comparing people when on treatment and when not on it (drugs). I know some people like to do the whole "silver lining" thing (like with autism), but ADHD is a disease, an impairment. You should think of it like you would think of having the flu your entire life. Sure, you get good at vomiting your guts out cleanly, but not much great about it. - And a super important part is that this basically never goes away. There's this great analogy with a paraplegic. If you had a prosthetic leg, no matter how long you walked with it, you could never "train yourself" out of needing a prosthetic leg. Same thing with ADHD. The impulsive feelings don't leave, it's just that adults tend to be better at dealing with it than kids. But treatment is still very useful even later. (That last part is important: emotional outbursts at work can be a bit hard to manage...)
