In Sweden at least it is classified as a disability, because whether or not it's a evolutionary adaptation, people that present typical ADHD traits are functionally disabled in modern society. Society should change to accommodate these traits, but we can't expect people with those traits to live in misery until then.

Yeah not to sound like a "deep" 15 year old but I think being able to function in our modern society is much more unnatural than the behaviors associated with ADHD. But since is the society we're in, having it really is a disability.

TL;DR: "we live in a society"
