I think it more comes from how a lot of supposed mental disorders, are more of a conflict of that individual and the society they live in. If society was structured in a way for ADHD people to be able to contribute that is structured around how their brain works, there wouldn't be a disability in the first place. Not all, of course, but many. How we shouldn't be positing these people as 'broken' because their brains work slightly different, but because our society isn't structured in a way to allow them to contribute in a way that works best for them.
