I'm not sure what you mean by "real disorder" here. If you read the literature on "medicalization of deviance" it's pretty clear that "real disorder" is a very fuzzy and socially determined bucket.

If you personally need medication, great, you should use it. But I don't think that justifies dumping on the people who don't. Or the people who do, but also see benefits in their different cognitive style. My ADHD has been a pain in the ass for me, but I'd never trade it away, as I like the benefits.
