I think it's great physicians are able to better diagnose disease and are able to see it when it manifests itself in populations where observation was missed or ignored for different reasons (bias, exposure, expectations, etc).

There needs to be better understanding so that boys don't get over diagnosed and women don't get underdiagnosed.

I find it unfortunate the author found it necessary to mention "white boys" throughout the article. What about ADHD in populations where there are few whites, say Asia, Africa, what has been observed there?

Do we need to inject everything with race and gender? I know it's important to lessen the effect of race and gender on things, but this over emphasis on race and gender on everything seems frivolous. Here I don't think it adds to the discussion.
