The point I was trying to make was that I don't think
Aspergers is trying to replace ADD, as you mentioned earlier. If they are false positives, they happen for different reasons. ADD or ADHD can get diagnosed by MDs, Aspergers I don't believe is being diagnosed by MDs. If an overly stimulated kid is given a stimulant and becomes a more focused child it is easy to diagnose that as ADD. There may be no way to tell whether the child just wasn't able to learn to focus or there really is a biological problem with the kids activators and inhibitors. With enough motivation, kids learn to focus if they are able. Learning language pragmatics is not as easy to pick up once you have failed to learn them at the usual developmental stage.
