Its been noted that a lot of these conditions are not on the rise per se, its just that doctors and parents are actively looking for the issues. There was a msn article, possibly newsweek just yesterday going over the rise of the aspergers and had a little chart showing levels of aspergers against the top metric of distinguished mentally-challenged, which is kinda silly. I mean kids ARE distinguished mentally-challenged, growing up is to deal with that lol.
Seriously tho, its not so much that people use it as a crutch as they are raised to treat this thing they are given as a crutch. A diagnosis of one of the various disorders that are en vogue these days should be presented as a challenge that should be handled with stoicism. I am not discounting severe cases, but EVERYONE has their quirks, kids are ALWAYS hyperactive and into trouble, I really dont know what has changed. I did so many stupid random things as a kid, I mean I lost count. Yet here I am, perfectly normal.
