I was surprised to hear about proposed changes in the upcoming DSM-V    around autism and aspergers. According to the ATV piece Saturday and the links. The criteria to diagnose autism is being sharply tightened. Aspergers is being eliminated as a diagnosable disease.
Let's discuss them separately. From the ATV report there was a study back in 1994 and even then half of the children diagnosed with autism were misdiagnosed and didn't even have it. The DSM is recognizing that diagnosis is too loose, too subjective, too prone to pressure from self interested psychologists who know how lucrative a diagnosis is, especially when it is obvious what the parent wants to hear, especially when there's a benefits plan to stick with the bill.
As for aspergers. This is a "disease" whose symptoms include holding down high paying jobs and being in stable long term relationships. How many websites are out there about "husband has aspergers"? honey if there was a problem why did you get married? why did you stay married? why did you have children and then more children? You didn't seem to mind living off his paycheque all those years or stuffing your face with prescription drugs off his benefits plan.
It took the APA a lot of courage to make this move. There is an enormous entrenched industry in big pharma and psychologists around the status quo. They won't give up the gravy train without a fight. We already see the media starting to mobilize with the ATV piece. I expect a lot more resistance.
