Cool chart on how the criteria has changed over the five editions.

Even those who do not live in the US are effected by this since other medical/scientific communities look to this to consider their criteria  

So many of us have been misdiagnosied 

quote: 

I recently asked a former president of the APA how he used the DSM in his daily work. He told me his secretary had just asked him for a diagnosis on a patient he’d been seeing for a couple of months so that she could bill the insurance company. “I hadn’t really formulated it,” he told me. He consulted theDSM-IV and concluded that the patient had obsessive-compulsive disorder.

“Did it change the way you treated her?” I asked, noting that he’d worked with her for quite a while without naming what she had.

“No.”

“So what would you say was the value of the diagnosis?”

“I got paid.”
