A new version of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders has come out every decade or so (it varies widely) since 1952. 
It hasn’t substantially changed since 1994, but the next revision is slated to come out in 2013. It’s a pretty big event, as the book’s diagnostic criteria are used around the world to determine who is diagnosed with mental disorders.
With the release of the new version, lines may shift and folks who were diagnosed with mental disorders may find themselves “undiagnosed.” Others will have labels changed and gain labels they didn’t have before.
The latest draft proposal of the May 2013 revisions, upon which public comment will be accepted until April 20, 2010, was posted on Feb. 9. APA workgroups will review the comments and begin trials soon after. Benedict Carey rounded up and evaluated some of the biggest proposed changes for The New York Times. In addition to bipolar disorders in children and autism spectrum disorders, Carey discusses the sheer significance of the changes.
“Anything you put in that book, any little change you make, has huge implications not only for psychiatry but for pharmaceutical marketing, research, for the legal system, for who’s considered to be normal or not, for who’s considered disabled,” said Dr. Michael First, a professor of psychiatry at Columbia University who edited the fourth edition of the manual but is not involved in the fifth.
“And it has huge implications for stigma,” Dr. First continued, “because the more disorders you put in, the more people get labels, and the higher the risk that some get inappropriate treatment.”
