DSM-V is Coming
The American Psychiatric Association will publish the fifth edition of Diagnostic and Statistical Manual of Mental Disorders (DSM-V) in May 2013.  Fox News reports:
“If we don’t loosen it a little bit, I suspect that some of these  high-functioning kids may actually either get shifted into a different  diagnosis,” said Dr. Thomas Frazier, who treats children with autism at the  Cleveland Clinic Children’s Hospital. “So, for example, they might move to a new  diagnosis called social communication disorder.”
Frazier said he is also  worried about children who are already classified, and how the reclassification  could affect the educational assistance they receive at school.
“Your  educational classification really indicates what kind of services and accommodations you're going to get at school,” he said. “And autism is one of the highest educational classifications; so many  people with autism get a significant amount of services through their school. I  think the worry by a lot of parents is that ‘if my child loses that  classification what happens?’ And we don’t know what’s going to happen yet.”
At Cato, Walter Olson worries that DSM-V will lead to an increase in claims under ADA and other laws.
