Together, the studies conclude that the major changes to the definition of autism in the DSM-5 are well grounded in research and that the new criteria are more accurate than the current DSM-IV criteria.
But several studies recently published in child psychiatry journals suggest that it will be more difficult for new generations of high-functioning autistic people to receive a diagnosis because the DSM-5 criteria are too strict. When the APA publishes the DSM-5, people who have already met the criteria for autism in the current DSM-IV will not suddenly lose their current diagnosis as some parents have feared, nor will they lose state services. The devilish confusion is in the details. Psychiatrists and parents have voiced concerns that the new definition of autism in the DSM-5 will exclude many people from both a diagnosis and state services that depend on a diagnosis. The newest edition of the manual, the DSM-5, is slated for publication in May 2013. The controversy remains front and center because the American Psychiatric Association (APA) has almost finished redefining autism, along with all other mental disorders, in an overhaul of a hefty tome dubbed the Diagnostic and Statistical Manual of Mental Disorders ( DSM)-the essential reference guide that clinicians use when evaluating their patients. In many cases, the type and number of symptoms clinicians look for when diagnosing autism determines how easy or difficult it is for autistic people to access medical, social and educational services. Now, psychiatrists and members of the autistic community are embroiled in a more legitimate kerfuffle that centers on the definition of autism and how clinicians diagnose the disorder. The controversial idea that childhood vaccines trigger autism also persists, despite the fact that study after study has failed to find any evidence of such a link. People have been arguing about autism for a long time-about what causes it, how to treat it and whether it qualifies as a mental disorder.
