The Diagnostic and Statistical Manual of Mental Disorders, known as the DSM, is the publication that mental health professionals use to diagnose patients. The DSM was revised last year after a great deal of discussion, and the current version, the 5th edition, is known as the DSM-5. One of the most controversial changes made in the DSM-5 was the elimination of diagnoses of Asperger’s Syndrome and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). Many people formerly diagnosed with Asperger’s or PDD-NOS will now fit under the new definition of Autism Spectrum Disorder (ASD). Those that don’t may fall under a new diagnosis called Social Communication Disorder. The DSM-5 also combined learning disorders of reading, writing, and math into one general category, and changed the way that ADD is diagnosed and classified. If your student has a diagnosis under the DSM-IV, the best practice would be to ask your clinician to revise the diagnosis so that it is consistent with the DSM-5.
