The American Psychiatric Association (APA) posted a video of Susan E. Swedo, M.D. and Chair of the APA’s work group that developed the revised definition of “learning disorder” for APA’s Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5), explaining that the new definition will allow psychiatrists to use a broad classification and then focus on specific characteristics of individual cases. You can watch this 50-sec video of Dr. Swedo explaining not very much about what’s been a pretty controversial decision.
I would encourage folks not to work themselves into too much of a lather about the APA’s decision to alter its definition of “learning disorders.” The psychiatrists’ definition of these problems doesn’t have much effect in the USA on the legal definition of LD that influences decisions about services in schools. The APA (not, by the way, to be confused with the American Psychological Association, aka “APA”) uses its definition for the purposes of classification and (importantly) billing insurance companies. The diagnostic and statistical manuals are designed to be used by “a wide range of health and mental health professionals, including psychiatrists and other physicians, psychologists, social workers, nurses, occupational and rehabilitation therapists, and counselors” (see the DSM site), not by educators.
For folks wanting to learn more on this topic, the Learning Disabilities Association of America posted a brief document in the summer of 2012 in which Larry Silver summarized background and updated information about DSM and learning disorders in DSM-5.
