Diagnostic Milestones
One tremendous accomplishment for the field of sensory processing! Sensory features will be recognized in the 2013 revision of the Diagnostic and Statistical Manual (DSM-5) as part of autism spectrum disorders. The labels hyper-sensitivity (Sensory Over-responsivity) and hypo-sensitivity (Sensory Under-responsivity) will be used. We remain optimistic and encouraged by this development and plan to continue our efforts to research SPD as a stand-alone diagnosis. See Dr. Miller's response to this news on our DSM Central page.

Even as the Sensory Processing Disorder Foundation was assembling its first-stage application for the DSM-5, we were taking an active role in advocating for recognition of Sensory Processing Disorder as a separate diagnostic category in other standard diagnostic manuals. As a result of these efforts, SPD is now included in two important diagnostic manuals for health care providers and others.

The inclusion of SPD in these two manuals already is making it easier for children with SPD to be properly diagnosed and treated.

Zero to Three

In 2006, Diagnostic Classification: Zero to Three: Diagnostic Classification of Mental Health in Developmental Disorders in Infancy and Early Childhood recognized SPD as Sensory Processing Disorders of Regulation, a diagnostic category for infants and toddlers. Zero to Three was the first developmentally based system for diagnosing mental health and developmental disorders when it was first published in 1994. The inclusion of SPD in the 2nd edition was based upon expert consultation solicited by Zero to Three's editors and provided by Dr. Lucy Jane Miller and a committee constituted by the Sensory Processing Disorder Foundation.


The Diagnostic Manual for Infancy and Early Childhood is published by the esteemed Interdisciplinary Council on Developmental and Learning Disabilities. Founded by the late Stanley Greenspan and Serena Wieder, the ICDL is a pioneer in its work to advance the identification, prevention, and treatment of developmental and learning disorders. SPD was included in the Diagnostic Manual for the first time in 2007 as Regulatory Sensory Processing Disorder.
