PDD-NOS Diagnosis

This is a snippet from the document "Clarification of the definition of Pervasive Developmental Disorder Not Otherwise Specified" by the American Psychiatric Association which can be found in their website.

"...change in the wording of PDDNOS to revert to the original construct. The new wording in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) is as follows:

“This category should be used when there is a severe and pervasive impairment in the development of reciprocal social interaction associated with impairment in either verbal and nonverbal communication skills, or with the presence of stereotyped behavior, interests, and activities, but the criteria are not met for a specific Pervasive Developmental Disorder, Schizophrenia, Schizotypal Personality Disorder, or Avoidant Personality Disorder.”
