    Diagnostic Criteria for 299.80 Rhett's Disorder

        A.   All of the following:
                (1) apparently normal prenatal and perinatal development
                (2) apparently normal psychomotor development through the 
                  first  5 months after birth
                (3) normal head circumference at birth

 
      B.  Onset of all of the following after the period of normal development:
                (1)  deceleration of head growth between ages 5 and 48 months
                (2)  loss of previously acquired purposeful hand skills between ages 5 
                      and 30 months with the subsequent development of stereotyped hand
                      movements  (e.g., hand-wringing or hand washing)
                (3)  loss of social engagement early in the course
                       (although often social interaction development later)
                (4)  appearance of poorly coordinated gait or trunk movement
                (5)  severely impaired expressive and receptive language 
                       development  with  severe psychomotor retardation.




       299.80  Pervasive Developmental Disorder   (PDD-NOS)

                     Not Otherwise Specified (Including Atypical Autism)
                

               This category should be used when there is a severe and pervasive 
               impairment  in the  development of  reciprocal social interaction  or 
               verbal  and  nonverbal communication skills,  or when  stereotyped 
               behavior,  interests  and  activities  are present,  but the criteria are 
               not met for a specific  Pervasive Development Disorder, Schizophrenia, 
               Schizoptypal Personality  Disorder, or Avoidant  Personality Disorder.  
               For example this  category includes "atypical autism" -  presentations 
               that do not  meet the criteria for Autistic Disorder because of late
               age at onset, atypical symptomatology, or subthreshold symptomatology,
               or all of these.
