299.80 Asperger’s Disorder
Qualitative impairment in social interaction, as manifested by at least two of the following:
marked impairment in the use of multiple nonverbal behaviors, such as eye-to-eye gaze, facial expression, body postures, and gestures to regulate social interaction
failure to develop peer relationships appropriate to developmental level
a lack of spontaneous seeking to share enjoyment, interests, or achievements with other people (e.g., by a lack of showing, bringing, or pointing out objects of interest to other people)
lack of social or emotional reciprocity
Restricted, repetitive, and stereotyped patterns of behavior, interests, and activities, as manifested by at least one of the following:
encompassing preoccupation with one or more stereotyped and restricted patterns of interest that is abnormal either in intensity or focus
apparently inflexible adherence to specific, nonfunctional routines or rituals
stereotyped and repetitive motor mannerisms (e.g., hand or finger flapping or twisting, or complex whole-body movements)
persistent preoccupation with parts of objects
The disturbance causes clinically significant impairment in social, occupational, or other important areas of functioning.
There is no clinically significant general delay in language (e.g., single words used by age 2 years, communicative phrases used by age 3 years).
There is no clinically significant delay in cognitive development or in the development of age-appropriate self-help skills, adaptive behavior (other than in social interaction), and curiosity about the environment in childhood.
Criteria are not met for another specific pervasive developmental disorder or schizophrenia.
299.80 Rett’s Disorder
All of the following:
apparently normal prenatal and perinatal development
apparently normal psychomotor development through the first 5 months after birth
normal head circumference at birth
Onset of all of the following after the period of normal development:
deceleration of head growth between ages 5 and 48 months
loss of previously acquired purposeful hand skills between ages 5 and 30 months with the subsequent development of stereotyped hand movements (i.e., hand-wringing or hand washing)
loss of social engagement early in the course (although often social interaction develops later)
appearance of poorly coordinated gait or trunk movements
severely impaired expressive and receptive language development with severe psychomotor retardation
299.10 Childhood Disintegrative Disorder
Apparently normal development for at least the first 2 years after birth as manifested by the presence of age-appropriate verbal and nonverbal communication, social relationships, play, and adaptive behavior.
Clinically significant loss of previously acquired skills (before age 10 years) in at least two of the following areas:
expressive or receptive language
social skills or adaptive behavior
bowel or bladder control
play
motor skills
Abnormalities of functioning in at least two of the following areas:
qualitative impairement in social interaction (e.g., impairment in nonverbal behaviors, failure to develop peer relationships, lack of social or emotional reciprocity)
qualitative impairments in communication (e.g., delay or lack of spoken language, inability to initiate or sustain a conversation, stereotyped and repetitive use of language, lack of varied make-believe play)
restricted, repetitive, and stereotyped patterns of behavior, interests, and activities, including motor stereotypies and mannerisms
The disturbance is not better accounted for by another specific pervasive developmental disorder or by schizophrenia.
