(A) Persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following, currently or by history(examples are illustrative not exhaustive):
1) Deficits in social-emotional reciprocity, ranging, for example ,from abnormal social approach and failure of normal back and forth conversation; to reduced sharing of interest, emotions, or affect; to failure to initiate or respond to social interactions.
2) Deficits in nonverbal communicative behaviors used for social interaction, ranging for example, from poorly integrated verbal and nonverbal communication; to abnormalities in contact and body language or deficits in understandings and use of gesture; to a total lack of facial expressions and nonverbal communication.
3) Deficits in developing, maintaining and understanding relationship, ranging, for example, from difficulties adjusting behavior to suit various social contexts; to difficulties in sharing imaginative play or in making friends; to absence of interest in peers.
Specify current severity based on social Communication impairments and, restricted, repetitive patterns of behavior.
(B) Restricted respective patterns of behavior, interest ,or activities, as manifested by at least two the following, currently or by history (examples are illustrative, not exhaustive):
1) Stereotyped or respective motor movements, use of objects, or speech (e.g., simple motor stereotypies, lining up toys or flipping objects, echolalia, idiosyncratic phrases).
2) Insistence on sameness; inflexible adherence to routines, or ritualized patterns of verbal or nonverbal behaviors (e.g., extreme distress at small changes, difficulties with transactions, rigid thinking patterns, getting rituals, need to take same route or eat same food every day).
3) Highly restricted, fixated interest that abnormal in intensity or focus (e.g., strong attachment to or preoccupation with unusual objects, excessively circumscribed or perseverative interests).
4) Hyper or hyperactivity to sensory input or unusual interest in sensory aspects of environment (e.g., apparent indifference to pain/temperature, adverse response to specific sounds or textural, excessive smelling or touching of objects, visual f fascination with lights or movement).
Specify current severity based on social communication impairments and restricted, respective patterns of behavior.
(C) Symptoms must be present in early developmental period (but may not becomes fully manifest until social demands exceed limits capacities, or may be masked by learned strategies in later life).
(D) Symptoms cause clinically significant impairments in social, occupational, or other important areas of current functioning.
(E) These disturbances are not better explained by intellectual disability (intellectual developmental disorder) or global developmental delay. Intellectual disability and autism spectrum disorder frequency cooccur; to make comorbid diagnoses of autism spectrum disorder and intellectual disability, social communication should be bellow that expected for general developmental level.
