Deficits in social communication and social interaction across multiple contexts, as manifested by:
- Deficits in social-emotional reciprocity
- Deficits in nonverbal communicative behaviors used for social interaction
- Deficits in developing, maintaining, and understanding relationships
Restricted, repetitive patterns of behavior, interests, or activities, as manifested by at least two of the following:
- Insistence on sameness, inflexible
- Highly restricted, fixated interests that are abnormal in intensity or focus
- Hyper- or hypoactive to sensory input or unusual interests in sensory aspects of the environment
Symptoms must be present in the early developmental period (but may not become fully manifest until social demands exceed limited capacities, or may be masked by learned strategies in later life).
Symptoms cause clinically significant impairment in social, occupational, or other important areas of current functioning.
These disturbances are not better explained by intellectual disability (intellectual developmental disorder) or global developmental delay. Intellectual disability and autism spectrum disorder frequently co-occur; to make comorbid diagnoses of autism spectrum disorder and intellectual disability, social communication should be below that expected for general developmental level.
