Autism spectrum disorder with disorder of intellectual development and with impaired functional language

Transtorno do espectro autista com transtorno do desenvolvimento intelectual e deficiência da linguagem funcional

Definition

All definitional requirements for both autism spectrum disorder and disorder of intellectual development are met and there is marked impairment in or complete absence of ability relative to the individual’s age to use functional language for instrumental purposes (e.g., to express personal needs and desires). The co-occurring Disorder of intellectual development should be classified separately, using the appropriate category to designate severity (i.e., mild, moderate, severe, profound, provisional). Because autism spectrum disorder inherently involves social deficits, assessment of a co-occurring Disorder of intellectual development should place greater emphasis on intellectual, conceptual, and practical domains than on social adaptation
