Neurodevelopmental
Neurodevelopmental
Persistent difficulties in social use of verbal/nonverbal communication; ≥1 of: deficits in using communication for social purposes; inability to change communication to match context; difficulty following rules for conversations and storytelling; difficulty understanding what is not explicitly stated
Persistent deficits in social communication/interaction across multiple contexts (≥3 components: social-emotional reciprocity; nonverbal communicative behaviours; developing/maintaining relationships)
B. Deficits result in functional limitations in effective communication, social participation, social relationships, academic achievement, or occupational performance C. Onset in the early developmental period D. Symptoms not attributable to another medical/neurological condition or low abilities in word structure/grammar; not better explained by ASD, intellectual disability, global developmental delay, or another mental disorder
B. Restricted, repetitive patterns of behaviour/interests/activities (≥2 of: stereotyped/repetitive motor movements; insistence on sameness/inflexible routines; highly restricted interests; hyper/hyporeactivity to sensory input) C. Symptoms present in early developmental period (may not fully manifest until social demands exceed capacity) D. Cause clinically significant impairment in social, occupational, or other important areas of functioning

Severity: Mild; Severity: Moderate; Severity: Severe
With/without accompanying intellectual impairment; With/without accompanying language impairment; Associated with a known medical or genetic condition; Associated with another neurodevelopmental, mental, or behavioural disorder
ASD (social communication deficits + RRBs - mutually exclusive; if RRBs present, diagnose ASD); Language disorder (structure and vocabulary impaired, not just pragmatic use); Intellectual disability (social communication deficits proportional to global impairment)
ADHD (comorbid in ~50%; social deficits not as pervasive; no RRBs - code both when criteria independently met); Social anxiety disorder (fear of negative evaluation; social motivation and desire intact); Social (pragmatic) communication disorder (social deficits without RRBs - mutually exclusive with ASD)
