Differential consideration
ASD
F84.0Neurodevelopmental
Why consider it
social communication deficits + RRBs - mutually exclusive; if RRBs present, diagnose ASD
Criteria and features to review
- A. Persistent deficits in social communication/interaction across multiple contexts (≥3 components: social-emotional reciprocity; nonverbal communicative behaviours; developing/maintaining relationships)
- 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
Questions to clarify
- Which documented criteria and exclusions are met for each possibility?
- What timeline, course, and functional change best distinguishes the alternatives?
- Are substance, medication, medical, developmental, and contextual explanations adequately assessed?
