Differential consideration
ADHD
F90.xNeurodevelopmental
Why consider it
comorbid in ~50%; social deficits not as pervasive; no RRBs - code both when criteria independently met
Criteria and features to review
- A. ≥6 inattentive symptoms and/or ≥6 hyperactive-impulsive symptoms (≥5 for age ≥17) for ≥6 months, inconsistent with developmental level and negatively impacting activities
- B. Several symptoms present before age 12
- C. Symptoms present in ≥2 settings (e.g. home, school, work, with friends)
- D. Clear evidence of interference with or reduction in quality of social, academic, or occupational 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?
