Which diagnosis best fits duration, episodicity, and exclusions?
A
Language disorder
Persistent difficulties in acquisition and use of language across modalities (spoken, written, sign, or other) due to deficits in comprehension or production, including reduced vocabulary, limited sentence structure, and impairments in discourse
AA. Persistent difficulties in acquisition and use of language across modalities (spoken, written, sign, or other) due to deficits in comprehension or production, including reduced vocabulary, limited sentence structure, and impairments in discourse B. Language abilities substantially and quantifiably below expected for age, resulting in functional limitations in effective communication, social participation, academic achievement, or occupational performance C. Onset in the early developmental period
BA. 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)
Common specifiers

BWith/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
BADHD (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)
