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
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
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 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 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
Common specifiers

BSeverity: Mild; Severity: Moderate; Severity: Severe
