Purpose: Co-occurring attention-deficit/hyperactivity disorder (ADHD) and communication disorders represent a frequently encountered challenge for school-based practitioners. The purpose of the present study was to examine in more detail the clinical phenomenology of co-occurring ADHD and language impairments (LIs). Method: Measures of nonword repetition, sentence recall, and tense marking were collected from 57 seven-to nine-year-old children. The performances of children with ADHD+LI status were compared with those of children with specific language impairment (SLI) and children with typical development (TD). Results: ADHD status had no independent detrimental impact on the affected children's LIs (SLI = ADHD+LI < TD). A modest positive correlation was found between the severity of children's ADHD symptoms and their sentence recall performance, suggesting a tendency for affected children who had higher levels of ADHD symptoms to perform better than those children with lower levels. Conclusion: These outcomes are difficult to reconcile with attention-deficit/information-processing accounts of the core deficits associated with SLI. Potential protective mechanisms associated with ADHD status are discussed.
