Language profiles in children with concussion.

Primary Objective: Inform the production of a screening tool for language in children with concussion. The authors predicted that children with a recent concussion would perform the cognitive-linguistic tasks more poorly, but some tasks may be more sensitive to concussion than others. Methods & Procedures: 22 elementary school aged children within 30 days of a concussion and age-matched peers with no history of concussion were assessed on a battery of novel language and cognitive-linguistic tasks. They also completed an auditory attention task and the Raven's Colored Progressive Matrices. Main Outcomes & Results: Children with a recent concussion scored significantly more poorly in novel tasks targeting category identification, grammaticality judgments, and recognizing target words presented in a short story than their age-matched peers with no such injury history. All observed effects had moderate sizes. Inclusion of these three tasks significantly improved prediction of concussion status over symptom score when controlling for the age of participants. Conclusions: The finding supports continued investigation of targeted linguistic tasks in children following concussion, particularly in the domains of semantic and syntactic access and verbal working memory. Future work developing brief language assessments specifically targeting children in this age range may provide a valuable addition to the existing tools for identifying the effects of concussion.
