A-20 Do Children With LD and/or ADHD Differ at Baseline on a Pediatric Measure Used to Assess Concussion?

Abstract

Abstract Objective To examine differences at baseline between children with ADHD and/or LD vs. children with neither ADHD/LD on 1) neurocognitive scores and 2) child- and parent-reported concussion symptoms. Method Retrospective data was obtained for 1856 children ages 5–11 who were assessed at baseline using ImPACT Pediatric. Groups were determined based on parent-reported diagnosis of their child at baseline (ADHD and/or LD vs. neither ADHD/LD), and groups were compared on the four factor scores: Sequential Memory, Word Memory, Visual Memory, and Rapid Processing and on child- and parent-reported concussion symptoms using a series of ANOVAs. Results ANOVAs revealed that children with ADHD and/or LD performed significantly worse than children without ADHD/LD on Sequential Memory (F(1,1845) = 69.86, p < .001)) and Word Memory (F(1,1853) = 10.36, p = .001)). In contrast, children with ADHD and/or LD performed significantly better on the neurocognitive measures of Visual Memory [(F(1,1845) = 4.94, p = .026)] and Rapid Processing [(F(1,1853) = 20.35, p < .001). Symptom reporting was significantly greater in the ADHD and/or LD group for both child (F(1,1853) = 30.21, p < .001) and parent (F(1,1853) = 34.64, p < .001) reported symptoms. Conclusions The current study demonstrated differences at baseline in children on neurocognitive performance and concussion symptom reporting based on diagnostic group. Analysis of symptom reporting suggested that children with pre-existing diagnoses of ADHD and/or LD and their parents may report concussion-like symptoms at baseline, prior to ever experiencing a concussion. This finding has clinical implications for interpretation of post-concussion symptoms without a baseline comparison in children with pre-existing diagnoses such as ADHD and/or LD.
