Cognitive Development and the Immediate Postconcussion Assessment and Cognitive Testing: A Case for Separate Norms in Preadolescents.

With youth sports participation and concern about sports-related concussions both on the rise, it is important to properly measure cognitive function to ensure the clinical utility of baseline testing. Computerized testing batteries are often employed as baseline and postinjury measures of cognitive function, with the Immediate Postconcussion Assessment and Cognitive Testing (ImPACT) being the most used of all the current testing platforms. The current study compared 10- to 12-year-old children across the composite scores yielded by the ImPACT and provided normative data on each of the subtests used to calculate the composite scores. Normative data are separated by gender for athletes aged 10 to 12 years old, as this is the current age bracket used by the ImPACT. These norms may be helpful in the interpretation of the ImPACT clinical report and further delineation of areas of neurocognitive dysfunction.
