Selective Changes in Executive Functioning Ten Years After Severe Childhood Traumatic Brain Injury

Abstract

Pediatric traumatic brain injury (TBI) impacts on children's executive functions, but little is known of how such deficits evolve in the long term. Forty adolescents with TBI were assessed ten years post-injury and compared to 19 typically developing participants on a range of executive measures (attentional control, cognitive flexibility, goal setting, information processing). Children with mild or moderate TBI performed within age expectations on all tests; however, those with severe injuries had poorer performance on goal setting and processing speed tasks. Childhood TBI may result in subtle lasting changes in complex executive skills, which could require ongoing support into adulthood.
