Functional memory skills following traumatic brain injury in young children.
Traumatic brain injury (TBI) may have a profound impact on a child's ongoing development. Various risk factors have been found to predict outcome, but considerable variability remains unexplained. This study used a prospective, longitudinal design to examine recovery of memory function following TBI within the pre-school period. Forty-four children with TBI were divided according to injury severity (mild, moderate, severe), and compared to age and SES matched healthy controls (n = 26). Children were evaluated acutely and at 12 months post-injury using the Rivermead Behavioural Memory Test for Children. Results failed to show a clear dose-response relationship between injury severity and memory function during the acute phase of recovery. However, this relationship developed over time, with greater memory impairments evident for children with more severe TBI by 12 months post-injury. Children with mild TBI exhibited few memory problems.
