Timing of Traumatic Brain Injury in Childhood and Intellectual Outcome
Journal of Pediatric Psychology, 06/12/2012
Crowe LM et al. – Contrary to expectations, children injured in middle childhood demonstrated the poorest outcomes; this age potentially coincides with a critical period of brain and cognitive development.Methods
- Children with a TBI (n=181) were categorized into 4 age-at-injury groups-infant, preschool, middle childhood, and late childhood-and were evaluated at least 2-years post-TBI on IQ.
- Overall, the middle childhood group had lower IQ scores across all domains.
- Infant and preschool groups performed below the late childhood group on nonverbal and processing speed domains.
