This article reviews the most significant demographic, neurological, and psychosocial factors affecting the occurrence of and recovery from traumatic head injury (THI) in children and adolescents. Review of the available literature suggests that, as with adults, there is no compelling evidence for persistent neurobehavioral deficits after mild THI in children. In contrast, neurobehavioral deficits are common in children who have sustained moderate to severe THI. This article emphasizes that a long-term developmental perspective that considers in concert injury, pre-injury, and post-injury variables is needed for a proper appreciation of possible sequelae of pediatric THI. Specific pitfalls in forensic assessments of these children are reviewed. Empirical findings are presented to support the position that neuropsychological evaluations of children with THI that do not consider pre-injury status are likely to lead to misattribution errors. Clinical implications are illustrated with a case example.
