Long-term Intellectual Outcome of Traumatic Brain Injury in Children: Limits to Neuroplasticity of the Young Brain?

Trauma is the most frequent cause of acquired brain injury in young children, but few studies of long-term intellectual outcome have been published. With a high incidence of inflicted injury in young children, long-term outcome data on accidental traumatic brain injury (TBI) in young children is especially sparse. In these 2 reports from the same children's hospital, there are noteworthy differences in the intellectual outcomes. Crowe et al1 followed up 53 children who had sustained TBI (20 mild, 33 moderate to severe) before age 3 years and tested 27 healthy children with similar demographic features for comparison. Two-thirds of the children who had sustained moderate to severe TBI were injured in falls. Socioeconomic level of the family at the time of injury was the strongest predictor of intellectual level at follow-up when the children were 4 to 6 years old. The nonsignificant effect of acute TBI severity and the generally average range of intellectual function are unexpected findings. However, the classification … Address correspondence to Harvey S.
