Impact of pediatric traumatic brain injury on components of verbal memory.

This 3-month longitudinal study examined spared and impaired components of verbal learning and memory after pediatric traumatic brain injury (TBI), using the California Verbal Learning Test for Children. School-aged participants with severe or mild-to-moderate TBI were compared to traumatically injured control subjects without head trauma. Participants were initially evaluated approximately 1 month post injury, and again 3 months later. At Times 1 and 2, participants with severe TBI displayed deficits in immediate recall, delayed recall, and recognition accuracy, consistent with a mild encoding deficit. In both evaluations, participants with mild-to-moderate TBI performed similarly to controls. On average, mild verbal encoding deficits appear to be associated with severe, but not mild-to-moderate, pediatric TBI in the first several months post injury.
