Verbal learning and memory following pediatric closed-head injury.

In this study, verbal learning and memory following pediatric closed-head injuries (CHI) using the children's version of the California Verbal Learning Test (CVLT). Participants included 47 children, ages 5-16 yr, with a history of CHI, and 47 matched, noninjured controls. Children with CHI performed more poorly than controls on the CVLT, although their deficits varied qualitatively as a function of injury severity. Those with mild/moderate injuries performed as well as controls on learning trials, but they recalled proportionally fewer words after a delay (although their recognition was intact). Severely injured children demonstrated deficits in learning, delayed recall, and recognition, compared to controls. The groups did not differ in learning characteristics, but children with severe CHI exhibited more intrusions than controls. Pediatric CHI are associated with specific disturbances in verbal learning and memory similar to those of adults with CHI but different from those of children with other developmental and neurological disorders.
