Neuropsychological sequelae were pervasive in children and adolescents who sustained closed head injury when they were evaluated after cessation of posttraumatic amnesia. Impariment of long-term storage and retrieval processes in memory was found in about half of the total sample. Residual neuropsychological deficit was directly related to severity of acute injury as reflected by duration of coma and the Glasgow Coma Scale.
Levin et al. (Mon,) studied this question.
