Study of Neurobehavioral Outcome in Children or Adolescents With Closed Head Injuries

OBJECTIVES: I. Determine the relationship of closed head injury (CHI) severity, focal brain lesions, and the age at injury to the development of working memory, inhibition, and metacognitive skills in children or adolescents with CHI of varying severity. II. Assess the development of working memory, inhibition, and metacognitive skills in relation to discourse functions, scholastic achievement, and adaptive behavior in these patients. III. Determine the relationship between impaired inhibition, metacognitive skills, and the emergence of psychiatric disorder in these patients.
