Is medial temporal injury responsible for pediatric postconcussion syndrome? A prospective controlled study with single-photon emission computerized tomography

Abstract

There exists significant MTH in pediatric patients with PPCS, which would imply that medial temporal lobe damage (involving the hippocampus and related structures) may occur after minor head injury and could be responsible for the symptoms of PPCS observed in this group of patients. Brain SPECT scans may thus help in the early identification of children prone to develop PPCS, and serial SPECT scanning may serve as a platform for testing the efficacy of various neurobehavioral and pharmacological interventions in these patients.
