AbstractExcitotoxicity and ischemia can result in oxidative stress after TBI. Female sex hormones are hypothesized to be neuroprotective after TBI by affecting multiple mechanisms of secondary injury, including oxidative damage, excitotoxicity and ischemia. Ca2+ mediated oxidative stress increases with age, and hypothermia is known to attenuate secondary injury. The purpose of this study was to determine if the relationship between cerebral spinal fluid (CSF) markers of excitotoxicity, ischemia, and oxidative damage are gender and age specific and the role of hypothermia in affecting these relationships. F2-isoprostane, glutamate, and lactate/pyruvate, were assessed in CSF from adults (n = 68) with severe TBI (Glasgow coma scale [GCS] score
