Plasma brain-derived neurotrophic factor levels after severe traumatic brain injury

摘要

Objective: Severe traumatic brain injury (TBI) is associated with a 30-70% mortality rate. Nevertheless, in clinical practice there are no effective biomarkers for the prediction of fatal outcome following severe TBI. Therefore, the aim was to determine whether brain-derived neurotrophic factor (BDNF) plasma levels are associated with intensive care unit (ICU) mortality in patients with severe TBI.
