Abstract
Traumatic brain injury (TBI) is a multistep interaction of brain antigens, cytokine-mediated
humeral, and cellular immune reactions. Because of the limitations of clinical and
radiological evaluation in TBI, there has been a considerable advancement toward the
need for developing biomarkers that can predict the severity of TBI. Blood-based brain
biomarkers hold the potential to predict the absence of intracranial injury and thus
decrease unnecessary brain computed tomographic scanning. Various biomarkers have
been studied that detects neuronal, axonal, and blood–brain barrier integrity. Biomarkers
are still under investigation and hold promise in the future evaluation of TBI patients.
They can be used for grading as well as a prognostication of head injury.
