Mild traumatic brain injury (TBI) is defined as a head trauma resulting in a brief loss of consciousness and/or alteration of mental state. Diagnostic methods to determine the extent of injury to the brain and potential long-term damage in patients are lacking. In this Review, the authors discuss the need for fluid biomarkers of mild TBI, and the potential validation of biomarkers before clinical implementation.
