UCLA Study: Mild Traumatic Brain Injury Revealed by Biomarkers
Concussions, which are actually mild traumatic brain injuries (TBI’s), often go undiagnosed and can lead to lasting neurological impairment, especially if the injuries recur. Researchers at UCLA have identified biomarkers that could aid doctors in the diagnosis of traumatic brain injuries with only a simple blood test. Brain cells called astrocytes, release proteins as biomarkers into the bloodstream when the astrocytes outer membranes rupture from impact or shaking. Doctors currently rely on CT scans or a scoring system to describe the level of a patient’s consciousness after suffering a blow to the head. However, neither method has shown to accurately predict recovery or disability while milder [...]
