Concussions Detected by Checking for Dents in the Metabolome

A fall in the street, a tackle on the gridiron, a bomb blast on the battlefield—any of these events can result in a concussion, or mild traumatic brain injury (mTBI). We already know mTBIs are common, but, they may be even more common that we realize, given our lack of objective diagnostic measures. To find a way of detecting and confirming mTBIs more accurately, scientists are looking for mTBI biomarkers, chemical signs that linger, briefly, in our body fluids after concussive impacts.To
