IL6 and brain injury: Interestingly, the temporal profile of IL-6 points to a distinctly different inflammatory profile in sports-related concussion (SRC) and military concussion versus the general unselected population with mTBI; athletes show early acute elevation (<8 h) with a return to baseline within 48 h, highlighting an earlier resolution of the inflammatory response in comparison with the general unselected population showing alterations lasting up to six months after injury.
