Approximately 20% of mild traumatic brain injury (mTBI) are sports related concussive injuries, of which nearly half receive no medical attention. During this acute post traumatic period, the brain appears to be more susceptible to injury and return to play (RTP) guidelines are made further more difficult by studies showing metabolic changes up to 30 days after a concussive event. We image 26 athletes, 7 acutely post concussion and show an acute reduction in NAA/Cho ratio that appears to normalize on RTP.
