Concussions seem to be the “hot” injury right now. Kids are missing more school because of concussions than any other injury and the diagnosis and treatment continues to be controversial. The scale of these are very broad as well. Sometimes there is minimal trauma and the athlete has symptoms for weeks, but other times the injury appears more severe and the symptoms resolve quickly.
This new study reported in JAMA found that microRNA levels in saliva were able to predict the recovery period for individuals who suffered a concussion. An objective test that could predict when patients could go back to school, work and sports. I think this would be very helpful.
