Remember the concern ('07) about concussions a while back? An update from the Sports Medicine blog: New Guidelines for Head Injury and Concussion in Youth Sports

An international panel of neurologists changed their recommendations regarding concussion care for young athletes. The new recommendations, published in The British Journal of Sports Medicine, say any athlete, 18 and under, who may have sustained a concussion during sports should not be allowed to return to activity the same day. The group's previous recommendation allowed the athlete to return to activity if cleared by a doctor or certified athletic trainer. The neurologists now believe it's too difficult to make an immediate determination of the seriousness of head injuries which makes it too dangerous for continued play to be considered safe.
