Brain Changes Found in High School Football Players Thought to Be Concussion-Free The findings represent a dilemma because they suggest athletes may suffer a form of injury that is difficult to diagnose. "The problem is that the usual clinical signs of a head injury are not present," said Larry Leverenz, an expert in athletic training and a clinical professor of health and kinesiology. "There is no sign or symptom that would indicate a need to pull these players out of a practice or game, so they just keep getting hit." Helmet sensor data indicate impact forces to the head range from 20 to more than 100 Gs. "To give you some perspective, a roller coaster subjects you to about 5 Gs and soccer players may experience up to 20 G accelerations from heading the ball," Nauman said. Head impacts cause the brain to bounce back and forth inside the skull, damaging neurons or surrounding tissue. The trauma can either break nerve fibers called axons or impair signaling junctions between neurons called synapses. The findings suggest the undiagnosed players suffer a different kind of brain injury than players who are diagnosed with a concussion.
Brain Docs Raise Concussion Alarm for Kids' Sports The risk of concussions from football and some other sports is so serious that a qualified athletic trainer should always be on the field -- at adult and children's games, and even at practice, a major doctors group said Monday. Following that advice from the American Academy of Neurology would be a dramatic change for youth sports programs, most of which don't have certified trainers. The doctors group recognizes it isn't necessarily feasible. One official called it a gold standard to strive for.

Junior Ice Hockey Study Uncovers Alarming Concussion Rates "The reluctance to report concussion symptoms may result from cultural factors, as expressed in several of the case studies -- athletes demonstrate perceived toughness to their parents, coaches, team mates and peers by playing through an injury; and the belief of the athlete that he or she is invincible, so winning overrides any consideration of the effect of the injury upon long-term health. It is imperative to bring about a cultural and philosophical change in this regard through stepped-up education efforts and enforcement of concussion protocols. At risk is something far more precious than winning a game, and that is the future health and well being of thousands of young athletes," concluded Dr. Echlin.

Position Statement On Sports Concussion 1. Any athlete who is suspected to have suffered a concussion should be removed from participation until he or she is evaluated by a physician with training in the evaluation and management of sports concussions 2. No athlete should be allowed to participate in sports if he or she is still experiencing symptoms from a concussion. 3. Following a concussion, a neurologist or physician with proper training should be consulted prior to clearing the athlete for return to participation. 4. A certified athletic trainer should be present at all sporting events, including practices, where athletes are at risk for concussion. 5. Education efforts should be maximized to improve the understanding of concussion by all athletes, parents, and coaches.

(J Clin Exp Neuropsychol. 2010) The latter finding adds to previous evidence of disproportionately worse outcome in athletes presenting with a history of three or more concussions relative to those with fewer concussions.

Postconcussion syndrome after mild traumatic brain injury in Western Greece. (J Trauma. 2010)"BACKGROUND: The prevalence of postconcussion syndrome (PCS) in the first weeks after mild traumatic brain injury varies from 40% to 80%. However, as many as 50% of patients report symptoms for up to 3 months and 10% to 15% for more than a year."
