Brain Trauma Widespread Among High School Football Players

Football is a dangerous sport. Even with the best protective gear, sprained knees, pulled muscles and an occasional broken bone are part of the game. But seven years of research into the impact of head trauma in high school players points to new dangers that parents will find extremely alarming.

"We are seeing changes in brain activity even without a diagnosed concussion, even without any sign or symptoms showing up and that that occurs in a large population of our subjects," said Larry Leverenz, a clinical professor of health and kinesiology at Purdue University.

More than half of the players participating in the trials showed signs of altered neurological function and dramatic changes to the wiring and biochemistry of their brains, according to a series of studies published by the Purdue Neurotrauma Group.
