Brain trauma widespread among high school football players, researchers say

More than 50 percent of student athletes that play impact sports like football and soccer suffer from neural trauma and altered brain function, even when signs of concussion are not present, according to a series of research studies. Ben Gruber reports.

STORY: Everyone knows that 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. (SOUNDBITE) (English) LARRY LEVERENZ, CLINICAL PROFESSOR OF HEALTH AND KINESIOLOGY, PURDUE UNIVERSITY, SAYING: "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." 50 to 70 percent of the players participating in the trials showed signs of altered neurological function and dramatic changes to the wiring and biochemistry of their brains. (SOUNDBITE) (English) ERIC NAUMAN, PROFESSOR OF MECHANICAL AND BIOMEDICAL ENGINEERING, PURDUE UNIVERSITY, SAYING: "It's not just the neurons that get damaged, it's the glial cells, it's the vasculature.." (SOUNDBITE) (English) ERIC NAUMAN, PROFESSOR OF MECHANICAL AND BIOMEDICAL ENGINEERING, PURDUE UNIVERSITY, SAYING: "Basically in football and woman's soccer about half the team is experiencing these kinds of things, these kinds of changes. Some of them heal and some of them don't by the time they start playing their next season and that was the thing that really got us nervous." The researchers placed sensors on the athletes to record impact forces and coupled that data with brain scans and tests to gauge neurological function. They found that hits to the head that up until now were considered less dangerous may be the most dangerous of all…because they go unnoticed, occur more frequently and cause damage that could result in long lasting neurological problems. Based on their results, the researchers are developing equipment that better protects the head from high force impacts. (SOUNDBITE) (English) LARRY LEVERENZ, CLINICAL PROFESSOR OF HEALTH AND KINESIOLOGY, PURDUE UNIVERSITY, SAYING: "You're not going to change the game. You are not going to get rid of the game, at least. So how can you make changes that keep the spirit of the game there, keep players enjoying, keep fans enjoying the game but at the same time be safe." They say the technology to make these games safer exists. But to get them out of the lab and on to the field requires a general consensus that these sports are a lot more dangerous than previously thought.
