Chris Henry in 2007
BOB DOUGHTY: The death of Chris Henry is something of a mystery. He was arguing with his girlfriend before he died. It is unclear whether he fell from the vehicle or jumped on purpose. Tests show that more than fifty former athletes had C-T-E. However, doctors are unable to confirm its presence until after the person dies.
In the past, researchers believed that the only cause of C-T-E was a concussion. Chris Henry, for example, never missed a game with the Bengals or in college because of a concussion. This means one of two things. Either he hid the problem from his trainers and coaches. Or less severe hits can lead to C-T-E.
Researchers say his death should be a warning to other athletes. Concussions are not like most injuries. They can become life-threatening, but cannot be seen.
KATHERINE COLE: America's Centers for Disease Control and Prevention receives reports of about four million sports-related concussions every year. Concussions can result when an athlete is hit in the head. The brain will move around and sometimes strike the skull, or bony inside of the head. This can result in swelling. In extreme cases, it causes bleeding in the brain.
After suffering a concussion, a player might feel light-headed and pass out. He or she may also have problems with memory and feel sick to the stomach. Researchers are not saying that no one should play contact sports. They just want athletes to know that head injuries are serious. And, repeated head injuries are cause for concern.
