Brain injury"robs your life", claims former American football player Brent Boyd, who was diagnosed with brain damage in 1999.
The former National Football League (NFL) player also suffers with Alzheimer's disease, but scientists are concerned that both conditions may have been the result of multiple traumas sustained throughout his playing career.
Speaking to the Independent, Boyd estimated that his head would regularly sustain around 200 knocks every game.
He told the newspaper how his brain injury has affected his life after football. "Here I was, this guy, high-energy, self-starter, high-achiever, and all of a sudden I couldn't hold a menial job.
"When you damage your brain, you lose your character and I lost my personality, my drive."
Many medical professionals are calling for rule changes in contact sports such as American football, rugby and hockey amid concerns about the risk of spinal and brain injury.
Research published in the Canadian Medical Association Journal in April called for a bodychecking ban to be instituted across youth hockey, which is commonly associated with concussion.
