Tragically, 95.6% of former National Football League (NFL) players who donated their brains to science tested positive for a brain disease. The disease is linked with repeated head trauma and concussions.
From 5 News Online:.
The former players were found to have had chronic traumatic encephalopathy, known as CTE, according to the U.S. Department of Veterans Affairs and Boston University.
However, the study results don’t necessarily mean that 96 percent of all NFL players are at risk for CTE. The brains came from players who, while they were alive, had concerns about CTE.
It’s not clear why some players develop the disease and others don’t.
The data was published on the website for the Concussion Legacy Foundation and first reported by the documentary TV program “Frontline.”
The NFL said it had taken several steps to make play safer. Among the changes in recent years has been conducting pregame medical assessments of players, along with on-field and postgame assessments of players involved in hard hits. Another has been moving the kickoff spot 5 yards forward, reducing the number of kick returns.
“We are dedicated to making football safer and continue to take steps to protect players, including rule changes, advanced sideline technology and expanded medical resources,” the league said. “We continue to make significant investments in independent research through our gifts to Boston University, the (National Institutes of Health) and other efforts to accelerate the science and understanding of these issues.”
In May, Dr. Russ Lonser, chairman of the NFL’s Head, Neck and Spine Subcommittee, said there has been a 25 percent reduction in concussions and 40 percent reduction in helmet-to-helmet hits in the past three seasons.
CTE is a progressive degenerative brain disease found in some athletes with a history of repetitive brain trauma.
The brain tissue of people found to have CTE displays an abnormal build-up of tau — a protein that, when it spills out of cells, can choke off, or disable, neural pathways controlling things like memory, judgment and fear.
CTE can be diagnosed only after death.
Earlier this year, the NFL and thousands of former players settled a lawsuit that provides up to $5 million per retired player for serious medical conditions associated with repeated head trauma.
While the lawsuit was a combination of hundreds of actions brought by more than 5,000 former players, it may apply to as many as 20,000 former ex-NFLers.
