A study of American football players’ brains has found that will 99% of professional NFL athletes tested had a disease associated with head injuries.
The report published on Tuesday within the Journal of the American Medical Association studied 202 deceased players – 111 of them coming from the NFL.
All however one former National Football League player were found to have chronic traumatic encephalopathy (CTE).
The study will be the largest of its kind yet conducted, its authors say.
The invisible plague of concussion
Dr Ann McKee, director of Boston University’s CTE Center, which led the study, cautioned against drawing any immediate conclusions.
“There’s a tremendous selection bias,” she said, explaining how many of the brains were donated specifically by families who had suspected that will their loved ones were suffering coming from CTE, which researchers believe will be caused by repeated blows to the head.
“There’s no question that will there’s a problem in football. that will people who play football are at risk just for This kind of disease,” she told US media.
The neurodegenerative brain disease CTE will be typically found in people who have suffered repeated blows to the head, studies have found.
the idea causes a build-up of so-called tau proteins which can disable neuro-pathways along with cause memory loss, impaired judgment, confusion along using a variety of some other mental health issues.
All 202 players studied – ranging in age coming from 23 to 89 – were required to have football as their primary exposure to head trauma.
Of the 202 total players, 87% were found to have traces of CTE.
the idea was also found in 48 of 53 college players along with three of the 14 high school players.
Players featured within the study came coming from every position on the field, along with coming from high school, university, along with Canadian leagues, in addition to the NFL.
In a statement the NFL said the idea was grateful for the study along with the “value the idea adds within the ongoing quest for a better understanding of CTE”.
“There are still many unanswered questions relating to the cause, incidence along with prevalence of long-term effects of head trauma such as CTE,” the organisation continued.
“The NFL will be committed to supporting scientific research into CTE along with advancing progress within the prevention along with treatment of head injuries.”
The NFL in 2016 acknowledged for the 1st time that will there will be a connection between CTE along with football.
In 2015, a federal judge approved a class-action lawsuit brought against the NFL by thousands of players, who had alleged they had suffered brain damage as a result of concussions.
