Striking Evidence Linking Football to Brain Disease Sparks Calls for More ResearchThe biggest study of its kind offers the best evidence to date linking the sport to mood and cognitive impairmentsBy Mo Costandi on August 3, 2017
The controversy began about 10 years ago, when it emerged that the National Football League had first tried to cover up evidence linking repetitive head injuries in players to chronic traumatic encephalopathy (CTE), a progressive neurodegenerative disorder, and then to discredit the scientists doing the work. Since then evidence supporting this link has grown as an increasing number of players have come forward to report that they are suffering from depression, and some have committed suicide. And yet, exactly how repetitive head injuries are linked to CTE development and the psychiatric symptoms associated with it is still a matter of debate.
