When he ended his life last year by shooting himself in the chest, Junior Seau had a degenerative brain disease often linked with repeated blows to the head.
National Institutes of Health researchers said Thursday the former NFL linebacker's abnormalities are consistent with chronic traumatic encephalopathy (CTE).
Seau played for 20 NFL seasons with San Diego, Miami and New England before retiring in 2009. He died at age 43 of a self-inflicted gunshot in May, and his family requested the analysis of his brain.
In the final years of his life, Seau had wild behavioral swings, according to his ex-wife Gina, along with signs of irrationality, forgetfulness, insomnia and depression.
Seau joins a list of several dozen football players who were found to have CTE. The NFL also faces lawsuits by thousands of ex-players who say the league withheld information on the harmful effects of concussions.
