His apparent suicide was the third by a former NFL player since February 2011. First, former Chicago Bears safety Dave Duerson shot himself in the chest — after writing a note asking that his brain be studied for chronic traumatic encephalopathy — a disease linked to depression. Then last month, former Atlanta Falcon Ray Easterling shot himself in the head. He was part of a lawsuit against the NFL over head injuries and was suffering from dementia.
Researchers at Boston University confirmed last May that Duerson did indeed have chronic traumatic encephalopathy. Now, they're asking to be able to study Seau's brain. And, according to the Los Angeles Times, Seau's family has agreed to allow his brain to be studied. That word comes from San Diego Chargers chaplain Shawn Mitchell. Seau, a linebacker, spent most of his NFL career with that team.
