Great article in the New Yorker by Ben McGrath. The link, I hope, is posted below. I have also posted a few clips.
“What we now know, from reading Schwarz, is that retired N.F.L. players are five to nineteen times as likely as the general population to have received a dementia-related diagnosis; that the helmet-manufacturing industry is overseen by a volunteer consortium funded largely by helmet manufacturers; and that Lou Gehrig may not actually have had the disease that bears his name but suffered from concussion-related trauma instead. (Since 1960, fourteen N.F.L. players have had a diagnosis of amyotrophic lateral sclerosis, which is about twelve more than you would expect from a random population sample.) In the manner of Elisabeth Kübler-Ross, Dr. Maroon has delineated four stages in the N.F.L.’s reaction to the reality of brain damage: active resistance and passive resistance, shifting to passive acceptance and, finally, in the past few months, active acceptance. “What we’re seeing now is that major cultural shift, and I think Alan took a lot of barbs, and a lot of hits, initially, for his observations,” Maroon said.”
“Chronic traumatic encephalopathy, or C.T.E., is the name for a condition that is believed to result from major collisions—or from the accumulation of subconcussions that are nowhere near as noticeable, including those incurred in practice. It was first diagnosed, in 2002, in the brain of the Pittsburgh Steelers Hall of Fame center Mike Webster, who died of a heart attack after living out of his truck for a time. It was next diagnosed in one of Webster’s old teammates on the Steelers’ offensive line, Terry Long, who killed himself by drinking antifreeze. Long overlapped, at the end of his career, with Justin Strzelczyk, who was also found to have C.T.E. after he crashed, fatally, into a tanker truck, while driving the wrong way down the New York Thruway.”
