"tough" even in dementia

In advance of a congressional hearing on the impact of football on the brain, the NFL has backed off of claims that the dementia findings in retired NFL players are unreliable.

In a new round of "he-said/she-said" the NFL is pointing at the Union, who is pointing at... well, it is not clear:
But the outside data on which he primarily based this conclusion was not only mishandled — the wrong numbers were taken from one published study, grossly overstating worldwide dementia rates — but the analysis also included several faulty assumptions, experts said in later interviews. Correcting for these errors indicated rates of dementia among N.F.L. retirees about four to five times the expected rate.

“This was a preliminary effort at the request of the union to understand the facts,” said Ell, adding that he was acting as a lawyer for the union. “I understand now that it was flawed. I believe the union wants the true facts to come out and welcomes inquiries into this area.”

Meanwhile, the now-demented ex-football players are sticking to the "tough guy" creed.
Rayfield Wright's caregiver, Jeannette DeVader, said that Wright had all the signs of early-onset dementia — including short-term memory loss and frequently getting lost — but that he would not see a neurologist, let alone apply to the 88 Plan. Wright confirmed that he did not want what he called the stigma: “Players don’t want to look at themselves that way. The truth is, you really don’t want to know.”

The wife of one player experiencing early-onset dementia, who asked not to be identified, said she would not apply for the 88 Plan while her husband was coherent enough to understand it.

“He would be devastated,” she said. “They were so proud as players. They’re not going to admit any weakness now, and I’m not going to break his heart by doing it for him.”

I didn't anticipate minimization of symptoms this late in the game...

the perils of youth...

A number of years ago, I became involved in an ongoing research project with a colleague (pardon the shameless plug) looking at the effects of concussion on youth athletes. We found evidence of long-term effects of concussion on cognitive functioning in small sample, and then validated and extended these effects in a much larger sample. Essentially, we concluded:
seem to be subtle yet significant prolonged neuropsychological effects in youth athletes with a history of two or more previous concussions.

Cut to 2009, and a recent case reported in today's NY Times reveals that the long-term effects of concussions on the brains of professional athletes extends to the brains of high school and college athletes who never played professionally.
“I’ve looked at more than 1,000 brains, and I’ve never seen this in any individual living a normal life — it’s only through head trauma,” said Dr. Ann McKee, an associate professor of neurology and pathology at the Boston University School of Medicine and co-director of its Center for the Study of Traumatic Encephalopathy. “The fact that we are seeing this disease, and it had a devastating effect on their lives, now in a 42-year-old who never played in the N.F.L. indicates that it’s a more pervasive problem than we recognize. What are we doing with our kids? Are we doing enough to protect against their developing this awful condition?”
