CNN has a fascinating and rather frightening story about the toll football (or the concussions acquired playing it) take on the brain:
But today, using tissue from retired NFL athletes culled posthumously, the Center for the Study of Traumatic Encephalopathy (CSTE) is shedding light on what concussions look like in the brain. The findings are stunning. Far from innocuous, invisible injuries, concussions confer tremendous brain damage. That damage has a name: chronic traumatic encephalopathy (CTE).
CTE has thus far been found in the brains of five out of five former NFL players. On Tuesday afternoon, researchers at the CSTE will release study results from the sixth NFL player exhibiting the same kind of damage.
“What’s been surprising is that it’s so extensive,” said Dr. Ann McKee, a neuropathologist at the Veterans Administration Hospital in Bedford, Massachusetts, and co-director of the CSTE. “It’s throughout the brain, not just on the superficial aspects of the brain, but it’s deep inside.”
CSTE studies reveal brown tangles flecked throughout the brain tissue of former NFL players who died young — some as early as their 30s or 40s.
McKee, who also studies Alzheimer’s disease, says the tangles closely resemble what might be found in the brain of an 80-year-old with dementia.
The study’s limitation to brains of athletes who died young probably creates a selection bias toward more heavily damaged brains. But still.
There were some alarming photos I couldn’t manage to swing over. Story’s definitely worth a look.
