Tackling Athletes' Brain Trauma Before It Killscarmendrahl (2593679) writes "In 2007, pro wrestler Chris (The Canadian Crippler) Benoit killed his son, his wife, and himself. Benoit's autopsy showed he had chronic traumatic encephalopathy (CTE), a progressive, brain-damaging disorder. He's far from the only athlete to be affected. The signatures of the disease have shown up in autopsies of ice hockey players, boxers, and NFL retirees. Researchers want to detect brain trauma while athletes are still alive. They're zeroing in on features like aggregates of the protein tau. Among the diagnostic hopefuls are positron emission tomography (PET) imaging; diffusion tensor imaging, which is a type of MRI; and cerebrospinal fluid sampling."
