These new positron emission tomography studies using unique injectable contrast agents can now detect depositions of tau proteins in the brain. Compared with healthy controls who had not sustained head injuries, the NFL players with cognitive and neuropsychiatric symptoms had significantly higher deposits of tau protein on imaging.  The more years of tackle football a player had under his belt, the greater the accumulation of tau protein in the brain. This study marks the beginni
