Chronic traumatic encephalopathy (CTE) is a neurodegenerative disorder most commonly associated with repetitive traumatic brain injury (TBI) and characterized by the presence of neurofibrillary tangles of tau protein, known as a tauopathy. Currently, the diagnosis of CTE can only be definitively established postmortem. However, a new positron emission tomography (PET) ligand, [(18)F]T807/AV1451, may provide the antemortem detection of tau aggregates, and thus various tauopathies, including CTE. Our goal was to examine [(18)F]T807/AV1451 retention in athletes with neuropsychiatric symptoms associated with a history of multiple concussions...

Head angular velocity, instead of acceleration, is more predictive of brain strains. Surprisingly, no study exists that investigates how shape variation in angular velocity profiles affects brain strains, beyond characteristics such as peak magnitude and impulse duration. In this study, we evaluated brain strain uncertainty due to variation in angular velocity profiles and further compared with that resulting from simplifying the profiles into idealized shapes. To do so, we used reconstructed head impacts from American National Football League for shape extraction and simulated head uniaxial coronal rotations from onset to full stop...

Professional American football players incur thousands of repetitive head impacts (RHIs) throughout their lifetime. The long-term consequences of RHI are not well characterized, but may include olfactory dysfunction. RHI has been associated with changes to brain regions involved in olfaction, and olfactory impairment is common after traumatic brain injury. Olfactory dysfunction is a frequent early sequelae of neurodegenerative diseases (e.g., Alzheimer's disease), and RHI is associated with the neurodegenerative disease, chronic traumatic encephalopathy (CTE)...

INTRODUCTION: Repetitive brain trauma (RBT) in American football has become a topic of recent interest. The objective of this study was to assess the interrelationships among neuroimaging findings with neurocognitive test performance and symptom endorsement in a cohort of retired professional (National Football League [NFL]) football players. METHODS: Magnetic resonance imaging (MRI) scans were performed in 45 retired NFL players. Three neuroimaging parameters were recorded by blinded, board-certified neuroradiologists: (1) the absence or presence of small or large cavum septum pellucidum; (2) a global mean score of fractional anisotropy (FA); and (3) the presence or absence of microhemorrhages (microbleeds)...

American football has become one of the most popular sports in the United States. Despite the millions of players at all levels of competition who gain the physical, social, and psychological rewards that football provides, many interested stakeholders continue to ask, "Is football safe?" Although there are only approximately 1,700 players on National Football League (NFL) rosters, the injuries they sustain have garnered the most attention-and criticism-from the national media. Increased public awareness of the injury potential football possesses has led to an open debate and a major shift in public sentiment over the past 5 years...
