Imaging [18F]AV-1451 and [18F]AV-45 in acute and chronic traumatic brain injury

The potential long-term effects of Traumatic Brain Injury (TBI) are poorly understood. Repeated concussions have been associated with an elevated incidence of Alzheimer’s disease (AD) as well as chronic traumatic encephalopathy (CTE). There are growing concerns about the long-term neurologic consequences of head impact exposure from routine participation in contact sports (e.g., boxing, football). Brain autopsies of athletes with confirmed CTE have demonstrated tau-immunoreactive neurofibrillary tangles and neuropil threads (known as tauopathy). The relationship between exposure to repetitive head impact and the subsequent development of chronic neurodegenerative disease has not been established. Further, as the diagnosis of CTE (defined by the presence of tauopathy) is presently made at autopsy, clinical tools and biomarkers for detecting it remain to be defined. We aim to determine whether these individuals are on the same trajectory of neurodegenerative disease seen in AD or in CTE. Our study will utilize both [18F]-AV-1451 and [18F]-T807 PET imaging to investigate amyloid and tau accumulation in subjects with a history of concussions. We will obtain MRI, PET, and neurocognitive data in a cohort of 25 subjects with a history of TBIs and a cohort of 25 controls. This dataset currently contains data acquired from two sessions (3.9 years apart) from a single subject, including two T1w scans and two PET scans.
