Background: The BLSA was initiated in 1958 and is a multi-disciplinary study of physiologic and psychologic aspects of normal aging in community-dwelling men and women. Since 1994, we have been conducting a longitudinal brain imaging study of selected older adults in the BLSA to characterize individual differences in longitudinal brain changes, to investigate the extent to which these brain changes underlie individual differences in cognitive aging, to identify brain changes that may be predictors of cognitive decline and Alzheimer’s disease (AD), and to assess the impact of potential modulators of brain and cognitive aging. More recently, we have been collecting in vivo measures of brain amyloid and tau, the hallmark pathologies of AD, using PET scanning. The purpose of this acquisition is to acquire FDA- approved second generation tau PET imaging radioligand to perform in vivo Positron Emission Tomography (PET) scans to measure brain tau neuropathology in BLSA participants on a combined PET/computed tomography (CT) scanner.
