The National Institute on Aging (NIA) initiated amyloid PET imaging with Pittsburgh compound B (PiB) in the Baltimore Longitudinal Study of Aging (BLSA) in 2005 and tau PET imaging with AV-1451 (T-807) in 2016. Consistent with autopsy data from BLSA and other studies, approximately 30% of cognitively normal individuals have detectable amyloid deposition in the brain on PET-PiB imaging. Individuals with higher levels of β-amyloid are older, more likely to carry the Apolipoprotein E ε4 allele, have greater longitudinal decline in memory and other cognitive functions, and are more likely to accumulate amyloid over time. In addition, through the BLSA autopsy program, NIA has shown the correspondence between in vivo imaging and post-mortem values of amyloid burden (13,18). Workby our group has been central to defining the relationship between amyloid burden and memory change (17,23), to characterizing the magnitude and spatial pattern of progression of amyloid burden (2,4,7,11,16), to highlighting the importanceof individuals with intermediate amyloid levels that would be considered PiB negative in many binary classification schemes (7,16), and to identifying modifiers of amyloid burden (3,7,9,10,12,20,21). The NIA has also developed an approach for estimating age at onset of amyloid accumulation, providing an individualizedindex that can be used as a dependent outcome to assess factors that may modifyage at onset of amyloid accumulation (4). This approach was applied to demonstrate that Apolipoprotein E ε4 genotype is associated with earlier age of onset of amyloid accumulation in the BLSA sample.
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, the NIA has 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 thatmay 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, the NIA has been collecting in vivo measures of brain amyloid and tau, the hallmark pathologies of AD, using PET scanning.
PURPOSE AND OBJECTIVES:
The objective of this requirement is for a better understanding of "age-related" changes also requires definition of the various neuropathologies that accumulate in conjunction with advancing age. NIA collects detailed neuroimaing, as well as cognitive measures in BLSA study participants. NIA acquires measures of regional brain volume (MPRAGE) and vascular lesion burden (T2, FLAIR), white matter integrity (DTI), and functional networks (resting state functional MRI). In alimited number of BLSA participants, NIA also acquire measures of amyloid and tau through PET molecular imaging. The longitudinal assessment of these differentmodalities will provide insights into the neurobiological underpinnings of bothdiseases and age-related cognitive changes. In particular, this information will answer the question of whether accumulating neuropathologies fully account forage-related cognitive change or if there is some degree of age-related cognitive decline that is intrinsic to the aging process, i.e. "normal aging."
Specifically, the purpose is to acquire services to perform and quantify in vivo brain scans, including amyloid and tau neuropathology and regional cerebralblood flow, using Positron Emission Tomography (PET) in the BLSA. Studies of changes in amyloid deposition will be conducted using PET and 11C- Pittsburgh Compound-B (PiB) and studies of changes in tau pathology will be conducted using PETand 18F-T807 from Avid Pharmaceuticals (Lilly).
The following are two goals to satisfy NIA's objective fully:
1. Investigate changes in brain function and amyloid and tau burden as earlybiomarkers of cognitive decline and impairment including Alzheimer's disease.
2. Identify possible protective factors which prevent or delay the onset of cognitive
impairment in individuals who maintain normal cognition despite substantial amyloid and
