Study Summary

The investigators will conduct tau positron emission tomography (PET) scans on 125 adults using the radiopharmaceutical Flortaucipir F18 (\[18F\]AV-1451). This will allow the investigators to determine tau deposition across adults of different ages and assess the relationship of current tau burden to cognitive function and amyloid deposition collected over the previous 10-year interval.

Primary Outcome

Tau accumulation in the temporal lobe will be measured as the standardized uptake value ratio (SUVR) computed from each participant's \[18F\]AV-1451 PET scans averaged across six bilateral regions of interest (ROls) by normalizing regional counts to the whole cerebellum. The 6 ROls are: inferior temporal gyrus, middle temporal gyrus, superior temporal gyrus, entorhinal cortex, parahippocampal gyrus, and fusiform gyrus. Each participant's PET scan and the six bilateral ROIs will be coregistered t
