Brief Summary:
The purpose of this study is to measure the amount of a protein in the brain known as tau using an imaging procedure called Positron Emission Tomography (PET/CT). 18F-AV-1451 is a specialized radioactive PET imaging agent that is able to detect the presence of tau in the brain. In this study, the investigator will use the 18F-AV-1451 to capture images of tau in the brain. Findings from this study will likely provide insight into the mechanisms and distinctions of age-related cognitive decline and that of very early Alzheimer's disease.

Group/Cohort Intervention/treatment
Normal Controls and MCI
All subjects will receive 18F-AV-1451 PET scan.
Drug: the radiotracer 18F-AV-1451
Subjects will receive a single IV bolus injection target dose of approximately 370 MBq (10 mCi ± 20%) of 18F-AV-1451 At approximately 75 minutes post dose, scanning will begin. An approximately 30-minute acquisition (six 5 minute intervals) will be performed

Primary Outcome Measures :
  1. Examine uptake of 18F-AV-1451 in the medial temporal lobe (MTL) and its relationship with high-resolution structural and functional MRI measures of MTL subregions. [ Time Frame: 2 years. ]
    Specific analyses will include quantitative measures of 18F-AV-1451 within the medial temporal lobe (MTL) and its relationship to volume and thickness of MTL subregions measured with high-resolution MRI.

Secondary Outcome Measures :
  1. Determine relationship to clinical, cognitive, and other biomarker data [ Time Frame: 2 years. ]
    Correlation and regression analyses will be performed to determine relationships between 18F-AV-1451 and cross-sectional and longitudinal measures acquired as part of each individuals participation in the NACC longitudinal cohort study, including, but not limited to, MRI imaging, neurocognitive testing, demographic information, genetic data, and clinical outcomes.
