Experimental: PiB PET, FDG PET, Tau PET |
Drug: Pittsburgh Compound B (C-11 PiB)
Repeat these scans approximately every 24-30 months for up to 10 years in those with all three PETs or 20 years in those with only PiB PET and FDG PET. A second PiB PET, TAU PET and/or FDG PET may be administered within a year if needed to ensure a completed exam for analysis in the rare case of exam failure or data loss. Drug: F-18 FDG Repeat these scans approximately every 24-30 months for up to 10 years in those with all three PETs or 20 years in those with only PiB PET and FDG PET. A second PiB PET, TAU PET and/or FDG PET may be administered within a year if needed to ensure a completed exam for analysis in the rare case of exam failure or data loss. Drug: Tau (18-F-AV-1451)

- To understand the predictive ability of PiB PET imaging for neurodegenerative diseases. [ Time Frame: up to 20 years ]
- Using PiB-PET, to ascertain cross-sectionally the magnitude and the spatial distribution of amyloid deposition in the brain in subjects who are clinically classified as CN, MCI, and demented. [ Time Frame: up to 20 years ]
- To identify the relationship between amyloid burden and the risk of progression from CN at baseline to MCI. [ Time Frame: up to 20 years ]
- To identify the relationship between amyloid burden and the risk of progression from MCI at baseline to dementia. [ Time Frame: up to 20 years ]
- To measure longitudinal change in amyloid burden and cognition and characterize the correlation between change on serial PiB-PET measures vs. FDG measures and concurrent change on continuous measures of cognitive performance. [ Time Frame: up to 20 years ]
