Brief Summary:
This study will characterize tau tracer retention by Positron Emission Tomography (PET) as a function of amyloid levels transversally and longitudinally.
Detailed Description:
CROSS-SECTIONAL OBJECTIVES
* To measure 18F-RO6958948 retention in selected participants of ALFA-related studies as a function of amyloid levels.
* To study the relation between 18F-RO6958948 retention and amyloid levels.
* To characterize imaging correlates as a function of tau and amyloid levels.
* To study the role of tau retention on cognitive performance.
* To define predictors of tau retention.
LONGITUDINAL OBJECTIVES
* To measure tau accumulation and spreading in participants of the ALFA-related studies of BBRC as a function of baseline amyloid levels.
* To study the dynamic relation between tau spreading and amyloid levels longitudinally.
* To define predictors of tau spreading.
