Description:
This study aims to establish, use, and extensively share a comprehensive longitudinal resource of genetic, non-genetic, and cognitive data, brain imaging and fluid biomarker measurements of amyloid-β, tau pathophysiology, neurodegeneration, and inflammation and biological samples to advance the study of cognitively unimpaired older adults at six levels of genetic risk for Alzheimer"s disease due to their APOE genotype including understudied APOE2 and APOE4 homozygotes (HMs) at the lowest and highest risk and those APOE4 HMs and heterozygotes (HTs) who remain unimpaired at older ages due to unknown protective factors and spared pathophysiological effects despite their genetic risk.
