简要总结
The purpose of this study is to learn about the possible benefits of aerobic exercise in controlling or reducing the amount of amyloid present in the brain, reducing changes in brain structure that may lead to Alzheimer's Disease (AD), and increasing cognitive ability in individuals that have amyloid deposits and are at risk to develop AD.

结局指标
主要结局
Amyloid Burden
时间窗: Baseline to 52 weeks
Amyloid burden measure is mean Florbetapir cortical-to-cerebellar uptake ratio averaged across 6 regions of interest (frontal, temporal, parietal, anterior cingulate, posterior cingulate, and precuneus). Higher numbers mean more amyloid accumulation. There is no defined maximum value. Zero is the theoretical minimum value.
次要结局
