项目摘要这项拟议中的研究将研究一种名为轨迹的小脑干核团的脑成像标记。蓝斑对认知功能很重要，也是第一个显示阿尔茨海默氏症的大脑区域- 继续下去的老年人中的相关变化会发展成痴呆症。这项研究将检查大脑成像轨迹随着时间的推移有健康衰老经历的老年人和那些衰老的老年人中的蓝斑标记就会患上阿尔茨海默氏症、脑血管疾病和认知能力下降。通过比较弹道对蓝斑的脑成像标记物的变化，我们可以更好地了解这些成像标记物用于从非常早期的阶段跟踪疾病进展。

英文摘要

Project Summary The proposed study will investigate brain imaging markers of a small brainstem nucleus called the locus coeruleus, which is important for cognitive function and is the first brain region to show Alzheimer’s disease- related changes in older adults who go on develop dementia. The study will examine brain imaging locus coeruleus markers in older adults who go on to have a healthy aging experience over time and in those who go on to develop Alzheimer’s disease, cerebrovascular disease and cognitive decline. By comparing the trajectory of changes in brain imaging markers of the locus coeruleus, we can better understand the potential value of these imaging markers for tracking disease progression from a very early stage.
