African Americans are more than twice as likely to have Alzheimer’s disease/Alzheimer’s disease related dementias (AD/ADRD) as Whites. This is a preventable gap. The simple yet innovative long-term vision of this LEADR proposal is to erase racial disparities in AD/ADRD burden. In this project, we will 1) develop a measure of structural discrimination and resilience, 2) use it to predict outcomes in AD/ADRD and 3) develop interventions to decrease prevalence and increase resilience. Understanding how to equalize the Black and White AD/ADRD burden will reveal mechanisms that will optimize prevention and care for all. With historical data, innovative approaches, and a commitment to addressing this disparity, we can achieve this objective. The functional impact of AD/ADRD is never due solely to individual decline; it reflects interactions between a person’s decline, their ability to compensate, and the demands of the environment. The resilience to compensate is not just an individual matter, it has many domains including the ability to use remaining intact brain function, coping skills, family support, physical layout of the home, and multiple community and policy factors. Although structural discrimination and resilience are relevant to AD/ADRD and function, there are currently no measurement instruments. We will use the sequential exploratory mixed methods Instrument Design Model in which researchers incorporate key stakeholders into the instrument design process. This instrument will measure eight dimensions of structural discrimination and resilience plus family support, greenspace, and social connection. Zip codes across the lifespan will be used to merge historical data to measure multiple risk or protective factors such as school district funding, environmental toxins, and amount of accessible greenspace. We will construct the instrument with older adults and researchers, cognitively test, pilot test, refine and then field the instrument in national datasets supported by the NIH. The intervention development stage will include: 1) insights from the previous qualitative portions; 2) results of the data collection phase; 3) insights from a larger stakeholder groups of policy makers, researchers, advocates, people living with AD/ADRD and their families to review findings and identify potential intervention mechanisms. This program of work will move beyond individual and family interventions to address the structural determinants of AD/ADRD. Developing a reliable, valid measure of structural racial discrimination, being able to test its role in AD/ADRD, and then to use it as a framework for developing population-level interventions, is a high-risk, high-reward goal - worthy of the NIH investment in AD/ADRD. A significant side benefit is that because many other conditions related to structural discrimination are also on the causal pathway to AD/ADRD, this effort will also enhance our understanding of hypertension, stroke, heart disease, and other inflammatory diseases. The project uses the distinct strengths of the applicant, the outstanding research environment, and existing NIA resources to work towards solving crucial disparities that tax families and society.

非洲裔美国人患阿尔茨海默氏病/阿尔茨海默氏病有关的痴呆症（AD/ADRD）的可能性是白人。这是可预防的差距。该领导提案的简单而创新的长期愿景是消除AD/ADRD负担的种族分布。在这个项目中，我们将1）制定对结构歧视和韧性的测量，2）使用它来预测AD/ADRD的结果，3）制定干预措施以降低患病率并提高弹性。了解如何均衡黑白广告/ADRD燃烧将揭示将优化预防和照顾所有人的机制。有了历史数据，创新的方法以及解决这一差异的承诺，我们可以实现这一目标。 AD/ADRD的功能影响永远不会仅仅归因于个人下降。它反映了一个人的衰落，补偿能力和环境需求之间的互动。补偿的弹性不仅是个人问题，它具有许多领域，包括使用剩余的脑功能，应对技巧，家庭支持，家庭的身体布局以及多个社区和政策因素的能力。尽管结构歧视和弹性与AD/ADRD和功能有关，但目前尚无测量工具。我们将使用顺序探索性混合方法仪器设计模型，其中研究人员将关键利益相关者纳入仪器设计过程。该工具将衡量结构歧视和韧性的八个维度，以及家庭支持，绿地和社会联系。整个生命周期的邮政编码将用于合并历史数据，以衡量多个风险或保护因素，例如学区资助，环境毒素和可访问的绿色空间。我们将与老年人和研究人员一起构建该工具，认知测试，试点测试，完善，然后将该工具放在NIH支持的国家数据集中。干预开发阶段将包括：1）以前定性部分的见解； 2）数据收集阶段的结果； 3）来自较大的政策制定者，研究人员，倡导者，AD/ADRD及其家人的人们的见解，以审查发现并确定潜在的干预机制。该工作计划将超越个人和家庭干预措施，以解决AD/ADRD的结构决定者。对结构性种族歧视，能够测试其在AD/ADRD中的作用，然后将其用作发展人群水平干预措施的框架，这是一个高风险，高回报的目标 - 值得在AD/ADRD上投资。一个重大的辅助益处是，因为许多与结构歧视有关的其他条件也存在于AD/ADRD的灾难性途径上，因此这项工作还将增强我们对高血压，中风，心脏病和其他炎症性疾病的理解。该项目利用应用程序的独特优势，杰出的研究环境和现有的NIA资源来解决征税家庭和社会的关键差异。
