项目摘要

Project Summary/Abstract The long-term objective of this proposal is to increase the accessibility and affordability of hearing loss treatment for older adults with hearing loss and mild cognitive impairment (MCI) or Alzheimer’s disease and related dementias (ADRD) by improving our knowledge base of speech perception abilities in this population and directly translating that knowledge into a tailored approach to hearing intervention. Age-related hearing loss (ARHL) in persons with MCI or dementia may exacerbate dementia-related symptoms such as depression, apathy, agitation/aggression. Moreover, engagement and activity participation are recognized as critical aspects of dementia care management, but those individuals who also experience ARHL are at a disadvantage. The aims of this proposal include basic science investigation as well as refinement and pilot testing of a behavioral communication intervention. Aim 1 will focus on controlled laboratory measures of speech perception abilities in complex background noise as well as the ability to benefit from common communication repair strategies in groups of older adults with MCI/early stage dementia and older adults matched with these individuals for age and hearing thresholds. This aim will improve our theoretical understanding of speech perception abilities for older adults with cognitive impairment. The investigations undertaken in Aim 2 will focus on assessing and defining the functional burden of ARHL and cognitive impairment in group care settings for older adults. A mixed methods approach will be undertaken in Aim 2 to better understand how the quantitative aspects of the prevalence of ARHL and cognitive impairment interact with the acoustic environment as well as the behavioral/social context of staff and peer interactions in the group care setting. Finally, the multicomponent hearing care intervention to be tested in Aim 3 includes acoustic modifications, staff training, and non-custom personal amplification use with target individuals in a group care setting. This feasibility study will lead to the refinement of the intervention protocols to be used in a future grant application that will test the real-world efficacy of the intervention in a cluster- randomized control trial. Dr. Sara Mamo is a tenure-track Assistant Professor in the Department of Communication Disorders in the School of Public Health and Health Sciences at the University of Massachusetts Amherst. With this Mentored Patient-Oriented Research Career Development Award, Dr. Mamo intends to develop methodological skills related to testing speech perception and improve her knowledge base in the theoretical underpinnings of behavioral interventions, the evidence-based approaches to clinical management of dementia, and statistical analyses of longitudinal outcomes. These key training components will support the development of a hearing care intervention that can be integrated into comprehensive care of older adults with cognitive impairment, and measure the long-term downstream effects associated with the intervention in future randomized trials.

项目摘要/摘要该提案的长期目标是增加听力损失的可访问性和负担能力接受听力损失和轻度认知障碍（MCI）或阿尔茨海默氏病的老年人治疗相关痴呆症（ADRD）通过提高我们在这个人群中的语音感知能力的知识基础并将这些知识直接转化为量身定制的听力干预方法。与年龄有关的听证会 MCI或痴呆症患者的损失（ARHL）可能会加剧与痴呆相关的符号，例如抑郁，冷漠，躁动/侵略。而且，参与和活动参与被认为痴呆症护理管理的关键方面，但是那些也经历过ARHL的人处于劣势。该提案的目的包括基础科学调查以及改进和飞行员测试行为交流干预。 AIM 1将专注于在复杂背景噪声中的受控实验室语音感知能力的测量以及在老年人中获得共同沟通修复策略的能力 MCI/早期痴呆症和老年人与这些人的年龄和听力阈值相匹配。这 AIM将改善我们对认知老年人语音感知能力的理论理解损害。 AIM 2进行的调查将重点放在评估和定义功能性伯恩在老年人的小组护理环境中，ARHL和认知障碍的脑袋。混合方法方法将是在AIM 2中进行，以更好地了解ARHL患病率的定量方面如何认知障碍与声学环境以及员工的行为/社会环境相互作用小组护理环境中的同伴互动。最后，要测试的多组分听力护理干预措施 AIM 3包括声学修改，员工培训和针对目标的非定期个人放大用途在集体护理环境中的个人。这项可行性研究将导致干预方案的完善将在未来的赠款应用中使用，该应用程序将测试集群中干预的现实效率 - 随机对照试验。萨拉·马莫（Sara Mamo）博士是传播障碍系的终身任期助理教授马萨诸塞州阿默斯特大学的公共卫生与健康科学学院。有了这一指导 Mamo博士打算发展方法学技能，以患者为导向的研究职业发展奖与测试语音感知有关，并在理论基础上提高她的知识基础行为干预措施，基于证据的痴呆临床管理方法以及统计纵向结果的分析。这些关键的培训组件将支持听证会的发展可以融入认知障碍的老年人的全面护理护理干预措施，以及测量与将来的随机试验中的干预相关的长期下游效应。
