There is a pressing need to develop therapeutics that can promote brain health with aging. Such therapeutics would postpone the deterioration in cognition and mental health that occurs with age. The proposed research will identify, optimize, and then test in laboratory animals such therapeutics as steps towards future clinical use. The research focus is on mitochondria, the organelle in brain neurons that provides energy and many other functions for neurons to function and remain healthy. Mitochondria become impaired with age; mitochondrial impairment is one of the well-known hallmarks of aging. In pilot studies, we have identified a few new drugs that have the potential to enhance mitochondrial function across age. We will search for and identify five times more to enlarge the set of potential “mitotherapeutics.” These drugs will then be tested in laboratory animals to determine whether they can protect mitochondria from the insults associated with age and enhance brain function; postponing or eliminating the cognitive and mental health issues that occur with age. Drugs with the potential to postpone or eliminate these issues would have an enormous impact on brain health for the late adult and elderly in the U.S. population.

迫切需要开发能够随着衰老促进大脑健康的疗法。 这项研究将推迟认知和心理健康随着年龄的增长而恶化。 将识别、优化并在实验动物中测试此类疗法，作为未来临床的步骤 研究重点是线粒体，它是大脑神经元中提供能量和许多功能的细胞器。 线粒体发挥作用并保持健康的其他功能会随着年龄的增长而受损； 线粒体损伤是众所周知的衰老标志之一，在试点研究中，我们发现了一些。 我们将寻找并确定有可能在不同年龄阶段增强线粒体功能的新物质。 五倍以扩大潜在的“线粒体疗法”的范围，然后这些药物将在实验室进行测试。 动物以确定它们是否可以保护线粒体免受与年龄相关的损害并增强 大脑功能；推迟或消除随年龄增长而出现的认知和心理健康问题。 推迟或消除这些问题的潜力将对后期的大脑健康产生巨大影响 美国人口中的成年人和老年人。
