The Microbiome in Aging Gut and Brain (MiaGB) Study is investigating whether the trillions of tiny bacteria living in your gut may be connected to memory problems and brain aging. Researchers will collect samples from your mouth, saliva, stool, blood, and urine, and will run tests to understand these bacteria and how they may relate to your thinking and memory. The study is following groups of healthy younger adults, healthy older adults, and older adults with memory concerns or Alzheimer's disease.
Scientists believe that the bacteria in our gut may play an important role in how our brains age and whether we develop memory problems. This study is trying to understand those connections so doctors might one day be able to prevent or slow down memory loss.

If you join this study, you'll start with baseline visits where you'll answer questions about your health, diet, and thinking abilities, and provide samples like stool and blood. Depending on which group you're in, you may return once a year for up to 5 years for follow-up visits where the researchers repeat the memory tests and collect new samples. If you have Alzheimer's disease, you'll only do the initial visit with no follow-up.
