Researchers believe that oxidative stress (a type of cellular damage) and nutrition may play a role in how Alzheimer's disease progresses. This study is collecting blood samples and memory test results from people with memory concerns to see if measuring these blood markers can help predict how quickly someone's cognitive abilities will decline over time.
Currently, doctors cannot reliably predict which people with early memory problems will develop Alzheimer's disease or how quickly their condition will worsen. If blood markers can predict this progression, it could help doctors intervene earlier and better tailor treatment plans.

You will have blood drawn once at the start of the study to measure oxidative stress and nutrition markers. You will also complete standard memory and thinking tests (including pen-and-paper tests and possibly an MRI brain scan) during your normal clinic visits. Then, you'll continue with routine follow-up visits about every 6 months for up to 5 years, where researchers will track how your memory and thinking abilities change over time using the same tests.
