Read our Alzheimer Disease research guide →This research study is investigating why people who are overweight or obese in midlife face higher risk for Alzheimer's disease. Researchers will use advanced brain imaging and blood tests to look for early signs of brain damage and inflammation in three groups of people: those who are overweight or obese with metabolic problems, those who are overweight or obese but metabolically healthy, and those who are lean and healthy. The goal is to understand the hidden mechanisms that may link body weight to Alzheimer's risk.
Scientists know that being overweight or obese in middle age increases Alzheimer's risk, but they don't yet understand why or how this happens. This study aims to identify the specific brain changes and inflammatory processes that might explain this connection, which could eventually lead to better prevention strategies.

You likely don't qualify if…
If you qualify, you will visit the research center for metabolic testing, including fasting blood draws and an oral glucose tolerance test to measure how your body handles sugar. You will also undergo two MRI brain scans and PET scans that use radioactive tracers to detect Alzheimer's-related changes in your brain. The entire process involves multiple visits and several hours of testing, but no medications or long-term lifestyle changes are required — the study is observational, meaning researchers are watching and measuring rather than treating you.
