Brain imaging study to detect early Alzheimer's protein buildup

This research study uses two specialized brain imaging techniques to detect early signs of Alzheimer's disease in cognitively normal people. The first scan looks for buildup of a protein called amyloid in the brain, which is thought to be an early marker of Alzheimer's. The second scan measures how the brain is using glucose (sugar) for energy. Together, these scans help researchers understand how the disease develops before symptoms appear.

Alzheimer's disease develops slowly over many years, often without obvious symptoms at first. By studying people who still have normal thinking and memory, researchers hope to identify early warning signs and better understand how the disease progresses, which could eventually lead to earlier treatment or prevention strategies.
