This research study is looking for early signs of Alzheimer's disease by examining tear samples. Tears contain tiny proteins and other molecules that may reveal whether someone has Alzheimer's disease or is in the early stages of memory loss. By studying tears from patients with Alzheimer's, people with mild cognitive changes, and healthy volunteers, researchers hope to develop a simple, non-invasive way to diagnose the disease earlier.
Currently, diagnosing Alzheimer's requires painful spinal taps or expensive brain imaging, which many patients cannot tolerate or cannot access. This study aims to find a simple alternative—analyzing tears—that could make early diagnosis easier, faster, and available to more people.

Your participation would involve a single visit where researchers collect a small tear sample from your eyes using a simple, painless method. You may also have a brief conversation about your memory and health history. The entire visit typically takes less than an hour, and there are no medications to take or follow-up visits required.
