Dynamic Light Scattering Ocular Measurement in the Detection of Dementia

This study uses a non-invasive eye measurement technique called dynamic light scattering to detect signs of dementia. The eye may reflect changes in proteins linked to Alzheimer's disease, and this test could potentially serve as an early screening tool without requiring brain scans or spinal fluid tests. **You may be eligible if...** - You are able to have a basic eye examination and cooperate with the testing - Your eye media (cornea, lens, vitreous) are clear enough for accurate measurements - You are able to have your pupils dilated - You are able to provide informed consent **You may NOT be eligible if...** - You are unable to cooperate with eye testing - Your eyes have significant cloudiness (e.g., severe cataracts) that would interfere with measurements - You are unable to provide informed consent Talk to your doctor to see if this trial is right for you.
