  1. Retinal Imaging May Predict Alzheimer's Risk Years Before Symptoms

    Researchers believe the eyes provide a window into brain health. Simple photographs of the retina and AI analysis may identify early signs of Alzheimer's disease. These changes could appear years before memory loss begins.

    What's confirmed:

    • Retinal photographs may reveal the risk of early Alzheimer's disease.
    • Subtle changes in the outer retina could help identify Alzheimer's years before memory loss occurs.
    • AI and retinal photos can be used to predict early Alzheimer's risk.
    • Alzheimer's disease is the most common form of dementia.

    Still unconfirmed:

    • OCT-A biomarkers point to early changes in Alzheimer disease and cognitive decline.
    • Deep learning-derived phenotypes link ophthalmic imaging to cardiovascular and neurological traits.
