Dr. Richard Isaacson was featured by CNN discussing emerging research suggesting that changes in the retina may help detect Alzheimer’s disease years before memory symptoms appear. He explained that Alzheimer’s-related changes begin in the brain decades before cognitive decline becomes noticeable, making the search for accessible, noninvasive biomarkers an important step toward earlier diagnosis and intervention.

Dr. Isaacson noted that the retina offers a unique view into the brain and emphasized that identifying Alzheimer’s pathology in its earliest stages could allow people to address modifiable risk factors—including blood pressure, cholesterol, diabetes, sleep, exercise, and nutrition—through personalized prevention strategies. The research adds to growing evidence supporting the role of retinal imaging and other biomarkers in advancing precision medicine and earlier Alzheimer’s risk assessment.
