Dr. Richard Isaacson was featured by CBS News Miami discussing research suggesting that a simple retinal eye exam may one day help detect Alzheimer’s disease before memory symptoms begin. He explained that because the retina is an extension of the brain, subtle changes in retinal structure may provide an early window into the biological changes associated with Alzheimer’s disease.

Dr. Isaacson highlighted research showing that retinal changes correlate with changes in the brain’s memory centers, opening the door to earlier diagnosis and more personalized prevention strategies. He emphasized that identifying Alzheimer’s-related changes before symptoms develop allows individuals to address modifiable risk factors through targeted lifestyle interventions, precision medicine, and long-term brain health planning. He also discussed the NIH-funded Retain Your Brain initiative, designed to make personalized Alzheimer’s risk reduction more accessible.
