Researchers such as Dr. Christine Greer and Dr. Richard Isaacson, both from the Institute of Neurodegenerative Disease in Boca Ratan, FL, have been exploring how the eye may help diagnose Alzheimer’s before symptoms begin. The disease is well advanced by the time memory and behavior are affected. It starts in the brain decades before the first symptoms of memory loss. Because you can see directly into the nervous system by looking into the back of the eye, toward the optic nerve and retina, you can see signs of cognitive decline earlier. If doctors can identify Alzheimer’s in its earliest stages, people could make healthy lifestyle choices and control their modifiable risk factors, like high blood pressure, high cholesterol, and diabetes. Also, findings may eventually lead to the development of imaging techniques that allow us to diagnose Alzheimer’s disease earlier and more accurately and monitor its progression noninvasively by looking through the eye.
