Eye Test May Detect Alzheimer's Years Ahead Of Diagnosis

(Undated) -- An eye test may be able to identify people who have Alzheimer's years before they are actually diagnosed. The test detects proteins known as beta amyloids. Dr. Heather Snyder with the Alzheimer's Association says those beta amyloids are often found in the brain and have been linked to Alzheimer's. Detecting the brain-wasting disease at an early stage could help researchers develop new therapies for treating Alzheimer's patients. The initial findings from an Australian study show the eye test was able to identify every participant who had Alzheimer's.
