Eye exam shows promise in predicting Alzheimer's decades before symptoms

ST. LOUIS  Using an easy eye exam, researchers at Washington University of Medicine in St. Louis were able to detect evidence of Alzheimer's disease in patients before they had symptoms of the disease.

The findings, involving 30 patients, were published today in the journal JAMA Ophthalmology.

Scientists estimate that Alzheimer's-related plaques begin accumulating in the brain two decades before the onset of symptoms.
