Simple Eye Test Could Identify Dementia Risk

Eye test could determine risk of developing dementia

Neuroscientists at Cedars-Sinai Medical Center have determined that "a simple eye test may be able to inform doctors whether or not someone is developing dementia, and even track its progress years before symptoms show," according to IFLScience.com.



The amyloid-beta plaques that play a role in the development of Alzheimer's also build up around the retina of the eye. Not only that, but the researchers also found that the plaque amount found in the retina correlated with the amyloid-beta deposits found in the brain. 



"The findings suggest that the retina may serve as a reliable source for Alzheimer's disease diagnosis," lead researcher Maya Koronyo-Hamaoui said. "One of the major advantages of analyzing the retina is the repeatability, which allows us to monitor patients and potentially the progress of their disease."



While there still currently is no cure for Alzheimer's or dementia, and aging remains the biggest risk factor, tests such as this one can allow doctors to monitor the progression of the disease. For the time being, remaining active - both mentally and physically - refraining from smoking and excessive drinking, and eating a healthy diet and maintaining a healthy weight are the best way to combat dementia.
