An eye test could predict whether someone could have Alzheimer’s disease years in advance, according to a recent study.
Researchers from Cedars-Sinai and company NeuroVision Imaging found the disease affects the retina, which is the back of the eye, in a similar way to how it impacts the brain. Through this discovery, researchers conducted a noninvasive eye scan in an effort to detect key signs of Alzheimer’s before patients began experiencing symptoms of the disease.
The study, which was published Tuesday in JCI Insight, said a high definition eye scan was able to see the plaque in the retina, which correlated with the amount in the brain. The plaque is a buildup of toxic proteins called amyloid-beta deposits, which are key signs of Alzheimer’s. Build up in the brain may occur as early as two decades before people begin to experience signs of the disease.
