Eye test may forecast Alzheimer’s risk Two decades before symptoms emerge

A new study by a team of American researchers claims that an eye test can predict the devastating Alzheimer's disease as many as twenty years before its symptoms emergence. Led by Dr. Maya Koronyo-Hamaoui from Cedars-Sinai Medical Center in Los Angeles said that their study suggested that a person’s retina might serve as a trustworthy source for diagnosis of Alzheimer's disease.

After making a comparison between their results and brain scans, they found that the eye test was as successful at detecting those with double the quantity of plaque build-up in their brains.

The researchers underlined that the eye test is the first sign of an affordable as well as non-invasive test.

Dr. Koronyo-Hamaoui, the lead author of the study, said, “One of the major advantages of analysing the retina is the repeatability, which allows us to monitor patients and potentially the progression of their disease.”

Researchers from NeuroVision Imaging, Commonwealth Scientific & Industrial Research Organization, and University of Southern California also participated in the study.

The researchers reported their new study in the most recent edition of the journal JCI Insight.
