Your Vision Can Predict Dementia 12 Years Before Diagnosis

The eyes may serve as early indicators of cognitive decline, as evidenced by a study involving over 8,600 individuals in Norfolk, England. Visual sensitivity loss, detected through a simple test, predicted dementia onset up to 12 years before diagnosis. This connection is attributed to the impact of Alzheimer ‘s-related brain changes on visual processing. Moreover, deficits in recognising faces and inhibitory control of eye movements also signal cognitive decline.
