NEW YORK (Reuters Health) – “Significant” differences in the retina of Alzheimer’s patients can be identified, paving the way for a future in which the disease can be diagnosed by a simple eye examination before the onset of major symptoms, according to a new study. Duke University’s research on non-surgical imaging allowed doctors to quickly check blood flow in small capillaries at the back of the retina. According to the site, the study was conducted on more than 200 people, who were photographed using the technique mentioned, and found that 39 people with Alzheimer’s disease, and 37 suffer slightly cognitive impairment. One of the main goals of the study was to identify any retinal damage that could be directly linked to Alzheimer’s disease, independently of the overall cognitive decline associated with age.
