A team of researchers in the United States of America has come up with a simple eye test that may be able to detect Alzheimer´s disease, long before a person is infected with the disease.
"The eye can already be a benchmark for the study of degenerative diseases in the nervous system," said Gregory Van Staverne, professor of ophthalmology and visual sciences at the University of Washington.
Stavern researcher added, that "reach the eye and reach the result, easier than reaching the brain to perform the search."
American scientists say that specialists are aware of a person with Alzheimer´s two decades before the disease, i.e. before the onset of symptoms such as amnesia and mood changes, and doctors may recognize the patient with Alzheimer´s by conducting laboratory tests including brain imaging, or a test of memory.
As the American researcher Staverne revealed, these tests take longer as they are very expensive, adding that "A simple eye examination may make us know whether a person is sick or not, in addition," it is believed that people with the disease have a thinner retina and fewer blood vessels. "
