Using a non-invasive eye exam, the researchers detected signs of Alzheimer’s in older people before they had developed any symptoms of the disease.
The plaques that occur in the brains of people with Alzheimer’s can start to accumulate up to twenty years before symptoms such as memory loss and cognitive decline develop.
O’Bryhim says the hope is that this new technique could be used to understand who is accumulating these abnormal proteins in the brain that may lead them to develop the disease.
