New research by Australian scientists has demonstrated that a quick, non-invasive eye scan can identify changes in the retina that could be used to diagnose Alzheimer’s disease. In a world-first, the team led by Associate Professor Peter van Wijngaarden and Dr Xavier Hadoux from the Centre for Eye Research Australia and University of Melbourne, has used specialised eye scanning technology to detect people with early Alzheimer’s disease. The research, published today in Nature Communications shows that the eye test can accurately identify people with high levels of amyloid beta, a protein that accumulates in the brain and retina in people with Alzheimer’s disease up to 20 years before the onset of symptoms. Associate Professor van Wijngaarden said the findings could pave the way to a new diagnostic test for Alzheimer’s disease and may allow earlier detection of people at risk. Current tests for the disease include spinal fluid tests […]
