Beta amyloids are typically found in the brain and have been known to be linked to alzheimers. Dr. James galvin is a neurologist at New York University langone medical center. What makes it unique is that the retina is actually an extension of the brain. And so we think that a lot of the pathology that is occurring in the brain may also be occurring in the retina. Reporter australian researcher sean frost tested 40 people using a liquid form of curcumin the natural substance that makes curry yellow. Curcumin sticks to Beta Amyloids allowing doctors to spot the proteins with a simple eye test. Frost found that the test positively identified 100 of the participants who had alzheimers. Alzheimers so far is just is incurable. So why is it important to be able to detect it . Well, for several reasons so we have medicine today that treats the symptoms of the disease so you would like to be able to pick up the disease as soon as possible so you can start someone on an available medicine, but more importantly in order to develop new therapies we need to be able to identify people at the earliest possible stages. Reporter currently the disease is detected through spinal taps or pet scans which are invasive, expensive and not readily available. The developers of the eye test say it can predict the onset of alzheimers 15 to 20 years before clinical diagnosis. The full study involving 200 subjects is expected to be completed later this year.
