Alzheimer's Scan

Researchers are developing a laser that scans the eye to detect Alzheimer's in its early stages. The scan shines a low-intensity beam of light into the eye. The beam then reflects back off certain particles producing a "scatter pattern." The pattern is then analyzed, looking for beta-amyloid protein. Beta-amyloid protein builds up into plaque between the nerve cells in Alzheimer's patients. So far, this method has been 100 percent accurate in detecting Alzheimer's in mice.
