Eye Test May Detect Alzheimer’s Early

A simple eye test may one day be able to detect Alzheimer’s disease decades before symptoms develop, according to new research.

A study of patients with the devastating form of dementia found they had more than twice as much of a telltale brain protein in their retinas, the New York Post reports.

Scientists believe this process begins decades beforememory lapses and other symptoms develop, which offers a window for early treatment when drugs and lifestyle changes are likelier to work.

It also opens the door to an inexpensive screening test to identify those most at risk who would then undergo more extensive scanning.

The non-invasive technique uses the fluorescence of curcumin, the main chemical in the curry spice turmeric, to light up amyloid deposits at the back of the eye. Scientists believe the protein is one of the hallmarks of Alzheimer’s.
