Detecting Alzheimer’s early allows for better treatment, and a new test that looks at the eye can make early detection a lot easier. Those with Alzheimer’s have cloudy-looking plaques that are present in the eye long before other signs of Alzheimer’s show.

A Harvard researcher says a laser-based diagnostic system might be used to detect the disease long before it affects the brain, allowing for early treatment that could defer its degenerative symptoms.

Thanks, Justin!
