Blood test could predict Alzheimer's 16 years before symptoms begin: Study

A new study could provide hope for future Alzheimer's patients.

Researchers have discovered that a simple blood test could predict if a person will develop Alzheimer's disease up to 16 years before symptoms begin.

The study focuses on a certain protein in the blood. Scientists believe any rise in levels of that protein could be an early sign of Alzheimer's.

The findings could help doctors find more effective treatments.
