A simple blood test could spot Alzheimer's a decade before a person starts to display symptoms, scientists have discovered.
Researchers at Karolinska Institutet, Sweden, found that a type of protein called GFAP could be used as a possible blood-marker for the 'very early' signs of the illness - meaning that it could be identified during a quick blood test.
It often takes years for Alzheimer's symptoms such as memory loss to show up after a person develops the disease. However, diagnosing it earlier on may help slow down the illness with drugs and other medication.
