Blood markers ‘may reveal rare form of Alzheimer’s 10 years before symptoms’

The scientists said their findings, published in the journal Brain, could lead to earlier detection of the disease and help slow it down with drugs

Scientists have discovered blood markers that could help identify people with a rare, inherited form of Alzheimer’s disease a decade before symptoms begin to appear.

Researchers at the Karolinska Institutet in Sweden have found that a protein called GFAP can appear in blood samples of people who are in the very early stages of the neurodegenerative disease.
