Blood test could detect Alzheimer's more than 10 years earlier – study

Changes in levels of a protein might reveal onset of disease long before symptoms appear

Changes in levels of a protein in the blood could help shed light on damage in the brain more than a decade before symptoms of Alzheimer's disease develop, researchers have revealed.

While there is no drug to stop the progression of Alzheimer's, or cure it, the researchers said the study findings could be used by doctors to help anticipate when patients might start to show symptoms of the disease.
