Could a blood test detect Alzheimer’s before symptoms appear?

Researchers from the Washington University School of Medicine (MO, USA) and the German Center for Neurodegenerative Diseases (Tübingen, Germany), have demonstrated that a simple blood test may detect signs of Alzheimer’s disease (AD) years before individuals present noticeable symptoms such as memory loss. This could potentially become a useful diagnostic tool, not only for AD, but for other neurodegenerative conditions, or for suspected brain injuries after head trauma.
