A team of neuroscientists from the Washington University School of Medicine (MO, USA) have revealed that a blood test for Alzheimer’s disease may be moving closer to reality. In the study, which has been published in Neurology, the researchers demonstrated that levels of amyloid-β (Aβ) in the blood can be measured and used to predict whether the protein has accumulated in the brain. In addition to this, the investigators stated that when blood amyloid levels were combined with two major risk factors – age and the presence of the genetic variant APOE4 – that people with early Alzheimer’s brain changes...
