A blood test that helps detect early signs of Alzheimer’s disease, when combined with measures of two major risk factors, identifies early brain changes with a 94% level of accuracy, researchers have found.
The blood test can precisely detect amyloid beta protein, a telltale sign of these brain changes.
A patient’s age and the presence of a genetic marker can then be factored into the diagnosis to boost the test’s accuracy to 94%, according to a recent Washington University School of Medicine study.
Study findings were published Aug. 1 in the journal Neurology.
