Researchers in Australia have identified 9 blood-based biomarkers that correspond with PET imaging measurements of amyloid beta protein, a brain plaque that can signify the advance of Alzheimer's disease. A team from the country's Commonwealth Scientific and Industrial Research Organization, or CSIRO, accomplished this by drawing on data from 23 people who participated in the Australian Imaging, Biomarkers and Lifestyle study of aging. They also used a detailed mathematical model to process the information. The next step: the development of a blood test that would screen for these biomarkers in the hopes of diagnosing the disease in the early stage, allowing for earlier intervention with a potential treatment.
