New guidelines propose early Alzheimer's diagnosis via biological markers
Summary: New guidelines from the Alzheimer’s Association propose diagnosing Alzheimer’s disease (AD) based on biological markers, even before symptoms appear. A blood test can now detect brain changes up to 15 years prior to cognitive decline. While this approach aims to improve early detection, concerns arise about potential stigma, insurance discrimination, and the implications of labeling asymptomatic individuals as having AD. Current treatments are not validated for asymptomatic patients.
