Universal blood test for Alzheimer's and mild cognitive impairment developed

An international research team, led by the Hong Kong University of Science and Technology, has developed a universal blood test for Alzheimer's disease (AD) and mild cognitive impairment (MCI). The test shows over 96% accuracy for AD and 87% for MCI, and measures 21 protein levels. It has been tested across different ethnic groups and can detect brain amyloid pathology. The test is expected to aid in early detection and personalized treatments.
