Imaging Method Detects Alzheimer's Risk

Facebook X LinkedIn Email
LOS ANGELES, Jan. 2, 2007 -- An innovative brain-scan technology shows promise in detecting those at risk for developing Alzheimer's disease, years before symptoms become obvious, by showing in living brains the abnormal protein deposits that can lead to the disease -- something that previously could only be confirmed by autopsy.   Scientists at the University of California, Los Angeles are in the early stages of identifying biomarkers in the blood and spinal fluid to help with Alzheimer's diagnosis, but they said this study is the first to report a real-time "window into the brain" that identifies the major abnormal...Read full article

    biomarker
    A biomarker, short for biological marker, refers to a measurable and quantifiable indicator of a biological condition, process, or response. Biomarkers can be substances or characteristics that are objectively measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacological responses to therapeutic interventions. These markers are often used in medical and scientific contexts to assess health status, diagnose diseases, monitor treatment outcomes,...
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
