New test detects dementia in patients nine years earlier

July 2024 An international research team has developed a test which can predict dementia with over 80 per cent accuracy, up to nine years before potential diagnosis. Unlike memory tests or brain shrinkage measurements, this method analyses functional MRI scans to detect changes in the brain’s default mode network, the first neural network affected by Alzheimer’s disease. This approach allows for proactive health-care strategies and earlier therapeutic interventions. The study, led by Professor Charles Marshall from Queen Mary University of London, which also included Associate Professor Adeel Razi from Melbourne’s Monash University, used MRI data from over 1100 UK volunteers, assigning each a dementia probability. The model accurately predicted dementia onset up to nine years in advance, with a two-year margin of error, highlighting social isolation as a risk factor. The research, published in Nature Mental Health, promises to transform early detection and treatment, improving patient out-comes.
