MRI Method Predicts Dementia 9 Years in Advance with 80% Accuracy

Researchers developed a method to predict dementia with over 80% accuracy up to nine years before diagnosis. Using fMRI scans, the team analyzed changes in the brain's default mode network (DMN), which is affected early in Alzheimer's disease. This approach outperforms traditional memory tests and brain shrinkage measurements. The study used data from over 1,100 volunteers and highlights potential applications for early intervention.
