Single Brain Scan May Predict Dementia Risk Early
A new MRI-based brain scan, DunedinPACNI, may predict dementia risk and biological ageing years before symptoms appear. Developed using long-term health data, the scan identifies “fast agers” who face significantly higher risks of dementia, chronic illness, and early death. Researchers say the tool could enable preventive interventions in midlife, such as improving diet, sleep, and exercise. Though still under clinical development, the scan could become part of future routine health screenings, marking a shift toward proactive healthcare.
