A Single Brain Scan Halfway Through Your Life Can Reveal How Fast You're Aging

A groundbreaking new tool, DunedinPACNI, can look at a single brain MRI taken at age 45 and accurately estimate your biological aging rate—called the Pace of Aging—years before symptoms appear.

🔍 **In this video, you’ll learn:**

1. How scientists from Duke, Harvard, and Otago created a model using MRI features like cortical thickness, brain volume, and ventricular size to predict aging speed from one scan.

2. Why this beats other aging clocks—it’s based on decades of longitudinal health data, including blood pressure, metabolism, immune function, and more.

3. What a faster DunedinPACNI score means: increased risk of dementia (up to 60% higher), heart attacks, strokes, frailty, cognitive decline, and even earlier death.

4. Its validation in datasets across the U.S., UK, Canada, and Latin America—including UK Biobank, ADNI, BrainLat—showing consistency across populations.

✅ While it’s not yet common in clinics, DunedinPACNI could revolutionize preventive health—giving people time to act before age-related diseases strike.
