For decades, medicine has treated the diseases of aging as if they were separate problems. Treat the cancer, then the heart attack arrives. Manage the diabetes, then Alzheimer's follows. Buck Institute President and CEO Eric Verdin calls this "whack-a-mole medicine" — and argues that the better approach is to target the aging process itself, before diseases appear.1 That requires knowing which organ is setting the pace.
In 2025, Stanford researchers published data from nearly 45,000 people showing that organs age at different rates within the same body — and that brain age is the single strongest predictor of overall mortality. A biologically younger brain reduced the risk of death by 40%. A fast-aging brain increased it by 182%. Roughly 1 in 5 apparently healthy people had at least one organ aging significantly faster than the rest of their body without knowing it.2
The brain isn't just another organ to monitor. It's the one that predicts how long you live, how well you function, and whether you remain the person making your own decisions. BrainYears™ was built to make that organ measurable — while the trajectory can still change.

What Is BrainYears™?
Until now, meaningful brain age measurement required research-grade neuroimaging — expensive, episodic, and out of reach for most clinics, let alone individuals.
BrainYears™ Changes That
Using EEG and ERP — brain responses captured during active cognitive tasks, not just at rest — it calculates your functional brain age, which may be younger or older than your chronological age, and tracks how that trajectory changes over time. Unlike structural imaging, it measures brain function upstream of anatomical decline, when the trajectory is still reversible.
