What is a "Brain Performance Age"?
It's a playful way of framing your combined performance across four quick task types — not an assessment of your actual biological age or brain health. Better accuracy across the mix produces a "younger" estimated age; the scale is intentionally illustrative and designed for a shareable result, not a scientific one.
How the score is calculated
Your combined accuracy across all 8 questions maps onto an age range roughly between 18 and 70, using a simple, disclosed formula — see our testing methodology for the exact approach. This test is for entertainment and educational purposes only and should never be read as a medical measurement.
Can this actually measure how "old" my brain is?
No. There is no clinically validated way to measure a single "brain age" from a short online quiz. This test is a fun way to compare performance across a mix of tasks, nothing more.
