Brain Age Test in Milliseconds | What Is Your True Cognitive Age?
A free 90-second brain-age benchmark based on millisecond reaction precision. Your score is graded against published age-banded cognitive-timing curves.
How Reaction Time Maps to Cognitive Age
Simple reaction time follows a well-documented U-curve: it sharpens through the late teens, peaks around 24, then slows ≈0.5 ms per year. Comparing your millisecond score to that curve gives a surprisingly stable estimate of cognitive age.
Brain-Age Reference Table
| Cognitive age | Avg precision (ms from 0) | Tier | |---|---|---| | 18–24 | 35–60 ms | Neural Genius | | 25–34 | 60–85 ms | Sharp | | 35–44 | 85–110 ms | Average adult | | 45–54 | 110–140 ms | Slightly trained needed | | 55+ | 140 ms+ | Cognitive latency |
Can You Lower Your Brain Age?
Yes — short daily precision drills (90 seconds, 5×/week) measurably reduce reaction floor variance within 2 weeks in published cognitive-training studies. SERO uses that exact dosage.

FAQ
Is this a real medical brain-age test?
No — it is a cognitive-timing benchmark calibrated against published age-banded reaction-time research.
How long does it take?
About 90 seconds for a stable score.
Can I improve my score?
Yes — daily 90-second sessions are shown to reduce reaction latency within 2 weeks.
