Illustrative ranges. Your physician sets yours.
(01) How it’s done
On the day
A thirty-minute set of computer tasks on reaction time, memory and attention, done in a quiet room after lunch.
There is nothing to revise and no pass or fail.
(02) Why it matters
What it tells us
The first test gives you a baseline. What matters is how it changes over the years, measured the same way.
We read it with your sleep, blood pressure, hearing and MRI, which all affect how the brain ages.
(03) Same system
Brain & sleep
Measured on the same day, read by the same physician.
