Taken once, the Index provides a snapshot of a person’s current brain fitness level.
Taken periodically year after year, it shows an individual’s change and improvement.
The Index score is not based on typical limits or standards (like 100) because there is no known ceiling on brain health. It does not define ranges because its purpose is not to compare people or groups. It shows how an individual’s brain health and fitness can change and improve over time – it’s you against you.
This figure shows a sample of an individual’s overall BrainHealth Index score as well as the changes in the factors that contribute to the global score over time. The degree to which each of the factors contributes can change over time, with the growth in this case being largely due to gains in clarity.
