Cognability — evidence-based cognitive health
Cognability uses cognitive neuroscience and user-centered design to help people track, maintain, and improve brain health.
Around 45% [1] of dementia cases are linked to things you can change.
Cognability turns that finding into something you can actually use: a score across the twelve modifiable risk factors, and a personalised daily plan to move it.
A wellness tool, not a diagnosis. Free while in prototype.

- 1.6%Physical activity
- 1.1%Blood sugar
- 0.8%Alcohol
- 0.7%Weight & waist
Population-attributable fractions, summing to 39.7% of cases.

How it works
Answer 20 questions once
A short questionnaire covering all twelve modifiable factors — hearing, blood pressure, movement, mood, connection and the rest.
Get your Cognability score
A single 0–100 number weighted by the Lancet Commission's population-attributable fractions, with a factor-by-factor breakdown.
Work one factor at a time
Three personalised actions a day and a weekly focus challenge, generated from your own weakest factors.
Built on evidence, not vibes
Every factor, weight and recommendation traces back to the Lancet Commission, WHO risk-reduction guidelines, or a named trial.
Hearing first
The largest single contributor in the Lancet model — 8.2% of preventable risk.
Midlife numbers
Blood pressure, blood sugar and weight, treated from 40 rather than 70.
Connection & mood
Social contact and depression are independent, modifiable and compounding.
Train and track
Cognitive exercises adapted from the paradigms used in MCI assessment.
Cited, always
Every tip in the library carries its source — Lancet, WHO or peer-reviewed trial.
Reserve keeps building
Novel, effortful learning grows cognitive reserve long after school ends.
Start with one factor, not twelve
The questionnaire takes about four minutes. You'll get your score and your first day of actions immediately.
