It begins twenty years before anyone notices.

You watched it take someone. Solenna is a dementia risk-reduction system: a free profile of your modifiable risk factors, a short daily routine built from it, and a dated record of what you actually did — one you can print for your doctor. Not a brain game. A record.

How it works

Solenna is an evidence-based dementia risk-reduction system — your risk factors, a daily routine built from them, a log of what you actually did, and a record that grows for as long as you keep it.

ProfileThree minutes, 14 risk factors. Free.
RoutineYour top levers, as one short daily practice.
LogWhat you actually did, and your blood pressure.
RecordMonths and years of it, in one place.
ReportPrint it and bring it to your own doctor.

Informed by the twenty-year ACTIVE trial and the full set of modifiable risk factors — because no single habit does the work on its own.

We say reduce risk and delay onset — never prevent, never cure. Solenna informs; it doesn't diagnose.

“I reviewed the risk profile, brain workout, and dashboard screens against the evidence claims and disclaimer language as of August 19, 2026.”

She reviewed the tool, not this page. She found nine problems. We fixed all nine and published her findings in full, alongside four bigger questions still open. Read the review
