Vision
Most people with dementia are never diagnosed, and the tests that exist were not built for every language or every level of schooling. The technology goal at Zero Dementia is to change that: a memory and thinking check that is fair to the person in front of it, clear enough for a clinician to trust, and simple enough to run anywhere.
That means software that explains every score, keeps data private on the device, and adds new signals such as voice and eye movement only after they are validated in clinics. One engine, used in a clinic on a tablet, on a phone for an adult who wants to keep track, and inside the health platforms people already use.
Screen earlier. Healthier tomorrow.
What Raiyan builds
The products Raiyan leads on the technology side.
Engineering principles
Fair by design
Tasks adapt to schooling, reading level and home language, so a person is measured, not their education.
Show the working
Every automatic score explains itself, from a clock drawing to a recall task, so a clinician can check it.
Clinician in the loop
The software proposes; the clinician decides. Missing or declined answers are never scored as zero.
Private by default
Answers and notes are encrypted on the tablet. Voice or eye recordings need their own consent.
Validate before scale
New signals, like voice and eye, go through clinical validation before they touch a decision.
