Detect Alzheimer's
Up to 15 Years
Before Symptoms Appear
Raah Health is building the world's first home-use brain health monitor. A companion app and a proprietary home device that quietly watches over your brain, continuously, without ever leaving your home.

We're Losing the Battle Against Alzheimer's Because We Start Too Late
The disease begins silently, years before the first memory loss. Yet we have no way to see it coming.
Today's diagnostic tools, hospital MRI scans, PET imaging, and lumbar punctures, are expensive, invasive, and provide just a single snapshot in time. Most people never get one until they are already experiencing symptoms. By then, the disease may have been silently progressing for over a decade.
There is simply no way today for a person to monitor their own brain health at home, continuously, during the years when early action matters most. That is the gap Raah Health was created to fill.
Brain Health Monitoring You Can Do at Home
Two technologies designed to work together, giving you a continuous picture of your brain health over time.
The Raah Health App
How you walk tells a surprisingly detailed story about your brain. Step length, speed, and rhythm are among the earliest measurable signs of neurological decline — associated with Alzheimer's, other dementias, and broader cognitive change — often appearing years before any memory loss. Our app monitors these patterns passively, in the background, as you go about your day.
The Raah Home Device
A compact proprietary device used at home for just a few minutes. Through our novel non-invasive sensing technology, it creates a detailed picture of your brain tissue over time. Combined with your app data, it can detect subtle early changes years before any symptoms appear.
Three Steps to Ongoing Brain Health
Simple by design. Powerful by science.
Download and Start
Download the Raah Health app. It quietly learns your personal walking baseline, no extra effort required.
Build Your Picture
Your Neurological Health Score develops over weeks. When our home device launches, add a quick session for an even deeper view.
Stay Ahead
Watch your trends, share securely with your doctor, and act early when it matters most.
The Science Is Working
We are at an early stage. The foundations are solid and the direction is clear.
Accuracy in early feasibility work across four stages of neurological progression, from healthy to moderate Alzheimer's, using our multi-modal approach
Working mobile apps (iOS and Android) already live and collecting walking data, linked to a secure cloud platform
Disease stages identified: healthy, early concern, early Alzheimer's, and moderate Alzheimer's, enabling nuanced, earlier monitoring
These results come from early-stage laboratory feasibility work and do not represent clinical validation. Raah Health is a pre-clinical research company. No product is currently available for purchase or use. Our devices have not been approved by the MHRA or any regulatory authority.
Help Shape the Future of Brain Health
We are building relationships with clinicians, researchers, and healthcare leaders who believe early detection can change the story of Alzheimer's.
We are seeking advisors with expertise in:
This is an informal advisory role at this stage. We are building relationships with people who share our mission, not filling formal positions.
