1Measures the regions that matter
The regions affected earliest are measured automatically from a standard MRI. No manual tracing.

The problem
The window that keeps closing
Alzheimer's is most treatable early, and the newest therapies only work at that stage. The signal is already in the MRI, in shrinkage too subtle to quantify by eye.

Each region is placed against a reference population matched for age and sex: the measurement, the normal range, and the percentile.

3Looks forward
A 36-month estimate of progression from MCI to Alzheimer's, from the scan, age, and sex. Cognitive or genetic data refine it.
Why it's different
Not a black box
A score with no reasoning is unusable to a clinician. CeDawn shows the measurement, the normal range, and the regions behind the estimate.

Where we are
Where we are
CeDawn is a research platform. It runs end to end today, and we're validating it with clinical and research partners. It is not a cleared medical device and does not replace clinical judgment. We're building the evidence base for clearance, with research groups like yours.

Building the validation
Building the validation, together
Run CeDawn on your cohorts. You get a novel quantitative measure and progression estimate for your own work, with co-authorship on what comes out of it. Collaborators, not vendors.
