We got access to MRI scans from numerous people with Alzheimer's disease or MCI (mild cognitive impairment) who happened to have an MRI scan up to 15 years ago, when they were still cognitively healthy, and our software detects abnormality in those older scans with a very high accuracy.

The biggest challenge is the huge skepticism in the medical community towards any novel technology related to Alzheimer's disease, given all prior failed big claims by others.
