Cognoa is an app that asks parents to answer 15 questions about behavior to indicate whether their child is at risk of autism. It is based on data from 10,000 children and validation studies led by Stanford professor Dennis Wall.
The system focuses on specific behaviors from standard diagnostic instruments that have the highest value for detecting developmental delay and autism. The predictive algorithm relies on the behavioral reports from parents and a video evaluation of the child.
It is meant to be used by non-clinicians to earlier identify issues that require treatment by a physician.
