"...Another company, Sacramento, Calif.-based Neurovision, aims to use machine learning to develop retinal scans and blood tests to identify people at risk of developing Alzheimer’s and other forms of dementia. The company's AI model analyzes eye scans for anomalies, like the buildup of certain proteins or blood vessels with a twisted shape, that are associated with Alzheimer’s, said Steven Verdooner, Neurovision's co-founder.
