Talk therapy? AI may detect 'earliest symptoms' of dementia by analyzing speech patterns

Chief Washington correspondent Mike Emanuel reports the latest on the new Alzheimer's drug. A new artificial intelligence-powered tool aims to detect signs of dementia, Alzheimer's and other memory disorders by analyzing a person's speech and language patterns. The system is called CognoSpeak. Researchers at the University of Sheffield in the U.K. developed it. In early trials that included both Alzheimer's patients and cognitively heathy people, the tool showed 90% accuracy in identifying those with dementia -- which is just as accurate as "pen-and-paper tests," according to a press release announcing the new tool.
