A digital pen has been used to create a dementia-prediction tool that could diagnose conditions far earlier, and with greater accurately.
Computer scientists looked to a traditional method of screening for cognitive impairments known as the clock-drawing test. The test involves drawing a clock that shows the time to be 11.10, and then copying a pre-drawn clock showing the same time. It demonstrates how people perform when it comes to verbal understanding, memory, and spatial knowledge, and is used as a tool to detect for Parkinson's and Alzheimer's. The team behind the latest digital pen study, however, wanted to find a way to automate the test -- not only to speed up diagnoses, but remove doctor subjectivity and potentially help drive earlier diagnoses by using more detailed data markers.
