Detection of cognitive impairment from eSAGE cognitive data using machine learning

Alzheimer’s disease is a neurodegenerative disease that affects many people worldwide. Many cognitive screening tests are available, with one example being eSAGE – a self‐administered exam (Scharre et al., 2017)1. eSAGE is a valid and reliable cognitive assessment tool to detect mild cognitive impairment or early dementia. It has been implemented as an app in BrainTest®, with sample screenshots in Figure 1. While eSAGE provides diagnostic results of its own, there is a potential to apply machine learning methods to the responses to obtain better diagnostic results.
