Dynamic cognitive health from everyday online surveys in dementia research

Who could benefit from this research

What this research studies

This project uses digital survey paradata, like how quickly people answer questions and patterns in responses, to track short-term changes in cognitive functioning in people at risk for dementia. By analyzing over 700 biweekly survey waves from the Understanding America Study, researchers will build time-based profiles of cognitive performance across multiple domains. These dynamic phenotypes aim to reveal subtle fluctuations that traditional one-off tests might miss, helping identify when cognitive health starts to decline. The work continues from an earlier study that showed these response patterns can predict dementia onset, now focused on refining and validating these dynamic measures.
