Development of an at‐home cognitive “vital sign” to detect cognitive changes in Alzheimer's disease

The D-Cog assessment is feasible in clinical practice for AD patients, and patients would be willing to complete the D-Cog remotely while at home. D-Cog scores compare well against standardized pen-and-paper neuropsychological scores but offer the convenience of at-home use and more frequent self-administration. Future work investigating the utility and convenience of the D-Cog as a daily at-home assessment is promising as an accurate measure of cognitive ability, potentially offering early detection of delirium or ARIA.
