Metrics to monitor performance of patients with mild cognitive impairment using computer based games

Mild Cognitive Impairment (MCI) results in a noticeable decrease in cognitive abilities but does not interfere with regular daily functions. Some patients with MCI may be able to return to age-appropriate cognitive abilities, but some will progress to dementia. Clinical interviews, tests and measurements are used to identify and monitor cognitive decline. Timely detection of cognitive decline provides an opportunity for early intervention and can improve care and quality of life. Periodic monitoring of the cognitive status of MCI patients in their own environment is a significant and cost effective aid in patient care. This paper presents a methodology and performance metrics for remote monitoring of cognitive ability using computer based Sudoku and word search games. We collected game data for 2 MCI patients from the Bruyére Memory Program over a period of weeks. Their game performance was then compared to results from cognitive testing using the Montreal Cognitive Assessment (MoCA) and the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The patient who performed better on the games also had higher scores on the cognitive testing.
