Abstract excerpt

BACKGROUND: Disrupted sleep and circadian rhythms in dementia affect rest-activity patterns and impact quality of life, safety, and caregiver burden. The objective of this study is to extend the application of real-time location system (RTLS) technology from nurse call and elopement prevention systems to measuring digital markers and phenotypes of rest-activity in people with advanced dementia in residential...
