To objectively quantify long-term nocturnal physiological and behavioral alterations in Alzheimer's disease using contactless longitudinal home monitoring.
Compared a cohort of 83 individuals with Alzheimer's disease to 13,588 individuals from the general population.
Collected longitudinal sleep patterns, heart rate, and breathing rate using an under-mattress contactless pressure sensor.
Applied data reduction and explainable machine learning approaches to discover distinct sleep phenotypes and derive a clinical index.
Alzheimer's disease was characterized by increased time in bed, more frequent bed exits, decreased snoring, and altered sleep state distributions.
Established the Dementia Research Institute Sleep Index for Alzheimer's Disease (DRI-SI-AD) as a digital biomarker capable of detecting disease progression and acute clinical events at the individual level.
