TL;DR: Polysomnographic recordings in dogs can detect sleep-wakefulness cycle changes associated with dementia, and their potential clinical use to monitor the progression of canine cognitive dysfunction syndrome is evaluated. (via Semantic Scholar)

IntroductionSleep is fundamental for cognitive homeostasis, especially in senior populations since clearance of amyloid beta (key in the pathophysiology of Alzheimer's disease) occurs during sleep. Some electroencephalographic characteristics of sleep and wakefulness have been considered a hallmark of dementia. Owners of dogs with canine cognitive dysfunction syndrome (a canine analog to Alzheimer's disease) report that their dogs suffer from difficulty sleeping. The aim of this study was to quantify age-related changes in the sleep-wakefulness cycle macrostructure and electroencephalographic features in senior dogs and to correlate them with their cognitive performance.
