Sundown Syndrome, Sleep Quality, and Walking Among Community-Dwelling People With Alzheimer Disease

Advanced dementia, poor sleep quality, and shorter weekly duration of walking were the influencing factors of sundown syndrome. Walking with relatives and regular longer walking time could improve sleep quality and alleviate sundown syndrome. It is suggested that a well-designed walking intervention considering these factors could be an appropriate strategy to manage sundown syndrome and sleep quality for PAD and their caregivers.
