title: The influence of sleep disruption and pain perception on indicators of quality of life in individuals living with dementia at home.
abstract: This cross-sectional study evaluated the influence of sleep quality and pain perceptions on different dimensions of quality of life in community-dwelling persons with dementia. Evaluations of pain were collected using Visual Analog Scale (VAS), sleep disruption using Pittsburg Sleep Quality Index (PSQI) items, and quality of life indicators using the DemQOL-Proxy in 88 persons with dementia and their family caregivers. Lower overall quality of life was associated with the presence of pain and symptoms of sleep disruption when controlling for mental status, age, and number of health conditions. Pain and sleep symptoms were differentially associated with different aspects of QoL. As symptoms negatively impact quality of life but are modifiable, better clinical procedures are needed to prevent and also identify and treat symptoms of pain and sleep disturbance in community-dwelling persons with dementia.
