A sleep pattern analysis and visualization system to support people with early dementia

Sleep disturbances are among the most distressing of all Alzheimer´s disease related symptoms. In some cases, however, the sleep disturbance may be a marker for early Alzheimer´s disease. In this paper we present a sleep pattern detection and visualization system developed to support the monitoring of sleep patterns and assessment of sleep disturbances for people diagnosed with dementia, at the early stages of the disease. The system provides visual tool kits for caregivers to view the sleep profiles and for investigators to analyse sleep patterns based on sensory data gathered at users´ home via the telecare service.
