| Research Abstract |
First study investigated the environmental condition of lighting intensity at a long-term care facility, especially focusing on places where demented elderly with sleep pattern disturbances spend their daily time. The result of this study suggested that assessing the environmental condition of lighting intensity, utilization of natural lighting based on the characteristics of the facility, and frequency of outside activities were important for one aspects of care adjusting lighting environment of demented elderly with sleep pattern disturbances.
Second study investigated the assessment method of sleep-awake patterns of elderly with dementia. The result suggested possibility of observational method for making wrong assessment when subjects were staying in bed quietly with their eyes close, or when subjects' awakening patterns were shorter than observational intervals. It was also found that actigraphs tend to detect involuntary movement such as scratching or fumbling blankets as awakening, and static activity as sleeping. It was suggested that subjects' physical activity, involuntary movement, and sleeping fragmentation would be an important factor for selecting an appropriate method of assessing sleep-awake patterns among elderly with dementia.
