Summary

Elderly with dementia living in residential care homes often have limited access to adequate lighting (daylight). Light can however positively impact the individual on a number of factors, including sleep quality and mental health. The proposed non-invasive study seeks to evaluate the impact of an improved lighting environment in the living areas of residential care home residents with dementia on both the physical and mental well-being of these individuals. To assess sleep quality, an actigraphy device will be used from which a number of parameters corresponding to sleep quality can be obtained. Mental health/behaviour of the participants will be assessed by validated questionnaires. These questionnaires will be filled for each participant independently by 2 members of the nursing staff. Two groups of residential care home residents will be observed during this study: an intervention group and a control group. In the intervention group, innovative lighting designs are already implemented in the living area. The control group will experience no significant modifications to their lighting conditions. Extra luminaires (floor lamp/table lamp) will be employed without significantly improving the light exposure during the day. It is hypothesized that the introduction of enhanced lighting during the day in the living area of the intervention group will result in improved sleep quality and enhanced mental well-being.
