Hypothesis
The study examines the impact of daytime light exposure on affect and neurobehavioral symptoms in nursing home residents with dementia.
Conclusion
Higher levels of light exposure are associated with improved emotional well-being and reduced neurobehavioral symptoms in nursing home residents with dementia.
Supporting Evidence
- Higher lux levels were significantly correlated with more contentment and less sadness, depression, and anxiety.
- Higher CCT levels were significantly correlated with less delusion and appetite changes.
- Higher CS levels were significantly correlated with decreased aberrant motor behavior and anxiety.
- CS significantly predicted decreased aberrant motor behavior, nighttime behavior, and anxiety.
Takeaway
More light can make people in nursing homes with dementia feel happier and less anxious.
Methodology
Participants wore light sensors to measure light exposure and were assessed for affect and neurobehavioral symptoms every other week.
Participant Demographics
Average age of participants was 87, with 74% being female.
