People with Alzheimer’s disease and related dementias may experience sleep problems, wandering, and associated daytime irritability. This study tested whether a tailored daytime lighting intervention could improve sleep and behavior in Alzheimer’s patients living in long-term care facilities.

The study involved 43 subjects diagnosed with Alzheimer’s disease and related dementias who were exposed to an active and inactive tailored lighting intervention for successive 4-week periods. Compared to baseline and to the inactive lighting condition, the lighting intervention significantly decreased sleep disturbances, depression and agitation. While all measures improved, the most significant improvement was seen in sleep quality.
