Lighting Intervention for Care Facilities

Light therapy has shown great promise as a nonpharmacological method to improve symptoms associated with Alzheimer’s disease and related dementias (ADRD), with preliminary studies demonstrating that appropriately timed light exposure can improve nighttime sleep efficiency, reduce nocturnal wandering, and alleviate evening agitation. This study investigated the effectiveness of a tailored lighting intervention for individuals with ADRD living in nursing homes.
