Patients with dementia often display related sleep disturbance, depression, and behavioral and psychological symptoms, which are traditionally managed through the use of antipsychotic medications or physical restraint. However, these management interventions can have negative effects on the physical and psychological health of patients. The results of several meta-analyses suggest non-pharmacological interventions, including light therapy, should be used for the first-line management of these dementia symptoms. Light therapy uses artificial light to compensate for insufficient light exposure during the daytime and to help patients with dementia properly regulate their circadian rhythms. Sleep disturbance and depression in those with dementia may be effectively relieved through the application of light therapy. Nurses should assess the needs and symptoms of patients with dementia and consider applying light therapy as a complementary care intervention to improve quality of care.
