Improvement of Sleep Disorders in Patients With Alzheimer's Disease After Sunlight Exposure Therapy.

An Analysis of the Improvement of Sleep Disorders in Patients With Alzheimer's Disease After Sunlight Exposure Therapy.

This observational study aimed to understand the effect of intervention A on sleep disorders in individuals with Alzheimer's disease receiving sunlight therapy. The primary question of the study was:

Does sunlight therapy improve sleep disorders in Alzheimer's disease? Participants will complete a questionnaire, undergo sunlight therapy. They were informed that sun exposure therapy could effectively improve sleep, and behavioral interventions were discussed to develop a health education plan. Patients received monthly telephone support and encouragement from the time of admission until the next follow-up visit. Three months after admission (until the next follow-up visit), patients completed questionnaires including the Pittsburgh Sleep Quality Index (PSQI), the Neuropsychiatric Inventory (NPI), and the Quality of Life-Alzheimer's Disease (QOL-AD) questionnaire.

5. A cohabiting family member is required as the primary caregiver, who understands and cooperates with this intervention and has signed a consent form.
6. If the patient is already taking sleeping pills, the maintenance dose will not be adjusted.

Exclusion Criteria:

1. Individuals with other brain injury conditions, such as cerebral palsy, brain tumors, traumatic brain injury, or stroke.
2. Individuals with visual impairments (assessed by comparing numbers with fingers at a distance of 30 cm upon admission).
