This paper explores the relationship between sleep disturbances and cognitive decline in Alzheimer's disease. Sleep disruptions have been identified as a common symptom of Alzheimer's, affecting up to 50–70% of patients. As such, due to the high rates of Alzheimer's disease in our aging population, there is an increased need to identify this relationship and potential interventions. This paper adopted an integrative review approach to achieve this goal. Findings show a strong link between sleep disturbances and Alzheimer's disease. Sleep problems were found to decrease patients' general prognosis and hasten the development of Alzheimer's disease due to rapid cognitive decline. Studies show various sleep-related problems in patients with Alzheimer's, including changes in sleep architecture, decreased sleep efficiency, increased sleep fragmentation, and disturbances in circadian rhythm. In addition, results show that sleep disturbances in Alzheimer's disease are multifactorial and include behavioral and physiological factors. The paper highlights the importance of sleep hygiene and non-pharmacological interventions for managing sleep disturbances in Alzheimer's patients. The paper also identifies the need for more research in the field, particularly in investigating the relationship between sleep disturbances and behavioral and psychological symptoms of dementia in Alzheimer's disease patients.
