PREVALENCE OF SLEEP DISTURBANCES IN ALZHEIMER'S PATIENTS
Main Article Content
Abstract
Background/Aims: Sleep disturbances are a common symptom in Alzheimer's patients, affecting the quality of life of both the patients and their caregivers. The aim of this study was to describe the prevalence of sleep disturbances in patients with Alzheimer's disease. Methods: This was a cross-sectional descriptive study conducted on 137 Alzheimer's patients treated at Bach Mai Hospital and the National Geriatric Hospital Vietnam. Results: The majority of patients in the study had sleep disturbances (69,3%). Sleep disturbances occurring after the onset of Alzheimer's symptoms were the most prevalent (47,4%). The common types of sleep disturbances in Alzheimer's patients in the study were circadian rhythm sleep-wake disorders (51,1%), insomnia disorder (47,4%), and obstructive sleep apnea (36,5%). Restless legs syndrome had a small prevalence rate (6,6%). Conclusion: Sleep disturbances are a frequent symptom in Alzheimer's patients. The common types of sleep disturbances in Alzheimer's patients are circadian rhythm sleep-wake disorders, insomnia, and obstructive sleep apnea, while restless legs syndrome is less common.
