As the Alzheimer's disease progresses, caregivers and family members often focus on behavioral difficulties. In response to crises, immediate actions tend to favor restraints, either through medication or physical means. This work aims to improve the management of behavioral disturbances in patients with Alzheimer's disease through musical interventions (group or individual), particularly in advanced stages of the disease, where medical and family resources are insufficient. The investigators approach prioritizes NTM over medication as a mean to improve patient well-being. To this end, they have designed a study. The study focuses on creating a conducive environment for sleep by incorporating ritualized, familiar music sessions supervised by nursing staff after meals. To conduct this study, the actigraphy will be used to analyze participants' behavior both day and night, complemented by questionnaires and clinical observations.
