Automate Music Therapy for the Management of Behavioral Disorders in Nursing Homes (MAGE)

Alzheimer disease is the most common neurodegenerative brain disease that causes cognitive impairment in the elderly but also behavioral and psychological symptoms. Among these symptoms, agitation is one of the most dangerous because it put the patient and their caregivers in danger. Sleep disorders can be the cause of many psychiatric symptoms leading directly or indirectly to agitation. Music therapy is the non-drug therapy which has been shown to be the most effective in managing agitation and sleep disorders. With the MAGE protocol, the investigators propose to take care of behavioral disorders in severe Alzheimer patients living in nursing home through sequences of music therapy (stimulation, relaxation) automatically initiated by an actigraph that will detect sleep disorders. These subjects will be exposed for 2 weeks over a month. Behavioral and sleep disorders will be evaluated objectively by actigraphy but also by standardized scales, as the others neuropsychiatric symptoms found classically in this disease. Thanks to this project, the investigators hope to improve the quality of life of these patients by preventing them from putting themselves in danger, by reducing their neuropsychiatric symptoms and their use of medication, which has often deleterious side effect and also by reducing the workload of caregivers.
