With the aging of the population, Alzheimer's disease and associated disorders represent a major public health challenge. To date there is no pharmacological treatment to stop the degenerative process or behavioral disorders. This explains the importance of non-pharmacological approaches to stimulate cognition, reduce behavioral disorders or improve quality of life. Non-pharmacological therapies are the central focus of care, especially for patients accommodated on a part-time basis (Day Hospital, Respite Platform) or Full-Time nursing home (EHPAD in French). TNM also holds an important place for patients living at home, and belongs to the very general framework of informal care, which is a significant cost.
