[Montessori Method applied to dementia, a person-centered global approach Part 2. Review of literature, effects and perspectives].

During the last ten years, the Montessori method has become a popular approach for the care of older adults living with dementia, with a growing number of institutions claiming its use. In this context, this narrative review aims at summarizing the research on its effects, benefits, and potential limits. Since the end of the 90s, a growing number of researchers across the world have investigated the Montessori method applied to dementia. Most of those studied the effects of Montessori activities. A few putted their focus on Montessori as a global, person-centered model of care. In general, research shows significant positive effects of Montessori on engagement, behaviors, affects, and functional abilities, as, for example, eating abilities. Benefits for caregivers have also been demonstrated. However, an important part of this research suffers from methodological weaknesses. In the future, other research is necessary to better understand the effects and best application conditions of Montessori method, especially in French speaking countries. Qualitative studies also seem to be a promising path to better understand where this new model of care can best lead those who apply it.
