To summarize the available evidence on the effects of multisensory environments (MSE) for improving occupational engagement for people with dementia living in long-term care facilities. Seven databases were searched. The methodological quality of each study was assessed for the risk of bias. Ten studies were included in the review. Nine studies used MSE in a dedicated space, such as Snoezelen room and one used a natural MSE. Only one study used MSE as part of a task-oriented treatment plan. The included studies showed the benefits of MSE on some outcomes of occupational engagement, such as decreased agitation, improved mood and behavior, and increased environmental and social interaction. Other outcomes of interest were cognition, quality of life, balance, and ADL engagement. MSE may be used to decrease behavioral and psychological symptoms and improve mood, which may increase occupational engagement in residents of long-term care facilities who have dementia.
