People with dementia from culturally and linguistically diverse backgrounds often face poor health and social outcomes such as stigma, depression, and reduced help seeking behaviours. Dementia friendly communities have been shown to reduce stigma, and the gap in health and social outcomes for people impacted by dementia. Despite the large presence of established dementia friendly communities, their functioning in multicultural communities remains underexplored. The aim of this review was to identify the barriers and facilitators of cultural inclusivity to inform the development of a multicultural dementia friendly community. We systematically searched for academic and grey literature regarding existing and prospective age or dementia-friendly communities that engaged with culturally and linguistically diverse communities. Using the matrix method, data on the barriers and facilitators to engagement were extracted. Papers were analysed for common themes and findings were integrated in a narrative format. A total of 3,164 papers were identified, 11 of which met inclusion criteria. There were 6 dementia friendly communities in North America, 3 in Europe, 1 in Australia and 1 in Asia. Analyses revealed that barriers to cultural inclusivity were centered around the accessibility of services, sociocultural factors, and the environment, including issues such as low awareness of dementia and stigma, language barriers, isolation, and the inaccessibility of transport and buildings. Leveraging existing cultural leaders and social structures to target culturally and linguistically diverse populations and develop tailored dementia friendly initiatives were key facilitators. To foster cultural inclusivity in dementia friendly communities, a culturally specific lens that addresses these barriers and utilises facilitators must be applied from the design stage through to implementation and evaluation.
