Yes / Future populations of older adults in the UK, those aged 65+, will demonstrate increased diversity in terms of their ethnic identity resultant from the ageing of the post-war migrants from India, Pakistan, Bangladesh, and the Caribbean. As a consequence, there will be an increase in the numbers of older adults from these communities living with age-related chronic diseases such as dementia. In response to these demographic changes, we need to develop a research, policy and practice agenda that is inclusive and provides evidence for the development of culturally diverse and effective models of service delivery. This requires engagement with three key stakeholder groups: (a) people with dementia; (b) their carers; and (c) the wider community. As part of the IDEAL research programme on living well with dementia, we undertook semi-structured interviews with twelve community leaders, defined as known and trusted individuals active in their respective communities, and six community members (two people living with dementia and four carers). We explored their understandings, experiences, and views of about dementia. Our analysis identified two overarching themes. The migrant lifecourse highlighted issues of not belonging, discrimination and racism. This framed our second theme, the cultural context of dementia, which addressed dementia knowledge and attitudes, service provision and service access, and how being part of a minority ethnic community made a difference to these experiences. Our study highlights how lifecourse experiences of negative hostile social and policy environments and services can be profound and long-lasting and provide a prism through which accessing dementia care is experienced. Our findings argue for the inclusion of diverse views and lifecourse experiences within the context of developing a dementia strategy for research, policy and practice that is appropriate for a multicultural and heterogenous society. / This work was supported by the Economic and Social Research Council, National Institute for Health and Care Research (ES/L001853/2), and Alzheimer’s Society (348, AS-PR2-16-001).
