Background: Increasing life expectancy worldwide means more people will develop dementia. Despite the rapid growth in older Bangladeshi immigrants living in the UK, there is little evidence of how community members understand and view the process of ageing and dementia. However, Bangladeshis have a higher risk of developing type 2 diabetes and heart disease, both of which are important indicators of dementia development in old age. This study aimed to explore and analyse the perception and knowledge of, and attitudes towards, ageing and dementia among the Bangladeshi community. Methods: A qualitative research approach guided two separate focus group discussions held with Bangladeshi adults in Portsmouth, UK. A topic guide was used alongside two vignettes depicting either early-or latestage dementia to stimulate discussion. The data were recorded, transcribed, and analysed thematically using NVivo qualitative software. Results: Three main themes emerged: (1) knowledge and perceptions of dementia; (2) perceived causes of dementia; and (3) perceptions of stigma about dementia. Lack of knowledge and understanding of dementia was evident, but the stigma about dementia was non-existent. This study fills a research gap by providing qualitative research examining knowledge about and attitudes towards dementia among a Bangladeshi community in England. Conclusion: Future research must highlight the importance of raising dementia awareness among, and providing information about dementia caregiving to, Bangladeshi community members, as well as providing religiously sensitive healthcare services.of dementia among Bangladeshi community members, has been highlighted. The results will provide insight for service providers, policy makers, and researchers into how dementia is perceived in the Bangladeshi community and why it has remained unreported and labelled within the broader BAME communities. It is also hoped that this study has explored the concept of dementia in depth and examined the impact of stigma on individuals, caregivers, and communities.
