Little is known about the lived experience of dementia in the New Zealand Chinese community. This study aims to explore the understanding and experiences of living with dementia in Chinese New Zealanders. Participants were recruited from a memory service and a community dementia day programme. In-depth interviews were conducted by bilingual and bicultural researchers. The recorded interviews were transcribed and thematically analysed. Sixteen people living with dementia and family carers participated in this study. The first theme revealed the lack of understanding of dementia prior to diagnosis, the commonly used term of “brain shrinkage” and that dementia is associated with getting older. The second theme covered the symptoms experienced by people with dementia and how family carers found anhedonia and apathy particularly concerning. The third theme highlighted the tension between cultural obligation and carer stress. The fourth theme is about the stigma attached to dementia. Our results provide some insight into ways to improve dementia care for Chinese New Zealanders, including targeted psychoeducation in the Chinese community to improve awareness and to reduce stigma, access to person-centred interventions, and learning about strategies for healthy ageing to live well with dementia, and emotional support and psychoeducation for family carers to reduce carer stress.

Background: Observational studies have demonstrated that a higher resting heart rate (RHR) is associated with an increased risk of dementia. However, it is not clear whether the association is causal. This study aimed to determine the causal effects of higher genetically predicted RHR on the risk of dementia. Methods: We performed a two-sample Mendelian randomization analysis to investigate the causal effect of higher genetically predicted RHR on Alzheimer’s disease (AD) using summary statistics from genome-wide association studies. The generalized summary Mendelian randomization (GSMR) analysis was used to analyze the corresponding effects of RHR on following different outcomes: 1) diagnosis of AD (International Genomics of Alzheimer’s Project), 2) family history (maternal and paternal) of AD from UK Biobank, 3) combined meta-analysis including these three GWAS results. Further analyses were conducted to determine the possibility of reverse causal association by adjusting for RHR modifying medication. Results: The results of GSMR showed no significant causal effect of higher genetically predicted RHR on the risk of AD (β_GSMR = 0.12, P = 0.30). GSMR applied to the maternal family history of AD (β_GSMR = −0.18, P = 0.13) and to the paternal family history of AD (β_GSMR = −0.14, P = 0.39) showed the same results. Furthermore, the results were robust after adjusting for RHR modifying drugs (β_GSMR = −0.03, P = 0.72). Conclusion: Our study did not find any evidence that supports a causal effect of RHR on dementia. Previous observational associations between RHR and dementia are likely attributed to the correlation between RHR and other cardiovascular diseases.
