Dementia in UK South Asians: a scoping review of the literature

"You just can't do that in dementia care": Barriers to partnership working within dementia services for people from south Asian communities

Background: People from South Asian communities are under-represented at all levels of dementia services. Consequently, there is pressure for the statutory sector to deliver services in partnership with Voluntary, Community, Faith and Social Enterprises (VCFSEs). This study set out to explore the constraints to effective partnership working which prevent dementia care from being delivered in an equitable way.Methods: Data collection consisted of two phases. First, we interviewed seven people with experience of partnership working and developed three fictional vignettes that were representative of the challenges they faced. We then used these vignettes to stimulate discussion in focus groups and interviews with 13 VCFSE and 16 statutory sector participants. Data was analysed using deductive thematic analysis.Findings: Three themes were developed during the analysis. First, White British-centric services focused on the challenges for statutory services in meeting the needs of South Asians, developing flexible, responsive services and making inclusive partnership working truly meaningful. Second, VCFSE participants (but not statutory service participants) associated a failure to deliver effective partnership working with unconscious bias operating within systems, leading to the devaluing of their expertise and to their views being ignored. Finally, participants emphasised the need to prioritise relationships if they were to meet the challenges of developing partnership working.Conclusion: We identified three constraints acting to prevent effective partnership working. First, the different meanings that statutory and VCFSE participants attach to challenges threatens their ability to develop a shared understanding of the needs of communities. Second, a reluctance to explicitly address service deficiencies can mean that stereotypes remain unaddressed. Finally, while both parties lacked power to change the fundamentals of service delivery, power and resources were also unbalanced with VCSFE services being more reliant on the statutory sector.

Understanding dementia in minority ethnic communities: The perspectives of key stakeholders interviewed as part of the IDEAL programme

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.

Understanding engagement in diet and dementia prevention research among British South Asians: a short report of findings from a patient and public involvement group

BACKGROUND

Dementia is a global public health challenge. Evidence suggests that individuals from South Asian communities are an at-risk group for dementia, partly as a result of early and cumulative exposure to known dementia risk factors, such as obesity and type 2 diabetes. There needs to be more culturally appropriate community engagement to increase awareness of dementia and identify better strategies to encourage participation in dementia-related research.

METHODS

We aimed to better understand the barriers and facilitators towards engaging with, and participating in, diet and dementia related research among British South Asians. This was achieved using a public and patient involvement (PPI) approach. A community-based, engagement event involving information sharing from experts and roundtable discussions with South Asian communities (n = 26 contributors) was held in June 2023 in Newcastle-upon-Tyne, UK. Collaboration from preidentified PPI representatives (n = 3) informed the content and structure of PPI activities, as well as recruitment. Data were synthesised using template analysis, a form of codebook thematic analysis. This involved deductively analysing data using relevant a priori themes, which were expanded upon, or modified, via inductive analysis.

RESULTS

The findings highlighted the importance of trust, representation and appreciation of cultural barriers as facilitators to engagement in diet and dementia risk reduction research. Consideration of language barriers, time constraints, social influences and how to embed community outreach activities were reported as driving factors to maximise participation.

CONCLUSIONS

This PPI work will inform the design and co-creation of a culturally adapted dietary intervention for brain health in accordance with the Medical Research Council and National Institute for Health and Care Research guidance for developing complex interventions.

A scoping review of neuropsychological assessment for Asian Indians in the United States - research and clinical recommendations

Objective: There is an increasing focus on understanding health disparities among various cultural groups in the United States. The need for heterogeneity in norms and test stimuli across ethnically diverse individuals are being increasingly recognized. However, to date it remains unknown whether and to what extent differences in cognitive norms and tests exist in Asian Indians, a fast-growing population in the U.S. It is essential to understand these differences to improve diagnostic accuracy and provide timely and appropriate clinical care. Method: In this study, we conducted a scoping review of available cognitive tests that were normed, developed, or adapted for Asian Indians living in the U.S. Results: The results suggested a paucity of norms and tests specifically examining cognition in this community. Conclusions: Based on the findings, we provide suggestions for research directions focusing on the development of culturally sensitive neuropsychological tools, normative data representative of this demographic, and interventions addressing healthcare access barriers. Overall, this review provides readers with relevant clinical information to immediately enhance patient care as well as provide actionable items in research to improve the future utility of neuropsychology for Asian Indians in the United States.

Religious Influences on the Experience of Family Carers of People with Dementia in a British Pakistani Muslim Community

This paper reports on a study that begins to address the paucity of research around the religious motivations of Muslim carers of family members with dementia. Seven carers were recruited for interviews from the British Pakistani Muslim community concentrated in the Midlands and North of England. Interview transcripts were analysed thematically using an iterative collaborative methodology. The findings suggested that the Muslim faith plays a pivotal role as a support mechanism for individual carers and their families, but the wider faith community and its leaders did not typically offer support and could impede access to external care. This was a result of cultural pressure and lack of awareness both among religious leaders and the community as a whole. The study concluded that the inequality in access to dementia services may be constructively addressed if service providers engage with these faith concerns in the community and religious leaders to meet the needs of Muslims of British Pakistani origin.

Depression, Disability, and Cognitive Impairment Among Elders With Medical Illnesses Attending Follow-Up Clinics at a Tertiary Care Hospital in Northern Sri Lanka

INTRODUCTION

The rising proportion of the elderly is increasingly affected by non-communicable diseases. Despite an abundance of literature suggesting that elders with medical conditions are more vulnerable to depression, disability, and cognitive impairment, these tend to go unnoticed and unaddressed. This study describes the prevalence and correlates of depression, disability, and cognitive impairment among elders with medical illnesses attending follow-up clinics in a tertiary care hospital in northern Sri Lanka.

METHODS

This descriptive cross-sectional study was carried out among 122 elders (≥60 years) attending medical clinics at Teaching Hospital Jaffna. Depression, disability, and cognitive impairment were assessed by the 15-item Geriatric Depression Scale, 12-item World Health Organization Disability Assessment Schedule 2.0, and Montreal Cognitive Assessment, respectively. Student's T-Test, ANOVA, and correlation coefficient were used in analyzing data using Statistical Package for Social Sciences 25 (SPSS-v25) (IBM, New York, United States).

RESULTS

The mean age of the participants was 68.3 years (SD=5.70); 58 (47.5%) were males and 64 (52.5%) were females. Prevalence of depression was 44.3% (95% CI=35.5-53.1), while disability was 95.9% (95% CI=92.4-99.4) and cognitive impairment was 80.3% (95% CI=73.2-87.4). Depression was significantly associated with gender (p=0.013), marital status (p=0.019), and living arrangement (p<0.001). Cognitive impairment was significantly associated with education level (p=0.045), and disability was associated with education level (p=0.008) and marital status (p=0.027). Among the study participants, only 12 (9.8%) had previously sought professional help for depression, disability, or cognitive impairment.

CONCLUSION

Depression, disability, and cognitive impairment are common among the elderly attending medical clinics in Teaching Hospital Jaffna, and are, in most cases, unaddressed.

Facilitators and barriers for families caring for adults living with Alzheimer's dementia: A qualitative study

This study investigates the barriers and promoters of caring for older adults living with Alzheimer's Dementia (AD) in families. This was a qualitative study through content analysis (based on the Granheim and Lundman method), and the participants were selected using purposive sampling from the families of older adults living with AD who were receiving care in the community. We used semi-structured interviews to collect data from 32 family members. The validity and reliability of the data were assessed using the Lincoln and Guba criteria. In this study, 70.58% of primary caregivers were women. Caregiving facilitators included "Efficient family," "Capable caregiver," and "Motivated caregiver." Caregiving barriers included "Lacking awareness and knowledge," "Vulnerable family," "Older person with complex/multiple needs," and "Lack of care infrastructures." Training families and caregivers and developing care infrastructures for older adults with AD can help reduce caring barriers in older adults.

Help-Seeking Behaviors Among Older Adults: A Scoping Review

Although older adults may experience health challenges requiring increased care, they often do not ask for help. This scoping review explores the factors associated with the help-seeking behaviors of older adults, and briefly discusses how minority ethnic populations can face additional challenges in help-seeking, due to factors such as language barriers and differing health beliefs. Guided by Arksey and O’Malley’s scoping review framework and the Preferred Reporting Items for Systematic Reviews and Meta-AnalysesScoping Review guidelines, a systematic search of five databases was conducted. Using a qualitative meta-synthesis framework, emergent themes were identified. Data from 52 studies meeting inclusion criteria were organized into five themes: formal and informal supports, independence, symptom appraisal, accessibility and awareness, and language, alternative medicine and residency. Identifying how factors, including independence and symptom appraisal, relate to older adults’ help-seeking behaviors may provide insights into how this population can be supported to seek help more effectively.

Cognitive Assessment in Culturally, Linguistically, and Educationally Diverse Older Populations in Europe

Due to increasing cultural, linguistic, and educational diversity in older populations across Europe, accurate assessment of cognitive functioning in people from diverse backgrounds becomes increasingly important. This paper aims to provide a state-of-the-art review of cognitive assessment in culturally, linguistically, and educationally diverse older populations in Europe, focusing on challenges and recent advances in cross-cultural assessment. Significant work has been carried out on the identification of challenges in cognitive assessment in culturally, linguistically, and educationally diverse older populations and on development and validation of cross-cultural cognitive tests. Most research has addressed the influences of language barriers, education and literacy, and culture and acculturation and in particular, the European Cross-Cultural Neuropsychological Test Battery (CNTB) and the Rowland Universal Dementia Assessment Scale (RUDAS) are well-validated across European countries. However, cross-cultural cognitive assessment is largely still a developing field in Europe, and there is a continuing need for developments within the field.

The challenges of achieving timely diagnosis and culturally appropriate care of people with dementia from minority ethnic groups in Europe

In a just society, everyone should have equal access to healthcare in terms of prevention, assessment, diagnosis, treatment and care. Europe is a multicultural society made up of people who identify with a wide range of ethnic groups. Many older people from minority ethnic groups also have a direct migration background. Several studies have shown that there is a lack of equity in relation to dementia diagnoses and care because equal opportunities do not necessarily translate into equal outcomes. An expert ethics working group led by Alzheimer Europe has produced an extensive report on this issue, a policy brief and a guide for health and social care workers. In this brief summary, the authors/members of the expert working group present some of the key challenges and recommendations for healthcare clinicians striving to provide timely diagnosis and good quality care and treatment to people with dementia from all ethnic groups.

Understanding dementia in South Asian populations, an exploration of knowledge and awareness

Given the higher prevalence of risk factors for dementia within the South Asian population, the lived experiences of people with dementia from this group are of interest. This article evaluates and summarises a qualitative synethesis of culturally specific barriers and facilitators to formal dementia care.

Cross-cultural neuropsychological assessment in the European Union: a Delphi expert study

OBJECTIVE

The increasing ethnic diversity in the European Union (EU) calls for adaptations to neuropsychological assessment practices. The aims of this study were to examine the current state of cross-cultural neuropsychological assessment in EU-15 countries and to provide recommendations for researchers and policy makers.

METHOD

Twelve experts from nine EU-15 countries participated in a Delphi consensus study involving two sequential rounds of web-based questionnaires and an in-person consensus meeting. The experts individually rated Delphi topics on the basis of importance (scale 1-10). The degree of consensus was determined by assessing first and third quartiles (Q1 and Q3) and medians.

RESULTS

Consensus outcomes showed the following priorities: (a) the development of tests (median importance rating 10, Q1-Q3: 9-10), (b) the collection of normative data (median importance rating 9, Q1-Q3: 8-10), and (c) more training, awareness, and knowledge regarding cross-cultural assessment among neuropsychologists in the EU (median importance rating 9, Q1-Q3: 8-10). Whereas memory tests were often available, tests measuring social cognition (median 9, Q1-Q3: 8-10) and language (median 9, Q1-Q3: 7-10) are particularly lacking. Recommendations were made regarding essential skills and knowledge necessary for cross-cultural neuropsychological assessment.

CONCLUSIONS

This study in a small group of experts suggests that the development and availability of cross-cultural tests and normative data should be prioritized, as well as the development and implementation of training initiatives. Furthermore, EU guidelines could be established for working with interpreters during neuropsychological assessment. Before implementing these recommendations, follow-up studies are recommended that include more minority neuropsychologists and community stakeholders.

Challenges in the diagnosis of dementia: insights from the United Kingdom-Brazil Dementia Workshop

In July 2019, a group of multidisciplinary dementia researchers from Brazil and the United Kingdom (UK) met in the city of Belo Horizonte, Minas Gerais, Brazil, to discuss and propose solutions to current challenges faced in the diagnosis, public perception and care of dementia. Here we summarize the outcomes from the workshop addressing challenges in diagnosis. Brazil faces a major problem in dementia underdiagnosis, particularly involving the population in an adverse socioeconomic context. There is poor availability of resources and specialists, and the knowledge of general practitioners and other healthcare professionals is far from satisfactory. Low education level is a further obstacle in diagnosing dementia, as the most commonly used screening tests are not designed to evaluate this population. Patients and their families must overcome the stigma of a diagnosis of dementia, which is still prevalent in Brazil and increases the burden of this condition. Whilst the UK has greater resources, dedicated memory services and a National Dementia Strategy plan, the National Health Service (NHS) has limited funding. Therefore, some challenges regarding diagnosis are common across both countries. The authors suggest possible solutions to confront these, with the goal of improving assessment and recognition of dementia and reducing misdiagnosis.

"In the Bengali Vocabulary, There Is No Such Word as Care Home": Caring Experiences of UK Bangladeshi and Indian Family Carers of People Living With Dementia at Home

BACKGROUND AND OBJECTIVES

We aimed to explore experiences of South Asian carers of people with dementia receiving health or social care in the United Kingdom, purposively recruited to encompass a range of migration, economic and cultural experiences. While previous work in this area has reported carers' understanding of, and attitudes to dementia, we explored how carers' cultural identities and values influenced their experiences, negotiation of the caring role and relationship with services.

RESEARCH DESIGN AND METHODS

We conducted semi-structured interviews with 10 Bangladeshi and Indian family carers of people living with dementia at home. We recruited participants from community settings in London and Bradford, UK. Interviews were audio recorded, transcribed and thematically analyzed.

RESULTS

We identified 4 themes: an expectation and duty to care, expectation and duty as a barrier to accessing formal care (family carer reluctance, care recipient reluctance, and service organization), culturally (in)sensitive care, and the importance of support from informal care networks.

DISCUSSION AND IMPLICATIONS

Interviewees described tensions between generations with different understandings of familial care obligations. Expectations to manage led to burden and guilt, and the cost of caring, in terms of lost employment and relationships was striking. Unlike in previous studies, interviewees wanted to engage and be supported by services, but were frequently offered care models they could not accept. There was a tension between a state-provided care system obliged to provide care when there are no alternatives, and family carers who feel a duty to always provide alternatives. Informal social networks often provided valued support.

Dementia awareness, beliefs and barriers among family caregivers in Pakistan

OBJECTIVES

Dementia research and services in Pakistan are limited. The following was explored in experiences of family caregivers of people with dementia in Pakistan: (a) to determine whether culture and religion play a role in caregiving; (b) to draw insights on how family caregivers cope, what barriers they face and what help they would be willing to accept and (c) to determine how these findings could be used to raise awareness and influence public policies in improving the lives of families living with dementia.

METHODS

The experiences of family caregivers of people with dementia in Pakistan were explored via semi-structured interviews (10 in Lahore; 10 in Karachi). This was part of a larger qualitative study conducted about dementia in Pakistan. Caregivers interviewed were aged 35-80 (14 female). Most caregivers in the study were educated and affluent. Interviews were conducted in Urdu, translated into English and thematically analysed.

RESULTS

Five themes emerged: knowledge and awareness; stigma; importance of religion and duty to care; use of day care centres and home-help; and barriers. A lack of dementia awareness exists in Pakistan. The religious duty to care for family influenced caregiving decisions. Day care centres and home-help were accessed and viewed positively. The caregivers also wanted extracurricular activities for people with dementia, support groups for caregivers and better training for healthcare staff. Novel findings included that caregivers felt that dementia should not be stigmatised, and awareness should be raised in Pakistan via TV, radio and social media, but not inside mosques.

DISCUSSION

Additional research is necessary to determine if positive views of day care centres and home-help exist more widely. Attitudes and experiences regarding stigma may be different for caregivers of people with more advanced dementia. We recommend raising dementia awareness, allocating more funds to dementia services and an emphasis on home-based care.

Recruitment and methodological issues in conducting dementia research in British ethnic minorities: A qualitative systematic review

OBJECTIVE

Identifying existing recruitment and methodological issues within dementia research conducted in UK studies that included ethnic minorities.

METHODS

We searched for and included any publication detailing dementia research in the UK that included any ethnic minority. The search results and all titles and abstracts were screened according to the inclusion criteria followed by screening of the full texts. We extracted data regarding the recruitment and methodological issues faced by the researchers. This data was combined and listed, and related issues were grouped into overarching themes and subthemes.

RESULTS

Of 52 publications suitable for analysis, 33 provided data collated into six themes: attitudes and beliefs about dementia in ethnic minority communities, recruitment process, data collection issues, practical issues, researcher characteristics, and lack of published research and normative data. These themes allowed us to identify three areas responsible for addressing these recruitment and methodological issues: community and patient education, health services, and researchers' training.

CONCLUSIONS

This is the first review identifying recruitment and methodological issues within UK dementia research that included ethnic minorities. We now have a compilation of reported existing issues and a framework of areas responsible for addressing them and devising solutions.

Ethnicity and risk of diagnosed dementia after stroke: a cohort study using the Clinical Practice Research Datalink

INTRODUCTION

The UK has over 1.2 million stroke survivors. Stroke is a major risk factor for dementia, and along with other risk factors such as hypertension and diabetes, is more common among Black, Asian and other ethnic minorities (BAME). We aimed to explore whether diagnosed dementia differed by ethnicity among adult stroke survivors.

METHODOLOGY

Using the UK Clinical Practice Research Datalink and linked hospital data, we conducted a cohort study among patients aged ≥40 years who had an incident stroke between 2005 and 2016. We fitted multivariable Cox proportional hazard models to estimate ethnic differences in the risk of poststroke dementia, adjusting for major clinical and social confounders.

RESULTS

Our cohort comprised 45 474 stroke survivors (mean age 72.6 years, 49% female), of whom 95.7% were White, 2.0% South Asian, 1.2% Black and 1.1% of Mixed/Other ethnicity. Of these, 4624 (10.2%) were diagnosed with poststroke dementia over a median follow-up of 3.26 years. Compared with the White ethnic group, those of Black ethnicity were 42% more likely to be diagnosed with dementia (adjusted HR 1.42, 95% CI 1.05 to 1.93). There was no association between any other ethnic group and poststroke dementia diagnosis.

DISCUSSION

There was good evidence that those of Black ethnicity had higher risk of diagnosed dementia poststroke. Further understanding of the mechanisms of this relationship could help target interventions at communities most at risk of dementia poststroke.
