Dementia among Minority Populations: A Scoping Review of Meaning, Language, and Translation

BACKGROUND

Dementia as a neurocognitive disorder is becoming increasingly common worldwide, and minority groups are more vulnerable than the general population. Many factors may contribute to their vulnerability such as misconceptions, language barriers, cultural factors, invalid assessment tools, lack of knowledge, or assigning spiritual beliefs to dementia symptoms. Therefore, this scoping literature review aimed to clarify how empirical studies reflect the meaning of dementia, language, and translation among minority ethnic groups.

SUMMARY

The PRISMA extension for the scoping review protocol was used. Thirty-eight studies published in English were reviewed and analysed. The findings revealed that lack of knowledge about dementia and attributing the disease to the normal ageing process were frequent among minority groups. Furthermore, their cultural-specific perspectives and worldviews of wellness and well-being can impact the way dementia is perceived, consequent help-seeking behaviours, or caregiving. Facilitating educational programs to enhance the knowledge and experiences of ethnic communities might be beneficial. Moreover, language is shown to be an important aspect in dementia assessment and participants' educational level could significantly impact their functional capacity when responding to cognitive measures. Even though there are some useful screening tests, diagnosis barriers might be eased by assessment tool development, modifications, and accurate translations for ethnic communities.

KEY MESSAGES

A promising pathway to support ethnically diverse communities regarding dementia can be raising awareness, providing ethnic-specific services, developing cultural-specific tools to assess dementia or any cognitive impairment by considering perceptions, language, and culture among ethnic groups. Cultural and spiritual considerations could also encourage engagement during assessment.

He Taonga Te Wareware: Connecting Older Māori Experiences of Wairuatanga with Mate Wareware (Dementia)

Mate wareware (dementia) is a complex disease of the brain that progressively inhibits memory and cognitive ability, affecting many Māori (the Indigenous people of Aotearoa New Zealand) kaumātua (elderly persons) in Aotearoa (New Zealand). Mate wareware care aims to protect and sustain wellbeing, yet Māori perspectives of wellbeing that consider wairuatanga (Māori spirituality) are often neglected within current treatment planning. This study investigates the presence of wairuatanga within kaumātua lives, drawing upon 61 interviews with kaumātua to glean a Māori understanding of mate wareware and to develop a diagnostic screening tool for mate wareware. Recorded responses were thematically analysed using reflexive qualitative analysis, informing four key themes that influence wairuatanga: he hononga tangata (social connection), tūrangawaewae (places of connection), tuakiritanga (identity) and mahi mauritau (mindful practices). These themes consider the value of creating rich and gratifying lifestyles for kaumātua that cultivate their spiritual wellbeing. This study validates diverse understandings and experiences of wairuatanga as essential to Māori wellbeing, affirming the relevance of wairuatanga to improve outcomes for Māori living with mate wareware.

Health effects of Indigenous language use and revitalization: a realist review

Background

Indigenous populations across the world are more likely to suffer from poor health outcomes when compared to other racial and ethnic groups. Although these disparities have many sources, one protective factor that has become increasingly apparent is the continued use and/or revitalization of traditional Indigenous lifeways: Indigenous language in particular. This realist review is aimed at bringing together the literature that addresses effects of language use and revitalization on mental and physical health.

Methods

Purposive bibliographic searches on Scopus were conducted to identify relevant publications, further augmented by forward citation chaining. Included publications (qualitative and quantitative) described health outcomes for groups of Indigenous people who either did or did not learn and/or use their ancestral language. The geographical area studied was restricted to the Americas, Australia or New Zealand. Publications that were not written in English, Spanish, French, Portuguese or German were excluded. A realist approach was followed to identify positive, neutral or negative effects of language use and/or acquisition on health, with both qualitative and quantitative measures considered.

Results

The bibliographic search yielded a total of 3508 possible publications of which 130 publications were included in the realist analysis. The largest proportion of the outcomes addressed in the studies (62.1%) reported positive effects. Neutral outcomes accounted for 16.6% of the reported effects. Negative effects (21.4%) were often qualified by such issues as possible cultural use of tobacco, testing educational outcomes in a student’s second language, and correlation with socioeconomic status (SES), health access, or social determinants of health; it is of note that the positive correlations with language use just as frequently occurred with these issues as the negative correlations did.

Conclusions

Language use and revitalization emerge as protective factors in the health of Indigenous populations. Benefits of language programs in tribal and other settings should be considered a cost-effective way of improving outcomes in multiple domains.

Volume, scope, and consideration of ethical issues in Indigenous cognitive impairment and dementia research: A systematic scoping review of studies published between 2000-2021

INTRODUCTION

High quality research involving Indigenous people with cognitive impairment and dementia is critical for informing evidence-based policy and practice. We examined the volume, scope and ethical considerations of research related to dementia with Indigenous populations globally from January 2000-December 2021.

METHODS

Studies were included if they were published in English from 2000 to 2021 and provided original data that focused on cognitive impairment or dementia in any Indigenous population.

RESULTS

The search yielded 13,009 papers of which, 76 met inclusion criteria. The overall number of papers increased over time. Studies were mostly conducted in Australia with Aboriginal and Torres Strait Islander people (n = 30; 39%). Twenty-six papers directly involved Indigenous participants with cognitive impairment or dementia. Of these studies, ethics approval was commonly required from two or more committees (n = 23, 88.5%). Ethical and legal governance frameworks were rarely discussed.

DISCUSSION

There is a clear need for further robust studies examining cognitive impairment and dementia with Indigenous populations. Future research should consider the ethical aspects of involving Indigenous participants with cognitive impairment in research.
