Suchy‐Dicey AM, Domoto‐Reilly K, Nelson L, Jayadev S, Buchwald DS, Grabowski TJ, Rhoads K. Epidemiology and prevalence of dementia and Alzheimer's disease in American Indians: Data from the Strong Heart Study. Alzheimers Dement 2024; 20:4174-4184. [PMID: 38747387 PMCID: PMC11180871 DOI: 10.1002/alz.13849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2024] [Revised: 03/27/2024] [Accepted: 03/28/2024] [Indexed: 06/18/2024]
Abstract
INTRODUCTION Accurate epidemiologic estimates for dementia are lacking for American Indians, despite substantive social and health disparities. METHODS The Strong Heart Study, a population-based cohort of 11 American Indian tribes, conducted detailed cognitive testing and examinations over two visits approximately 7 years apart. An expert panel reviewed case materials for consensus adjudication of cognitive status (intact; mild cognitive impairment [MCI]; dementia; other impaired/not MCI) and probable etiology (Alzheimer's disease [AD], vascular bain injury [VBI], traumatic brain injury [TBI], other). RESULTS American Indians aged 70-95 years had 54% cognitive impairment including 10% dementia. VBI and AD were primary etiology approximately equal proportions (>40%). Apolipoprotein (APO) Eε4 carriers were more common among those with dementia (p = 0.040). Plasma pTau, glial fibrillary acidic protein (GFAP), and neurofilament light chain (NfL) were higher among those with cognitive impairment, but not amyloid beta (Aβ). Cognitive intact had mean 3MSE 92.2 (SD 6.4) and mean Montreal Cognitive Assessment (MoCA) score of 21.3 (SD 3.2). DISCUSSION This is the first population-based study to estimate the prevalence of vascular and Alzheimer's dementias in a population-based study of American Indians. HIGHLIGHTS The Strong Heart Study is a population-based cohort of American Indian tribes, conducted over 30+ years and three US geographic regions (Northern Plains, Southern Plains, Southwest). Our teams conducted detailed cognitive testing, neurological examination, and brain imaging over two visits approximately 7 years apart. An expert panel reviewed collected materials for consensus-based adjudication of cognitive status (intact; MCI; dementia; other impaired/not MCI) and probable underlying etiology (AD; VBI; TBI; other). In this cohort of American Indians aged 70-95, 54% were adjudicated with cognitive impairment, including approximately 35% MCI and 10% dementia. These data expand on prior reports from studies using electronic health records, which had suggested prevalence, and incidence of dementia in American Indians to be more comparable to the majority population or non-Hispanic White individuals, perhaps due to latent case undercounts in clinical settings. Vascular and neurodegenerative injuries were approximately equally responsible for cognitive impairment, suggesting that reduction of cardiovascular disease is needed for primary prevention. Traumatic injury was more prevalent than in other populations, and common among those in the "other/not MCI" cognitive impairment category. Mean scores for common dementia screening instruments-even among those adjudicated as unimpaired-were relatively low compared to other populations (mean unimpaired 3MSE 92.2, SD 6.4; mean unimpaired MoCA 21.3, SD 3.2), suggesting the need for cultural and environmental adaptation of common screening and evaluation instruments.

Abstract
BACKGROUND The global burden dementia is growing each year. Clinical trials investigating approaches to preventing dementia have been occurring for decades, but they are particularly challenging including the requirement to include large numbers of healthy 'at-risk' people who need to be followed up for a long period of time. Community and consumer involvement in trial design helps to ensure that the methods are acceptable to the involved stakeholders, the design and operation of clinical trials are suitable and applicable to the target population, and that key areas of concern are identified and addressed at an early stage. OBJECTIVES To gain insights from samples of memory clinic patients without dementia and general practitioners on the acceptability of, and attitudes towards, the proposed design of a decentralised antihypertensive dementia prevention trial. Topics addressed included the assessment of cognition, antihypertensive medication use, and motivation to participate in research. METHODS Two focus groups (total n = 7) with memory clinic patients and individual interviews with GPs (n = 5) were conducted. Transcripts were analysed using qualitative thematic framework analysis. RESULTS The proposed design was acceptable, with some possible barriers identified regarding computer use, GP time restraints, and concerns about medication interactions. Additional themes included the importance of communication and social connectedness in research participation and perceptions of ageing in medical settings. Future directions of research into larger studies and consumer-led research practices were discussed. CONCLUSION The proposed trial design was agreed to be acceptable with some operational considerations, which were incorporated in the trial design.

Abstract
Despite relatively higher rates of dementia among Indigenous populations internationally, research into drivers of disparities in brain health and cognitive function has tended to focus on modifiable risk factors over cultural understandings and contextual determinants. By seeking to characterize social and cultural factors that shape brain health and cognition in Indigenous populations, this mini scoping review expands prevailing schools of thought to include Indigenous knowledge systems. This reveals important gaps in culturally aligned care. It also reclaims horizons for research important to Indigenous Peoples that have garnered diminished attention in biomedical approaches. Twenty-three sources were included for data extraction. This synthesis of 23 sources includes health communication about dementia, health provider knowledge about Indigenous health, culturally relevant screening and assessment tools, and culturally grounded care models. Much of the focus is currently still on modifiable risk factors that reside at individual factors, whereas attention to wider social factors that impact populations is needed, as stressors through isolation, discrimination, and unequal care are widely reported. Going forward, identifying structural barriers to living well and recognizing the importance of connection to culture will benefit both Indigenous and non-Indigenous understandings of brain health.

Abstract
INTRODUCTION Dementia is an emergent health priority for Indigenous peoples worldwide, yet little is known about disease drivers and protective factors. METHODS Database searches were conducted in March 2022 to identify original publications on risk, protective, genetic, neuroradiological, and biological factors related to dementia and cognitive impairment involving Indigenous peoples. RESULTS Modifiable risk factors featured across multiple studies include childhood adversity, hearing loss, low education attainment, unskilled work history, stroke, head injury, epilepsy, diabetes, hypertension, hyperlipidemia, depression, low BMI, poor mobility, and continence issues. Non-modifiable risk factors included increasing age, sex, and genetic polymorphisms. Education, ex-smoking, physical and social activity, and engagement with cultural or religious practices were highlighted as potential protective factors. There is a paucity of research on dementia biomarkers involving Indigenous peoples. DISCUSSION Greater understanding of modifiable factors and biomarkers of dementia can assist in strength-based models to promote healthy ageing and cognition for Indigenous peoples.

Valuing indigenous quality of life: A review of preference-based quality of life instruments and elicitation techniques with global older indigenous populations. Soc Sci Med 2023; 336:116271.

Abstract
Indigenous perspectives of quality of life (QoL) are different to that of non-Indigenous populations. Determining how to identify and value what is important to QoL for people from diverse cultural backgrounds is crucial for assessing effective outcomes for quality assessment and health economic evaluation to guide evidence-based decision making. This is particularly important for older Indigenous people who have complex care and support needs within health and aged-care systems. This scoping review aims to assess the existing literature in this field by firstly identifying preference based instruments that have been applied with older Indigenous peoples and secondly, exploring the extent to which existing preference based instruments applied with older Indigenous peoples encompass older Indigenous peoples QoL perspectives in their design and application. The inclusion criteria for the review were studies using preference based QoL instruments with an Indigenous population where the cohort was aged 50 years or over. This resulted in the critical analysis of 12 studies. The review identified that preference based QoL instruments have rarely been applied to date with older Indigenous populations with most instruments found to be designed for non-Indigenous adults. Typically, instruments have not incorporated Indigenous worldviews of QoL into either the content of the descriptive system or the elicitation techniques and corresponding value sets generated. To encapsulate Indigenous cultural perspectives accurately in economic evaluation, further research is required as to how QoL domains in preference based instruments for Indigenous peoples can be reflective of Indigenous perspectives. It is imperative that the QoL preferences of older Indigenous peoples are adequately captured within preference based QoL instruments applied with this population.

Abstract
The aim of this review was to evaluate the relationship between periodontal disease (PD) and the onset and progression of Alzheimer's disease (AD) and to determine whether patients with PD would be at greater risk of developing AD compared to periodontally healthy subjects. This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. An electronic search for cross-sectional, cohort, or case-control studies was conducted on five databases (PubMed, ScienceDirect, EBSCO, Web of Science, and Scopus). No restrictions were applied to the language and year of publication. Exposure was PD, and the outcome of interest was the onset and/or progression of AD. The risk of bias of the included studies was assessed using the Newcastle-Ottawa Scale (NOS) designed for non-randomized studies. Six studies fulfilling the selection criteria were included in this systematic review. Four of the studies were of cohort design and two were of case-control design. All except one showed a significant association between PD and the risk of AD onset and progression. According to the NOS bias risk assessment, three studies were found to be of good quality, and three other cohort studies were of low quality. Data from this systematic review indicate that patients with PD present a significantly higher risk of AD compared to individuals with healthy periodontium. However, results should be interpreted with caution given the methodological limitations found. For future research, powerful and comparable epidemiological studies are needed to evaluate the relationship between PD and AD.

Abstract
Background Risk factors for dementia have distinct frequency and impact in relation to race. Our aim was to identify differences in modifiable risk factors of dementia related to races and estimate their population attributable fraction (PAF). Methods An epidemiological cohort was used to estimate the prevalence of 10 modifiable risk factors for dementia among five races—White, Black, Brown, Asian, and Indigenous. Sample weighting was used to estimate the prevalence and PAF of each risk factor in each race. Results A total of 9070 individuals were included. Overall adjusted PAF was the lowest in Indigenous (38.9%), and Asian individuals (41.2%). Race‐related prevalence of individual risk factors was widely variable in our population, but hearing loss was the most important contributor to the overall PAF in all races. Conclusions Public policies aiming to reduce preventable risk factors for dementia should take into consideration the race of the target populations. HIGHLIGHTS Preventable risk factors for dementia vary according to race. Hearing loss presented the highest prevalence among all races studied. Indigenous and Asian individuals presented the lowest population attributable fractions. Black and Brown individuals were more vulnerable to social determinants.

Abstract
INTRODUCTION We evaluated the prevalence of dementia and mild cognitive impairment (MCI) in indigenous Tsimane and Moseten, who lead a subsistence lifestyle. METHODS Participants from population-based samples ≥ 60 years of age (n = 623) were assessed using adapted versions of the Modified Mini-Mental State Examination, informant interview, longitudinal cognitive testing and brain computed tomography (CT) scans. RESULTS Tsimane exhibited five cases of dementia (among n = 435; crude prevalence = 1.2%, 95% confidence interval [CI]: 0.4, 2.7); Moseten exhibited one case (among n = 169; crude prevalence = 0.6%, 95% CI: 0.0, 3.2), all age ≥ 80 years. Age-standardized MCI prevalence was 7.7% (95% CI: 5.2, 10.3) in Tsimane and 9.8% (95% CI: 4.9, 14.6) in Moseten. Cognitive impairment was associated with visuospatial impairments, parkinsonian symptoms, and vascular calcification in the basal ganglia. DISCUSSION The prevalence of dementia in this cohort is among the lowest in the world. Widespread intracranial medial arterial calcifications suggest a previously unrecognized, non-Alzheimer's disease (AD) dementia phenotype.

Abstract
OBJECTIVE Estimates of dementia prevalence in New Zealand (NZ) have previously been extrapolated from limited Australasian studies, which may be neither accurate nor reflect NZ's unique population and diverse ethnic groups. This study used routinely collected health data to estimate the 1-year period prevalence for diagnosed dementia for each of the 4 years between July 2016 and June 2020 in the age 60+ and age 80+ populations and for the four main ethnic groups. DESIGN A population-based descriptive study. SETTING Seven national health data sets within the NZ Integrated Data Infrastructure (IDI) were linked. Diagnosed dementia prevalence for each year was calculated using the IDI age 60+ and age 80+ populations as the denominator and also age-sex standardised to allow comparison across ethnic groups. PARTICIPANTS Diagnosed dementia individuals in the health datasets were identified by diagnostic or medication codes used in each of the data sets with deduplication of those who appeared in more than one data set. RESULTS The crude diagnosed dementia prevalence was 3.8%-4.0% in the age 60+ population and 13.7%-14.4% in the age 80+ population across the four study years. Dementia prevalence age-sex standardised to the IDI population in the last study period of 2019-2020 was 5.4% for Māori, 6.3% for Pacific Islander, 3.7% for European and 3.4% for Asian in the age 60+ population, and 17.5% for Māori, 22.2% for Pacific Islander, 13.6% for European and 13.5% for Asian in the age 80+ population. CONCLUSIONS This study provides the best estimate to date for dementia prevalence in NZ but is limited to those people who were identified as having dementia based on data from the seven included data sets. The findings suggest that diagnosed dementia prevalence is higher in Māori and Pacific Islanders. A nationwide NZ community-based dementia prevalence study is much needed to confirm the findings of this study.

Abstract
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.

Abstract
ABSTRACT. Studies on the prevalence of dementia in the indigenous population are still scarce worldwide. In the few available studies, prevalence evidence varies from low to very high, with early onset of the disease and high mortality rate after the initial diagnosis. Still, little is known about the rate of dementia in indigenous populations from low- and middle-income countries, where the dementia prevalence in the general population is estimated to increase significantly in the next decades. Objective: This study aimed to determine the prevalence of cognitive impairment and associated factors in Brazilian indigenous people of the Mura ethnicity in Amazonas, Brazil. Methods: A total of 217 indigenous individuals aged 50 years and older from Amazonas, Brazil, were submitted to cognitive assessment. Attention, memory, verbal fluency, visuospatial performance, and mood state composed the cognitive impairment diagnosis. Results: The prevalence of cognitive impairment was 43.3% (95%CI 36.6-49.7) and varied according to age [OR=1.03 (95%CI 1.00-1.06)], education [OR=0.74 (95%CI 0.62-0.87)], body mass index [OR=0.91 (95%CI 0.83-0.98)], and income [OR=0.52 (95%CI 0.27-0.99)]. Conclusions: Cognitive impairment had an early onset in an indigenous community, and its prevalence was greater in older individuals with low education and low family income. These findings highlight the importance of implementing public indigenous health policies focusing on health professional training for early cognitive impairment detection.

Abstract
IMPORTANCE The racial and ethnic diversity of the US, including among patients receiving their care at the Veterans Health Administration (VHA), is increasing. Dementia is a significant public health challenge and may have greater incidence among older adults from underrepresented racial and ethnic minority groups. OBJECTIVE To determine dementia incidence across 5 racial and ethnic groups and by US geographical region within a large, diverse, national cohort of older veterans who received care in the largest integrated health care system in the US. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study within the VHA of a random sample (5% sample selected for each fiscal year) of 1 869 090 participants aged 55 years or older evaluated from October 1, 1999, to September 30, 2019 (the date of final follow-up). EXPOSURES Self-reported racial and ethnic data were obtained from the National Patient Care Database. US region was determined using Centers for Disease Control and Prevention (CDC) regions from residential zip codes. MAIN OUTCOMES AND MEASURES Incident diagnosis of dementia (9th and 10th editions of the International Classification of Diseases). Fine-Gray proportional hazards models were used to examine time to diagnosis, with age as the time scale and accounting for competing risk of death. RESULTS Among the 1 869 090 study participants (mean age, 69.4 [SD, 7.9] years; 42 870 women [2%]; 6865 American Indian or Alaska Native [0.4%], 9391 Asian [0.5%], 176 795 Black [9.5%], 20 663 Hispanic [1.0%], and 1 655 376 White [88.6%]), 13% received a diagnosis of dementia over a mean follow-up of 10.1 years. Age-adjusted incidence of dementia per 1000 person-years was 14.2 (95% CI, 13.3-15.1) for American Indian or Alaska Native participants, 12.4 (95% CI, 11.7-13.1) for Asian participants, 19.4 (95% CI, 19.2-19.6) for Black participants, 20.7 (95% CI, 20.1-21.3) for Hispanic participants, and 11.5 (95% CI, 11.4-11.6) for White participants. Compared with White participants, the fully adjusted hazard ratios were 1.05 (95% CI, 0.98-1.13) for American Indian or Alaska Native participants, 1.20 (95% CI, 1.13-1.28) for Asian participants, 1.54 (95% CI, 1.51-1.57) for Black participants, and 1.92 (95% CI, 1.82-2.02) for Hispanic participants. Across most US regions, age-adjusted dementia incidence rates were highest for Black and Hispanic participants, with rates similar among American Indian or Alaska Native, Asian, and White participants. CONCLUSIONS AND RELEVANCE Among older adults who received care at VHA medical centers, there were significant differences in dementia incidence based on race and ethnicity. Further research is needed to understand the mechanisms responsible for these differences.

Abstract
Objectives Dementia poses one of the greatest global health challenges, affecting 50 million people worldwide. With 10 million new cases each year, dementia is a growing burden, particularly in low- and middle-income countries (LMIC). This study aimed to identify the facilitators and barriers to providing quality dementia assessment and care in LMICs from a global health perspective. Methods/Design A qualitative semi-structured interview study with 20 dementia expert healthcare providers from 19 countries. To be included, providers had to: practice dementia assessment or care in LMICs where the population over age 60 is projected to more than double by 2050 and be recognized as a leading dementia expert in the region based on position, research publications, and/or policy leadership. Interviews were analyzed by a multidisciplinary team of researchers using thematic analysis. Results Barriers to dementia assessment and care included stigma about dementia, poor patient engagement in and access to healthcare, inadequate linguistic and cultural validation, limited dementia capable workforce, competing healthcare system priorities, and insufficient health financing. Facilitators included the rise in dementia awareness campaigns, dementia training for general practitioners, availability of family support and family caregivers, and national and international collaborations including coordinated policy efforts and involvement in international research initiatives. Conclusions Findings from this study provide insights for prioritizing dementia assessment and care capacity-building in LMICs as a global health priority and for tailored public health approaches to strengthen dementia assessment and care at the individual, community, national, and multi-national levels.

Abstract
As life expectancy increases for Indigenous populations, so does the number of older adults with complex, chronic health conditions and age-related geriatric syndromes. Many of these conditions are associated with modifiable lifestyle factors that, if addressed, may improve the health and wellbeing of Indigenous peoples as they age. If models of healthy aging are to be promoted within health services, a clearer understanding of what aging well means for Indigenous peoples is needed. Indigenous peoples hold a holistic worldview of health and aging that likely differs from Western models. The aims of this review were to: investigate the literature that exists and where the gaps are, on aging well for Indigenous peoples; assess the quality of the existing literature on Indigenous aging; identify the domains of aging well for Indigenous peoples; and identify the enablers and barriers to aging well for Indigenous peoples. A systematic search of online databases, book chapters, gray literature, and websites identified 32 eligible publications on Indigenous aging. Reflexive thematic analysis identified four major themes on aging well: (1) achieving holistic health and wellbeing; (2) maintaining connections; (3) revealing resilience, humor, and a positive attitude; and (4) facing the challenges. Findings revealed that aging well is a holistic concept enabled by spiritual, physical, and mental wellbeing and where reliance on connections to person, place, and culture is central. Participants who demonstrated aging well took personal responsibility, adapted to change, took a positive attitude to life, and showed resilience. Conversely, barriers to aging well arose from the social determinants of health such as lack of access to housing, transport, and adequate nutrition. Furthermore, the impacts of colonization such as loss of language and culture and ongoing grief and trauma all challenged the ability to age well. Knowing what aging well means for Indigenous communities can facilitate health services to provide culturally appropriate and effective care.

Abstract
AIMS To appraise the empirical literature on the needs of Indigenous informal caregivers caring for people living with dementia in Indigenous communities. DESIGN Whittemore and Knafl's updated approach to integrative reviews, PRISMA guidelines, and CASP checklists for narrative analysis were followed. DATA SOURCES A systematic search of published empirical literature from January 2010 to August 2020 was undertaken in six databases. REVIEW METHODS Fifty-one studies met the research question and the inclusion criteria. RESULTS Five themes describe the findings: Decolonizing Western perspectives on dementia, the centrality of cultural safety, caregivers' experiences, pre-dementia community education and family and community-centred care emerged from the thematic analysis. Most of the studies used quantitative methodologies, and few studies were conducted using community-based approaches. CONCLUSION This review shows that Indigenous caregiving represents an emerging field in nursing and health sciences in a context of a global crisis. Researchers need to focus on Indigenous values and voices to adapt care and support informal caregivers. Our review emphasizes that working with Indigenous communities will likely translate into new care delivery models, policies and practices to support Indigenous informal caregivers and address the specific social determinants impacting caregivers' roles and tasks. IMPACT This review highlights the necessity of having community and family-based discussions on enhancing the delivery of dementia care for Indigenous peoples in Canada and worldwide. Decolonizing Western perspectives of dementia translate into culturally safe approaches that aim to integrate Indigenous cultural perspectives of holism, reciprocity, wisdom, respect of older people and relationality into nursing practice. The support of Indigenous informal caregivers requires future studies to address the stigmatizing Western views of dementia.

Abstract
BACKGROUND AND OBJECTIVES The lack of appropriate quality of life (QoL) measures is a major barrier to planning and delivering health and aged care services for older Indigenous peoples worldwide. QoL is dependent on cultural values and priorities may vary between age groups. This project aims to develop a QoL tool for older Aboriginal Australians. RESEARCH DESIGN AND METHODS The study was completed with Aboriginal Australians aged over 45 years living in Perth and Melbourne, Australia. Participatory Action Research methods were applied with an Indigenous research paradigm. Semistructured interviews were undertaken to identify the factors important to having a good life. Factors were further explored in yarning groups with older Aboriginal peoples to develop the draft QoL tool questions. Face validity of the tool was completed in two regions. RESULTS The participants preferred the term "a good life" to QoL. Having a good spirit is at the core of having a good life. The protective factors for a good life were family and friends, health, culture, Elder role, respect, Country, spirituality, services and supports, community, future plans, safety and security, and basic needs. DISCUSSION AND IMPLICATIONS Twelve factors were identified and developed into key questions for the Good Spirit, Good Life tool. The draft tool will undergo quantitative validity testing, prior to embedding in service provision to inform care for older Aboriginal peoples. With local adaptation, the tool, accompanying framework, and participatory methods for development may have wider applicability to other Indigenous populations worldwide.

Abstract
BACKGROUND The prevalence of dementia is generally reported to be higher among Indigenous peoples. OBJECTIVE The rates and coding of dementia mortality were compared between Indigenous and non-Indigenous Australians. METHODS De-identified individual records on causes of death for all people aged 40 years or more who died in Australia between 2006 and 2014 (n = 1,233,084) were used. There were 185,237 records with International Classification of Diseases, Tenth Revision, codes for dementia (Alzheimer's Disease, vascular dementia, or unspecified dementia) as the underlying cause of death or mentioned elsewhere on the death certificate. Death rates were compared using Poisson regression. Logistic regression was used to assess whether dementia was more likely to be classified as 'unspecified' type in Indigenous Australians. RESULTS The rates of death with dementia were 57% higher in Indigenous Australians, compared to non-Indigenous, relative rate (RR) 1.57, 95% confidence interval (CI) (1.48, 1.66), p < 0.0001. This excess of deaths was highest at ages below 75 (RRs > 2, test for interaction p < 0.0001), and among men (test for interaction p < 0.0001). When the underreporting of Indigenous status on the death certificate was taken into account the relative rate increased to 2.17, 95% CI (2.07, 2.29). Indigenous Australians were also more likely to have their dementia coded as 'unspecified' on their death certificate (Odds Ratio 1.92, 95% CI (1.66, 2.21), p < 0.0001), compared to the non-Indigenous group. CONCLUSION This epidemiological analysis based on population level mortality data demonstrates the higher dementia-related mortality rate for Indigenous Australians especially at younger ages.

Abstract
INTRODUCTION Despite increasing dementia rates, few culturally informed cognitive assessment tools exist for Indigenous populations. The Canadian Indigenous Cognitive Assessment (CICA) was adapted with First Nations on Manitoulin Island, Canada, and provides a brief, multi-domain cognitive assessment in English and Anishinaabemowin. METHODS Using community-based participatory research (CBPR) methods, we assessed the CICA for inter-rater and test-retest reliability in 15 individuals. We subsequently evaluated validity and established meaningful CICA cut-off scores in 55 individuals assessed by a geriatrician. RESULTS The CICA demonstrated strong reliability (intra-class coefficient = 0.95 [0.85,0.98]). The area under the curve (AUC) was 0.98 (0.94, 1.00), and the ideal cut-point to identify likely cases of dementia was a score of less than or equal to 34 with sensitivity of 100% and specificity of 85%. DISCUSSION When used with older First Nations men and women living in First Nations communities, the CICA offers a culturally safe, reliable, and valid assessment to support dementia case-finding.

Cognitive Differences in the Older Adults Living in the General Community: Gender and Mental Occupational State Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18063106. [PMID: 33802961 PMCID: PMC8002664 DOI: 10.3390/ijerph18063106] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/29/2021] [Revised: 03/09/2021] [Accepted: 03/16/2021] [Indexed: 12/14/2022]
Abstract
Older adults are particularly vulnerable to cognitive impairment with age, and gender differences are remarkable. However, there is very little evidence to identify both baseline cognitive and occupational gender differences prior to older adults' retirement to design more efficient personalized cognitive interventions. This descriptive observational study examined gender differences in initial cognitive performance in 367 older adults with subjective memory complaints from a primary healthcare center in Zaragoza (Spain). To evaluate initial cognitive performance, the Spanish version of the Mini-Mental State Examination (MEC-35) and the set test were used to measure verbal fluency. Sociodemographic and clinical characteristics were evaluated, and cognitive and occupational differences were analyzed per gender. Men had higher educational and occupational levels, were older and more of them were married (p < 0.001) than women. Regarding cardiovascular risk factors, diabetes and cerebrovascular accidents were more frequent in women, while hypercholesterolemia and obesity were more frequent in men (p < 0.001). High blood pressure was more frequent in women, but not significantly so (p = 0.639). Global cognition was higher in men (p < 0.001) for attention, calculation, and language (p < 0.001). Verbal fluency was higher in women, but the difference was not statistically significant (p = 0.105). These results could be generalized to other health centers in the province and other Spanish autonomous communities as their sociodemographic variables are similar. Individualized interventions that adapt to gender, cognitive and initial occupational performance should be developed and adapted to elderly populations living in the general community to maintain their cognitive capacity and prevent their cognitive impairment and the social health costs this would imply.

Abstract
OBJECTIVE This study investigated whether previously identified modifiable risk factors for dementia were associated with cognitive change in Māori (indigenous people of New Zealand) and non-Māori octogenarians of LiLACS NZ (Life and Living in Advanced Age; a Cohort Study in New Zealand), a longitudinal study. METHOD Multivariable repeated-measure mixed effect regression models were used to assess the association between modifiable risk factors and sociodemographic variables at baseline, and cognitive change over 6 years, with p values of <.05 regarded as statistically significant. RESULTS Modifiable factors associated with cognitive change differed between ethnic groups. Depression was a negative factor in Māori only, secondary education in non-Māori was protective, and obesity predicted better cognition over time for Māori. Diabetes was associated with decreased cognition for both Māori and non-Māori. CONCLUSION Our results begin to address gaps in the literature and increase understanding of disparities in dementia risk by ethnicity. These findings have implications for evaluating the type and application of culturally appropriate methods to improve cognition.

Abstract
Across Latin American and Caribbean countries (LACs), the fight against dementia faces pressing challenges, such as heterogeneity, diversity, political instability, and socioeconomic disparities. These can be addressed more effectively in a collaborative setting that fosters open exchange of knowledge. In this work, the Latin American and Caribbean Consortium on Dementia (LAC-CD) proposes an agenda for integration to deliver a Knowledge to Action Framework (KtAF). First, we summarize evidence-based strategies (epidemiology, genetics, biomarkers, clinical trials, nonpharmacological interventions, networking, and translational research) and align them to current global strategies to translate regional knowledge into transformative actions. Then we characterize key sources of complexity (genetic isolates, admixture in populations, environmental factors, and barriers to effective interventions), map them to the above challenges, and provide the basic mosaics of knowledge toward a KtAF. Finally, we describe strategies supporting the knowledge creation stage that underpins the translational impact of KtAF.

Abstract
BACKGROUND There remains a lack of information and understanding of the prevalence and incidence of Alzheimer's disease and related dementia in Indigenous populations. Little evidence available suggests that Indigenous peoples may have disproportionately high rates of Alzheimer's disease and related dementia (ADRD). OBJECTIVE Given this information, this study systematically explores what risk factors may be associated with ADRD in Indigenous populations. METHODS A search of all published literature was conducted in October 2016, March 2018, and July 2019 using Medline, Embase, and PsychINFO. Subject headings explored were inclusive of all terms related to Indigenous persons, dementia, and risk. All relevant words, phrases, and combinations were used. To be included in this systematic review, articles had to display an association of a risk factor and ADRD. Only studies that reported a quantifiable measure of risk, involved human subjects, and were published in English were included. RESULTS Of 237 articles originally identified through database searches, 45 were duplicates and 179 did not meet a priori inclusion criteria, resulting in 13 studies eligible for inclusion in this systematic review. CONCLUSION The large number of potentially modifiable risk factors reported relative to non-modifiable risk factors illustrates the importance of socioeconomic context in the pathogenesis of ADRD in Indigenous populations. The tendency to prioritize genetic over social explanations when encountering disproportionately high disease rates in Indigenous populations can distract from modifiable proximal, intermediate, and distal determinants of health.

Abstract
Background and Objectives Dementia is a growing public health issue for aging Indigenous populations. Current cognitive assessments present varying degrees of cultural, educational, and language bias, impairing their application in Indigenous communities. Our goal is to provide Anishinaabe communities in Canada with a brief cognitive test that can be administered within the community setting by community health workers or professionals. The purpose of this study was to adapt the Kimberly Indigenous Cognitive Assessment (KICA) for use as a brief cognitive test with Anishinaabe populations in Canada. Research Design and Methods We used a community-based participatory research approach coupled with two-eyed seeing to provide an equitable space for Indigenous knowledge. Adaptation of the KICA was accomplished over 22 months using an iterative cycle of monthly consultations between an 11-member expert Anishinaabe language group (EALG) and the investigators, with ad hoc consultations with an Indigenous Elder, a community advisory council, and the KICA authors. Face validity was established with two pilot studies using cognitive interviewing with Indigenous older adults (n = 15) and a focus group consultation with local health professionals (n = 7). Results Each question of the KICA was scrutinized by the EALG for cultural appropriateness, language and translation, and cultural safety. Every domain required adaptation to reflect cultural values, specificity of language, tone, and a culturally safe approach. Orientation, verbal comprehension and fluency, praxis, and naming domains required the most adaptations. The first pilot for face validity resulted in additional changes; the second confirmed satisfactory adaptation of all changes. Discussion and Implications The research resulted in the new Canadian Indigenous Cognitive Assessment. The findings reveal important cultural and linguistic considerations for cross-cultural cognitive assessment in Indigenous contexts. This new culturally appropriate and safe brief cognitive test may improve case finding accuracy and lead to earlier diagnosis and improved dementia care for Indigenous peoples.

Abstract
Objectives: Dementia is a growing health priority, particularly in less resourced countries and amongst indigenous populations. Understanding cultural meanings ascribed to dementia is an important aspect of policy development and the provision of culturally congruent care and support for people with dementia, their families and the caring professions. This review investigates conceptualizations of dementia amongst indigenous peoples and populations living in low and middle income countries (LMIC), who experience limited diagnosis and formal care for dementia, and how these shape responses to dementia.Methods: A systematic search was conducted for qualitative studies, reported in English, that investigated the perceptions, attitudes or understandings of dementia in LMIC and amongst indigenous populations. A qualitative analysis and meta-synthesis was carried out.Findings: Nineteen articles were included in the review following quality assessment. Dementia was rarely conceptualized as a defined, pathological condition characterized by progressive cognitive decline. Rather, notions of dementia existed within conceptualizations of aging, mental illness, traditional cultural beliefs and the trauma of colonization. Responses to dementia were influenced and perpetuated by community and health providers, and cultural norms for caregiving.Conclusions: There is a need to understand conceptualizations of dementia from the perspective of all stakeholders within a setting, and the dynamic responses that exist between key stakeholders. Community knowledge systems could facilitate understanding about appropriate and acceptable health and community care responses to dementia, and approaches to stigma reduction. Inclusive discussions about dementia are essential if awareness campaigns are to improve the wellbeing of people with dementia and caregivers.

Abstract
This project aims to improve health literacy in Indigenous communities through the development of evidence-based culturally relevant health promotion materials on dementia that bridge the gap between Indigenous and Western perspectives of the illness. The research team worked in partnership with Health Canada's First Nations and Inuit Home and Community Care Program (FNIHCC) and consulted with Indigenous elders to utilize a two-eyed seeing framework that draws upon Indigenous knowledge and Western biomedicine. A consolidated review of materials and research involving Indigenous perspectives of Alzheimer's and age-related dementias led to the development of two culturally appropriate fact sheets. Two Indigenous-specific fact sheets were developed "What is Dementia? Indigenous Perspectives and Cultural Understandings" and "Signs and Symptoms of Dementia: An Indigenous Guide." The fact sheets prioritize Indigenous knowledge and pay particular attention to Indigenous languages, diverse Indigenous cultures, and literacy levels. The content uses phrasing and words from Indigenous people involved in the research to share information. Biomedical concepts and words were included when necessary but language or presentation of these aspects were often modified to reflect Indigenous conceptualizations. This project provides a foundation for evidence-based knowledge translation in relation to cultural safety in dementia care. Specifically, the researchers outline how health care providers can develop culturally appropriate health promotion material, thus increasing Indigenous cultural understandings of dementia and health literacy.

Abstract
BACKGROUND The Asian American, Native Hawaiian, and Pacific Islander (AANHPI) aging population is rapidly growing and the burden of Alzheimer's disease and its related dementias (ADRD) will likely mirror this demographic growth. AANHPIs face significant barriers in obtaining timely ADRD diagnosis and services; yet little is known about ADRD in this population. OBJECTIVE The study objective is to conduct a systematic review on the published literature on ADRD among AANHPIs to identify gaps and priorities to inform future research and action plans. METHODS The systematic review was conducted following the PRISMA Protocol for Systematic Reviews. Co-author (TR), an experienced Medical Librarian, searched PubMed, EMBASE, PsycINFO, Cochrane Central of Clinical Trials, Ageline, and Web of Science for peer-reviewed articles describing ADRD among AANHPIs. The search was not limited by language or publication date. Each citation was reviewed by two trained independent reviewers. Conflicts were resolved through consensus. RESULTS The title/abstract and full texts of 1,447 unique articles were screened for inclusion, yielding 168 articles for analysis. Major research topics included prevalence, risk factors, comorbidities, interventions and outreach, knowledge and attitudes, caregiving, and detection tools. A limited number of studies reported on national data, on NHPI communities generally, and on efficacy of interventions targeting AANHPI communities. CONCLUSION To our knowledge, this is the first systematic review on ADRD among AANHPI populations. Our review provides a first step in mapping the extant literature on ADRD among this underserved and under-researched population and will serve as a guide for future research, policy, and intervention.

Abstract
INTRODUCTION We assessed the sensitivity and specificity of the Modified Mini-Mental State Examination (3MS) in predicting dementia and cognitive impairment in Māori (indigenous people of New Zealand) and non-Māori octogenarians. METHODS A subsample of participants from Life and Living in Advanced Age: a Cohort Study in New Zealand were recruited to determine the 3MS diagnostic accuracy compared with the reference standard. RESULTS Seventy-three participants (44% Māori) completed the 3MS and reference standard assessments. The 3MS demonstrated strong diagnostic accuracy to detect dementia with areas under the curve of 0.87 for Māori and 0.9 for non-Māori. Our cutoffs displayed ethnic variability and are approximately 5 points greater than those commonly applied. Cognitive impairment yielded low accuracy, and discriminatory power was not established. DISCUSSION Cutoffs that are not age or ethnically appropriate may compromise the accuracy of cognitive screens. Consequently, older age and indigeneity increase the risk of mislabeled cognitive status.

Abstract
The importance of better care integration is emphasized in many national dementia plans. The inherent complexity of organizing care for people with dementia provides both the justification for improving care integration and the challenges to achieving it. The prevention, detection, and early diagnosis of cognitive disorders mainly resides in primary care, but how this is best integrated within the range of disorders that primary care clinicians are expected to screen is unclear. Models of integrated community dementia assessment and management have varying degrees of involvement of primary and specialist care, but share an emphasis on improving care coordination, interdisciplinary teamwork, and personalized care. Integrated care strategies in acute care are still in early development, but have been a focus of investigation in the past decade. Integrated care outreach strategies to reduce transfers from long-term residential care to acute care have been consistently effective. Integrated long-term residential care includes considerations of end-of-life care. Future directions should include strategies for training and education, early detection in anticipation of disease modifying treatments, integration of technological developments into dementia care, integration of dementia care into general health and social care, and the encouragement of a dementia-friendly society.

Abstract
OBJECTIVE Ethnicity may affect presentation to clinical services in people with dementia; however, no studies have examined this in Māori or Pacific peoples in New Zealand (NZ). Our objective was to examine the routinely collected clinical data from a memory assessment service in South Auckland to examine the presentation of dementia in the major NZ ethnic groups. METHODS A total of 360 patients presenting to a memory service with a new diagnosis of dementia were included in this study. Demographic data (age, sex, and ethnicity) and dementia sub-type and severity were analyzed. RESULTS There were 142 NZ European (mean age: 79.2, SD 7.4), 43 Māori (mean age: 70.2, SD 7.6), 126 Pacific (mean age: 74.3, SD 7.6), and 49 other ethnicities (mean age: 78.0, SD 8.5) presenting with a new diagnosis of dementia. After adjustment for gender and dementia subtype, Māori and Pacific patients were 8.5 and 5.3 years younger than NZ European patients (P < 0.0001). Pacific peoples tended to present with more advanced dementia (OR = 1.63, 95% CI: 0.98-2.70, P = 0.06) after adjustment for age and gender. There was little difference in the subtypes of dementia between ethnic groups. CONCLUSIONS Māori and Pacific peoples with dementia presented to an NZ memory service at a younger age than NZ Europeans, and Pacific peoples presented with more advanced dementia. A population-based epidemiological study is critical to determine whether Māori and Pacific peoples have indeed a higher risk of developing dementia at a younger age.

Abstract
Many scholars assert that Indigenous peoples across the globe suffer a disproportionate burden of mental illness. Research indicates that colonialism and its associated processes are important determinants of Indigenous peoples' health internationally. In Canada, despite an abundance of health research documenting inequalities in morbidity and mortality rates for Indigenous peoples, relatively little research has focused on mental health. This paper provides a critical scoping review of the literature related to Indigenous mental health in Canada. We searched eleven databases and two Indigenous health-focused journals for research related to mental health, Indigenous peoples, and Canada, for the years 2006-2016. Over two hundred papers are included in the review and coded according to research theme, population group, and geography. Results demonstrate that the literature is overwhelmingly concerned with issues related to colonialism in mental health services and the prevalence and causes of mental illness among Indigenous peoples in Canada, but with several significant gaps. Mental health research related to Indigenous peoples in Canada overemphasizes suicide and problematic substance use; a more critical use of the concepts of colonialism and historical trauma is advised; and several population groups are underrepresented in research, including Métis peoples and urban or off-reserve Indigenous peoples. The findings are useful in an international context by providing a starting point for discussions, dialogue, and further study regarding mental health research for Indigenous peoples around the world.

Abstract
BACKGROUND Ethnic density (the proportion of ethnic minority populations in a geographic area) has emerged as an important factor determining population health. By examining the relationship between mortality rates and the proportion of aboriginal population in Taiwan, this ecological approach highlights the pressing need to understand why aboriginal health remains relatively disadvantaged affecting the population as a whole, especially given the provision of universal health coverage. METHODS Using combined data from various government departments in Taiwan, we first compare overall mortality rates between aboriginal people and the general population in Taiwan's 21 administrative locations during the years 2010 and 2011. Then we describe the associations between ethnic density and the relative risk of 40 different causes of death. RESULTS Aboriginal people in Taiwan on average have higher overall mortality rates than the general population. The proportion of aboriginal population is associated with a higher risk of death for overall mortality, homicide, vehicle crashes, tuberculosis, and several alcohol-related diseases such as peptic ulcer, chronic liver disease, and cirrhosis. These affect the health of the general population in counties where aborigines are abundant. CONCLUSION The proportion of aboriginal population may play an essential role in determining Taiwan's population health. When universal health coverage is in place, the root causes (for example, alcoholism, culture, and socioeconomic disadvantages) of health disparities between aboriginal populations and general populations need to be addressed.

Abstract
In 2014, International Psychogeriatrics (IPG) for the first time introduced a "paper of the month" category as part of the 25th year's milestone celebrations. Papers of the month were chosen through an internal selection process by the IPG editorial team. Each month, the seven editors ranked suitable accepted papers from the categories "original research articles" and "reviews" according to scientific quality and clinical relevance. Each paper of the month was accompanied by a brief commentary written by one of the IPG editors, one of the reviewers for the paper, or an international expert on the specific topic of the paper. From the 12 papers of the month, an IPG paper of the year was selected after a ranking process involving three independent expert reviewers.

Abstract
Indigenous peoples represent up to 5% of the world's population (almost 400 million people), representing thousands of individual cultures and language groups. The health status of older Indigenous peoples has been little researched, partly related to lower life expectancy and the consideration that Indigenous peoples do not live long enough to experience the common “geriatric syndromes” such as dementia, frailty, and falls. Statistics from Australia and Canada now report that Indigenous populations are undergoing rapid aging, with many examples of survivorship to old age (Arkleset al., 2010; Jacklinet al., 2012). The systematic review by Warrenet al. (2015) is a timely one, in that it reminds clinicians interested in old age that this “fourth” World population deserves further attention. Researchers that have worked with these groups to produce population estimates are relatively few. In their systematic review, Warrenet al.(2015) demonstrate wide variation in prevalence rates of dementia. They conclude that a major cause of this heterogeneity in prevalence is due to basic methodological differences. In particular, those studies that have utilized already acquired routine data may be biased. The type and direction of this bias can be complex. For example, Cotteret al.(2012) using routinely collected data, concluded that the prevalence of dementia in Aboriginal Australians in the Northern Territory was not higher than non-Aboriginal prevalence. Using similar methodologies some years later the conclusion was that the Aboriginal population had markedly higher rates (Liet al., 2014). In the intervening period, a dementia awareness campaign coupled with the development of a culturally appropriate screening tool probably resulted in greater detection in routine care.
