Abstract
Background Cognitive screening tools are important in the detection of dementia, including Alzheimer's disease; however, they may contain cultural biases. Objective This review examines culture-fair cognitive screening tools and evaluates their screening accuracy, strengths, and limitations. Methods Medline, Embase, PsychINFO and CINAHL were searched. The protocol was registered on PROSPERO (CRD42021288776). Included studies used a culture-fair tool to assess cognition in older adults from varying ethnicities. Narrative synthesis was conducted. Results 28 studies were included assessing eleven different tools. The Rowland Universal Dementia Assessment Scale (RUDAS) was as accurate as the Mini-Mental State Examination (MMSE) (AUC 0.62-0.93), with a similar sensitivity (52-94%) and better specificity (70-98%), and the Multicultural Cognitive Examination (MCE) had improved screening accuracy (AUC 0.99) compared to RUDAS (AUC 0.92). The Visual Cognitive Assessment Test (VCAT) was equivalent to MMSE (AUC 0.84-0.91). The Kimberley Indigenous Cognitive Assessment tool (KICA) had AUC of 0.93-0.95; sensitivity of 90.6%, specificity 92.6%. Conclusions The RUDAS, KICA and VCAT were superior to MMSE for screening dementia in ethnic minorities. Other tools also showed good screening accuracy. Further research should be done to validate tools in different populations.

Abstract
Neurovascular disease such as symptomatic stroke, silent brain infarcts and vascular cognitive impairment are common complications of sickle cell disease (SCD) that can have devastating consequences on quality of life, employment, and social functioning. Early recognition of neurovascular disease is a prerequisite for the timely optimization of medical care and to connect patients to adaptive resources. While cognitive impairment has been well described in children, currently available data are limited in adults. As a result, guidance on the optimal cognitive screening strategies in adults is scarce. We conducted a systematic review to identify the different screening tools that have been evaluated in SCD. A meta-analysis was performed to estimate the prevalence of suspected cognitive impairment in this population. In this qualitative synthesis, we present 8 studies that evaluated 6 different screening tools. Patient characteristics that impacted on cognitive screening performance included age, education level, and a prior history of stroke. We report a pooled prevalence of 38% [14-62%] of suspected cognitive impairment. We discuss the relative benefits and limitations of the different screening tools to help clinicians select an adapted approach tailored to their specific patients' needs. Further studies are needed to establish and validate cognitive screening strategies in patients with diverse cultural and educational backgrounds.

ETHNICITY & HEALTH 2023; 28:757-780. [PMID: 36322705 DOI: 10.1080/13557858.2022.2139818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 10/16/2022] [Indexed: 06/14/2023]
Abstract
OBJECTIVES Research on dementia literacy in Chinese societies is still emerging, and this is especially the case among racially minoritized groups. The present study explored the knowledge, causal beliefs, and help-seeking behaviors of South Asian migrants in Hong Kong about dementia. It also investigated existing community barriers related to dementia knowledge and help-seeking. DESIGN We conducted a qualitative study from a purposive sample of 38 older people and family caregivers from India, Pakistan, and Nepal who lived in Hong Kong. Focus groups and individual in-depth interviews were used to gather information, while thematic analysis was employed to analyze the data. RESULTS Five main themes were identified: normalization with stigmatization of dementia; spiritual and psychosocial attributions of dementia; familial responsibility despite potential caregiving burden; uncertainties versus openness to professional care; and barriers and opportunities in dementia literacy. Ethnic minorities recognized dementia as a disease of normal aging or a mental disorder. They also perceived spiritual and psychosocial factors as their main causes. While participants recognized the potential burden of dementia caregiving, families were their first point of help-seeking, as many of them expressed contrasting feelings of confidence or doubt toward professional services. Utilization of health education strategies, together with collaboration with community leaders, could address the barriers to dementia literacy. CONCLUSIONS This is the first study to explore how ethnic minorities in Asia perceive dementia and its related help-seeking behaviors in their communities. South Asian migrants in Hong Kong have a limited understanding of dementia and may experience delays in obtaining relevant community services. While culture influenced their knowledge, health education may address their misperceptions and help-seeking behaviors toward dementia. Culture- and language-specific programs could also improve dementia knowledge and health service access.

Abstract
The South-East Asia region has one of the fastest-growing aging populations, for which standardized dementia screening measures will be essential for geriatric care. The Rowland Universal Dementia Assessment Scale (RUDAS) is adopted for use in the Indonesian setting but lacks evidence of its cross-cultural transportability. This study aimed to examine the reliability and validity of scores from the Rowland Universal Dementia Assessment Scale (RUDAS) in the Indonesian setting. Indonesian older adults from a geriatric nursing center (N = 135; 52 males, 83 females; age range 60-82) completed the Indonesian translation of the RUDAS (RUDAS-Ina), following content adaptation study with community living older adults (N = 35), nine neurologists and two geriatric nurses. For face and content validity, we utilized a consensus-building procedure. Results following confirmatory factor analysis yielded a single-factor model. The reliability of scores from the RUDAS-Ina was marginally satisfactory for research purposes (Cronbach α = 0.61). Multi-level linear regression for examining the association of the RUDAS-Ina scores with gender and age indicated older age to be associated with lower RUDAS-Ina scores. In contrast, the association with gender was not significant. Findings suggest a need to develop and validate locally generated items with cultural sensitivity to the Indonesian setting, which may also be studied in other Southeast Asian countries.

Abstract
BACKGROUND Primary progressive aphasia (PPA) is a neurodegenerative syndrome characterized by speech and/or language impairment with relatively spared cognition. Research investigating behavioral speech-language intervention and methods for cognitive-linguistic assessment in PPA has predominantly centered around monolingual speakers. This gap hinders the widespread adoption of evidence-based approaches and exacerbates the inequities faced by culturally and linguistically diverse populations living with PPA. OBJECTIVE This scoping review synthesizes the current evidence for assessment and treatment practices in bilingual PPA as well as the operationalization of bilingualism in PPA. METHODS Arksey & O'Malley's scoping review methodology was utilized. Information was extracted from each study and entered into a data-charting template designed to capture information regarding operationalization of bilingualism in PPA and assessment and treatment practices. RESULTS Of the 16 identified studies, 14 reported the results of assessments conducted in both languages. Three studies reported positive naming treatment outcomes. Thirteen studies included English-speaking participants, revealing linguistic bias. Most studies reported age of acquisition, proficiency, and patterns of language use rather than providing an operational definition for bilingualism. CONCLUSIONS Neither formal assessment measures nor clear guidelines for assessment of bilingual PPA currently exist; however, language-specific measures are emerging. Speech-language intervention in bilingual PPA has been relatively unexplored, representing a significant gap in the literature. In order to improve diagnostic and treatment options for bilingual PPA, targeted efforts to increase representation of bilinguals from various sociocultural contexts, as well as those who speak a variety of language pairs, is necessary.

Abstract
Abstract
Background
Routinely collected health administrative data can be used to estimate the prevalence or incidence of dementia at a population level but can be inaccurate. This study aimed to examine the accuracy of hospital and death data for diagnosing dementia compared with a clinical diagnosis in community dwelling older men in Australia.
Methods
We performed a retrospective analysis of the Concord Health and Ageing in Men Project (CHAMP) in Sydney, Australia. Of the 1705 men aged ≥70 years in the CHAMP study, 1400 had available linked administrative data records from 1 year prior to 1 year post the date of clinical dementia diagnosis. The primary outcome was the accuracy of dementia diagnosis using linked administrative data records compared to clinical dementia diagnosis. The linked data diagnosis was based on hospital and death records for the 1 year pre and post the clinical diagnosis. Clinical dementia diagnosis was a two-stage process with initial screening, followed by clinical assessment for those meeting a validated cut-off. A final clinical diagnosis of dementia based on the Diagnostic and Statistical Manual of Mental Disorders (4th edition) criteria was reached by a consensus panel.
Results
Administrative data identified 28 participants as having dementia, compared to 88 identified through clinical assessment. Administrative data had a sensitivity of 20% (95% CI: 13–30%, 18/88), specificity of 99% (95% CI: 99–100%, 1301/1312), positive predictive value (PPV) of 62% (95% CI: 44–77%), negative predictive value of 95% (95% CI: 94–95%), positive likelihood ratio of 24.4 (95% CI: 11.9–50.0) and negative likelihood ratio of 0.80 (0.72–0.89).
Conclusions
Administrative hospital and death data has limited accuracy for dementia diagnosis with poor sensitivity and PPV. The prevalence of dementia is likely underestimated using hospital and deaths data.

Abstract
Objective and accurate cognitive assessment scales are essential for guiding cognitive rehabilitation following traumatic brain injury (TBI). The aim of this study was to evaluate the reliability and validity of the Rowland Universal Dementia Assessment Scale (RUDAS) for TBI and to verify the clinical application value. Fifty patients with TBI and 32 matched controls were assessed using the Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), and a newly developed Chinese version of RUDAS. These scales were then compared for internal consistency, inter-rater reliability, test‒retest reliability, content validity, construct validity, and diagnostic efficacy. Among the TBI group, the RUDAS demonstrated acceptable internal consistency (Cronbach's α = 0.733), high inter-rater reliability (intraclass correlation coefficients [ICCs] of 0.910‒0.999), and high test‒retest reliability (total score ICC = 0.938). The correlation coefficients between RUDAS total score and individual subscores were all > 0.5 except for body orientation (r = 0.363), indicating generally good content validity. Total RUDAS scores were moderately correlated with both MMSE total scores (r = 0.701, p < 0.001) and MoCA total scores (r = 0.778, p < 0.001), indicating good construct validity. Receiving operating characteristic curve analysis yielded comparable areas under the curve for diagnostic efficacy (RUDAS, 0.844; MMSE, 0.769; MoCA, 0.824; all p > 0.05). A RUDAS score cutoff of 23.5 distinguished TBI patients from controls with 60% sensitivity and 100% specificity. Therefore, the RUDAS demonstrates both good reliability and validity for evaluating cognitive impairments in TBI patients.

Abstract
Background: The number of people with a migration background and dementia is increasing in Europe. All patients with suspected dementia have the right to an appropriate cognitive assessment and correct diagnosis for optimal treatment and support. Rowland Universal Dementia Assessment Scale (RUDAS) cognitive screening instrument is less affected by language, culture, and educational background, and adapted for use in multicultural populations. Objective: To compare the diagnostic accuracy of RUDAS-S to the Swedish version of Mini-Mental State Examination (MMSE-SR) for detecting dementia in a multicultural group of outpatients in Swedish memory clinics. Methods: We tested 123 outpatients (36 nonnative Swedish), in 4 memory clinics in Southern Sweden with RUDAS-S to supplement the usual cognitive assessment. Results: RUDAS-S had moderate to good diagnostic performance for detecting dementia in a multicultural population in Sweden, with an area under the receiver operating characteristic curve (AUC) of 0.81. At a cutoff score <25 its sensitivity was 0.92, specificity 0.60, and accuracy 76%. The AUC for the MMSE-SR was 0.79. At a cutoff score <23 its sensitivity was 0.65, specificity 0.81, and accuracy 73%. Conclusion: RUDAS-S is at least as accurate as MMSE-SR for detecting dementia in memory clinics in Sweden and can be used for all patients undergoing a cognitive assessment, irrespective of their cultural, language, and educational background. However, there is a need for other cross-cultural cognitive tests to complement RUDAS-S to extend cognitive examination.

Abstract
While people 65 years of age and older represent 16% of the population in the United States, they account for >40% of surgical procedures performed each year. Maintaining brain health after anesthesia and surgery is not only important to our patients, but it is also an increasingly important patient safety imperative for the specialty of anesthesiology. Aging is a complex process that diminishes the reserve of every organ system and often results in a patient who is vulnerable to the stress of surgery. The brain is no exception, and many older patients present with preoperative cognitive impairment that is undiagnosed. As we age, a number of changes occur in the human brain, resulting in a patient who is less resilient to perioperative stress, making older adults more susceptible to the phenotypic expression of perioperative neurocognitive disorders. This review summarizes the current scientific and clinical understanding of perioperative neurocognitive disorders and recommends patient-centered, age-focused interventions that can better mitigate risk, prevent harm, and improve outcomes for our patients. Finally, it discusses the emerging topic of sleep and cognitive health and other future frontiers of scientific inquiry that might inform clinical best practices.

Abstract
There is now considerable evidence that Transient Ischemic Attack (TIA) carries important sequelae beyond the risk of recurrent stroke, particularly with respect to peri-event and post-event cognitive dysfunction and subsequent cognitive decline. The occurrence of a TIA could provide an important window in understanding the relationship of early mixed vascular-neurodegenerative cognitive decline, and by virtue of their clinical relevance as a "warning" event, TIAs could also furnish the opportunity to act preventatively not only for stroke prevention but also for dementia prevention. In this review, we discuss the current state of the literature regarding the cognitive sequelae associated with TIA, reviewing important challenges in the field. In particular, we discuss definitional and methodological challenges in the study of TIA-related cognitive impairment, confounding factors in the cognitive evaluation of these patients, and provide an overview of the evidence on both transient and long-term cognitive impairment after TIA. We compile recent insights from clinical studies regarding the predictors and mediators of cognitive decline in these patients and highlight important future directions for work in this area.

Abstract
Objectives: Over the lifespan cumulative changes to the brain lead to cognitive decline and eventually to dementia in 20-25% of adults 85 years and older. A commonly used screening tool for cognitive function is the Standard 30 point Mini-Mental State Examination (MMSE). Though the MMSE is used to screen for dementia, little is known about the changes in scores over the lifespan in general populations.Method: A systematic search was conducted using Cochrane, EMBASE, MEDLINE and PsycINFO for articles published from January 1, 2007 to May 25, 2017. Articles were included if they had a longitudinal design reporting at least two MMSE scores. A mixed-effect meta-regression analysis was conducted to examine the influence of age on MMSE score followed by a change-point regression analysis determining the age at which MMSE declines.Results: 45 articles including 58,939 individuals (age range 18-108 years, 61.2% female) summarized 222 MMSE point estimates from 35 cohorts. The meta-regression demonstrated a significant decrease in MMSE scores with higher age (regression coefficient of age: -0.10 (Confidence Interval (CI) -0.15, -0.05)). The average annual decline in MMSE scores identified by the change-point analysis at the age of 41 years and 84 years were -0.04 (95% CI: -0.05, -0.03) and -0.53 (95% CI: -0.55, -0.50), respectively.Conclusions: Between the age of 29 and 105 years MMSE scores decline, with the highest decline between age 84 and 105 years.Clinical Implementations: The use of MMSE should be restricted to higher age categories in aging general populations.

Abstract
AbstractDementia assessment requires functional communication and interaction between healthcare professionals and the patient being assessed. These can be affected by the requirement for an interpreter to communicate with the patient. The purpose of this study was to elucidate the interactions between patient, healthcare professionals and interpreter, focusing on the role of the interpreter and the challenges that may arise in interpreter-mediated dementia assessment. The study had an ethnographic design in which the data consisted of audio and video recordings of 19 dementia assessments conducted in the presence of an interpreter. The data were analyzed using the constant comparative method. The results showed that the interpreter could affect the patient’s performance and results during the dementia assessment. The interpreter could alter the meaning and content of what was communicated, sometimes change information and instructions exchanged between the patient and healthcare professionals, could avoid interpreting everything being said, and occasionally made their own corrections to what was being communicated. This occurred mainly because of the interpreter’s lack of linguistic skills and the interpreter failing to adhere to the ethical guidelines governing their profession. These challenges could also occur when the interpreter was not familiar with the context of dementia assessment. Alterations made by the interpreter to what was being communicated could lead to incorrect evaluation of the patient’s cognitive abilities and health status. This, in turn, may lead to misjudgment of the patient’s remaining resources and symptoms and their required treatment and support.

Abstract
BACKGROUND The Rowland Universal Dementia Assessment Scale (RUDAS) is currently widely used for research and clinical purposes in many countries. However, its applicability and validity have not been evaluated in the Ethiopian context so far. Therefore, we designed this study to assess the reliability and validity of Rowland Universal Dementia Assessment Scale to detect major neurocognitive disorder among older people in Ethiopia. METHODS An institution-based cross-sectional study was conducted among selected older people residing in Macedonia institutional care center, Addis Ababa, Ethiopia. The gold standard diagnosis was determined using the Diagnostic and Statistical Manual of Mental Disorders criteria for major neurocognitive disorders. Stata v16 statistical software was used for data analysis. Receivers operating curve analysis, correlations, linear regression, and independent t-test were performed with statistically significant associations declared at a p-value of <0.05. Inter-rater, internal consistency reliabilities, content, criterion and construct validities were also determined. RESULTS A total of 116 individuals participated in the study with a 100% response rate. Most (52.7%) of the participants were male and the mean age in years was 69.9± 8. The Cronbach's alpha for RUDAS was 0.7 with an intra-class correlation coefficient value of 0.9. RUDAS has an area under the receivers operating curve of 0.87 with an optimal cutoff value of ≤ 22. At this cutoff point, RUDAS has sensitivity and specificity of 92.3 and 75.3 with positive and negative likelihood ratios as well as positive and negative predictive values of 3.7, 0.1, 65.5%, and 91.5%, respectively. There has also been a significant difference in the mean scores of RUDAS among the two diagnostic groups showing good construct validity. CONCLUSION The Rowland Universal Dementia Assessment Scale has been demonstrated to be a valid and reliable tool to detect major neurocognitive disorder. Policy makers and professionals can incorporate the tool in clinical and research practices in developing countries.

Abstract
The Montreal Cognitive Assessment (MoCA) is the commonly used cognitive test for detecting mild cognitive impairment (MCI) in Thailand. Nevertheless, cultural biases and educational levels influence its performance. The Rowland Universal Dementia Assessment Scale (RUDAS) seems to lower the limitation of the MoCA. This study aimed to compare the performance of the RUDAS and the MoCA for the diagnosis of MCI and demonstrate the correlation between them. A cross-sectional study of 150 older participants from the outpatient setting of the Internal Medicine Department, Srinagarind Hospital, Thailand was recruited during January 2020 and March 2021. The diagnostic properties in detecting MCI of the RUDAS and the MoCA were compared. MCI was diagnosed in 42 cases (28%). The AUC for both RUDAS (0.82, 95% CI 0.75-0.89) and MoCA (0.80, 95% CI 0.72-0.88) were similar. A score of 25/30 provided the best cut-off point for the RUDAS (sensitivity 76.2%, specificity 75%) and a score of 19/30 for the MoCA had sensitivity and specificity of 76.2% and 71.3%. The Spearman's correlation coefficient between both tests was 0.6. In conclusion, the RUDAS-Thai could be an option for MCI screening. It was correlated moderately to the MoCA.

Abstract
This study provides a systematic review of linguistically and culturally adapted versions of the original Montreal Cognitive Assessment (MoCA) full version. Adapted versions were identified through a systematic review in 3 databases and on the MoCA website. Overall, 86 culturally different versions of MoCA are available: 74 versions on the MoCA website (25 of them have a corresponding paper concerning the translation process found with the systematic review) and 12 additional versions identified only with the search in biomedical databases. Culturally different adapted versions of the MoCA were unevenly distributed across different geographic areas. The quality of the process of cultural adaptation of MoCA differs considerably among different available versions as well as the number of items adapted in the various language versions. The potential availability of many culturally adapted and translated versions of the MoCA increases the chance of offering a linguistically and culturally sensitive screening for cognitive impairment to diverse populations; further studies are needed to identify if MoCA can be considered a truly cross-cultural fair test.

Abstract
Background: With a growing elderly population worldwide, the prevalence of dementia is rapidly increasing. Studies from high income countries have shown that belonging to a minority ethnic group increases the risk of health disadvantages. Objective: The aim of the present registry-based study was to identify potential differences in diagnostics, treatment, and care of individuals with dementia focusing on foreign-born in Sweden and the impact of country level socioeconomic position (SEP). Methods: The study was based on a large dataset from the Swedish Dementia Registry (SveDem) and the Swedish Tax Agency’s population registry. Data on demographic variables, cognitive tests, clinical assessments, medication, diagnosis, and interventions initiated at diagnosis were collected. Country level SEP was determined by country of birth as classified by World Bank Country and Lending groups. Results: Of 57,982 patients with dementia registered in SveDem, 7,171 (12.4%) were foreign-born. The foreign-born were significantly younger at diagnosis (p < 0.001), had a lower MMSE score (p < 0.001), lower odds of receiving a specific dementia diagnosis (p < 0.001), lower use of acetylcholinesterase inhibitors (p < 0.001), and overall a higher use of neuroleptics compared with the Swedish-born group. The lower SEP, the greater differences to Swedish-born were seen in many of the examined variables. Conclusion: There were significant differences in dementia diagnostics, treatment, and care between foreign-born and Swedish-born, a lower SEP indicating greater differences. Further research should focus on various socioeconomic aspects and health care outcomes for a more profound analysis of equity in dementia care.

Abstract
BACKGROUND Rowland Universal Dementia Assessment Scale (RUDAS) has demonstrated usefulness in cognitive assessment. Studies supporting the use of RUDAS as an evaluation tool in traumatic brain injury (TBI) patients remain limited. This study examined whether the Chinese version of RUDAS can be effectively applied to the cognitive assessment of TBI patients in China. OBJECTIVE To compare the performance of Mini-Mental State Examination (MMSE) and the Chinese version of RUDAS in the cognitive assessment of Chinese patients with TBI so as to provide reference for clinical use. METHODS 86 inpatients with TBI in a hospital were selected from July 2019 to July 2020 and were enrolled as the TBI group, while another 40 healthy individuals matched with age, sex and education level were selected as the control group. All subjects were assessed by trained rehabilitation physicians with MMSE and RUDAS. RESULTS (1) Compared with the control group, the scores of MMSE and RUDAS in the TBI group decreased significantly; (2) The results of MMSE and RUDAS in the TBI group were positively correlated (r = 0.611, P < 0.001); (3) Linear correlation suggested that age was negatively correlated with MMSE (r = -0.344, P = 0.001) and RUDAS (r = -0.407, P < 0.001), while education years were positively correlated with MMSE (r = 0.367, P = 0.001) and RUDAS (r = 0.375, P < 0.001). However, according to the multiple linear regression, the results of RUDAS were not affected by the years of education; (4) Receiver operating curve analysis showed that there was no significant difference in the areas under the curve between MMSE and RUDAS. The best cut-off values of MMSE and RUDAS were 27.5 and 24.5, respectively. CONCLUSIONS MMSE and RUDAS have similar diagnostic efficacy in evaluating cognitive impairment of patients with TBI. Since the Chinese version of RUDAS is not affected by the education level, it is more suitable for TBI patients in China.

Abstract
With an increase in aging populations worldwide, age-related diseases such as Alzheimer's disease (AD) have become a global concern. At present, a cure for neurodegenerative disease is lacking. There is an urgent need for a biomarker that can facilitate the diagnosis, classification, prognosis, and treatment response of AD. The recent emergence of highly sensitive mass-spectrometry platforms and high-throughput technology can be employed to discover and catalog vast datasets of small metabolites, which respond to changed status in the body. Metabolomics analysis provides hope for a better understanding of AD as well as the subsequent identification and analysis of metabolites. Here, we review the state-of-the-art emerging candidate biomarkers for AD.

Diagnostic Accuracy of 10/66 Dementia Protocol in Fijian-Indian Elders Living in New Zealand. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18094870. [PMID: 34063626 PMCID: PMC8124794 DOI: 10.3390/ijerph18094870] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 04/08/2021] [Accepted: 04/30/2021] [Indexed: 11/16/2022]
Abstract
The 10/66 dementia protocol was developed as a language and culture-fair instrument to estimate the prevalence of dementia in non-English speaking communities. The aim of this study was to validate the 10/66 dementia protocol in elders of Indian ethnicity born in the Fiji Islands (Fijian-Indian) living in New Zealand. To our knowledge, this is the first time a dementia diagnostic tool has been evaluated in the Fijian-Indian population in New Zealand. We translated and adapted the 10/66 dementia protocol for use in in Fijian-Indian people. Individuals (age ≥ 65) who self-identified as Fijian-Indian and had either been assessed for dementia at a local memory service (13 cases, eight controls) or had participated in a concurrent dementia prevalence feasibility study (eight controls) participated. The sensitivity, specificity, positive predictive value, and Youden’s index were obtained by comparing the 10/66 diagnosis and its sub-components against the clinical diagnosis (reference standard). The 10/66 diagnosis had a sensitivity of 92.3% (95% CI 70.3–99.5), specificity of 93.8% (95% CI 75.3–99.6), positive predictive value of 92.3% (95% CI 70.3–99.5), and negative predictive value of 93.8% (95% CI 75.3–99.6). The study results show that the Fijian-Indian 10/66 dementia protocol has adequate discriminatory abilities to diagnose dementia in our sample. This instrument would be suitable for future dementia population-based studies in the Fijian-Indian population living in Aotearoa/New Zealand or the Fiji-Islands.

Abstract
IMPORTANCE Adults with sickle cell disease (SCD) disproportionally experience early cognitive decline; however, guidance on the optimal screening strategy for cognitive dysfunction is lacking, and several available tools are biased by language, educational level, socioeconomic status, and race/ethnicity. The Rowland Universal Dementia Assessment Scale (RUDAS) was specifically designed for cognitive screening in multicultural populations. OBJECTIVE To ascertain the prevalence of suspected dementia in adults with SCD using the RUDAS, and to identify whether age, sex, educational level, several biological variables, and SCD complications were associated with RUDAS scores. DESIGN, SETTING, AND PARTICIPANTS This multicenter, bilingual, cross-sectional study was conducted in 2 SCD comprehensive care centers in Canada (Centre Hospitalier de l'Université Montréal in Montréal and University Health Network in Toronto). Participants were adults aged 18 years or older and were enrolled in the study between July 1, 2018, and July 30, 2019. All outpatients were eligible and offered study participation, unless they had an acute medical condition that required inpatient care or they were unable to follow study instructions. INTERVENTIONS The RUDAS was administered by trained personnel in either French or English, according to the patient's language preference. A questionnaire on social determinants of health was also administered, and participants underwent screening for anxiety and depression. MAIN OUTCOMES AND MEASURES Proportion of participants with RUDAS scores that were suggestive of dementia and the RUDAS score. Any score lower than 23 points was suggestive of dementia, a score between 23 and 27 points indicated a possible association with mild neurocognitive disorder, and a score higher than 27 points was normal. RESULTS A total of 252 adult patients with SCD were included (136 women [54.0%]; mean [range] age, 34.8 [18-75] years). Overall, 29 patients (11.5%) had RUDAS scores that were suggestive of dementia, and this proportion increased with age (15 [8.7%] in the 18-39 years age group, 10 [14.5%] in the 40-59 years age group, and 4 [36.4%] in the ≥60 years age group). The RUDAS scores were not associated with sex, language, SCD genotype, and SCD complications. The highest level of education was significantly associated with the RUDAS score; however, the association was small (η2 = 0.02; 95% CI, 0.00-0.07; P = .02). In a multivariable analysis, lower glomerular filtration rate (r = 0.40; 95% CI, 0.29-0.50; P < .001) and increasing age (r = -0.37; 95% CI, -0.47 to -0.26; P < .001), but not SCD genotype or disease severity, were associated with lower RUDAS scores. CONCLUSIONS AND RELEVANCE This study found that using the RUDAS revealed a high prevalence of suspected dementia in adult patients with SCD that was associated with worsening kidney function and age. Cognition should be screened in all adult patients with SCD, regardless of age, disease severity, and SCD genotype; further validation of the RUDAS is ongoing.

Abstract
IMPORTANCE Trivalent adjuvanted inactivated influenza vaccine (aIIV3) and trivalent high-dose inactivated influenza vaccine (HD-IIV3) are US-licensed for adults aged 65 years and older. Data are needed on the comparative safety, reactogenicity, and health-related quality of life (HRQOL) effects of these vaccines. OBJECTIVE To compare safety, reactogenicity, and changes in HRQOL scores after aIIV3 vs HD-IIV3. DESIGN, SETTING, AND PARTICIPANTS This randomized blinded clinical trial was a multicenter US study conducted during the 2017 to 2018 and 2018 to 2019 influenza seasons. Among 778 community-dwelling adults aged at least 65 years and assessed for eligibility, 13 were ineligible and 8 withdrew before randomization. Statistical analysis was performed from August 2019 to August 2020. INTERVENTIONS Intramuscular administration of aIIV3 or HD-IIV3 after age-stratification (65-79 years; ≥80 years) and randomization. MAIN OUTCOMES AND MEASURES Proportions of participants with moderate-to-severe injection-site pain and 14 other solicited reactions during days 1 to 8, using a noninferiority test (5% noninferiority margin), and serious adverse events (SAE) and adverse events of clinical interest (AECI), including new-onset immune-mediated conditions, during days 1 to 43. Changes in HRQOL scores before and after vaccination (days 1, 3) were also compared between study groups. RESULTS A total of 757 adults were randomized, 378 to receive aIIV3 and 379 to receive HD-IIV3. Of these participants, there were 420 women (55%) and 589 White individuals (78%) with a median (range) age of 72 (65-97) years. The proportion reporting moderate-to-severe injection-site pain, limiting or preventing activity, after aIIV3 (12 participants [3.2%]) (primary outcome) was noninferior compared with HD-IIV3 (22 participants [5.8%]) (difference -2.7%; 95% CI, -5.8 to 0.4). Ten reactions met noninferiority criteria for aIIV3; 4 (moderate-to-severe injection-site tenderness, arthralgia, fatigue, malaise) did not. It was inconclusive whether these 4 reactions occurred in higher proportions of participants after aIIV3. No participant sought medical care for a vaccine reaction. No AECI was observed. Nine participants had at least SAE after aIIV3 (2.4%; 95% CI,1.1% to 4.5%); 3 had at least 1 SAE after HD-IIV3 (0.8%; 95% CI, 0.2% to 2.2%). No SAE was associated with vaccination. Changes in prevaccination and postvaccination HRQOL scores were not clinically meaningful and not different between the groups. CONCLUSIONS AND RELEVANCE Overall safety and HRQOL findings were similar after aIIV3 and HD-IIV3, and consistent with prelicensure data. From a safety standpoint, this study's results support using either vaccine to prevent influenza in older adults. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03183908.

Abstract
BACKGROUND Cognitive assessment is an essential element of the screening process of Alzheimer's disease. The prevalence of dementia is increasing and so are the numbers of immigrants and elderly population relocating and in need for health diagnosis and treatment. However, most of the psychometric tools used in psychological assessments are time-consuming and suffer from biases of language and cultural restrictions. OBJECTIVES Our objective was to create a computerized version of a multicultural cognitive screening test, which would simplify cognitive assessment of elderly multicultural population, as routine part of health check-up procedures. METHODS The application was implemented in Android Studio and was written in Java code with the use of a home PC and a tablet. Rowland Universal Dementia Assessment Scale (RUDAS) was chosen. RUDAS is a cognitive screening tool with good psychological characteristics, which was created for multicultural and bilingual populations and was free to download. The collaboration with an authorized psychologist was essential for the ethics of the psychometric science. RESULTS The complete computerized version of RUDAS will include the six-item questionnaire, assessing specific cognitive domains which are in high correlation with Alzheimer's screening process, such as registration, visuospatial orientation, praxis, visuo-constructional drawing, judgment, memory recall and language. CONCLUSION The utilization of informatics in making cognitive assessment a user-friendly, validated, not time- or cost-consuming procedure would add value to psychometric tools which still are administered with "pen and paper", when this proceeds with respect to the ethics of the science.

Abstract
OBJECTIVES To quantitatively synthesize data on the accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) in different sociocultural settings and compare its performance to other brief screening instruments for the detection of dementia. DESIGN Systematic review and meta-analysis. Literature searches were performed in PubMed, EMBASE, and CINAHL from January 1, 2004 until September 1, 2019. SETTING Community, outpatient clinic, and hospital settings in high-, and low- and middle-income countries. PARTICIPANTS Twenty-six studies reporting diagnostic accuracy of the RUDAS were included with almost 4000 participants, including approximately 1700 patients with dementia. MEASUREMENTS Procedures for translation and cultural adaption of the RUDAS, and influence of demographic variables on diagnostic accuracy, were compared across studies. Bivariate random-effects models were used to pool sensitivity and specificity results, and diagnostic odds-ratios and the area under the hierarchical summary receiver operator characteristic curve were used to present the overall performance. RESULTS The pooled sensitivity and specificity for the detection of dementia were .82 (95% CI, .78-.86) and .83 (95% CI, .78-.87), respectively, with an area under the curve of .89. Subgroup analyses revealed that the RUDAS had comparable diagnostic performances across high-, and low- and middle-income settings (z = .63, P = .53) and in samples with a lower and higher proportion of participants with no formal education (z = -.15, P = .88). In 11 studies making direct comparison, the diagnostic performance of the RUDAS was comparable to that of the Mini-Mental State Examination (z = -.82, P = .41), with areas under the curve of .88 and .84, respectively. CONCLUSIONS The RUDAS has good diagnostic performance for detecting dementia in different sociocultural settings. Compared to other brief screening instruments, advantages of the RUDAS include its limited bias in people with limited or no formal education and a minimal need for cultural or language adaptation.

Abstract
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.

Abstract
Every year, millions of patients worldwide undergo cognitive testing. Unfortunately, new barriers to the use of free open access cognitive screening tools have arisen over time, making accessibility of tools unstable. This article is in follow-up to an editorial discussing alternative cognitive screening tools for those who cannot afford the costs of the Mini-Mental State Examination and Montreal Cognitive Assessment (see www.dementiascreen.ca). The current article outlines an emerging disruptive "free-to-fee" cycle where free open access cognitive screening tools are integrated into clinical practice and guidelines, where fees are then levied for the use of the tools, resulting in clinicians moving on to other tools. This article provides recommendations on means to break this cycle, including the development of tool kits of valid cognitive screening tools that authors have contracted not to charge for (i.e., have agreed to keep free open access). The PRACTICAL.1 Criteria (PRACTIcing Clinician Accessibility and Logistical Criteria Version 1) are introduced to help clinicians select from validated cognitive screening tools, considering barriers and facilitators, such as whether the cognitive screening tools are easy to score and free of cost. It is suggested that future systematic reviews embed the PRACTICAL.1 criteria, or refined future versions, as part of the standard of review. Methodological issues, the need for open access training to insure proper use of cognitive screening tools, and the need to anticipate growing ethnolinguistic diversity by developing tools that are less sensitive to educational, cultural, and linguistic bias are discussed in this opinion piece.

Abstract
Nowadays, Alzheimer's disease (AD) diagnosis is considered to be a crucial and extremely complex process. Nevertheless, psychometric tools, like Mini-Mental State Evaluation (MMSE), are used to address cognitive function assessment and clinical evaluation processes. However, MMSE's sensitivity in the diagnosis of mild cognitive impairment is debatable in terms of education, age, or nationality. Typical psychometric tools with the use of "paper and pencil" methods combined with physiology measurements are proposed in order to enhance validity and effectiveness in the case of Alzheimer's disease cognitive deficits. The objective of this review study is to highlight the effectiveness of brief cognitive tests (BCT) in the case of dementia and Alzheimer's disease screening. Authors' future work will focus on the application of BCT in MCI diagnosis and evaluation.

Abstract
Objectives: To evaluate the performance of the Peruvian version of the Rowland Universal Dementia Assessment Scale (RUDAS-PE) in discriminating between controls and patients with mild cognitive impairment (MCI) and dementia in an illiterate population with low-levels of education. Methods: We compared the cognitive performance of 187 elderly subjects who were illiterate (controls n = 60; MCI n = 64; dementia n = 63). Neuropsychological measures included the RUDAS-PE, Mini-Mental State Examination (MMSE), INECO Frontal Screening (IFS), and Pfeffer Functional Activities Questionnaire (PFAQ). The results were compared to a neuropsychological evaluation (gold standard), including use of Clinical Dementia Rating (CDR) scores. Results: We found a Cronbach's alpha was 0.65; Spearman's correlation coefficient was 0.79 (p < 0.01). The area under the receiver operating characteristics curve for the RUDAS to discriminate dementia from MCI was 98.0% with an optimal cut-off <19 (sensitivity 95%, specificity 97%); whereas, to differentiate MCI and controls was 98.0% with an optimal cut-off <23 (sensitivity 89%, specificity 93%). Conclusions: Based on its excellent psychometric properties, we find the RUDAS-PE suitable to aid in the opportune detection of dementia in a geriatric illiterate population with low-levels of education.

Abstract
INTRODUCTION Evidence in the literature demonstrates the reliability of cognitive screening assessments using video technology in English-speaking older populations. However, this has not been tested in older culturally and linguistically diverse (CALD) populations who require an interpreter, and what the associated costs would be. The aim was to determine if the Rowland Universal Dementia Assessment Scale (RUDAS) and the Geriatric Depression Scale (GDS) could be reliably administered over video-interpreting methods compared with face-to-face interpreting. In addition, the study aims to compare the costs of video-interpreting with the costs of face-to-face interpreting. METHODS We compared similarity of the RUDAS and GDS scores when administered face-to-face and via video-interpreting. The similarity of scores between methods was analysed using paired t-tests and Bland-Altman plots. A costing analysis was done using a micro-costing approach to estimate the costs of video-interpreting compared with face-to-face, extrapolated to a national level. RESULTS Analysis found no significant differences in the mean assessment scores between video-interpreting and face-to-face (RUDAS mean difference: -0.36; 95% confidence interval (CI): -1.09, 0.38, GDS mean difference: 0.22; 95% CI: -0.38, 0.83). Bland-Altman plots demonstrated that 71% of RUDAS scores and 82% of GDS scores were within the maximum allowed difference of ±2 units. Costing analysis showed a A$7 saving per assessment when using video-interpreting compared with face-to-face, with a total national saving of A$247,350. DISCUSSION Video-interpreting was found to be as reliable as face-to-face interpreting for both RUDAS and GDS assessments. Cost analysis indicates that video-interpreting is cheaper than face-to-face interpreting.

Abstract
OBJECTIVE Detecting dementia in people who are illiterate or have a low level of education is complicated because many cognitive screening tests are not suitable for these persons. Caregiver or informant-based judgment of cognitive status may aid diagnosis. Our goal was to investigate the diagnostic accuracy of the Informant Questionnaire for Cognitive Decline in the Elderly (IQCODE) in a population of elderly non-Western migrants with a high illiteracy rate. Second, we wanted to investigate the diagnostic accuracy of IQCODE and Rowland Universal Dementia Screening (RUDAS) combined. METHOD 109 geriatric outpatients and 20 community controls were included. Geriatricians provided a research diagnosis of intact cognition (n = 27), mild cognitive impairment (MCI; n = 33) or dementia (n = 49). Diagnostic accuracy was calculated for the clinical sample (n = 109). ROC curves for prediction of group status for IQCODE, RUDAS and the combination of both were created. RESULTS Predictive validity was high for both IQCODE and RUDAS and was highest for the combination (Area Under the Curve .91). Sensitivity, specificity, Youden index, predictive value, and likelihood ratio for IQCODE and RUDAS are reported. CONCLUSIONS In this study in non-Western elderly migrants, half of whom were illiterate, the IQCODE proved to be a valid instrument for dementia detection, and adding the RUDAS increased accuracy. Combining performance-based and informant-based data is recommended to enhance diagnostic precision.

Abstract
Good communication is essential in neurological consultations, yet this is obviously compromised by the absence of a common language. Interpreters can make valuable contributions to improving consultations, but translation has its shortcomings. The consultation dialogue is not always interpreted correctly or accurately, even (or especially) when friends or family are translating. Clinicians should therefore try to ensure that key information has been communicated and understood, perhaps by repetition or asking the patient to say what they have understood. Cultural factors are also important in the patient–physician interaction. Physicians should try to adopt a culturally sensitive approach during consultations, familiarising themselves with cultural norms within the prevalent ethnic minority groups in their area. They should resist directive approaches to save time and try to involve the patient in decision-making. This requires allocating extra time to consultations with patients for whom English is not their first language.

Abstract
OBJECTIVES To assess the psychometric properties of the Peruvian version of the Rowland Universal Dementia Assessment Scale (RUDAS-PE) to discriminate controls from patients with mild cognitive impairment (MCI) and early dementia (ED) in a population with a mid-level education. METHODS A total of 133 patients from a memory clinic were administered the RUDAS-PE, INECO Frontal Screening, Addenbrooke's Cognitive Examination, and Mini-Mental State Examination. Results were compared against a neuropsychological evaluation (gold standard). Validity measures, internal consistency, and concurrent validity were calculated. RESULTS Cronbach's α was 0.68; Pearson's ratio was 0.79 (P < .01). The area under the receiver-operating characteristics curve of the RUDAS to discriminate between ED and MCI was 89.0% (optimal cutoff at <21), whereas between MCI and controls, it was 99.0% (optimal cutoff at <24). CONCLUSIONS The RUDAS-PE has acceptable psychometric properties performing well in its ability to discriminate controls from patients with MCI and ED.

Abstract
Background Mild Cognitive Impairment (MCI) is a transitional state between normal cognition and dementia during ageing process. Early screening of elderly for MCI can help for early prevention and treatment of dementia. Rowland Universal Dementia Assessment Scale (RUDAS) is a brief cognitive assessment tool with excellent psychometric properties and is particularly useful in culturally and linguistically diverse (CALD) populations. The purpose of this study was to translate RUDAS into Nepali and to evaluate internal consistency of Nepali version of RUDAS. Methods RUDAS was translated to Nepali following recommended guidelines for translation and cross-cultural adaptation of patient reported measures. The pre-final Nepali version of RUDAS was tested on 30 elderly and appropriate changes were made by expert committee. The final Nepali version of RUDAS was developed and was administered on 100 elderly populations (mean age 67.70) to assess internal consistency. Results The rating of the participants upon their understanding of each 6 items of Nepali version of RUDAS on a 10-point Likert scale received a good score of more than 8 except ‘cube drawing’ which only received a mean score of 5.5. Additionally, only 8(27%) elderly have responded to the item ‘cube drawing’. The preference test was done and cube drawing was replaced by stick design test. Nepali version of RUDAS showed acceptable internal consistency with Cronbach’s alpha 0.7. Conclusion The results of our study presents translated and cross-culturally adapted Nepali version of RUDAS that has been proved to be an appropriate assessment tool for screening cognitive impairment among elderly.

Abstract
BACKGROUND The aims of this study were to present the psychometric properties of a newly designed cognitive screening instrument, the Multicultural Cognitive Examination (MCE), and to compare it with the Rowland Universal Dementia Assessment Scale (RUDAS) in a multicultural population. METHODS The study was a Western European cross-sectional multicenter study. The MCE consists of four components evaluating separate cognitive functions and was constructed by adding measures of memory, verbal fluency, and visuospatial function to the RUDAS to create a scale with 0 to 100 points. RESULTS A total of 66 patients with dementia and 123 cognitively intact participants were included across six memory clinics; 96 had minority ethnic background, and 93 had majority ethnic background. Moderate to large differences were present between patients with dementia and control participants on all MCE components. The MCE significantly improved diagnostic accuracy compared with using the RUDAS alone, with area under the curves of .918, .984, and .991 for the RUDAS, MCE composite, and demographically corrected composite scores, respectively. Diagnostic accuracy of the MCE did not significantly differ between minority and majority ethnic groups. Across MCE subcomponents, patients with Alzheimer's disease (AD) dementia performed significantly poorer on the memory component compared with those with non-AD dementia. CONCLUSIONS The MCE is a brief cross-cultural cognitive screening instrument that expands evaluation of the cognitive functions covered by the RUDAS, does not require any specialized training, and may be useful for classification of mild dementia or dementia subtypes.

Abstract
OBJECTIVE The objective of this study was to identify relevant outcomes and measures to inform a systematic review (SR) on the comparative effectiveness of geriatrician-led care models. STUDY DESIGN AND SETTING In the modified Delphi to select outcomes for inclusion in the SR, knowledge users (KUs) from Ontario, Alberta, and Saskatchewan rated outcome importance using a Likert scale. A survey was then completed by geriatricians to determine optimal measures for selected outcomes. Findings were analyzed using frequencies, means, and standard deviations (SDs). RESULTS Thirty-three KUs (patients, caregivers, policymakers and geriatricians) rated 27 outcomes in round 1 of the modified Delphi. Top-rated outcomes included function (mean 6.85 ± SD 0.36), cognition (6.47 ± SD 0.72), and quality of life (6.38 ± SD 0.91). Twenty-three KUs participated in round 2 and rated 24 outcomes. Top-rated outcomes in round 2 were function (6.87 ± SD 0.34), quality of life (6.45 ± SD 1.10), and cognition (6.43 ± SD 0.73). The survey was completed by 22 geriatricians and the highest ranked measures were Activities of Daily Living (function), Mini-Mental State Examination (cognition), and the Medical Outcomes Study SF-36 (quality of life). CONCLUSION We identified the most relevant outcomes and measures for patients, caregivers, policymakers, and geriatricians, allowing us to tailor the SR to KU needs.

Abstract
UNLABELLED ABSTRACTBackground:With increasing cultural diversity and growing elderly immigrant populations in Western European countries, the availability of brief cognitive screening instruments adequate for assessment of dementia in people from diverse backgrounds becomes increasingly important. The aim of the present study was to investigate diagnostic accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) in a multicultural sample and to calculate normative data as a basis for demographic adjustment of RUDAS scores. METHODS The study was a prospective international cross-sectional multi-center study. Receiver operating characteristic curve analysis was used to examine diagnostic accuracy. Regression analysis was used to assess the impact of demographic variables. RESULTS Data was collected from 341 cognitively intact participants and 80 people with dementia with a wide age- and educational range. Of the 421 included participants, 239 (57%) had immigrant background. The RUDAS had high diagnostic accuracy with an area under the curve (AUC) of 0.93. The optimal cut-off score was <25 (sensitivity 0.80, specificity 0.90). Regression analysis revealed that RUDAS scores were mainly affected by education and were unrelated to data collection site and immigrant status. Education-adjusted normative data was calculated as a basis for education adjustment of RUDAS scores. Applying education-adjusted RUDAS scores slightly but significantly improved diagnostic accuracy with an AUC of 0.95. CONCLUSION We found the RUDAS to have excellent diagnostic properties in our multicultural sample. However, we suggest that RUDAS scores should be adjusted for education to increase diagnostic accuracy and that the choice of cut-off score should be considered based on the clinical context and expected base rate of dementia.

Abstract
BACKGROUND The aim is to validate Turkish version Rowland Universal Dementia Assessment Scale (RUDAS). METHODS One hundred forty patients (>65 years) were included. Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition -V was used in all patients. Rowland Universal Dementia Assessment Scale was applied for 2 days. Results were compared with Mini-Mental State Examination; reliability, validity, and statistical values were determined. RESULTS Time validity was verified. Mini-mental state examination was correlated 45.3% in control and 73% in dementia group. Factor weights varied between 0.44 and 0.81; factor construct was verified as 6-item scoring. When 25 was cutoff point, sensitivity was 92.86% and specificity was 92.86%. Content validity index was found to be 100% by 7 specialists. Cronbach α (0.692) and test-retest reliability (intraclass correlation = 0.987) were determined. CONCLUSION Rowland Universal Dementia Assessment Scale (Turkish) is validated and verified as reliable. Test could be applied for 5 minutes approximately; results are not affected by educational status, immigrant status, and language used; however, age and gender have significant effect on results.

Abstract
BACKGROUND The aims of this study were to establish the diagnostic accuracy of the European Cross-Cultural Neuropsychological Test Battery (CNTB) for dementia in different ethnic populations in Western Europe, to examine its ability to differentiate cognitive impairment profiles for dementia subtypes, and to assess the impact of demographic variables on diagnostic properties. METHODS The study was a Western European cross-sectional multi-center study. A total of 66 patients with dementia and 118 cognitively intact participants were included across six memory clinics; 93 had ethnic minority background and 91 had ethnic majority background. Tests in the CNTB cover global cognitive function, memory, language, executive functions, and visuospatial functions. RESULTS Significant differences with moderate to large effect sizes were present between patients with dementia and control participants on all CNTB measures. Area under the curves (AUC) ranged from .62 to .99 with a mean AUC across all measures of .83. Comparison of ethnic minority and majority groups generally revealed higher sensitivity in the minority group but no significant difference in the mean AUC's across all measures (.84 vs78, P = .42). Comparison of impairment profiles for patients with Alzheimer's disease (AD) and non-AD dementia revealed that AD patients were significantly more impaired on the memory domain, whereas patients with non-AD dementia were more impaired on the executive functions domain. CONCLUSIONS The CNTB was found to have promising cross-cultural diagnostic properties for evaluation of dementia in the targeted minority and majority populations and could represent a valid cross-cultural alternative to other well-established neuropsychological test batteries when assessing patients from these populations.

Abstract
Approximately 47 million people have dementia worldwide, with this figure, it is expected to almost triple by 2050. Most people with dementia (approximately two-thirds) live in low- and middle-income countries (LMICs). This presents a significant challenge for such countries that often have limited financial resources and less well-developed health and social care systems. In the absence of a cure, reducing the future costs of dementia care and burden of disease may be best achieved by a greater emphasis on (1) more timely diagnosis with earlier intervention to maintain functional independence and (2) undertaking "screening" in groups at high risk of developing dementia, case finding, and using brief cognitive assessment instruments. In clinical settings, a wide range of instruments for dementia screening and diagnosis are currently available; however, few cognitive assessment tools have been developed specifically for clinical use within LMIC settings. Screening for dementia and cognitive impairment in LMICs largely relies on tools adapted from high-income countries (HICs); these often lack validation in these settings leading to education, literacy, and cultural biases. Research is urgently needed to develop cognitive assessment tools and dementia diagnostic approaches that are appropriate and feasible for clinical use in LMIC settings.

Abstract
Background Along with the ageing of the general population, Europe’s migrant populations are also ageing, thus posing new challenges for dementia care services, particularly if the services are to be adjusted to persons with different linguistic and cultural backgrounds. From the perspective of health professionals, this study aims to explore challenges involved in identifying, assessing and diagnosing people with cognitive impairment/dementia who have different linguistic and cultural backgrounds. Methods Research on health professionals experiences regarding the management of dementia among immigrants is scarce and qualitative methods was used to address the objective of the study. Using qualitative in-depth interviews and focus-group discussions, we sought to gather participants’ experiences regarding the diagnostic process for immigrants with dementia. The material was analysed and interpreted based on Kvale and Brinkmann’s descriptions of three different contexts of interpretation: self-understanding, critical common-sense understanding, and theoretical understanding. Results Health professionals described how families could attribute symptoms of dementia to processes of normal ageing, while others saw the symptoms as something shameful; both instances delayed or hindered help-seeking. Many clinicians had limited experience with older immigrants suffering from dementia, and general practitioners (GPs) in particular experienced difficulties assessing dementia due to language barriers and difficulties related to the involvement of the family or an interpreter. The findings illustrate challenges in assessment, such as unfamiliarity with test situations among those being assessed and lack of knowledge regarding appropriate diagnostic tools among health professionals. Lack of continuity and poor information exchange in the chain of care seem to reinforce many of these challenges. Conclusions Detection, treatment and care may be improved if primary care professionals strengthen their cross-cultural competences. Training in communication skills and in the use of cross-cultural assessment tools may help build competence and confidence when assessing and caring for people with different cultural and linguistic backgrounds. Closer collaboration among families, nurses in home-based services, dementia teams, and GPs may facilitate close monitoring of a patient over time. Such collaboration requires sufficient information exchange during transitions in the chain of care, continuity among health professionals, and a shared understanding of the goals for treatment and care.

Abstract
Background Diagnosing dementia in elderly immigrants is often difficult due to language and cultural barriers, low education, and illiteracy. We compared the diagnostic accuracy of the Rowland Universal Dementia Assessment Scale (RUDAS) to that of the Mini Mental State Examination (MMSE). Methods A total of 144 patients (42 with intact cognition, 44 with mild cognitive impairment [MCI], and 58 with dementia) were administered both instruments and were diagnosed by specialists blinded for MMSE and RUDAS results. Results Areas under the curve for discriminating intact cognition from MCI and dementia were comparable for RUDAS (0.81; 95% confidence interval 0.74–0.88) and MMSE (0.75; 95% confidence interval 0.69–0.85). Education and literacy were not correlated with the RUDAS but had a medium-large correlation with the MMSE (rho = 0.39). Conclusions The study provides additional evidence for the usefulness of the RUDAS in a highly illiterate, culturally diverse geriatric outpatient population.

Abstract
BACKGROUND Our aim was to evaluate and compare the diagnostic properties of 5 screening tests for the diagnosis of mild Alzheimer disease (AD). METHODS We conducted a prospective and cross-sectional study of 92 patients with mild AD and of 68 healthy controls from our Department of Neurology. The diagnostic properties of the following tests were compared: Mini-Mental State Examination (MMSE), Addenbrooke's Cognitive Examination III (ACE-III), Memory Impairment Screen (MIS), Montreal Cognitive Assessment (MoCA), and Rowland Universal Dementia Assessment Scale (RUDAS). RESULTS All tests yielded high diagnostic accuracy, with the ACE-III achieving the best diagnostic properties. The area under the curve was 0.897 for the ACE-III, 0.889 for the RUDAS, 0.874 for the MMSE, 0.866 for the MIS, and 0.856 for the MoCA. The Mini-ACE score from the ACE-III showed the highest diagnostic capacity (area under the curve 0.939). Memory scores of the ACE-III and of the RUDAS showed a better diagnostic accuracy than those of the MMSE and of the MoCA. All tests, especially the ACE-III, conveyed a higher diagnostic accuracy in patients with full primary education than in the less educated group. Implementing normative data improved the diagnostic accuracy of the ACE-III but not that of the other tests. CONCLUSIONS The ACE-III achieved the highest diagnostic accuracy. This better discrimination was more evident in the more educated group.

Abstract
PURPOSE OF REVIEW This article presents a clinically useful approach to obtaining the history and performing the mental status examination of patients with cognitive, language, or behavioral problems. RECENT FINDINGS Laboratory and imaging biomarkers are being developed for accurate diagnosis of neurobehavioral disorders, yet few are currently available for clinical use. Moreover, not all centers have access to these potential tools. Practicing clinicians are therefore left primarily with their skills of history taking and examination. Although geared for research, diagnostic criteria have been refined over the past several years and can nevertheless aid the clinician with the diagnosis of disorders such as mild cognitive impairment, Alzheimer disease, frontotemporal dementia, dementia with Lewy bodies, the primary progressive aphasias, corticobasal syndrome, vascular cognitive impairment, and posterior cortical atrophy. Regularly revised criteria reflect ongoing knowledge gained from in-depth studies of these disorders. SUMMARY The focused history and mental status examination remain essential tools for the evaluation and diagnosis of neurologic disorders affecting cognition, language, and behavior.

Abstract
Purpose
The paper aims to investigate if the performance of older adults on the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA) were associated or predictive of their functional performance in a geriatric evaluation and management (GEM) inpatient hospital setting. This will inform the occupational therapy assessment and management of older adults admitted to sub-acute GEM settings.
Design/methodology/approach
In all, 20 participants (11 men, 9 women, mean age 82 years, SD = 6.93) were recruited from a GEM ward in an Australian hospital. Participants’ cognitive abilities were assessed using the MMSE and MoCA, and their functional performance were assessed using the Functional Independence Measure (FIM). Spearman’s rho correlations and linear regression analyses were completed. Bootstrapping was applied to the regression analyses to accommodate the small study sample size.
Findings
No statistically significant correlations were obtained between the total and subscale scores of the MMSE and FIM or between the total and subscale scores of the MoCA and FIM. In other words, the cognitive and functional abilities of older adults admitted to a GEM setting were not significantly associated in this study.
Originality/value
The findings suggest that the MoCA and the MMSE were not predictive of participants’ functional performance as measure by the FIM in a sub-acute GEM setting. Occupational therapists should be cautious when interpreting participants’ MMSE, MoCA and FIM results and not depend solely on these results in the goal setting and intervention planning processes for clients on GEM wards. Further studies are recommended to confirm these findings.
