“…In another study, native English speakers outperformed non‐native English speakers on several neuropsychological tests, 10 suggesting that delivering tasks in a non‐native language might negatively impact test performance. Similar observations have been reported for many other populations with diverse linguistic abilities, leading to the development of different language‐specific versions of these neuropsychological tests 11–17 . In this context, a plain translation of such tests might not be enough, that is, the transcripted word in another language might have a slightly different conceptual meaning and can bias test results.…”

Projected trends in population aging have forecasted a massive increase in the number of people with dementia, in particular in sub‐Saharan Africa and the Middle East and North Africa (MENA) region. Cognitive decline is a significant marker for dementia, typically assessed with standardized neuropsychological tools that have been validated in some well‐researched languages such as English. However, with the existing language diversity, current tools cannot cater to speakers of understudied languages, putting these populations at a disadvantage when it comes to access to early and accurate diagnosis of dementia. Here, we shed light on the detrimental impact of this language gap in the context of the MENA region, highlighting inadequate tools and an unacceptable lack of expertise for a MENA population of a half billion people. Our perspective calls for more research to unravel the exact impact of the language gap on the quality of cognitive decline assessment in speakers of understudied languages.Highlights Cognitive decline is a marker for dementia, assessed with neuropsychological tests. There is a lack of culturally valid tests for speakers of understudied languages. For example, suboptimal cognitive tests are used in the Middle East and North Africa region. Linguistic diversity should be considered in the development of cognitive tests.

“…One is that the prior study used the modified MINI-COG-PS to detect cognitive impairment, while we used the Thai version of the MoCA, which may have a higher sensitivity for detecting cognitive impairment in older patients. Prior studies conducted in Srinagarind Hospital found that a MoCA score < 20 can diagnose MCI in an outpatient population with 76.2% sensitivity and 71.3% specificity, while the Mini-COG provided only 69% sensitivity and 73% specificity [ 32 , 37 ]. Another possible reason for this discrepancy may be the differences in the studied populations.…”

“…For this study, the Thai version of Montreal Cognitive Assessment test (MoCA-T) was used to evaluate the participants’ cognitive status. A previous study conducted at the Internal Medicine outpatient clinic of Srinagarind Hospital revealed that a MoCA-T score < 20 was an appropriate cut-off point to indicate MCI in older patients in this setting, with a sensitivity of 0.76 and specificity of 0.71 [ 32 ].…”

Frailty is an aging-associated state that increases patients’ vulnerability to disease, and can lead to various adverse outcomes. It is classified as either physical frailty alone or physical frailty in combination with cognitive impairment (cognitive frailty). There are currently limited data available regarding the prevalence and adverse outcomes of frailty in Thailand. This was a cross-sectional study aimed at determining the prevalence of physical and cognitive frailty and their effects on hospitalization and quality of life. Participants were older patients who attended an internal medicine outpatient clinic. Frailty was diagnosed using the Thai Frailty Index. The Thai version of the MoCA was used to evaluate cognitive status. Univariate and multivariate analyses were performed to compare adverse outcomes in terms of poor quality of life and history of admission to hospital between patients with frailty and non-frail patients, and among patients with physical frailty, cognitive frailty, cognitive impairment, and robust (non-frail and non-cognitively impaired) patients. We enrolled 198 participants. The prevalence of physical and cognitive frailty was 28.78% and 20.70%, respectively. When compared with non-frail patients, frailty was associated with hospitalization (adjusted OR 3.01, p = 0.002) but was not significantly related to quality of life (adjusted OR = 1.98, p = 0.09). However, physical and cognitive frailty were associated with fair quality of life when compared with normal patients (adjusted OR = 4.34, p = 0.04 and adjusted OR = 4.28, p = 0.03, respectively). The prevalence of frailty—particularly cognitive frailty—was high. Frailty was associated with adverse outcomes in terms of hospitalization and quality of life.

“…Universal cut-offs can also lead to sampling biases, whereby a cut-off may not match with the individuals being assessed [ 25 ] (e.g., if a target population has a lower level of education or higher rates of illiteracy). As such, this could lead to false conclusions made about an individual’s cognitive ability which could have certain consequences, such as leading to inaccurate diagnosis.…”

Background: The current cognitive tests have been developed based on and standardized against Western constructs and normative data. With older people of minority ethnic background increasing across Western countries, there is a need for cognitive screening tests to address factors which influence performance bias and timely diagnostic dementia accuracy. The diagnostic accuracy in translated and culturally adapted cognitive screening tests and their impact on test performance in diverse populations have not been well addressed to date. Objective: This review aims to highlight considerations relating to the adaptation processes, language, cultural influences, impact of immigration, and level of education to assess for dementia in non-Western and/or non-English speaking populations. Methods: We conducted a systematic search for studies addressing the effects of translation and cultural adaptations of cognitive screening tests (developed in a Western context) upon their diagnostic accuracy and test performance across diverse populations. Four electronic databases and manual searches were conducted, using a predefined search strategy. A narrative synthesis of findings was conducted. Results: Search strategy yielded 2,890 articles, and seventeen studies (4,463 participants) met the inclusion criteria. There was variability in the sensitivity and specificity of cognitive tests, irrespective of whether they were translated only, culturally adapted only, or both. Cognitive test performance was affected by education, linguistic ability, and aspects of acculturation. Conclusions: We highlight the importance of translating and culturally adapting tests that have been developed in the Western context. However, these findings should be interpreted with caution as results varied due to the broad selection of included cognitive tests.
