“…One study (N=66) differentiating MCI from controls in Japan [52] suggested a cut off of 25/26, in an educated sample, no education adjustment was used. One study (N=85) in Thailand [53], suggested a cut off of 24/25 in a poorly educated sample.…”

The MoCA is widely used to screen for mild cognitive impairment. While there are many available versions, the cross cultural validity of the assessment has not been explored sufficiently.We aimed to interrogate the validity of the MoCA in a cross-cultural context: in differentiating mild cognitive impairment (MCI) from normal controls (NC); and identifying cut-offs and adjustments for age and education where possible. This review sourced a wide range of studies including case-control studies. In addition, we report findings for differentiating dementias from NC and MCI from dementias, however, these were not considered to be an appropriate use of the MoCA.The subject of the review assumes heterogeneity and therefore meta-analysis/es was not conducted. Quality ratings, forest plots of validated studies (sensitivity and specificity) with covariates (suggested cut-offs, age, education and country) and summary received operating characteristic curve (sROC) are presented.The results showed a wide range in suggested cutoffs for MCI cross culturally, with variability in levels of sensitivity and specificity ranging from low to high. Poor methodological rigour appears to have affected reported accuracy and validity of the MoCA.The review highlights the necessity for cross cultural considerations when using the MoCA, and recognizing it as a screen and not a diagnostic tool. Appropriate cutoffs and point adjustments for education are suggested.2

“…6 It was validated to detect cognitive impairment in different clinical populations including those with Parkinson's disease, brain metastases and stroke, and had established cross-cultural performance in detecting MCI and dementia. [7][8][9][10][11][12] However, educational adjustment and cutoffs varied. In a Korean study, a cutoff score of 22/23 yielded a sensitivity of 89% and specificity of 84% for screening MCI.…”

A validation study of the Hong Kong version of Montreal Cognitive Assessment (HK-MoCA) in Chinese older adults in Hong Kong

Design: Cross-sectional study.Setting: Cognition clinic and memory clinic of a public hospital in Hong Kong.Participants: A total of 272 participants (dementia, n=130; mild cognitive impairment, n=93; normal controls, n=49) aged 60 years or above were assessed using HK-MoCA. The HK-MoCA scores were validated against expert diagnosis according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed) criteria for dementia and Petersen's criteria for mild cognitive impairment. Statistical analysis was performed using receiver operating characteristic curve and regression analyses. Additionally, comparison was made with the Cantonese version of Mini-Mental State Examination and Global Deterioration Scale. Results:The optimal cutoff score for the HK-MoCA to differentiate cognitive impaired persons (mild cognitive impairment and dementia) from normal controls was 21/22 after adjustment of education level, giving a sensitivity of 0.928, specificity of 0.735, and area under the curve of 0.920. Moreover, the cutoff to detect mild cognitive impairment was 21/22 with a sensitivity of 0.828, specificity of 0. • It is a reasonably good screening tool for mild cognitive impairment with comparable efficacy with the Cantonese version of Mini-Mental State Examination (MMSE). Implications for clinical practice or policy • HK-MoCA is brief and feasible to conduct in the clinical setting, and can be completed in less than 15 minutes.• HK-MoCA provides an attractive screening instrument in place of MMSE which has ceiling effect and needs to be purchased due to copyright issues.

“…The Japanese MMSE used in this study [44], score less than 23 was classified as cognitive impairment. In a current study, MMSE had an excellent sensitivity (97%) and good specificity (89%) for screening AD at the cut-off point of 28/29, but it had poor specificity (58%) for screening MCI at the cut-off point of 29/30) [45]. In Malaysia, cut-off score was 22 with sensitivity 88.5% and specificity 75.3% [17].…”

Background: The mini-mental state examination (MMSE) was adapted by individual countries according to their languages and cultures, though it has not been systematically compared. The objective of this study was to compare the linguistic and cultural variations of the MMSE used in various Asian countries. With this, we can analyze the strengths and weaknesses of the MMSE and consider using a common version in future international clinical studies in Asia. Methods: We collected the MMSEs used in 11 Asian nations. After translating those into English, we compared them to understand the differences in the questionnaires with regard to cultural aspects. Results: Many items may be applicable or comparable with a little modification, for Asian countries. However, attention and calculation and repetition may be incomparable. There were some differences in the contents and the ways to administer. Conclusions: The lack of consideration of the cultural differences and their influences on the interpretation of the same cognitive test makes cross-cultural studies difficult. Some items of MMSE tasks need readjusting for, if any, multi-national studies. This study might serve as a first step in the development of a standardized cross-cultural cognitive instrument, especially in Asia.
