“…Thus, the CNTB, developed to minimize the influence of culture, language, and educational level, 13 may represent a valid alternative to other neuropsychological batteries. 14 Our group has recently validated a Brazilian Portuguese version of the Rowland Universal Dementia Assessment Scale (RUDAS), 15 showing that it is accurate and valid to assess neuropsychological performance regardless of the person's educational level. However, the availability of methods for accurate assessment of multidomain cognitive functioning in illiterate and older adults with low levels of education is becoming increasingly important in Brazil.…”

Objective: To translate, establish the diagnostic accuracy, and standardize the Brazilian Portuguese version of the European Cross-Cultural Neuropsychological Test Battery (CNTB) considering schooling level. Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the CNTB. A total of 135 subjects aged over 60 years-65 cognitively healthy (mean 72.83, SD = 7.71; mean education 9.42, SD = 7.69; illiterate = 25.8%) and 70 with Alzheimer's disease (AD) (mean 78.87, SD = 7.09; mean education 7.62, SD = 5.13; illiterate = 10%)-completed an interview and were screened for depression. The receiver operating characteristic (ROC) analysis was used to verify the accuracy of each CNTB test to separate AD from healthy controls in participants with low levels of education (p 4 years of schooling) and high levels of education (X 8 years of schooling). The optimal cutoff score was determined for each test. Results: The Recall of Pictures Test (RPT)-delayed recall and the Enhanced Cued Recall (ECR) had the highest power to separate AD from controls. The tests with the least impact from schooling were the Rowland Universal Dementia Assessment Scale (RUDAS), supermarket fluency, RPT naming, delayed recall and recognition, and ECR. Conclusions: The Brazilian Portuguese version of the CNTB was well comprehended by the participants. The cognitive tests that best discriminated patients with AD from controls in lower and higher schooling participants were RPT delayed recall and ECR, both of which evaluate memory.

“…The use of the former scale may improve the cognitive screening of older adults in different cultures, as it was easily comprehended by participants of different educational levels after direct translation into Brazilian Portuguese. Also, it was not significantly influenced by educational level 22 .…”

“…Most of the studies found in this review compared the diagnostic accuracy of new instruments, such as the Rowland Universal Dementia Assessment Scale, or combinations of traditional screening instruments, with the accuracy of the MMSE. These studies have indicated that longer instruments, such as the Mattis Dementia Rating Scale and the Cambridge Cognition Examination, and shorter ones, such as the Cognitive Abilities Screening Instrument-Short Form, may be just as accurate in detecting AD in populations with little educat ion 3,20,21,22,25,36,37,38,39,40,41,42,43,44 . When combined with the MMSE, these instruments may increase the diagnostic accuracy 3 .…”

The ideal cut-off score of the Brazilian version coincided with the one proposed for the original instrument (< 23 points) 27 and the sensitivity and specificity were similar to those observed for the MMSE.…”

Cognitive screening instruments are influenced by education and/or culture. In Brazil, as illiteracy and low education rates are high, it is necessary to identify the screening tools with the highest diagnostic accuracy for Alzheimer's disease (AD). Objective: To identify the cognitive screening instruments applied in the Brazilian population with greater accuracy, to detect AD in individuals with a low educational level or who are illiterate. Methods: Systematic search in SciELO, PubMed and LILACS databases of studies that used cognitive screening tests to detect AD in older Brazilian adults with low or no education. Results: We found 328 articles and nine met the inclusion criteria. The identified instruments showed adequate or high diagnostic accuracy. Conclusion: For valid cognitive screening it is important to consider sociocultural and educational factors in the interpretation of results. The construction of specific instruments for the low educated or illiterate elderly should better reflect the difficulties of the Brazilian elderly in different regions of the country.

Diagnosing dementia in lower educated older persons: validation of a Brazilian Portuguese version of the Rowland Universal Dementia Assessment Scale (RUDAS)

Abstract: The RUDAS-BR is as accurate as the MMSE in screening for dementia. RUDAS-BR scores were not influenced by education. The RUDAS-BR may improve the cognitive assessment of older persons who are illiterate or of lower educational attainment.
