ABSTRACT
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 (≤ 4 years of schooling) and high levels of education (≥ 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.
