OBJECTIVES
To verify the diagnostic accuracy of the Brazilian version of the Mattis Dementia Rating Scale (DRS) in the diagnosis of patients with mild dementia in Alzheimer's disease (AD); to verify the interference of the variables age and schooling on the performance of the DRS.
METHOD
The DRS was administered to 41 patients with mild AD and to 60 controls. In order to analyze the effects of age and schooling on the performance of the tests, patients and controls were separated into three age groups and three levels of schooling.
RESULTS
The cutoff score of 122 showed a sensitivity of 91.7 % and specificity of 87.8 %. Age and schooling interfered in the DRS total score and in the scores of its subscales.
CONCLUSION
The DRS showed good diagnostic accuracy in the discrimination of patients with mild AD from the control individuals. In the sample examined, the effects of schooling were more marked than age.
目的
验证巴西版马蒂斯痴呆评定量表（DRS）在阿尔茨海默病（AD）轻度痴呆患者诊断中的诊断准确性；验证年龄和受教育程度变量对DRS表现的影响。
方法
对41例轻度AD患者和60例对照者进行DRS测试。为分析年龄和受教育程度对测试表现的影响，将患者和对照者分为三个年龄组和三个受教育程度水平。
结果
临界值122的敏感性为91.7%，特异性为87.8%。年龄和受教育程度对DRS总分及其子量表得分有影响。
结论
DRS在区分轻度AD患者与对照个体方面显示出良好的诊断准确性。在所检查的样本中，受教育程度的影响比年龄更明显。
