Two methods of estimating premorbid WAIS-R intelligence were compared in matched samples of normal and AD persons. The NART and Barona 1984 demographic equations accurately predicted the IQs of the normal group and overestimated the IQs of the AD subjects. When the AD group was divided into mild and moderately impaired subgroups, the more severely demented subjects displayed lower WAIS-R IQs and NART estimated IQs, revealing that NART performance is sensitive to dementia severity. However, the NART estimated IQs for the mild and moderately impaired AD subgroups were larger than the WAIS-R IQs, suggesting that while the NART is sensitive to dementia severity, it may still provide relevant clinical information.
在正常人和阿尔茨海默病（AD）患者的匹配样本中，对两种估计病前韦氏成人智力量表修订版（WAIS-R）智力的方法进行了比较。国家成人阅读测验（NART）和巴罗纳1984年的人口统计学方程准确预测了正常组的智商，但高估了AD患者的智商。当将AD组分为轻度和中度受损亚组时，痴呆程度越严重的受试者韦氏成人智力量表修订版智商和国家成人阅读测验估计智商越低，这表明国家成人阅读测验表现对痴呆严重程度敏感。然而，轻度和中度受损AD亚组的国家成人阅读测验估计智商高于韦氏成人智力量表修订版智商，这表明虽然国家成人阅读测验对痴呆严重程度敏感，但它仍可能提供相关临床信息。
