Two methods were used to estimate premorbid IQ in a sample of 68 patients with mild dementia: (1) the National Adult Reading Test (NART), a present ability measure, and (2) an age, sex, race, education and occupation regression formula, a demographically based estimate (DIQ). The dementia sample consisted of probable Alzheimer's disease, multi-infarct dementia and a mixture of the two. The sample was divided into three levels of language disturbances (no language disturbance, naming or fluency disturbance, or both naming and fluency disturbance) based upon performance on the Visual Naming test and the Controlled Oral Word Association test. The NART IQ estimates in patients with one or more language disturbances were significantly lower than those in patients without language disturbances despite equivalent DIQ and Mini-Mental Status exam performance. The results suggest that the applicability of the NART to dementia patients with prominent language disturbances is limited.
采用两种方法对68例轻度痴呆患者的病前智商进行评估：（1）国家成人阅读测验（NART），一种当前能力测量方法；（2）年龄、性别、种族、教育程度和职业回归公式，一种基于人口统计学的估计值（病前智商估计值）。痴呆样本包括可能的阿尔茨海默病、多发梗死性痴呆以及两者的混合类型。根据视觉命名测验和受控口语联想测验的表现，将样本分为三个语言障碍水平（无语言障碍、命名或流畅性障碍、或命名和流畅性均有障碍）。尽管病前智商估计值和简易精神状态检查表现相当，但有一项或多项语言障碍的患者的NART智商估计值显著低于无语言障碍的患者。结果表明，NART对有明显语言障碍的痴呆患者的适用性有限。
