The Mini-Mental State Examination was administered to 1865 general-practice patients aged 75 years and over. Even when demented cases were removed from analysis, respondents with relatively little education, together with those in social classes III-manual and below, were significantly more likely to score below the cut-off point used in North American community surveys to denote 'cognitive impairment'. Education and social class influenced scores on all sections within the MMSE with the exception of registration. Sex influenced scores on tests of calculation and spelling backwards but had no effect on total scores. These findings emphasize the importance of investigating low scorers in more detail before making a diagnosis of dementia.
对1865名75岁及以上的全科医疗患者进行了简易精神状态检查表测试。即使在分析中剔除了痴呆病例，受教育程度相对较低的受访者，以及社会阶层为三级体力劳动者及以下的受访者，得分低于北美社区调查中用于表示“认知障碍”的临界值的可能性显著更高。教育程度和社会阶层对简易精神状态检查表所有部分的得分都有影响，但登记部分除外。性别对计算和倒拼测试的得分有影响，但对总分没有影响。这些发现强调了在诊断痴呆症之前更详细地调查低分者的重要性。
