我们对曼哈顿北部随机选择的说英语的非西班牙裔美国人和白人老年人的社区样本进行了神经心理测试。AU参与者被神经科医生诊断为非痴呆，其评估独立于神经心理学测试分数。非裔美国老年人在语言和非语言学习和记忆、抽象推理、语言和视觉空间技能方面的得分明显低于白人。在使用分层随机抽样技术匹配各组受教育年限后，许多差异变得不显著；然而，在图形记忆、语言抽象、类别流畅性和视觉空间技能方面，种族间的显著差异仍然存在。教育匹配的非裔美国人和白人在测试成绩上的差异不能用职业成就或高血压和糖尿病等病史来解释。这些发现强调了在评估不同种族的老年人患痴呆症时，使用文化上适当的规范的重要性。
We examined the neuropsychological test performance of a randomly selected community sample of English-speaking non-Hispanic African American and white elders in northern Manhattan. AU participants were diagnosed as nondemented by a neurologist, whose assessment was made independent of neuropsychological test scores. African American elders obtained significantly lower scores on measures of verbal and nonverbal learning and memory, abstract reasoning, language, and visuospatial skill than whites. After using a stratified random sampling technique to match groups on years of education, many of the discrepancies became nonsignificant; however, significant ethnic group differences on measures of figure memory, verbal abstraction, category fluency, and visuospatial skill remained. Discrepancies in test performance of education-matched African Americans and whites could not be accounted for by occupational attainment or history of medical conditions such as hypertension and diabetes. These findings emphasize the importance of using culturally appropriate norms when evaluating ethnically diverse elderly for dementia.
