The inclusion of individuals with incipient dementia in normative data contaminates the distinction between normal and pathological aging. Conventional and Robust (excluding persons with incipient dementia) norms were created using data from the Canadian Study of Health and Aging (CSHA). Robust norms were not significantly better at distinguishing between normal and pathological aging. Norms reflecting the relationship between age and the prevalence of dementia revealed a probability of dementia of less than 35%. The results of the norming procedure serve to illustrate the validity of our current measures and methods for identifying cognitive impairment. CSHA Conventional norms are adequate for the identification of cognitive impairment.
将早期痴呆症患者纳入正常数据会模糊正常衰老与病理性衰老之间的区别。常规规范和稳健规范（排除早期痴呆症患者）是根据加拿大健康与老龄化研究（CSHA）的数据制定的。在区分正常衰老和病理性衰老方面，稳健规范并没有显著更好的表现。反映年龄与痴呆症患病率之间关系的规范显示，痴呆症的概率低于35%。规范制定程序的结果有助于说明我们目前识别认知障碍的测量方法和手段的有效性。CSHA常规规范足以用于识别认知障碍。
