目前的研究为70岁及以上的个体提供了几项神经心理学测试的纵向稳健规范。我们比较了基线时无痴呆的三组患者的基线神经心理学测试表现：至少两次随访后评估无痴呆的稳健规范样本，在随访期间新发痴呆的事件痴呆样本和失访（LTF）样本。ANCOVA显示，与痴呆和LTF样本相比，稳健样本在所有神经心理学测试中表现更好。这些发现支持了这样一种观点，即向痴呆症过渡的个体可能会降低平均值，增加变异性，从而低估正常衰老的认知表现。我们认为，纵向稳健规范可能有助于减轻横截面规范样本固有的局限性。(C)2008年美国国家神经心理学学会。由爱思唯尔有限公司出版。保留所有权利。
The current study provided longitudinal robust norms for individuals age 70 years and older for several neuropsychological tests. We compared baseline neuropsychological test performance in three groups free of dementia at baseline: a robust normative sample free of dementia for at least two post-follow-up assessments, an incident dementia sample which developed new onset dementia during the follow-up and a lost to follow-up (LTF) sample. ANCOVAs showed that the robust sample performed better on all neuropsychological tests compared to the incident dementia and LTF samples. These findings support the argument that individuals in transition to developing dementia may reduce the mean, increase the variability and therefore underestimate cognitive performance in normal aging. We suggest that longitudinal robust norms may help mitigate the limitations inherent in cross-sectional normative samples. (C) 2008 National Academy of Neuropsychology. Published by Elsevier Ltd.
