背景和目标：“储备”的概念已被用来解释个人之间的差异，在他们的能力，以科普或补偿病理。脑储备是指大脑的结构方面，如大脑大小和突触数量。认知储备是通过两种机制优化和最大化表现的能力：大脑网络的招募和/或替代认知策略的补偿。本研究的目的是设计一个工具，全面评估和测量的数量积累的认知储备的个人在其整个生命周期。研究方法：开发了一种使用认知储备指数问卷（CRIq）的新方法，并在588名健康个体的样本中进行了测试，年龄从18岁到102岁，按年龄（年轻人，成年人，老年人）和性别分层。CRIq包括人口统计数据和分为三个部分的项目：教育，工作活动和休闲时间，每个部分都返回一个分项分数。还进行了WAIS词汇测试和TIB。结果：描述了主要的描述特征和一些推论结果。智力与认知储备只有适度的相关性，强调了这两个概念之间的区别。年龄和性别显着影响CRIq分数，而没有效果出现从他们的相互作用。成年人的得分高于年轻人和老年人。结论：这项研究提供了一个新的工具，一个标准化的措施，个人通过他们的生命积累的认知储备。CRIQ在实验研究和临床实践中的潜在用途进行了讨论。（C）2012年，编辑库尔蒂斯
Background and aims: The concept of "reserve" has been used to explain the difference between individuals in their capacity to cope with or compensate for pathology. Brain reserve refers to structural aspects of the brain, such as brain size and synapse count. Cognitive reserve is the ability to optimize and maximize performance through two mechanisms: recruitment of brain networks, and/or compensation by alternative cognitive strategies. The aim of the present research was to devise an instrument for comprehensive assessment and measurement of the quantity of cognitive reserve accumulated by individuals throughout their lifespan. Methods: A new approach using the Cognitive Reserve Index questionnaire (CRIq) was developed and tested in a sample of 588 healthy individuals, from 18 to 102 years old, stratified by age (Young, Adults, Elderly) and gender. The CRIq includes demographic data and items grouped into three sections: education, working activity and leisure time, each of which returns a subscore. The WAIS Vocabulary test and TIB were also administered. Results: The main descriptive features and some inferential results are described. Intelligence was only moderately correlated with cognitive reserve, stressing the distinction between these two concepts. Age and gender significantly affected CRIq scores, whereas no effect emerged from their interaction. Adults showed a higher score than Young and Elderly. Conclusions: This study provides a new instrument for a standardized measure of the cognitive reserve accumulated by individuals through their lifespan. The potential use of the CRIq in both experimental research and clinical practice is discussed. (C)2012, Editrice Kurtis
