The Cognitive Reserve (CR) describes the brain's ability to actively cope with neurological damage, enabling the maintenance of premorbid cognitive functioning through compensatory processes. The most common way to estimate CR is through formal education, the intelligence quotient (IQ) and participation in cognitive stimulating activities. In the absence of IQ data, the Irregular Word Reading Test (TeLPI) allows you to estimate the premorbid intelligence.
The comparison of the TeLPI results between two times of assessment (baseline and re-assessment) with an interval time (IT) of 9 years. To analyze of the stability of their results as a valid dimension for the CR estimation.
The TeLPI presented temporal stability of its results between the two evaluation times (IT = 9.07 ± 1.02). The sample, composed by 63 cognitively healthy participants, showed no differences for the estimated Full Scale IQ ((62) = 0.49, = .63), for the Estimated Verbal IQ ((62) = 0.71, = .48) and for the estimated Performance IQ ((62) = 0.64, = .52). Likewise, no differences were found in the number of TeLPI errors at the two assessment times ((62) = -0.61, = .54).
Considering that CR is characterized as being relatively stable, the TeLPI should be included in its assessment, as an indicator with proved stability over a long period of time, on the physiological aging spectrum.
认知储备（CR）描述了大脑积极应对神经损伤的能力，通过代偿过程维持病前认知功能。估计认知储备最常见的方法是通过正规教育、智商（IQ）和参与认知刺激活动。在缺乏智商数据的情况下，不规则单词阅读测试（TeLPI）可用于估计病前智力。
比较间隔时间（IT）为9年的两次评估（基线和重新评估）的TeLPI结果。分析其结果作为认知储备估计有效维度的稳定性。
TeLPI在两次评估时间之间呈现出结果的时间稳定性（IT = 9.07 ± 1.02）。由63名认知健康参与者组成的样本，在估计的全量表智商（（62）= 0.49，p = 0.63）、估计的言语智商（（62）= 0.71，p = 0.48）和估计的操作智商（（62）= 0.64，p = 0.52）方面没有差异。同样，在两次评估时间的TeLPI错误数量上也没有发现差异（（62）= -0.61，p = 0.54）。
鉴于认知储备的特点是相对稳定，TeLPI应纳入其评估中，作为在生理衰老范围内经证实具有长期稳定性的指标。
