中文摘要:
      目的：探讨遗忘性轻度认知障碍（amnestic mild cognitive impairment，aMCI）老年人的资源调配和利 用特征。方法：对40例aMCI患者进行汉语“重复-回忆”言语认知功能测试（repeat-recall test，RRT），计算其 在听觉任务中的资源调配和利用指标，并与认知正常老年人进行比较。利用斯皮尔曼相关分析可能与资源 调配和利用相关的认知项目。结果：在低语境下，当信噪比（signal-to-noise ratio，SNR）为5和－5 dB时，aMCI组的资源调配显著高于认知正常老年人（P＜0.01）；在高语境下，当SNR为0时，aMCI组的资源调配显著 高于认知正常组（P＜0.05）。与对照组相比，aMCI组在所有测试条件下的认知资源利用效率均显著下降（P 均＜0.05）。认知资源调配主要与蒙特利尔认知评估量表（Montreal cognitive assessment，MoCA）中的语言 项目得分呈负相关。资源利用能力除与语言有强烈的正相关性外，也与视空间与执行功能、注意力、定向力 等其他认知维度相关。结论：aMCI患者在言语识别和理解过程中较认知正常人群分配更多认知资源，且对 资源的利用能力更差。
英文摘要:
      To explore the characteristics of resource allocation and utilization in elderly individuals with amnestic mild cognitive impairment (aMCI). Methods: Forty patients with aMCI underwent a Chinese "repeat-recall" speech cognitive function test (RRT), and their resource allocation and utilization indices during auditory tasks were calculated and compared with those of cognitively normal elderly individuals. Spearman correlation analysis was used to identify cognitive items potentially related to resource allocation and utilization. Results: In low-context situations, when the signal-to-noise ratio (SNR) was 5 and -5 dB, resource allocation in the aMCI group was significantly higher than that in the cognitively normal elderly group (P<0.01). In high-context situations, when the SNR was 0 dB, resource allocation in the aMCI group was also significantly higher than that in the control group (P<0.05). Compared with the control group, the aMCI group demonstrated significantly decreased efficiency in cognitive resource utilization under all testing conditions (all P<0.05). Cognitive resource allocation was negatively correlated with scores on the language item of the Montreal Cognitive Assessment (MoCA). Resource utilization ability was strongly positively correlated with language and also correlated with other cognitive dimensions such as visuospatial and executive function, attention, and orientation. Conclusion: Patients with aMCI allocate more cognitive resources during speech recognition and comprehension processes compared to cognitively normal individuals and demonstrate poorer resource utilization abilities.
