This study explores different episodic memory domains, namely object, temporal and spatial memory, affected in patients with a clinical diagnosis of single domain amnestic mild cognitive impairment (aMCI). 15 aMCI patients and 25 healthy controls were recruited and tested. Object, spatial, and temporal memory were tested using computerized tasks and again in interactive, real-world tasks. Controls outperformed patients on the object computerized task and showed a trend toward significance for the computerized spatial and temporal tasks, but there was no difference in spatial and temporal memory when using the interactive tasks, indicating the employment of compensatory mechanisms in patients to overcome some of the memory impairments associated with aMCI. These findings highlight that aMCI patients might delay seeking help due to compensatory mechanisms which mask their deficits in real-world situations.
本研究探讨了不同的情景记忆领域,即物体、时间和空间记忆,在临床诊断为单一领域遗忘型轻度认知障碍(aMCI)的患者中受到的影响。招募了 15 名 aMCI 患者和 25 名健康对照者并对其进行了测试。使用计算机化任务和交互式真实世界任务再次测试了物体、空间和时间记忆。在物体计算机化任务中,对照组的表现优于患者,并且在计算机化的空间和时间任务中表现出显著趋势,但在使用交互式任务时,空间和时间记忆没有差异,这表明患者在使用补偿机制来克服与 aMCI 相关的一些记忆障碍。这些发现强调,由于补偿机制掩盖了患者在现实生活情境中的缺陷,因此他们可能会延迟寻求帮助。
