背景
在当代精神病评估和诊断中，对时间流逝的估计几乎没有受到关注。关于老年痴呆症患者，特别是老年痴呆症患者估计时间流逝的能力存在分歧，并且缺乏关于处于认知障碍早期阶段的老年人估计时间流逝的能力的数据。
目的
我们研究了一个假设，即轻度痴呆患者的表现比没有认知障碍的人差，而轻度认知障碍（MCI）患者在准确估计时间流逝的能力方面处于中间位置。另一个目的是研究人口统计学和临床（认知，功能，精神）预测自我估计的性能时间与实际的性能时间。
方法
在一个全面的老年精神病评估的背景下，建立了三个性能时间的措施：实际的性能时间，主观估计的性能时间，性能时间估计的准确性。
结果
对102名疑似MCI的连续患者进行了评估。最终认知诊断为：痴呆49例（48%），MCI 36例（35%），无认知障碍（NCI）17例（17%）。而有显着的组间差异（痴呆，MCI，NCI）的所有认知功能的措施和功能障碍，有三个时间措施没有显着的组间差异。除年龄外，估计的执行时间与任何其他人口统计学和临床变量无关。
结论
与无认知障碍的参与者相比，痴呆组或MCI组的自我估计表现时间与实际表现时间没有受损。
BACKGROUND
Estimation of the passage of time has received marginal attention in contemporaneous psychiatric assessment and diagnosis. There is disagreement regarding the ability of older adults with dementia, particularly of the Alzheimers type, to estimate time passage, and there is lack of data concerning the ability of older adults in the early stages of cognitive impairment to estimate the passage of time.
OBJECTIVE
We investigated the hypothesis that individuals with mild dementia perform worse compared to those with no cognitive impairment, and that those with mild cognitive impairment (MCI) assume an intermediate position in terms of their ability to accurately estimate time passage. Another objective was to study demographic and clinical (cognitive, functional, psychiatric) predictors of self-estimation of performance time versus actual performance time.
METHOD
In the context of a comprehensive psychogeriatric evaluation, three performance time measures were established: actual performance time, subjective estimation of performance time, and accuracy of estimation of performance time.
RESULTS
102 consecutive persons with suspected MCI were assessed. Final cognitive diagnoses were: dementia 49 (48%), MCI 36 (35%), no cognitive impairment (NCI) 17 (17%). Whereas there were significant group differences (dementia, MCI, NCI) on all cognitive measures and on functional impairment, there were no significant group differences on the three time measures. With the exception of age, estimation of performance time was not associated with any of the other demographic and clinical variables.
CONCLUSION
Self-estimation of performance time versus actual performance time was not found impaired either in the dementia group or in the MCI group when compared to participants without cognitive impairment.
