Abstract：
Dementia often manifests with profound alterations in perception, but it is unclear if and to what extent time perception is altered among people living with dementia compared to those experiencing normal aging. Thus, this scoping review aimed to answer the following research questions: (1) What study designs, participants, time intervals, paradigms, tests, and scores have been employed and in which countries were these methods employed to study time perception in dementia? (2) In which ways do time perception differ across individuals living with and without dementia? (3) In which ways do time perception differ across individuals living with different types of dementia? After deduplication, title and abstract screening, and full-text review, a total of 12 studies were included in this scoping review. Findings generally indicated that people living with dementia perceive time differently than people living without dementia, and that some differences across dementia diagnoses may exist, but the body of literature on time perception in dementia was quite limited. Future research should focus on replicating findings while extending the research to look beyond the dementia versus non-dementia dichotomy as differences across dementia diagnoses may exist. Moreover, if people living with dementia (and, in particular, living with different dementia diagnoses) experience time differently from those experiencing normal aging, we need to begin to address these differences in dementia-friendly initiatives to improve well-being for this population.
摘要：
痴呆症通常表现为感知的深刻改变，但目前还不清楚与正常衰老患者相比，痴呆症患者的时间感知是否以及在多大程度上发生了改变。因此，这篇范围界定综述旨在回答以下研究问题：(1)设计了什么研究，参与者,时间间隔,范式，测试,和分数已经被采用，这些方法在哪些国家被用来研究痴呆症的时间知觉？(2)患有和不患有痴呆症的个体的时间知觉在哪些方面有所不同？(3)患有不同类型痴呆症的个体的时间知觉在哪些方面有所不同？重复数据删除后，标题和摘要筛选，和全文回顾，本次范围审查共纳入12项研究.研究结果表明，患有痴呆症的人对时间的感知与没有痴呆症的人不同。痴呆症的诊断可能存在一些差异，但是关于痴呆症时间知觉的文献相当有限。未来的研究应该专注于复制发现，同时将研究扩展到超越痴呆症与非痴呆症二分法，因为痴呆症诊断之间可能存在差异。此外，如果患有痴呆症的人(和，特别是,患有不同的痴呆症诊断）与经历正常衰老的人的时间不同，我们需要开始解决痴呆症友好计划中的这些差异，以改善该人群的福祉。
