摘要

前瞻记忆(PM)是一种记住在未来时刻执行计划行动的能力,它对从发育到成年后期的独立自主的生活方式至关重要。情景记忆和执行功能缺陷与PM有关,是轻度认知障碍(MCI)和阿尔茨海默病(AD)的特征。考虑到老年人的数量在未来几十年将急剧增加,了解健康老年人和不同程度认知衰退患者的PM如何下降是非常有意义的。本荟萃分析包括46项研究,调查AD患者(17项研究)和MCI患者(24项研究)的PM表现;5项研究在同一篇文章中纳入了这两种临床情况。这46项研究共提供了63个独立样本和129个效应量,来自4668名参与者(2115名患者和2553名对照)。与之前的文献综述不同,我们的研究样本更大,更新的结果证实,与MCI和对照组相比,AD患者的PM能力较低,尽管我们没有观察到患者基于事件和基于时间的PM之间的结论性差异。令人惊讶的是,MCI和AD患者表现出的PM缺陷逐年减少,与此同时,发表偏倚的证据减少,每个任务的观察数量增加。我们建议使用更可靠的研究设计作为PM损伤减少的一个合理解释。

Time-Based and Event-Based Prospective Memory in Mild Cognitive Impairment and Alzheimer's Disease Patients: A Systematic Review and Meta-analysis.

Time-Based and Event-Based Prospective Memory in Mild Cognitive Impairment and Alzheimer's Disease Patients: A Systematic Review and Meta-analysis.

Prospective memory (PM) is the ability to remember to perform planned actions in a future moment and it is of fundamental importance for an independent and autonomous lifestyle from development to late adulthood. Deficits in episodic memory and executive functions, which are involved in PM are characteristic features of mild cognitive impairment (MCI) and Alzheimer's disease (AD). Considering that the number of older adults is drastically increasing over the next decades, it is of great interest to understand how PM decline in healthy older adults and patients with different degree of cognitive decline. The present meta-analysis included 46 studies investigating PM performance in AD patients (17 studies) and people with MCI (24 studies); 5 studies included both clinical conditions in the same article. The 46 studies contributed a total of 63 independent samples and 129 effect sizes from 4668 participants (2115 patients and 2553 controls). Unlike previous reviews of the literature, our results with a larger and updated sample of studies confirmed lower PM abilities in AD compared to MCI and controls, although we did not observe conclusive differences between event-based and time-based PM in patients. Surprisingly, PM deficits shown by MCI and AD patients have decreased across years, in parallel to a reduction of the evidence of publication bias and an increase in the number of observations per task. We propose the use of more reliable research designs as one plausible explanation for the reduction of PM impairments.

期刊介绍: Neuropsychology Review is a quarterly, refereed publication devoted to integrative review papers on substantive content areas in neuropsychology, with particular focus on populations with endogenous or acquired conditions affecting brain and function and on translational research providing a mechanistic understanding of clinical problems. Publication of new data is not the purview of the journal. Articles are written by international specialists in the field, discussing such complex issues as distinctive functional features of central nervous system disease and injury; challenges in early diagnosis; the impact of genes and environment on function; risk factors for functional impairment; treatment efficacy of neuropsychological rehabilitation; the role of neuroimaging, neuroelectrophysiology, and other neurometric modalities in explicating function; clinical trial design; neuropsychological function and its substrates characteristic of normal development and aging; and neuropsychological dysfunction and its substrates in neurological, psychiatric, and medical conditions. The journal''s broad perspective is supported by an outstanding, multidisciplinary editorial review board guided by the aim to provide students and professionals, clinicians and researchers with scholarly articles that critically and objectively summarize and synthesize the strengths and weaknesses in the literature and propose novel hypotheses, methods of analysis, and links to other fields.
