随着社会迅速老龄化，对抗与年龄相关的正常认知功能下降变得越来越重要。越来越多的证据表明，认知训练计划可能有可能抵消这种下降。越来越多的研究表明冥想对年轻人和中年人的认知有积极影响，冥想可能能够抵消与年龄相关的正常认知衰退，甚至增强老年人的认知功能。在本文中，我们回顾了调查冥想对与年龄相关的认知衰退影响的研究。我们检索了 Web of Science（1900 年至今）、PsycINFO（1597 年至今）、MEDLINE（1950 年至今）和 CABI（1910 年至今），以确定调查冥想对认知和衰老背景下认知衰退的影响的原始研究。该评价纳入了十二项研究，其中六项是随机对照试验。研究涉及多种冥想技巧，并报告了对注意力、记忆力、执行功能、处理速度和一般认知的初步积极影响。然而，大多数研究存在较高的偏倚风险和较小的样本量。报告的辍学率较低，而遵守率较高。我们的结论是，对老年人进行冥想干预是可行的，初步证据表明冥想可以抵消与年龄相关的认知衰退。
With a rapidly aging society it becomes increasingly important to counter normal age-related decline in cognitive functioning. Growing evidence suggests that cognitive training programs may have the potential to counteract this decline. On the basis of a growing body of research that shows that meditation has positive effects on cognition in younger and middle-aged adults, meditation may be able to offset normal age-related cognitive decline or even enhance cognitive function in older adults. In this paper, we review studies investigating the effects of meditation on age-related cognitive decline. We searched the Web of Science (1900 to present), PsycINFO (1597 to present), MEDLINE (1950 to present), and CABI (1910 to present) to identify original studies investigating the effects of meditation on cognition and cognitive decline in the context of aging. Twelve studies were included in the review, six of which were randomized controlled trials. Studies involved a wide variety of meditation techniques and reported preliminary positive effects on attention, memory, executive function, processing speed, and general cognition. However, most studies had a high risk of bias and small sample sizes. Reported dropout rates were low and compliance rates high. We conclude that meditation interventions for older adults are feasible, and preliminary evidence suggests that meditation can offset age-related cognitive decline.
