正念训练对老年认知功能干预的系统综述

A systematic review of cognitive intervention studies of mindfulness training in older adults

关于正念训练对老年认知功能的干预效果,以往的研究显示出不一致的结果,目前尚缺乏相关的系统性文献综述。按照训练方法和老年人群的分类标准,本文将纳入的文献中的认知功能干预结果进行梳理、归纳和总结。结果表明正念训练的干预效果与认知衰退程度和训练方法有关:标准化和非标准化的正念训练均能提高正常老年和主观认知下降老年的认知功能;但随着干预对象的认知衰退程度的加重,训练效果逐渐降低,在轻度认知障碍患者中的效果不一致,在痴呆患者中效果均不显著。

Mindfulness training has shown beneficial effects on cognitive functions in older adults.However,the studies on this topic have used different methods and populations,and their results were inconsistent No systematic review has synthesized and evaluated these findings.This review aims to address this gap by categorizing the studies based on the training methods and cohorts of older adults,and summarizing the effects of mindfulness training on cognitive functioa The review finds that mindfulness training had different effects depending on the level of cognitive decline and the training method Both standardized and unstandardized training methods improved cognitive performance in older adults with normal or subjective cognitive decline.However,the effect of mindfulness training diminished as cognitive decline worsened,being inconsistent in mild cognitive impairment and non-significant in dementia.The review also discusses the possible mechanisms and suggested directions for future research.
