BACKGROUND/OBJECTIVES Mind‐body exercise has positive effects on cognitive performance, according to clinical observation and experts’ recommendations. However, its potential benefits for the cognitive function of aging adults are uncertain and still lack systematic estimations. Therefore, we conducted a systematic review and meta‐analysis to evaluate the overall efficacy and effectiveness of mind‐body exercises for cognitive performance in aging individuals with or without cognitive impairment. DESIGN A systematic review and meta‐analysis. SETTING AND PARTICIPANTS We searched related trials through June 2018 from four databases: Medline, Embase, PsycINFO (all via Ovid), and the Cochrane Library/Central Register of Controlled Trials. MEASUREMENTS Methodological quality was assessed using the Cochrane Risk of Bias Tool. A meta‐analysis of comparative effects was performed using Review Manager v.5.3 software, and publication bias was examined using Egger's test. RESULTS A total of 32 randomized controlled trials with 3624 participants were ultimately included in this meta‐analysis. The results revealed that mind‐body exercises as a whole had benefits in improving global cognition compared with that of the control group (mean difference [MD] = 0.92; 95% confidence interval [CI] = 0.33‐1.51; p = .002) and were more effective than control interventions in promoting cognitive flexibility (MD = −8.80; 95% CI = −15.22 to −2.38; p = .007), working memory (MD = 0.32; 95% CI = 0.01‐0.64; p = .05), verbal fluency (standardized mean difference [SMD] = 0.27; 95% CI = 0.09‐0.45; p = .003), and learning (SMD = 0.24; 95% CI = 0.10‐0.39; p = .001) on cognitively intact or impaired older adults. In dose‐subgroup analysis, only moderate exercise intensity (60‐120 min per week) significantly increased global cognition scores compared with those of the control group (MD = 1.15; 95% CI = 0.34‐1.97; p = .006). CONCLUSION Mind‐body exercises, especially tai chi and dance mind‐body exercise, are beneficial for improving global cognition, cognitive flexibility, working memory, verbal fluency, and learning in cognitively intact or impaired older adults. Moderate intensity is recommended as the optimal dose for older adults. J Am Geriatr Soc 67:749–758, 2019.

IntroductionThe impacts of education on cognitive decline across different neighborhood environments (NEs) have rarely been studied.MethodsWe investigated and compared the associations between educational attainment and cognitive decline using data of 1286 participants from the Taizhou Imaging Study (TIS) and the Shanghai Aging Study (SAS).ResultsCompared with low‐educated participants, in TIS with disadvantaged NE, high‐educated participants manifested a significantly slower decline in global cognition (.062 Z score per year, P < .001), memory (.054 Z score per year, P < .05), and attention (.065 Z score per year, P < .01), whereas in SAS with advanced NE, highly educated individuals exhibited a slower decline only in attention (.028 Z score per year, P < .05).DiscussionWe observed the additive effect of educational attainment and NE on cognitive decline in older adults. Education is especially important for maintaining cognitive health in a disadvantaged environment.
