Objective: Mind-body exercises such as yoga and meditation have been linked to positive health outcomes. Several studies have examined the effects of mind-body exercises on cognition in healthy older adults; however, findings have been mixed. This meta-analysis aims to examine the literature and determine the effect of mind-body exercises on cognition. Method: A literature search of articles available prior to January 2015 was performed using the PubMed database. Articles were selected on the basis of the following criteria: (1) sample consisted of healthy older adults; (2) cognitive performance was measured following a mind-body intervention; (3) studies were independent of each other (4) statistics reported included a mean and standard deviation; and (5) study design was a between-subjects design. Only three studies met criteria to be included in the present analysis. Results: Because several cognitive test variables were nested within each study, a multilevel linear random effects model was used for this meta-analysis. Cohen's d was calculated using the means and standard deviations from 19 cognitive tests. Cognitive tests primarily measured executive functioning. The results revealed a small pooled effect size estimate, d = 0.23, (SE = 0.13, p = 0.08, 95% CI [−0.02, 0.48]. The confidence interval reflects a moderately precise estimate of the population effect. Conclusion: This meta-analysis suggests a small positive effect of mind-body exercises on cognition in older adults. Given the limited research in this area, more experimental investigation should be conducted to determine if mind-body exercises can be an effective strategy in increasing cognitive performance in older adults.
