New review led by UCL researchers finds that mindfulness training can yield modest cognitive benefits, especially for people over 60.
A systematic review and meta-analysis published in Neuropsychology Review examined randomized studies of mindfulness-based programs (MBPs) and their effects on objective cognitive outcomes. While mindfulness is most often promoted for mental health and well-being, the analysis indicates it may also support certain aspects of brain health.
Tim Whitfield, the study’s lead author and a PhD student at UCL Psychiatry, noted: “The mental health benefits of mindfulness-based programmes are well documented. Our review suggests there is also a small but measurable benefit to cognition, most clearly in older adults.”
The research team screened the literature and identified 45 studies that met strict inclusion criteria for synthesis, representing 2,238 participants. Included trials involved facilitator-led, group-based mindfulness interventions delivered across at least four sessions; intensive retreat-style interventions were excluded to maintain a consistent study set.
Most trials featured certified instructors guiding participants through practices such as sitting meditation, mindful movement, and body-scan exercises. Programs typically ran weekly for six to 12 weeks and encouraged participants to continue practicing outside of class sessions.
Across all analyzed studies, mindfulness training showed a small but statistically significant positive effect on cognition. When the authors examined subgroups, the benefit was more pronounced among adults aged 60 and older; in contrast, studies of younger adults did not show a significant cognitive advantage.
Whitfield explained the age-related finding: “Executive function commonly declines with age. The fact that benefits appeared strongest in people over 60 suggests mindfulness may help preserve or partially restore executive functioning in late adulthood. It may be easier to regain previously attained cognitive abilities than to push them beyond developmental peaks.”
When the researchers looked at specific cognitive domains, improvements were concentrated in executive function, and within that domain, the strongest evidence pointed to working memory gains. Other cognitive areas did not show reliable improvements attributable to MBPs.
The review also compared mindfulness to different types of control conditions. Mindfulness programs outperformed inactive comparators (for example, waitlists or usual care), but did not show significant advantages over active control interventions such as brain training, relaxation, or other structured health and educational programs. This pattern means the observed cognitive gains could in part reflect nonspecific factors such as expectations of benefit or social engagement associated with group programs.
The authors emphasize the need for further research to determine which specific features of mindfulness training are most likely to produce cognitive benefits. Questions remain about whether longer-term interventions, different delivery formats, or more intensive retreat settings might generate larger or more durable cognitive effects.
Senior author Dr Natalie Marchant (UCL Psychiatry) said: “Mindfulness-based programmes are established tools for promoting mental health, and our review suggests they may also contribute to preserving cognitive abilities with age. Because mindfulness practices differ substantially from the tasks used in cognitive testing, it is notable that training transfers at all to objective cognitive measures. Although the detected benefits were modest and largely restricted to executive function, some types of MBPs might yield larger improvements if optimized.”

Abstract
The Effect of Mindfulness-based Programs on Cognitive Function in Adults: A Systematic Review and Meta-analysis
Mindfulness-based programs (MBPs) are increasingly used to improve mental health, and interest in their potential cognitive effects is growing. This study is the first meta-analysis to pool objective cognitive outcomes across randomized MBP trials in adults.
Seven databases were searched through January 2020. Fifty-six unique studies (n = 2,931) were identified, of which 45 studies (n = 2,238) met criteria for meta-analytic synthesis using robust variance estimation. Meta-regression and subgroup analyses examined potential moderators.
When pooling data across cognitive domains, MBPs showed a small overall advantage over comparators (g = 0.15; 95% CI [0.05, 0.24]). Subgroup analyses indicated benefits were specific to executive function (g = 0.15; [0.02, 0.27]) and, particularly, working memory (g = 0.23; [0.11, 0.36]). Significant effects were observed for non-clinical samples and for adults aged over 60.
Across studies, MBPs outperformed inactive comparators but did not outperform active comparators. Limitations include unclear risk-of-bias in many trials and some statistical constraints that affect interpretation of p-values.
Overall, findings partially support the idea that mindfulness training can transfer to measurable cognitive improvements, particularly for executive processes in older adults. This review was registered with PROSPERO [CRD42018100904].
