Mindfulness-based programs (MBPs) show a small but significant benefit for cognitive performance, particularly for executive function and working memory, according to a meta-analysis of 56 randomized controlled trials involving 2,931 adults. The overall effect favoring MBPs over comparators was small (g = 0.15). Benefits were strongest for non-clinical samples and adults over 60, and when MBPs were compared to inactive controls rather than active ones. No significant effects were found for other cognitive domains. Most studies had unclear risk of bias, and some statistical results were unreliable. The findings partially support the idea that mindfulness practice can enhance certain cognitive abilities.

An 18-month randomized trial of meditation training versus non-native language training or no intervention in cognitively unimpaired adults aged 65 and older found no significant changes in brain volume or perfusion of the anterior cingulate cortex or insula from meditation. Meditation did produce superior improvements in a composite score of attention regulation, socioemotional capacities, and self-knowledge compared with language training. The findings confirm the feasibility of both meditation and language training in older adults, with high adherence and low dropout, but the positive behavioral effects of meditation were not accompanied by measurable changes in the targeted brain structures.

Expert meditators show preserved brain structure and better psycho-affective health compared to meditation-naive older adults, suggesting that long-term meditation practice may protect against age-related decline. The study examined older expert meditators and older meditation-naive participants, finding that the expert group had greater brain preservation and more favorable psycho-affective profiles. These results indicate that meditation could be a protective factor for brain and mental health in aging.

Older adults who spent more time practicing meditation perceived greater benefits from an 18-month meditation program. The study involved 90 healthy adults aged 65-84 years who were randomly assigned to either meditation training or a non-native language training. Higher levels of formal practice were associated with higher combined ratings of self- and teacher-perceived responsiveness across measures of connection, emotions, and meta-awareness during sessions and in daily life. Global responsiveness scores were not correlated with actual changes in well-being. The findings suggest that engagement, rather than baseline characteristics like personality or expectancy, predicts perceived response to meditation training.

Expert meditators in older age reported less external distraction and performed better on memory tasks compared to non-meditators, while no differences were found in attention, executive function, or global cognitive scores. These cross-sectional findings from 135 non-meditators and 27 expert meditators suggest that prolonged meditation practice may help preserve memory and manage distractions, two cognitive capacities important for healthy aging.

An 18-month meditation training in healthy older adults altered resting-state brain dynamics. Participants who meditated showed more frequent transitions between different brain connectivity states and spent less time in a weakly connected state and more time in a strongly connected state, patterns associated with lower and higher dementia risk, respectively. However, only the increase in transitions was significantly different from a non-native language training group. The small effect sizes and lack of group differences for time spent in states limit the conclusions.
