The Effect of Mindfulness-based Programs on Cognitive Function in Adults: A Systematic Review and Meta-analysis

Neuropsychology Review August 4, 2021 Tim Whitfield, Thorsten Barnhofer, Rebecca L. Acabchuk et al. 193 citations

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.

Effects of a mindfulness-based intervention and a health self-management programme on psychological well-being in older adults with subjective cognitive decline: Secondary analyses from the SCD-Well randomised clinical trial.

PLoS One January 1, 2023 Marco Schlosser, Harriet Demnitz-King, Thorsten Barnhofer et al. 13 citations

Older adults with subjective cognitive decline (SCD) recruited from memory clinics are at higher risk for dementia and often have reduced well-being due to memory concerns and fear of dementia. A randomized trial compared an 8-week caring mindfulness-based approach for seniors (CMBAS) with a health self-management program (HSMP) in 147 participants. The mindfulness program showed a small advantage over HSMP in improving a sense of connection immediately after the intervention. However, overall psychological well-being, quality of life, and other composite measures did not increase in either group. The findings suggest that these brief non-pharmacological interventions had only limited effects on well-being in SCD.

The Effect of Meditation-Based Interventions on Patients with Fatigue Symptoms: A Systematic Review and Meta-Analysis.

Psychologica Belgica January 1, 2023 Florence Requier, Harriet Demnitz-King, Tim Whitfield et al. 12 citations

Meditation-based interventions reduce fatigue in people with chronic diseases, with a moderate overall effect (g = 0.62). The benefit is larger when meditation is compared against no treatment (passive control, g = 0.83) than against other active treatments. The review included 34 randomized controlled trials covering six conditions, mostly cancer (68%). Evidence suggests meditation is a useful non-pharmacological approach for pathological fatigue, though more studies are needed to clarify effects by meditation type, condition, and fatigue type (physical vs. mental).

The effect of mindfulness‐based programs on cognitive performance across the lifespan: A systematic review and meta‐analysis

Alzheimer s & Dementia December 1, 2020 Tim Whitfield, Thorsten Barnhofer, Rebecca L. Acabchuk et al. 6 citations

A systematic review and meta-analysis of 46 studies examined whether mindfulness-based programs improve cognitive performance across the adult lifespan. When combining healthy and clinical studies of working-age adults (18–65 years), there was no significant effect of mindfulness training on cognitive performance compared to control conditions. However, a small but significant positive effect was observed for older adults (over 65), including those with subjective or objective cognitive impairment. The cognitive domains most frequently measured were executive function and attention. The findings suggest that mindfulness-based programs may confer cognitive benefits primarily for older adults, with no evidence of benefit for younger populations.

Decoding meditation mechanisms underlying brain preservation and psycho-affective health in older expert meditators and older meditation-naive participants.

Sci Rep November 27, 2024 Sacha Haudry, Anne-Laure Turpin, Brigitte Landeau et al. 3 citations

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.

Meditation dosage predicts self- and teacher-perceived responsiveness to an 18-month randomised controlled trial

Scientific Reports November 2, 2024 Marco Schlosser, Julie Gonneaud, Stefano Poletti et al. 2 citations

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.

Examining cognitive differences in expert meditators and non-meditators older adults.

Scientific Reports May 15, 2025 Florence Requier, Hamed Mohammadi, Harriet Demnitz-King et al.

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.

The evolution of subjective cognition after meditation training in older people: a secondary analysis of the three-arm age-well randomized controlled trial.

Neuropsychology, development, and cognition. Section B, Aging, neuropsychology and cognition March 1, 2025 Florence Requier, Harriet Demnitz-King, Eric Frison et al.

Meditation training, compared to non-native language training, reduced older adults' self-reported vulnerability to external distractions after 18 months, but did not change their perception of internal attention or overall cognitive difficulties. The study included 134 healthy older adults randomly assigned to meditation, language training, or no intervention. Results suggest meditation may help older adults manage distracting information in daily life.
