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).

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.

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.
