Mindfulness and Cognitive Health in Aging

A growing body of research suggests that mindfulness and mind–body practices may support cognitive health as we age. Recent studies have found improvements in memory, executive function, and overall cognitive performance, along with better sleep and changes in neurovascular processes, particularly among adults with subjective cognitive decline, mild cognitive impairment, or early Alzheimer’s disease.

Effects of Mindfulness-Based Tai Chi Chuan on Physical Performance and Cognitive Function among Cognitive Frailty Older Adults: A Six-Month Follow-Up of a Randomized Controlled Trial

Abstract

Background: The Objective - To assess the effectiveness of a mindfulness-based Tai Chi Chuan on physical performance and cognitive function among cognitive frailty older adults.

Design: A single-blind, three-arm randomized controlled trial.

Setting: Three communities in Daqing, China.

Participants: The study sample comprised 93 men and women aged 65 years or older who were able to walk more than 10 m without helping tools, scored 0.5 on Clinical Dementia Rating (CDR) and absence of concurrent dementia, identified pre-frailty (scored 1–2 on Fried Frailty Criteria) and frailty older adults (scored 3–5 on Fried Frailty Criteria).

Intervention: Subjects were randomly allocated to three groups: Group1, which received mindfulness intervention (formal and informal mindfulness practices); Group 2, which received Tai-Chi Chuan intervention; Group 3, which received MTCC intervention.

Measurements: The primary outcomes was cognitive frailty rate(measured by Fried Frailty Criteria and Clinical Dementia Rating-CDR), the secondary outcome were cognitive function (measured by Min-Mental State Examination-MMES) and physical level (measured by Short physical performance battery-SPPB, Timed up and Go test-TUG and the 30-second Chair test). They were all assessed at Time 1-baseline, Time 2-after the end of 6-month intervention and the follow up (Time 3-half year after the end of 6-month intervention).

Results: The baseline characteristics did not differ among the groups. Improvements in the cognitive function (MMES), physical performance (SPPB, TUG, 30-second Chair test) were significantly difference between time-group interaction (p<.05). The rate of CF was significantly different among groups at 6-month follow-up period (χ2=6.37, p<.05). A lower prevalence of frailty and better cognitive function and physical performance were found in the Group 3 compared with other two groups at the follow-up period (p<.05). Conclusions: MTCC seems to be effectively reverse CF, improving the cognitive and physical function among older adults, suggesting that MTCC is a preferably intervention option in community older adults with cognitive frailty.

The Impact of Kundalini Yoga on Cognitive Function and Memory: A Systematic Review of Randomized Controlled Trials

Abstract

Cognitive decline and dementia are significant public health challenges influenced by various modifiable and non-modifiable risk factors. Kundalini yoga (KY) has emerged as a promising non-pharmacological intervention to enhance cognitive function and memory in older adults at risk of cognitive decline. This systematic review aims to evaluate the effects of KY on cognitive function, memory impairment, and related neurobiological and psychological outcomes in older adults. A comprehensive literature search was conducted across PubMed, MEDLINE, Scopus, Web of Science, and the Cochrane Library, covering studies published from January 2000 to December 2023. Randomised controlled trials (RCTs) were included to compare KY with other cognitive enhancement strategies, such as memory enhancement training (MET) and psychoeducation. Five RCTs with 215 participants met the inclusion criteria. The studies varied in sample size (11 to 81 participants) and duration (12 to 24 weeks). The participants were older adults (≥55 years) with mild cognitive impairment (MCI) or subjective cognitive decline (SCD). The interventions compared KY with MET or psychoeducation. KY consistently improved memory performance and executive function. Significant mood enhancements, increased hippocampal volume, and better neural connectivity were observed. KY also reduced pro-inflammatory cytokines and altered ageing-related gene expression, demonstrating both cognitive and neurobiological benefits. KY appears to be a promising intervention for enhancing cognitive function, mood, and neurobiological health in older adults at risk of cognitive decline and dementia. While further research with more extensive, well-designed RCTs is needed to confirm these findings and optimise intervention strategies, the existing evidence supports the integration of KY into cognitive health programmes. Practitioners should ensure proper training and gradual progression to maximise benefits and minimise risks.

Three potential neurovascular pathways driving the benefits of mindfulness meditation for older adults

Abstract

Mindfulness meditation has been shown to be beneficial for a range of different health conditions, impacts brain function and structure relatively quickly, and has shown promise with aging samples. Functional magnetic resonance imaging metrics provide insight into neurovascular health which plays a key role in both normal and pathological aging processes. Experimental mindfulness meditation studies that included functional magnetic resonance metrics as an outcome measure may point to potential neurovascular mechanisms of action relevant for aging adults that have not yet been previously examined. We first review the resting-state magnetic resonance studies conducted in exclusively older adult age samples. Findings from older adult-only samples are then used to frame the findings of task magnetic resonance imaging studies conducted in both clinical and healthy adult samples. Based on the resting-state studies in older adults and the task magnetic resonance studies in adult samples, we propose three potential mechanisms by which mindfulness meditation may offer a neurovascular therapeutic benefit for older adults: (1) a direct neurovascular mechanism via increased resting-state cerebral blood flow; (2) an indirect anti-neuroinflammatory mechanism via increased functional connectivity within the default mode network, and (3) a top-down control mechanism that likely reflects both a direct and an indirect neurovascular pathway.

Meditation for subjective cognitive decline, mild cognitive impairment and Alzheimer’s disease: a systematic review and meta-analysis of randomized controlled trials

Abstract

Background: Meditation has gained increasing recognition as a simple, cost-effective, and non-invasive therapeutic approach for older adults with subjective cognitive decline (SCD), mild cognitive impairment (MCI), and Alzheimer’s disease (AD). This meta-analysis aimed to systematically evaluate its effectiveness on this population.

Methods: A comprehensive search across nine databases was performed from inception to April 1, 2024, to identify eligible randomized controlled trials (RCTs). The primary outcome was global cognitive performance measured by the Mini-Mental State Examination (MMSE), while the secondary outcomes included sleep quality estimated through the Pittsburgh Sleep Quality Index (PSQI), health status assessed using the 36-Item Short Form Health Survey (SF-36), and depression evaluated with the Geriatric Depression Scale (GDS). This meta-analysis utilized R 4.3.1 software and adhered to the Cochrane Handbook and PRISMA reporting guidelines.

Results: A total of 25 RCTs published between 2013 and 2024 involving 2,095 participants were included in this study. The pooled findings demonstrated that meditation significantly improved global cognitive performance (MD 2.22, 95% CI: 0.83–3.62, p = 0.002), sleep quality (MD −1.40, 95% CI: −2.52 to −0.27, p = 0.015), and health status (MD 3.50, 95% CI, 0.45–6.56, p = 0.020). However, no significant effect was observed on depression compared to the control group (SMD −0.16, 95% CI: −0.63 to 0.31, p = 0.514).

Conclusion: This meta-analysis suggests that meditation is an effective adjunct therapy for improving global cognitive performance, sleep quality, and health status in older adults with SCD, MCI, and AD. However, given the heterogeneity and limited sample sizes, these findings should be interpreted with caution. More large-scale and high-quality RCTs are needed to further substantiate these effects.
