Mindfulness-based stress reduction in middle-aged and older adults with memory complaints: a mixed-methods study

Cognitive, psychological, and physiological effects of a web-based mindfulness intervention in older adults during the COVID-19 pandemic: an open study

BACKGROUND

The development of effective strategies to maintain good mental health of older adults is a public health priority. Mindfulness-based interventions have the potential to improve psychological well-being and cognitive functions of older adults, but little is known about the effect of such interventions when delivered through internet. During the COVID-19 pandemic we evaluated short- and long-term cognitive, psychological, and physiological effects of a mindfulness-based intervention (MBI) delivered via web-based videoconference in healthy older adults.

METHODS

Fifty older adults participated in an 8-week MBI, which comprised structured 2-h weekly group sessions. A comprehensive evaluation encompassing cognitive (verbal memory, attention and processing speed, executive functions) and psychological assessments (depression and anxiety symptoms, mindfulness, worries, emotion regulation strategies, well-being, interoceptive awareness and sleep) was conducted. Additionally, electroencephalography (EEG) data were recorded before and after the MBI and at the 6-month follow-up (T6). Data were analyzed using an intention-to-treat approach, using linear mixed models adjusted for age. The effect size for time was computed as omega squared.

RESULTS

We observed significant improvements from pre-MBI to post-MBI and at the T6 across several measures. These improvements were notable in the areas of verbal memory (California Verbal Learning Test, p ≤ .007), attention and executive functions (Trail Making Test A and BA, p < .050), interoceptive awareness (Multidimensional Assessment of Interoceptive Awareness, p = .0002 for self-regulation and p < .05 for noticing, body listening, and trusting dimensions), and rumination (Heidelberg Form for Emotion Regulation Strategies, p = .018). These changes were associated with low to medium effect size. Moreover, we observed significant changes in EEG patterns, with a decrease in alpha1 (p = .004) and an increase in alpha2 (p < .0001) from pre-MBI to T6. Notably, improvements in TMTBA and rumination were correlated with the decrease in alpha1 (p < .050), while improvements in TMTA were linked to the increase in alpha2 (p = .025).

CONCLUSIONS

The results of our study show that a web-based MBI in older adults leads to improvements in cognitive and psychological measures, with associated modulations in specific brain rhythms. While these findings are promising, further controlled studies are required to validate these preliminary results.

Meditation and Cognitive Outcomes: A Longitudinal Analysis Using Data From the Health and Retirement Study 2000-2016

Objective

We aimed to assess the association between meditation practice and cognitive function over time among middle-aged and older adults.

Method

We included Health and Retirement Study (HRS) participants assessed for meditation practice in the year 2000 as part of the HRS alternative medicine module (n = 1,160) and were followed up for outcomes over 2000-2016 period. We examined the association between meditation ≥ twice a week vs none/less frequent practice and changes in the outcomes of recall, global cognitive function, and quantitative reasoning using generalized linear regression models. Stratified analyses among persons with/without self-reported baseline depressive symptoms were conducted to assess the link between meditation and cognitive outcomes.

Results

Among our full study sample, meditation ≥ twice a week was not significantly associated with total recall [β ; 95% CI: -0.97, 0.57; p = 0.61], global cognitive function [β ; 95% CI: -1.01, 1.12; p = 0.92], and quantitative reasoning [β ; 95% CI: -31.27, 8.32; p = 0.26]. However, among those who did not have self-reported depressive symptoms at baseline, meditation ≥ twice a week was associated with improvement in cognitive outcomes such as total recall [β ; 95% CI: 0.03, 0.18; p = 0.01] and global cognitive function [β ; 95% CI: 0.05, 0.40; p = 0.01] over time.

Conclusions

Frequent meditation practice might have a protective effect on cognitive outcomes over time, but this protection could be limited to those without self-reported baseline depressive symptoms. Future studies could incorporate more precise meditation practice assessment, investigate the effect of meditation on cognitive outcomes over time, and include more rigorous study designs with randomized group assignment.

The effect of the Mindfulness-Based Stress Reduction program on the level of perceived stress and geriatric depression in older adults: a randomised controlled study

BACKGROUND

This study aims to reveal the effect of the Mindfulness-Based Stress Reduction (MBSR) program on the perceived stress and geriatric depression levels of older adults.

METHODS

The data of this randomised controlled experimental study were obtained from older adults living in a nursing home in Turkey, between May and November, 2021. The target population consisted of 54 older adults living in the specified nursing home, and the sample consisted of 48 older adults who met the inclusion criteria (n = 24 intervention group, n = 24 control group). The MBSR program was applied to the older adults in the intervention group. Data were collected using the Personal Information Form, the Perceived Stress Scale, and the Geriatric Depression Scale-Short Form.

RESULTS

It was revealed that the MBSR program led to a 54.7% decrease in the perceived stress total scores of the participants, and a 49.9% and 49.8% decrease in the sub-dimensions of perceived insufficient self-efficacy and perceived stress/distress, respectively. It was also found that the program reduced geriatric depression scores by 14.1% and created a significant effect (P < 0.05).

CONCLUSIONS

It can be concluded that the MBSR program is an effective method in reducing the perceived stress and geriatric depression levels of older adults. This effect has been maintained 1 month after the completion of the program.

Mindfulness-based stress reduction for community-dwelling older adults with subjective cognitive decline (SCD) and mild cognitive impairment (MCI) in primary care: a mixed-methods feasibility randomized control trial

BACKGROUND

Primary care is often the first point of contact when community-dwelling older adults experience subjective cognitive decline (SCD) or mild cognitive impairment (MCI). Living with SCD or MCI can be life-altering, resulting in low mood and increased anxiety, further exacerbating cognitive decline. However, there is scant literature on interventions that interprofessional primary care providers can provide to support those living with SCD or MCI. Practicing mindfulness-based stress reduction (MBSR) in an interprofessional primary care setting may support emotional health and well-being for those with cognitive decline, but it has not been studied in an interprofessional primary care context.

OBJECTIVES

This study's primary aim was to determine the feasibility of, and perceived benefits to and satisfaction with, a 9-Week MBSR program delivered in a team-based primary care setting. The secondary aim was to examine the acceptability of using technology (computer tablet and App Insight Timer®) for program delivery and home practice.

METHODS

A convergent mixed-methods, single-blind pilot randomized controlled trial (RCT) study design was used. A quantitative strand was used to evaluate the feasibility of the MBSR program. The qualitative strand used a focus group with older adult participants with SCD or MCI. Individual semi-structured interviews with occupational therapists who are qualified-MBSR teachers were conducted to explore the acceptability of using computer tablets for program delivery and home practice.

RESULTS

27 participants were randomized (14 MBSR; 13 Control) with retention rates of 64.3% (9/14 completed ≥6 sessions), true adherence rates of 50% (7/14 met ≥19.5 hrs of home practice), 21.4% attrition rates, and 100% post-intervention follow-up. No participants who used computer tablets at the beginning of the intervention switched to low technology. Older adult participants found the use of computer tablets in the MBSR course acceptable and appreciated the portability of the tablets.

CONCLUSIONS

Based on the lower-than-expected rates of recruitment, retention, and adherence, our study, as designed, did not meet the feasibility benchmarks that were set. However, with minor modifications to the design, including changing how participants who drop-out are analyzed, extending recruitment, and adding multiple sites, this intervention would be well suited to further study using a full-scale RCT. However, we found that embedding MBSR in an interprofessional primary care setting was feasible in practice and qualitative data highlighted the satisfaction and perceived benefits based on the intervention. The use of technology was acceptable and portable, as participants utilized their computer tablets consistently until the study's end. Our study showed that older adults living with SCD or MCI were highly receptive to learning how to use technology, and future group intervention programs in interprofessional primary care settings may also incorporate tablet use.

Common Neuropsychiatric S ymptoms in Alzheimer's Disease, Mild Cognitive Impairment, and Subjective Memory Complaints: A Unified Framework

The Alzheimer's disease (AD) continuum is a unique spectrum of cognitive impairment that typically involves the stages of subjective memory complaints (SMC), mild cognitive impairment (MCI), and AD dementia. Neuropsychiatric symptoms (NPS), such as apathy, anxiety, stress, and depression, are highly common throughout the AD continuum. However, there is a dearth of research on how these NPS vary across the AD continuum, especially SMC. There is also disagreement on the effects of specific NPS on each stage of the AD continuum due to their collinearity with other NPS, cognitive decline, and environmental factors (e.g., stress). In this article, we conduct a novel perspective review of the scientific literature to understand the presence of NPS across the AD continuum. Specifically, we review the effects of apathy, depression, anxiety, and stress in AD, MCI, and SMC. We then build on this knowledge by proposing two theories of NPS' occurrence across the AD continuum. Consequently, we highlight the current landscape, limitations (e.g., differing operationalization), and contentions surrounding the NPS literature. We also outline theories that could clear up contention and inspire future NPS research.

The Effects of Mindfulness Interventions on Fibromyalgia in Adults aged 65 and Older: A Window to Effective Therapy

Pain usually receives insufficient attention by individuals due to the misconception that pain is a natural consequence of aging. For persons aged 65 and older, a disease requiring further research is fibromyalgia, characterized by chronic pain without clear pathology. Mind-body therapies like mindfulness are beneficial for this population as they affect psychological and biological aspects of pain. These therapies emphasize a nonjudgmental acceptance of thoughts and attention to the experience without attempting to resist or change them. Despite the potential benefits of mindfulness interventions for persons with fibromyalgia aged 65 and older, only few studies have examined the effects of these therapies, yielding conflicting findings. Importantly, no study has yet to be conducted exclusively on this population. This comprehensive review examined existing literature focusing on the effects of mindfulness-based interventions on the physical and mental well-being of persons with fibromyalgia aged 65 and older. It highlights the need for further research on the relationship between mindfulness, fibromyalgia, and gerontology, calling for a standard protocol of intervention.

Higher levels of neuroticism in older adults predict lower executive functioning across time: the mediating role of perceived stress

Neuroticism has been associated with individual differences across multiple cognitive functions. Yet, the literature on its specific association with executive functions (EF) in older adults is scarce, especially using longitudinal designs. To disentangle the specific influence of neuroticism on EF and on coarse cognitive functioning in old adulthood, respectively, we examined the relationship between neuroticism, the Trail Making Test (TMT) and the Mini-Mental State Examination (MMSE) in a 6-year longitudinal study using Bayesian analyses. Data of 768 older adults (M age = 73.51 years at Wave 1) were included in a cross-lagged analysis. Results showed no cross-sectional link between neuroticism and TMT performance at Wave 1 and no longitudinal link between neuroticism at Wave 1 and MMSE at Wave 2. However, neuroticism at Wave 1 predicted TMT performance at Wave 2, indicating that the more neurotic participants were, the lower they performed on the TMT six years later. Additional analyses showed that this relation was fully mediated by participants' perceived stress. Our results suggest that the more neurotic older adults are the more stress they may perceive six years later, which in turn negatively relates to their EF. In sum, this study demonstrates that neuroticism may lead to lower EF in older age across six years. It further suggests older adults' perceived stress as mediator, thereby providing novel insights into the mechanisms underlying this relation. Possible intervention approaches to counter these effects are discussed.

Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy for Depression: a Systematic Review of Cognitive Outcomes

Objectives

Summarize existing literature on cognitive outcomes of MBSR and MBCT for individuals with depression.

Methods

Following PRISMA (2021) guidance, we conducted a systematic review. We searched databases for studies published from 2000 to 2020 which examined cognitive outcomes of MBSR and MBCT in individuals with at least mild depressive symptoms. The search result in 10 studies (11 articles) meeting inclusion criteria.

Results

We identified five single armed trials and five randomized controlled trials. Results indicated that three studies did not show any improvements on cognitive outcomes, and seven studies showed at least one improvement in cognitive outcomes.

Conclusions

Overall, the review highlighted several inconsistencies in the literature including inconsistent use of terminology, disparate samples, and inconsistent use of methodology. These inconsistencies may help to explain the mixed results of MBSR and MBCT on cognitive outcomes. Recommendations include a more streamlined approach to studying cognitive outcomes in depressed individuals in the context of MBSR and MBCT.

Effects of a Mindfulness-Based Intervention versus Health Self-Management on Subclinical Anxiety in Older Adults with Subjective Cognitive Decline: The SCD-Well Randomized Superiority Trial

INTRODUCTION

Older adults experiencing subjective cognitive decline (SCD) have a heightened risk of developing dementia and frequently experience subclinical anxiety, which is itself associated with dementia risk.

OBJECTIVE

To understand whether subclinical anxiety symptoms in SCD can be reduced through behavioral interventions.

METHODS

SCD-Well is a randomized controlled trial designed to determine whether an 8-week mindfulness-based intervention (caring mindfulness-based approach for seniors; CMBAS) is superior to a structurally matched health self-management program (HSMP) in reducing subclinical anxiety. Participants were recruited from memory clinics at 4 European sites. The primary outcome was change in anxiety symptoms (trait subscale of the State-Trait Anxiety Inventory; trait-STAI) from pre- to postintervention. Secondary outcomes included a change in state anxiety and depression symptoms postintervention and 6 months postrandomization (follow-up).

RESULTS

One hundred forty-seven participants (mean [SD] age: 72.7 [6.9] years; 64.6% women; CMBAS, n = 73; HSMP, n = 74) were included in the intention-to-treat analysis. There was no difference in trait-STAI between groups postintervention (adjusted change difference: -1.25 points; 95% CI -4.76 to 2.25) or at follow-up (adjusted change difference: -0.43 points; 95% CI -2.92 to 2.07). Trait-STAI decreased postintervention in both groups (CMBAS: -3.43 points; 95% CI -5.27 to -1.59; HSMP: -2.29 points; 95% CI -4.14 to -0.44) and reductions were maintained at follow-up. No between-group differences were observed for change in state anxiety or depression symptoms.

CONCLUSIONS

A time-limited mindfulness intervention is not superior to health self-management in reducing subclinical anxiety symptoms in SCD. The sustained reduction observed across both groups suggests that subclinical anxiety symptoms in SCD are modifiable. ClinicalTrials.gov identifier: NCT03005652.

Mindfulness and Cognitive Training Interventions in Mild Cognitive Impairment: Impact on Cognition and Mood

With the lack of disease-modifying pharmacologic treatments for mild cognitive impairment and dementia, there has been an increasing clinical and research focus on nonpharmacological interventions for these disorders. Many treatment approaches, such as mindfulness and cognitive training, aim to mitigate or delay cognitive decline, particularly in early disease stages, while also offering potential benefits for mood and quality of life. In this review, we highlight the potential of mindfulness and cognitive training to improve cognition and mood in mild cognitive impairment. Emerging research suggests that these approaches are feasible and safe in this population, with preliminary evidence of positive effects on aspects of cognition (attention, psychomotor function, memory, executive function), depression, and anxiety, though some findings have been unclear or limited by methodological weaknesses. Even so, mindfulness and cognitive training warrant inclusion as current treatments for adults with mild cognitive impairment, even if there is need for additional research to clarify treatment outcomes and questions related to dose, mechanisms, and transfer and longevity of treatment effects.

Protocol for a Nested Randomized Controlled Trial to Evaluate the Feasibility and Preliminary Efficacy of the Mindfulness Based Health Promotion Program on the Quality of Life of Older Adults Assisted in Primary Care-"The MBHP-Elderly Study"

Introduction: Population aging is a global phenomenon that has grown rapidly and progressively all over the world. Interventions that promote health must be studied and implemented to make the aging process be with quality of life. Depression and anxiety are the most common mental health conditions that compromise the quality of life on the elderly and it can cause damage to the autonomy and activities of daily life. Mindfulness training has been shown to improve psychological health and quality of life on adults. Studies involving Mindfulness-Based Interventions (MBIs) with older people are scarce in the literature, but they have been increasing in recent years showing promising results for healthy aging. This trial will investigate the feasibility and preliminary efficacy of an MBI on the quality of life of elderly assisted in the Primary Care.

Materials and Methods: A cohort-nested randomized controlled trial with 3 assessment points (baseline, post-intervention and 1-year follow up) will be conducted to compare a MBI program (Mindfulness-Based Health Promotion) to a cognitive stimulation control-group in a Primary Care facility. One-hundred and two older adults will be recruited from a cohort of this facility and they will be randomized and allocated into an intervention group (N = 76) and the control group (N = 76). The primary outcome evaluated will be the improvement of quality of life assessed by the WHOQOL-BREF and WHOQOL-OLD. The secondary outcomes will be cognitive function, psychological health, sleep quality, self-compassion, and religiosity. Qualitative data will be assessed by focus group and the word free evocation technique. The feasibility of the program will also be evaluated by adherence and unwanted effects questionnaires.

Discussion: This cohort-nested clinical trial will be the first mixed-methods study with 3 assessment points which will study the feasibility and preliminary efficacy of a mindfulness-based program for older people in Latin America population. If the findings of this study confirm the effectiveness of this program in this population it will be possible to consider it as intervention that might be implemented as public policy addressed to older people in healthcare systems.

The Interpersonal Context of Memory Complaints

This mixed-methods study was designed to investigate the interpersonal experience of having memory problems using a community-dwelling sample of 94 adults over the age of 50 (M age = 72.35, SD = 10.51). Participants were asked a series of open-ended questions about their reactions to memory problems and completed questionnaires about memory, personality, and health. Qualitative findings suggest a few clear patterns of response (e.g., admitting the problem, ignoring the problem) to memory failures. In addition, endorsing avoidance of talking to certain people was related to worry and memory anxiety. Correlations showed subjective memory related to conscientiousness, neuroticism, depression, and worry which replicates previous studies about memory complaints. This study adds to the subjective memory literature by enhancing what we know about what people do when they are confronted with a memory challenge as well as to whom they will or will not speak about their complaints.

Exploring Cancer Patients' Experiences of an Online Mindfulness-Based Program: A Qualitative Investigation

Objective

Chronic neuropathic pain (CNP) is a common condition cancer survivors experience. Mindfulness training may be one approach to address the psychosocial factors associated with CNP. The purpose of this study was to understand patients’ experiences in an 8-week online mindfulness-based program (MBP), including techniques and skills learned and applied, barriers to practice, and research experiences.

Methods

Nineteen participants who were part of a randomized controlled trial consented to participate in a telephone interview or submit written responses via email post-course. Interviews were transcribed and analyzed using the principles of Applied Thematic Analysis (ATA).

Results

Predominant themes identified in participant interviews included (1) common humanity, (2) convenience, (3) teacher resonance, (4) perceived relaxation and calm, (5) pain and stress management, (6) half-day session, and (7) mindful breathing. Participants also identified helpful strategies learned and implemented from the course, as well as barriers to practice, and key components of their experiences in a randomized controlled trial, including a sense of disconnection post-course and needing continued ongoing sessions, and the importance of the facilitators’ skills in creating a comfortable and supportive space.

Conclusions

An online group-based MBP may offer a more accessible resource and form of psychosocial intervention and support for cancer survivors living with CNP. Furthermore, the need and consideration for implementing ongoing group maintenance sessions to minimize participants’ feelings of disconnect and abandonment post-course and post-study are warranted in future MBP development.

Psychological well-being and happiness among Middle-aged women: A cross-sectional study

Biological, physical, and psychosocial changes that occur during the aging process can negatively impact women's mental health and happiness at midlife. In this cross-sectional study, we aimed to determine the level of psychological well-being and happiness among middle-aged women in Tabriz. Data were collected from December 2017 to February 2018 by face-to-face interviews, using structured questionnaires of happiness and psychological well-being. The participants were 40-60-year-old middle-aged women (n = 300) selected by clustered random sampling allocation. A total of 167 (55.7%) out of all the women had decreased levels of psychological well-being. Psychological well-being was found to be significantly lower among the women with low levels of happiness (B: 24.43, CI (18.57 to 30.29), p < 0.001). Health care centers should implement more comprehensive mental health promotion programs for middle-aged women, including free of charge recreational opportunities (e.g., walking, swimming, dancing) to improve psychological health and well-being.

Brain Health across the Lifespan: A Systematic Review on the Role of Omega-3 Fatty Acid Supplements

The brain is the most significant and complex organ of the human body. Increasingly, we are becoming aware that certain nutrients may help to safeguard brain health. An expanse of research has investigated the effects of omega fatty acids in relation to brain health but effects across the lifespan have not been widely evaluated. The present systematic review collated evidence from 25 randomized controlled trials (n = 3633) published since 2013. Compared with control groups, omega-3 supplementation generally correlated with improvements in blood biomarkers. Subsequently, these appear to benefit those with lower baseline fatty acid levels, who are breastfeeding or who have neuropsychiatric conditions. Whilst multiple studies indicate that omega fatty acids can protect against neurodegeneration in older adults, more work is needed in the years preceding the diagnosis of such medical conditions. Bearing in mind the scale of ageing populations and rising healthcare costs linked to poor brain health, omega supplementation could be a useful strategy for helping to augment dietary intakes and support brain health across the lifespan. Ongoing research is now needed using harmonious methodologies, supplement dosages, ratios and intervention periods to help formulate congruent conclusions.

Mindfulness Training for People With Dementia and Their Caregivers: Rationale, Current Research, and Future Directions

The world population is aging and the prevalence of dementia is increasing. By 2050, those aged 60 years and older are expected to make up a quarter of the population. With that, the number of people with dementia is increasing. Unfortunately, there is no cure for dementia. The progression of symptoms with no hope of improvement is difficult to cope with, both for patients and their caregivers. New and evidence-based strategies are needed to support the well-being of both caregiver and patient. Mindfulness training is a body-mind intervention that has shown to improve psychological well-being in a variety of mental health conditions. Mindfulness, a non-judgmental attention to one's experience in the present moment, is a skill that can be developed with a standard 8-week training. Research has shown preliminary but promising results for mindfulness-based interventions to benefit people with dementia and caregivers. The aim of this review is (a) to provide a rationale for the application of mindfulness in the context of dementia care by giving an overview of studies on mindfulness for people with dementia and/or their caregivers and (b) to provide suggestions for future projects on mindfulness in the context of dementia and to give recommendations for future research.
