Abstract
OBJECTIVES To assess whether mindfulness-based interventions (MBIs) affect mental health and cognitive abilities in older adults. METHODS A systematic search was performed in PubMed, SCOPUS, Web of Science, and Google Scholar up to June 2023. Weight mean difference and 95% confidence intervals were provided as summary statistics. RESULTS In total, 26 articles were eligible. Overall, MBIs showed a statistically significant improvement in depression, anxiety, quality of life, and working memory compared to controls. However, no significant effects of MBIs on other cognitive parameters were found. In moderator analysis, less than eight weeks of MBIs showed greater improvement in anxiety and quality of life than longer periods. There was no evidence for publication bias. DISCUSSION Mindfulness-based interventions can be an encouraging alternative in place of conventional treatments in improving depression, anxiety, quality of life and working memory in cognition among older adults. However, findings strongly recommend future research to have definite conclusion.

Abstract
La maladie d'Alzheimer se manifeste par des troubles de la mémoire et un déclin cognitif plus général, le plus souvent associés à des troubles de l'humeur et du comportement. Les traitements médicamenteux ayant une efficacité assez modeste, il apparaît nécessaire de leur associer une prise en charge non pharmacologique. La méditation de pleine conscience, qui a des effets bénéfiques sur le fonctionnement cognitif et sur l'état émotionnel, semble être une piste intéressante. Cette revue de littérature narrative se propose de recenser les études ayant testé l'efficacité d'une intervention basée sur la pleine conscience auprès de personnes souffrant de la maladie d'Alzheimer ou à risque de développer cette maladie. Il apparaît que ces interventions présentent un intérêt pour réduire les symptômes cognitifs (troubles attentionnels et mnésiques notamment) et émotionnels (affects dépressifs et anxiété en particulier). Cependant, elles nécessitent un certain nombre de modifications pour être adaptées à ce public.

Abstract
OBJECTIVES This randomized controlled trial aimed to assess the efficacy of the Homebound Elderly People Psychotherapeutic Intervention (HEPPI), a home-delivered cognitive-emotional intervention, among the homebound older population presenting with mild cognitive impairment and depressive or anxiety symptoms. METHODS Participants were randomly assigned either to the intervention group or the treatment-as-usual group and completed baseline, post-intervention, and three-month follow-up assessments. Changes in episodic memory and symptoms of depression and anxiety were the primary outcomes. Secondary outcomes included changes in global cognition, attentional control, subjective memory complaints, functional status, and quality of life. Data were analyzed on an intention-to-treat basis employing a linear mixed models approach. ClinicalTrials.gov identifier: NCT05499767. RESULTS Compared with the treatment-as-usual group, the HEPPI group reported significant immediate improvement in cognition, mood, and daily functional performance. Positive effects of HEPPI were maintained over the follow-up phase only in depressive symptomatology, perceived incapacity to perform advanced instrumental activities of daily living, and self-reported emotional ability. A significant impact of the intervention on the subjective memory complaints level was observed only three months after the intervention. CONCLUSIONS This study suggests that HEPPI may be a promising home-delivered cognitive-emotional intervention to help homebound older adults improve their mental health.

Abstract
AIMS To evaluate the effectiveness of mindfulness-based interventions (MBIs) on mental and cognitive outcomes including, anxiety, depression, attention, memory, global cognition and neuroplastic changes in older adults with mild cognitive impairment (MCI). DESIGN Systematic review and meta-analysis. DATA SOURCE A three-step search strategy was conducted on eight electronic databases, grey literature and reference lists from inception to February 2022. REVIEW METHODS Randomized controlled trials (RCTs) examining MBIs on older adults with MCI were screened and assessed for risk of bias using the Cochrane Risk of Bias Tool. Meta-analysis was conducted using RevMan using a random-effect model. Narrative synthesis was performed for studies where results could not be pooled statistically. RESULTS Ten RCTs were included in the review. Results suggested that right frontal parietal and left inferior temporal gyrus of the brain showed increased cortical thickness after receiving MBIs. There were significant interaction effects for global efficiency and significant interactions in the insular and gyrus regions. Functional connectivity between the posterior cingulate cortex, bilateral medial prefrontal cortex and left hippocampus were increased in participants undergoing MBIs. Nevertheless, meta-analysis showed non-significant pooled effects, favouring control groups on anxiety, depression, attention, memory and global cognition. CONCLUSION This review suggested the potential effects of MBIs in improving cortical thickness and connectivity in regions associated with memory and attention. Nevertheless, the effects of MBIs compared to active control groups on depression, anxiety, attention, memory and global cognition are inconclusive due to the lack of studies and non-significant results. IMPACT The review advocates for more rigorous studies with larger sample size and utilizing wait-list controls to evaluate the effects of MBIs. MBIs can be considered as an adjunct with other therapies to further enhance the effect on psychological and cognitive outcomes for older adults with MCI. No Patient or Public Contribution as this is a meta-analysis.

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.

Abstract
OBJECTIVE Older adults are interested in mindfulness-based interventions with a meditation component for late life anxiety. This review examined the effectiveness of existing mindfulness-based interventions with a meditation component. METHODS This systematic review was registered with the Joanna Briggs Institute on 2021-05-17, was guided by Joanna Briggs Institute methodology and followed the PRISMA framework. Peer-reviewed randomized control trials were reviewed. A systematic literature search was conducted, using the following databases: MEDLINE (Ovid), Embase, Cochrane Database of Systematic Reviews, PsycINFO, CINAHL (EBSCO), and AMED. RESULTS Of 2709 studies screened, seven eligible randomized controlled trials were included representing 355 participants. Sample sizes ranged from 36 to 141. Mindfulness-based meditation interventions used varied. Regardless of the mindfulness-based meditation intervention used, a reduction in symptoms of anxiety in participants was reported post-intervention. Results are reported through narrative summary and tables. CONCLUSIONS Based on the emerging literature of randomized controlled trials, mindfulness-based interventions with a meditation component appear to be promising in reducing symptoms of anxiety in older adults. These findings demonstrate a need for further randomized controlled trials to guide clinical practice.

Abstract
OBJECTIVES This systematic review and meta-analysis examined the effects of mindfulness-based interventions (MBIs) on psychological symptoms, cognitive functions, and quality of life in older adults with dementia or mild cognitive impairment (MCI). METHODS A comprehensive search was conducted within four databases to identify relevant randomized controlled trials (RCTs). Heterogeneity was assessed using the I2 statistic. Depending on I2 statistic values, either a random effects model or fixed effects model was used. RESULTS 10 RCTs published in 11 articles met the eligibility criteria. The present meta-analysis study found no significant effect of MBIs on depressive symptoms, anxiety, quality of life, memory, and overall cognitive functions compared to control groups. CONCLUSIONS Future high-quality studies involving different types of MBIs are needed to better understand the effects of MBIs on psychological symptoms, quality of life, and cognitive functions in older adults with MCI and dementia and examine effective intervention features. CLINICAL IMPLICATIONS There is insufficient evidence to determine whether or not practitioners should be routinely providing MBIs to older adults with MCI and dementia due to the lack of studies currently.

Abstract
AbstractMild cognitive impairment (MCI) is a syndrome defined by objective cognitive deficits that do not impact functional independence. Individuals with MCI develop dementia at an annual rate of 10 to 15%. Neuropsychiatric symptoms (NPS) are common non-cognitive features of neurocognitive disorders and have a major impact on the wellbeing and quality of life of affected individuals and their families. Non-pharmacological interventions for NPS are considered the first-line treatment because of the limited efficacy and side-effect potential of current pharmacological agents. This article summarizes the literature on non-pharmacological treatments for NPS in MCI. The limited number of studies specific to individuals with MCI and its various etiologies, as well as the overall heterogeneity of research design and methodologies, make the evidence base inconclusive. Nevertheless, some studies support psychosocial interventions aimed at individuals with MCI and their caregivers.

Abstract
BACKGROUND Expanding technologies of early detection of Alzheimer's disease allow to identify individuals at risk of dementia in early and asymptomatic disease stages. Neuropsychiatric symptoms, such as anxiety and depression, are common in the course of AD and may be clinically observed many years before the onset of significant cognitive symptoms. To date, therapeutic interventions for AD focus on pharmacological and life style modification-based strategies. However, despite good evidence for psychotherapy in late-life depression, evidence for such therapeutic approaches to improve cognitive and emotional well-being and thereby reduce psychological risk factors in the course of AD are sparse. METHODS A systematic review was conducted in PUBMED, PsycINFO, Web of Science, and Clinical Trials to summarize the state of evidence on psychotherapeutic and psychoeducational interventions for individuals at risk for Alzheimer's dementia. Eligible articles needed to apply a manualized and standardized psychotherapeutic or psychoeducational content administered by trained professionals for individuals with subjective cognitive decline or mild cognitive impairment and measure mental health, quality of life or well-being. RESULTS The literature search yielded 32 studies that were included in this narrative summary. The data illustrates heterogeneous therapeutic approaches with mostly small sample sizes and short follow-up monitoring. Strength of evidence from randomized-controlled studies for interventions that may improve mood and well-being is scarce. Qualitative data suggests positive impact on cognitive restructuring, and disease acceptance, including positive effects on quality of life. Specific therapeutic determinants of efficacy have not been identified to date. CONCLUSIONS This review underlines the need of specific psychotherapeutic and psychoeducational approaches for individuals at risk of Alzheimer's dementia, particularly in terms of an early intervention aiming at improving mental health and well-being. One challenge is the modification of psychotherapeutic techniques according to the different stages of cognitive decline in the course of AD, which is needed to be sensitive to the individual needs.

Abstract
Mindfulness-based interventions (MBIs) have received increased clinical attention in
recent years. While some MBI research has focused on healthy older adults, research with
more emotionally and physically vulnerable populations, such as residents of long-term
care facilities (LTCFs), is lacking. The current paper presents quantitative and
qualitative results from a pilot study of an individual MBI designed for residents of
LTCFs. Participants included 8 residents from two skilled nursing facilities in the
southeastern United States. Data were collected between October 2016 through June 2017. A
modified MBI is proposed with specific adaptations for LTCF residents. Recommended
adaptations for LTCFs include a shift from a group to an individual format, individual
weekly instructor–participant meetings, removal of the yoga and full-day silent retreat
and shortening the duration of the formal practices. The current study found that these
adaptations result in an individual MBI that is accessible to most LTCF residents while
still providing the associated benefits of traditional group MBIs.

Abstract
The aim of this article was to systematically review the quality and efficacy of the current evidence for mindfulness-based interventions (MBIs) in patients with mild cognitive impairment (MCI), patients with dementia (PwD), and their caregivers. We identified 20 randomized controlled trials (RCTs) (11 for patients, 9 for caregivers) published in the last 15 years. Evidence suggested that MBIs are highly acceptable and credible treatments for patients with MCI, PwD and caregivers. Specifically, for PwD, the results indicated that the magnitude of post-treatment effects of MBIs are in the medium to large range for psychosocial outcomes, and in the small to medium range for cognitive functioning; however, treatment effects on dementia biomarkers were mixed, ranging from small to large, depending on the outcome measure. Findings also evidenced salutary effects of MBIs for caregivers of PwD, with post-treatment effects ranging from medium to large for caregiver stress and burden and large effects for quality of life, and mixed outcomes for cognitive functioning, with effects in the small to large range. However, confidence in these findings is relatively limited due to methodological limitations, especially in terms of poor consistency in intervention strategies, outcome measures, and other key criteria across studies. To better assess the value of MBIs for these populations and optimize treatment outcomes, we recommend further research with improved study methodology (e.g., multi-method assessment, universal criterion and outcome measures, use of active control groups, larger sample sizes, long-term follow-up) to replicate current findings and enhance our understanding of underlying treatment mechanisms of MBIs.

Abstract
Alzheimer's disease (AD) is a complex, multifactorial neurodegenerative disorder that represents a major and increasing global health challenge. In most cases, the first clinical symptoms of AD are preceded by neuropathological changes in the brain that develop years to decades before their onset. Therefore, research in the last years has focused on this preclinical stage of AD trying to discover intervention strategies that might, if implemented effectively, delay or prevent disease progression. Among those strategies, mind-body therapies such as yoga and meditation have gained increasing interest as complementary alternative interventions. Several studies have reported a positive impact of yoga and meditation on brain health in both healthy older adults and dementia patients. However, the underlying neurobiological mechanisms contributing to these effects are currently not known in detail. More specifically, it is not known whether yogic interventions, directly or indirectly, can modulate risk factors or pathological mechanisms involved in the development of dementia. In this article, we first review the literature on the effects of yogic practices on outcomes such as cognitive functioning and neuropsychiatric symptoms in patients with mild cognitive impairment and dementia. Then, we analyze how yogic interventions affect different risk factors as well as aspects of AD pathophysiology based on observations of studies in healthy individuals or subjects with other conditions than dementia. Finally, we integrate this evidence and propose possible mechanisms that might explain the positive effects of yogic interventions in cognitively impaired individuals.

Abstract
Objective To assess the effectiveness of mindfulness-based interventions on people with dementia and mild cognitive impairment. Methods We searched several electronic databases, namely Cochrane Library, EMBASE, and MEDLINE with no limitations for language or document type (last search: 1 February 2020). Randomized controlled trials of mindfulness-based interventions for people with dementia and mild cognitive impairment compared to active-control interventions, waiting lists, or treatment as usual were included. Predefined outcomes were anxiety symptoms, depressive symptoms, cognitive function, quality of life, mindfulness, ADL and attrition. We used the random effects model (DerSimonian-Laird method) for meta-analysis, reporting effect sizes as Standardized Mean Difference. Heterogeneity was assessed with the I2 statistics. Results Eight randomized controlled trials, involving 276 patients, met the eligibility criteria and were included in the meta-analysis. We found no significant effects for mindfulness-based interventions in either the short-term or the medium- to long-term on any outcomes, when compared with control conditions. The number of included studies and sample sizes were too small. Additionally, the quality of evidence was low for each randomized controlled trial included in the analysis. This is primarily due to lack of intent-to-treat analysis, high risk of bias, and imprecise study results. The limited statistical power and weak body of evidence prevented us from reaching firm conclusions. Conclusions We found no significant effects of mindfulness-based interventions on any of the outcomes when compared with control conditions. The evidence concerning the efficacy of mindfulness-based interventions in this population is scarce in terms of both quality and quantity. More well-designed, rigorous, and large-scale randomized controlled trials are needed.

Abstract
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.

Abstract
BACKGROUND Recent studies suggest meditation and music listening (ML) may improve cognitive and psychosocial outcomes in adults with subjective cognitive decline (SCD). However, lack of a usual care group has limited conclusions. OBJECTIVE To assess the: 1) feasibility of incorporating an enhanced usual care (EUC) comparator in a trial of Kirtan Kriya meditation (KK) and ML for adults experiencing SCD; and 2) preliminary effects of active treatment (KK/ML) versus an EUC program. METHODS Forty participants with SCD were randomized 1:1:2 to a 12-week KK, ML, or EUC program. KK and ML participants were asked to practice 12 minutes/day; EUC participants were given a comprehensive educational packet regarding healthy aging and strategies for improving/maintaining brain health and asked to record any activities or strategies used. Feasibility was assessed using measures of retention, adherence, treatment expectancies, and participant satisfaction, as well as information from exit questionnaires and daily practice/activity logs. Cognitive functioning, stress, mood, sleep-quality, and health-related quality of life (QOL) were measured pre- and post-intervention using well-validated instruments. RESULTS Thirty-two participants (80%) completed the 3-month study, with retention highest in the EUC group (p < 0.05). Active treatment participants averaged 6.0±0.4 practice sessions/week, and EUC participants, 7.5±0.6 brain health activities/week. Treatment expectancies were similar across groups. EUC participants indicated high satisfaction with the program and study. Despite limited study power, the active treatment group showed significantly greater gains in subjective memory functioning (ps≤0.025) and nonsignificant improvements in cognitive performance (TMT-B), perceived stress, QOL, and mood (ps≤0.08) compared to the EUC group. CONCLUSION Findings of this pilot feasibility trial suggest incorporation of an EUC program is feasible, and that participation in a simple 12-week relaxation program may be helpful for adults with SCD versus engagement in an EUC program.
