Impact of Yoga on cognition and mental health among elderly: A systematic review

Cross-sectional study of prevalence and correlates of fear of falling in the older people in residential care in India: the Hyderabad Ocular Morbidity in Elderly Study (HOMES)

OBJECTIVE

To report the prevalence and risk factors for the fear of falling (FOF) among older individuals living in residential care facilities in India.

DESIGN

Cross-sectional study.

SETTING

Homes for the aged centres in Hyderabad, India.

PARTICIPANTS

The study included individuals aged ≥60 years from homes for the aged centres. The participants underwent a comprehensive eye examination in make-shift clinics setup in homes. Trained investigators collected the personal and demographic information of the participants and administered the Patient Health Questionnaire-9 and Hearing Handicap Inventory for Elderly questionnaire in the vernacular language. FOF was assessed using the Short Falls Efficacy Scale. The presence of hearing and visual impairment in the same individual was considered dual sensory impairment (DSI). A multiple logistic regression analysis was done to assess the factors associated with FOF.

PRIMARY OUTCOME MEASURE

FOF.

RESULTS

In total, 867 participants were included from 41 homes for the aged centres in the analyses. The mean (±SD) age of the participants was 74.2 (±8.3) years (range 60-96 years). The prevalence of FOF was 56.1% (95% CI 52.7% to 59.4%; n=486). The multivariate analysis showed that those with DSI had eleven times higher odds of reporting FOF than those with no impairment (OR 11.14; 95% CI 3.15 to 41.4.) Similarly, those with moderate depression had seven times higher odds (OR 6.85; 95% CI 3.70 to 12.70), and those with severe depression had eight times higher odds (OR 8.13; 95% CI 3.50 to 18.90) of reporting FOF. A history of falls in the last year was also associated with increased odds for FOF (OR 1.52; 95% CI 1.03 to 2.26).

CONCLUSION

FOF is common among older individuals in residential care in India. Depression, falling in the previous year and DSI were strongly associated with FOF. A cross-disciplinary approach may be required to address FOF among the older people in residential care in India.

Reduced Anxiety and Depression and Improved Mood in Older Adults Living in Care Homes After Participating in Chair Yoga

Providing opportunities for older adults to engage in physical and mental activity is important to support healthy aging. The present preliminary study investigated the feasibility of accessible chair yoga for older adults in care homes. Chair yoga participants (n = 17) were assessed before and after attending twice weekly chair yoga sessions for 8 weeks, while control participants (n = 16) underwent the assessments only. Participant ages ranged from 80 to 101 years and included those living with mild to severe dementia. Anxiety and depression measured by the Hospital Anxiety and Depression Scale (HADS), and negative affect measured by the Positive and Negative Affect Schedule (PANAS), improved in the chair yoga but not the control group. Balance confidence (Modified Falls Efficacy Scale) and Health-related Quality of Life (EQ-5D-3L) were unchanged. Chair yoga is a feasible activity for older care home residents, including those living with dementia, with the potential to improve mental well-being.

Narrative Experiences of Individuals with Lower Limb Amputation: A Qualitative Study

Aim: The present study aimed to determine the narrative experiences of individuals undergoing lower limb amputation. Method: This study was a qualitative study conducted using the phenomenological pattern. Using purposive sampling, 13 individuals with lower limb amputation were selected and interviewed. Data were collected using semi-structured interviews and analyzed using the content analysis method. Results: The mean age of the 13 individuals was 51.17 ± 8.7 years. Five of the individuals were female and eight of them were male. A main theme and four sub-themes were identified. This main theme together with sub-themes were Dead End (Process of Loss, Negative Feelings, Change, Adapting to New Life). The individuals expressed mostly negative feelings and thoughts while also emphasizing the rehabilitation process (positive sides). Conclusions: Individuals with lower limb amputations stated there were positive factors affecting the rehabilitation process while emphasizing negative thoughts and feelings during the amputation process. These results can be used in planning for training, counseling and therapeutic interviews to protect the psychosocial health of individuals with lower limb amputation.

The impact of yoga on aging physiology: A review

Frailty represents diminished reserve across multiple physiologic systems, accompanied by increased vulnerability to stressors and increased morbidity and mortality. With population aging, strategies to prevent and manage frailty are priorities in clinical medicine and public health. Current evidence-based approaches to frailty management are multimodal in nature. Yoga, an increasingly popular and highly adaptable mind-body practice, is multi-component, incorporating physical postures, breathing practices, meditation, and other elements, and may be a strategy for frailty management. Here, we summarize the evidence linking yoga practice to mitigation of age-related degradation across multiple physiologic systems, including cardiovascular, pulmonary, musculoskeletal, and nervous systems. We discuss putative mechanisms of action including modulation of the hypothalamic-pituitary-adrenal axis. Finally, we consider implications for clinical practice and future research.

Holistic frailty prevention: The promise of movement-based mind-body therapies

Aging is characterized by fundamental cellular and molecular hallmarks that result in physiologic decline of most body systems. This may culminate in frailty, a state of decreased reserve. Because frailty is a state of multisystem dysregulation, multimodal interventions may be necessary to mitigate and prevent progression rather than interventions targeting a single system. Movement-based mind-body therapies, such as tai chi and yoga, are promising multimodal strategies for frailty prevention and treatment given their inherent multicomponent nature. In this review, we summarize the links between hallmarks of aging and frailty and how tai chi and yoga may impact these hallmarks. We review trial evidence for the impact of tai chi and yoga on frailty in older populations and discuss opportunities for future research.

Role of Yoga in Cardiovascular Diseases

Cardiovascular diseases are a collection of conditions that affect the blood vessels and the heart. These conditions include cardiac rehabilitation, hypertension, cardiac failure, rheumatic heart disease, peripheral artery disease, and coronary heart disease. Poor nutrition, alcohol, lack of exercise, smoking, etc are the main behavioral risk factors for heart disease. This study delivers a methodical review of yoga's role in the management and inhibition of cardiovascular diseases and their associated risk factors. This review suggests that proper maintenance of fitness and stress employing yoga effectively lowers cardiovascular disease. In this review, various asanas, and pranayama like Marjaryasana, Kapalabhati, Halasana, etc have been discussed. Also, their role in the prevention of coronary heart disease (CHD). In addition to this different metabolic syndrome associated with cardiovascular diseases and the relation of yoga with hypertension has been discussed. The review has documented satisfactory proof and concludes that yogic exercise enhances cardiovascular health and reduces associated risk factors.

Study protocol on effectiveness of yoga practice on composite biomarker age predictors (yBioAge) in an elderly Indian cohort- two-armed open label randomized controlled trial

INTRODUCTION

The recent development of robust indices to quantify biological aging, along with the dynamic epidemiological transitions of population aging generate the unmet need to examine the extent up to which potential interventions can delay, halt or temporarily modulate aging trajectories.

METHODS AND ANALYSIS

The study is a two-armed, open label randomised controlled trial. We aim to recruit 166 subjects, aged 60-75 years from the residential communities and old age clubs in Bangalore city, India, who will undergo randomisation into intervention or control arms (1:1). Intervention will include yoga sessions tailored for the older adults, 1 h per day for 5 days a week, spread for 12 months. Data would be collected at the baseline, 26th week and 52nd week. The primary outcome of the study is estimation in biological age with yoga practice. The secondary outcomes will include cardinal mechanistic indicators of aging- telomere length, interleukin-6 (IL-6), tumor necrosis factor receptor II (TNF-RII), high sensitivity c-reactive protein (hsCRP)], insulin signaling [insulin and IGF1], renal function [cystatin], senescence [growth differentiating factor 15 (GDF-15)] and cardiovascular function [N-terminal B-type natriuretic peptides (NT-proBNP)]. Analyses will be by intention-to-treat model.

ETHICS & DISSEMINATION

The study is approved by the Institutional Ethics Committee of Swami Vivekananda Yoga Anusandhana Samsthana University, Bangalore (ID:RES/IEC-SVYASA/242/2022). Written informed consent will be obtained from each participant prior to inclusion.

Online Chair Yoga and Digital Learning for Rural Underserved Older Adults at Risk for Alzheimer's Disease and Related Dementias

OBJECTIVES

We evaluated the feasibility and preliminary efficacy of a home-based online chair yoga (OCY) program for racially and ethnically diverse rural community-dwelling older adults.

METHODS

We randomly assigned participants to OCY or a computer brain game (CBG). After a computer literacy training led by high school students, participants engaged in remotely supervised OCY or CBG in twice-weekly 45-minute sessions for 12 weeks. Outcome data (pain interference, cognitive function, mobility, computer skills) were collected at baseline, post-intervention, and 3-month follow-up.

RESULTS

A total of 32 eligible residents with mean age of 71 years participated in this intervention study. The interventions were feasible (100% recruitment rate, 96.8% retention rate, 100% safety rate). There were significant improvements in pain interference, cognitive function, mobility, and computer skills from baseline to follow-up among participants in both OCY and CBG but no significant differences in outcomes between groups.

CONCLUSIONS

Preliminary results indicated that the CBG was as effective as online OCY in clinical outcomes in these participants. However, this should be confirmed in future studies.

CLINICAL IMPLICATIONS

This telehealth-based intervention is feasible for older adults in rural and digitally underserved communities and could provide a strategy for delivering health-promoting interventions for home-bound older adults at risk for Alzheimer's disease and related dementias (ADRD) and connect caregivers to online resources.

Effect of yoga on adipokine levels among overweight and obese people: A systematic review

BACKGROUND

Adipokines have an important role in the pathophysiology of overweight and obesity and associated inflammatory diseases.

OBJECTIVE

The present review aims to evaluate the role of Yoga on adipokines among people with overweight and obesity.

METHODS

Authors performed a systematic search for relevant research studies as per the PRISMA guidelines in Google Scholar, Medline/Pubmed, Scopus, Web of Science, PsychInfo electronic databases. Two independent authors conducted the selection of articles, data extraction, assessment of the risk of bias for individual studies. Any disagreements were resolved by discussion with the third author.

RESULTS

Eight randomized trials and four uncontrolled trials involving a total of 1054 participants were included. Yoga with varying frequencies was administered for different durations. The studied adipokines among overweight and obese were leptin, adiponectin, interleukin-6 (IL-6), Tumor necrosis factor-alpha (TNF-α), chemerin, visfatin, plasminogen activator inhibitor-1 (PAI-1), and transforming growth factor-beta (TGF-β). The methodological quality of the included studies was low to moderate on the Cochrane risk of bias tool and Newcastle-Ottawa Quality Assessment Scale. The higher the frequency and duration of Yoga practice, the more significant changes in the adipokine levels were seen.

CONCLUSION

The present review indicates that Yoga practices positively impacts adipokines among people with overweight and obesity. However, the present study precludes the generalizability of results due to the methodological heterogeneity, the type of Yoga intervention, and settings.

Feasibility and impact of a remote moderate-intensity yoga intervention on stress and executive functioning in working adults: a randomized controlled trial

The feasibility of a moderate-intensity yoga intervention, delivered remotely via supervised and unsupervised sessions, and its psychosocial and cognitive effects have not been thoroughly investigated. This randomized controlled trial assessed feasibility and preliminary efficacy of an 8-week moderate-intensity yoga intervention (3×/week, 50 min) delivered remotely (vs. a waitlist control arm), on stress and cognitive functioning. Participants (n = 86) were low active, full-time working adults (81.40% female; Mage = 41 years) with symptoms of stress. Feasibility was assessed via adherence, enjoyment, and safety; stress and anxiety via self-report questionnaires; and executive functioning via neuropsychological tests. Overall attendance was 75.1%, 100% of participants enjoyed the intervention, and only one adverse event was reported. At follow-up, the yoga group had significantly lower stress and anxiety, and higher accuracy on working memory tasks. Remote moderate intensity yoga practice proved safe, enjoyable, and may reduce stress and improve cognitive functioning. This study was pre-registered on ClinicalTrials.gov (NCT04740229).

Yoga, aerobic and stretching exercise effects on neurocognition: Randomized controlled trial protocol

As the global population ages, the prevalence of cognitive decline and dementia is expected to rise, creating a significant health and economic burden. The purpose of this trial is to rigorously test, for the first time, the efficacy of yoga training as a physical activity intervention to mitigate age-related cognitive decline and impairment. We are conducting a 6-month randomized controlled trial (RCT) of exercise among 168 middle aged and older adults to compare the efficacy of yoga vs. aerobic exercise on cognitive function, brain structure and function, cardiorespiratory fitness, and circulating inflammatory and molecular markers. Using a single-blind, three arm RCT, 168 older adults ages 55-79 will be assigned to either: a Hatha yoga group, an aerobic exercise group or a stretching-toning active control group. Participants will engage in hour long group exercise 3x/week for 6-months. A comprehensive neurocognitive test battery, brain imaging, cardiovascular fitness test, and a blood draw will take place at baseline; end of the 6-month intervention, and at 12-month follow-up. Our primary outcomes of interest are brain regions, such as hippocampal volume and prefrontal cortex, and cognitive functions, such as episodic memory, working memory and executive functions, that are typically affected by aging and Alzheimer's disease. Not only will this RCT test whether yoga is a means to mitigate age-related cognitive decline, but it may also offer an alternative to aerobic exercise, which could be particularly appealing to older adults with compromised physical functioning. ClinicalTrials.gov Identifier: NCT04323163.

Asynchronous Technologies in Mental Health Care and Education

Purpose of review

Patients, providers, and trainees should understand the current types of asynchronous technologies that can be used to enhance the delivery and accessibility of mental health care. Asynchronous telepsychiatry (ATP) removes the need for real time communication between the clinician and patient, which improves efficiency and enables quality specialty care. ATP can be applied as distinct consultative and supervisory models in clinician-to-clinician, clinician-to-patient, and patient-to-mobile health settings.

Recent findings

This review is based on research literature and the authors' clinical and medical training, using experiences with asynchronous telepsychiatry from before, during, and after the COVID-19 pandemic. Our studies demonstrate that ATP provides positive outcomes in the clinician-to-patient model with demonstrated feasibility, outcomes and patient satisfaction. One author's medical education experience in the Philippines during COVID-19 highlights the potential to utilize asynchronous technology in areas with limitations to online learning. We emphasize the need to teach media skills literacy around mental health to students, coaches, therapists, and clinicians when advocating for mental well-being. Several studies have demonstrated the feasibility of incorporating asynchronous e-tools such as self-guided multimedia and artificial intelligence for data collection at the clinician-to-clinician and patient-to-mobile health level. In addition, we offer fresh perspectives on recent trends in asynchronous telehealth in wellness, applying concepts such as "tele-exercise" and "tele-yoga."

Summary

Asynchronous technologies continue to be integrated into mental health care services and research. Future research must ensure that the design and the usability of this technology puts the patient and provider first.

Effect of Yoga on Frailty in Older Adults : A Systematic Review

BACKGROUND

Yoga, a multicomponent mind-body practice, improves several domains of physical and psychological health and may affect frailty in older adults.

PURPOSE

To evaluate the available trial evidence on the effect of yoga-based interventions on frailty in older adults.

DATA SOURCES

MEDLINE, EMBASE, and Cochrane Central from their inception to 12 December 2022.

STUDY SELECTION

Randomized controlled trials evaluating the effect of yoga-based interventions, including at least 1 session of physical postures, on a validated frailty scale or single-item markers of frailty in adults aged 65 years or older.

DATA EXTRACTION

Two authors independently screened articles and extracted data; 1 author assessed risk of bias with review from a second author. Disagreements were resolved through consensus and as-needed input from a third author.

DATA SYNTHESIS

Thirty-three studies (n = 2384 participants) were identified in varied populations, including community dwellers, nursing home residents, and those with chronic disease. Yoga styles were primarily based on Hatha yoga and most often included Iyengar or chair-based methods. Single-item frailty markers included measures of gait speed, handgrip strength, balance, lower-extremity strength and endurance, and multicomponent physical performance measures; no studies included a validated definition of frailty. When compared with education or inactive control, there was moderate-certainty evidence that yoga improved gait speed and lower-extremity strength and endurance, low-certainty evidence for balance and multicomponent physical function measures, and very low-certainty evidence for handgrip strength.

LIMITATION

Heterogeneity in study design and yoga style, small sample sizes, and reporting deficiencies leading to concerns for selection bias.

CONCLUSION

Yoga may affect frailty markers that are associated with clinically meaningful outcomes in older adult populations but may not offer benefit over active interventions (for example, exercise).

PRIMARY FUNDING SOURCE

None. (PROSPERO: CRD42020130303).

Effects of Yoga and Aerobic Exercise on Verbal Fluency in Physically Inactive Older Adults: Randomized Controlled Trial (FitForAge)

Purpose

To compare the effects on verbal fluency of a supported yoga-based exercise intervention to an aerobic exercise intervention and a wait-list control group.

Participants and Methods

Eighty-two physically-inactive but otherwise healthy adults (mean age 72.5 years, range 65-85, 77% female) were recruited into a 12-week, three-group, parallel randomized controlled trial. Participants were supported to complete ≥3 Hatha yoga classes per/week or ≥3 structured aerobic exercise sessions/week. A wait-list control group continued usual daily activities only. Verbal fluency, including total-FAS, animals, and verbs, was assessed before and after interventions. Group effects were assessed using analysis of covariance (ANCOVA).

Results

Twenty-seven participants were randomized to yoga, 29 to aerobic exercise and 26 to a waitlist. At 12-week follow-up, compared to baseline, there were increases in mean total-FAS in the yoga (+5.0 words, p=0.002) and aerobic exercise groups (+6.6 words, p=0.004). Mean total-FAS in the wait-list control group remained stable (-0.5 words, p=0.838). There were medium-magnitude estimated treatment effects on total-FAS for yoga versus wait-list control and aerobic exercise versus wait-list control: Hedges' g=0.51 (p=0.213) and 0.57 (p=0.098) respectively. In addition, small-to-medium magnitude estimated treatment effects were seen on animals and verbs for yoga versus wait-list control and aerobic exercise versus wait-list control: g=0.28 (p=0.155), 0.19 (p=0.766) and 0.50 (p=0.085), 0.59 (p=0.233) respectively.

Conclusion

Participation in yoga or aerobic exercise was associated with estimated improvements in verbal fluency compared to a non-active control group. Yoga and aerobic exercise may be promising approaches by which to promote cognitive function among older adults.

Resistance Exercise Program in Cognitively Normal Older Adults: CERT-Based Exercise Protocol of the AGUEDA Randomized Controlled Trial

OBJECTIVES

To provide a comprehensive CERT (Consensus on Exercise Reporting Template)-based description of the resistance exercise program implemented in the AGUEDA (Active Gains in brain Using Exercise During Aging) study, a randomized controlled trial investigating the effects of a 24-week supervised resistance exercise program on executive function and related brain structure and function in cognitively normal older adults.

DESIGN AND PARTICIPANTS

90 cognitively normal older adults aged 65 to 80 were randomized (1:1) to a: 1) resistance exercise group; or a 2) wait-list control group. Participants in the exercise group (n = 46) performed 180 min/week of resistance exercise (3 supervised sessions per week, 60 min/session) for 24 weeks.

INTERVENTION

The exercise program consisted of a combination of upper and lower limb exercises using elastic bands and the participant's own body weight as the main resistance. The load and intensity were based on the resistance of the elastic bands (7 resistances), number of repetitions (individualized), motor complexity of exercises (3 levels), sets and rest (3 sets/60 sec rest), execution time (40-60 sec) and velocity (as fast as possible).

SETTINGS

The maximum prescribed-target intensity was 70-80% of the participants' maximum rate of perceived exertion (7-8 RPE). Heart rate, sleep quality and feeling scale were recorded during all exercise sessions. Those in the wait-list control group (n = 44) were asked to maintain their usual lifestyle. The feasibility of AGUEDA project was evaluated by retention, adherence, adverse events and cost estimation on the exercise program.

RESULTS AND CONCLUSIONS

This study details the exercise program of the AGUEDA trial, including well-described multi-language manuals and videos, which can be used by public health professionals, or general public who wish to implement a feasible and low-cost resistance exercise program. The AGUEDA exercise program seems to be feasible by the high retention (95.6%) and attendance rate (85.7%), very low serious adverse event (1%) and low economic cost (144.23 € /participant/24 weeks). We predict that a 24-week resistance exercise program will have positive effects on brain health in cognitively normal older adults.

Impact of Yoga Versus Memory Enhancement Training on Hippocampal Connectivity in Older Women at Risk for Alzheimer's Disease

BACKGROUND

Yoga may be an ideal early intervention for those with modifiable risk factors for Alzheimer's disease (AD) development.

OBJECTIVE

To examine the effects of Kundalini yoga (KY) training versus memory enhancement training (MET) on the resting-state connectivity of hippocampal subregions in women with subjective memory decline and cardiovascular risk factors for AD.

METHODS

Participants comprised women with subjective memory decline and cardiovascular risk factors who participated in a parent randomized controlled trial (NCT03503669) of 12-weeks of KY versus MET and completed pre- and post-intervention resting-state magnetic resonance imaging scans (yoga: n = 11, age = 61.45±6.58 years; MET: n = 11, age = 64.55±6.41 years). Group differences in parcellated (Cole-anticevic atlas) hippocampal connectivity changes (post- minus pre-intervention) were evaluated by partial least squares analysis, controlling for age. Correlations between hippocampal connectivity and perceived stress and frequency of forgetting (assessed by questionnaires) were also evaluated.

RESULTS

A left anterior hippocampal subregion assigned to the default mode network (DMN) in the Cole-anticevic atlas showed greater increases in connectivity with largely ventral visual stream regions with KY than with MET (p < 0.001), which showed associations with lower stress (p < 0.05). Several posterior hippocampal subregions assigned to sensory-based networks in the Cole-anticevic atlas showed greater increases in connectivity with regions largely in the DMN and frontoparietal network with MET than with KY (p < 0.001), which showed associations with lower frequency of forgetting (p < 0.05).

CONCLUSION

KY training may better target stress-related hippocampal connectivity, whereas MET may better target hippocampal sensory-integration supporting better memory reliability, in women with subjective memory decline and cardiovascular risk factors.

The Impact of a Yoga-Based Mindfulness Intervention versus Psycho-Educational Session for Older Adults with Mild Cognitive Impairment: The Protocol of a Randomized Controlled Trial

BACKGROUND

There is a global agreement in the medical community that a significant proportion of dementia cases could be prevented or postponed. One of the factors behind this agreement comes from scientific evidence showing that mind-body interventions such as mindfulness and yoga for the elderly have been related to a range of positive outcomes, including improved cognition performance in seniors with mild cognitive impairment (MCI).

OBJECTIVE

This study aims to evaluate the effectiveness of a yoga-based mindfulness intervention (YBM) versus psychoeducational sessions for older adults with MCI attending Hospital Clinic Universidad de Chile in Santiago.

METHOD

Two-arm, individually randomized controlled trial (RCT) will be carried out at Clinical Hospital Universidad de Chile in Santiago. Older people over 60 years with any type of MCI using a score < 21 in the Montreal Cognitive Assessment (MoCA) test and a score of 0.05 in the Clinical Dementia Rating (CDR) Scale; and with preserved activities of daily living will be randomly assigned with an allocation ratio of 1:1 in either the yoga-based mindfulness intervention or the active control group based on the psycho-educational program. People who have performed yoga and/or mindfulness in the last 6 months or/and people with a psychiatric clinical diagnosis will be excluded from the study. Montreal Cognitive Assessment, the Lawton Instrumental Activities of Daily Living Scale (IADL), the Barthel Index (BI), the Pemberton happiness index, the Geriatric Anxiety Inventory (GAI) as well as the Geriatric Depression Scale (GDS-5) will be administered by blinded outcomes assessors before random assignment (Pre-test), the week following the last session of the intervention (post-test), and then after 3- and 6-months follow-up.

RESULTS

The YBM intervention protocol based on a video recording has been adapted and designed. This is the first RCT to examine the effects of a yoga-based mindfulness intervention in improving cognitive and physical functions and mental health outcomes for Chilean elderly diagnosed with MCI. It is expected to be implemented as an acceptable and effective non-pharmacological option for older people with MCI.

CONCLUSION

Providing evidence-based programs such as preventive therapy for Alzheimer's disease has relevant implications for public mental health services in Chile.

Yoga as an Escape from Depreciating Mental Health due to COVID 19: A Qualitative study analyzing the factors associated with mental status based on the experiences of geriatric population's participation in an Online program during COVID 19 lockdown in India

Introduction

The COVID-19 pandemic has left an array of direct physical consequences unevenly on the elderly apart from leaving a wide range of indirect consequences of mental health problems on them. This study aims to understand the effect of a Yoga-Meditation based mobile phone application intervention to reduce the duress by mental health issues via a qualitative analysis.

Methods

A phenomenological qualitative succession of an explanatory sequential design of a prior quantitative study followed by a Yoga-Meditation mobile phone based intervention, where 30 participants who had mild or moderate Depression, Anxiety or Stress as assessed by DASS-21 were chosen by random sampling and were asked to take part in an interview. The interview was transcribed, coded, patterns identified and themes were created to understand the perceptions.

Results

Three major schools of thought were identified and explored to understand the general perception of Mental health, COVID-19 and the intervention: a) Knowledge Axis patterns of COVID-19, which included their prior knowledge about the disease, its consequences and their cues to action based on those beliefs, b) Mental Health and Strategies to Positivity, involves all their actions to promote, restore or propagate a positive mental attitude from religious activities to physical activities and c) Application related thoughts, involved their perceptions of the app, the barriers to use and suggestions to improve.

Conclusion

This study gave deeper insight into the schools of thought which will be important in designing future interventions and yoga-meditation based programs in the future, essentially for geriatric populations as it serves as a feasible simple measure for the same.

Yoga Prevents Gray Matter Atrophy in Women at Risk for Alzheimer's Disease: A Randomized Controlled Trial

BACKGROUND

Female sex, subjective cognitive decline (SCD), and cardiovascular risk factors (CVRFs) are known risk factors for developing Alzheimer's disease (AD). We previously demonstrated that yoga improved depression, resilience, memory and executive functions, increased hippocampal choline concentrations, and modulated brain connectivity in older adults with mild cognitive impairment.

OBJECTIVE

In this study (NCT03503669), we investigated brain gray matter volume (GMV) changes in older women with SCD and CVRFs following three months of yoga compared to memory enhancement training (MET).

METHODS

Eleven women (mean age = 61.45, SD = 6.58) with CVRF and SCD completed twelve weeks of Kundalini Yoga and Kirtan Kriya (KY + KK) while eleven women (mean age = 64.55, SD = 6.41) underwent MET. Anxiety, resilience, stress, and depression were assessed at baseline and 12 weeks, as were T1-weighted MRI scans (Siemens 3T Prisma scanner). We used Freesurfer 6.0 and tested group differences in GMV change, applying Monte-Carlo simulations with alpha = 0.05. Region-of-interest analysis was performed for hippocampus and amygdala.

RESULTS

Compared to KY + KK, MET showed reductions in GMV in left prefrontal, pre- and post-central, supramarginal, superior temporal and pericalcarine cortices, right paracentral, postcentral, superior and inferior parietal cortices, the banks of the superior temporal sulcus, and the pars opercularis. Right hippocampal volume increased after yoga but did not survive corrections.

CONCLUSION

Yoga training may offer neuroprotective effects compared to MET in preventing neurodegenerative changes and cognitive decline, even over short time intervals. Future analyses will address changes in functional connectivity in both groups.

Complementary and Integrative Medicine for Neurocognitive Disorders and Caregiver Health

PURPOSE OF REVIEW

Integrative medicine is the practice of combining conventional medical treatments with "alternative" or "complementary" therapies. Integrative psychiatry is a holistic, person-centered approach to neuropsychiatric disorders that emphasizes a person's physical, emotional, interpersonal, behavioral, nutritional, environmental, and spiritual dimensions to achieve well-being. Older adults are more prone to physical injury, interpersonal loss, chronic illnesses, and physical and cognitive decline that can manifest as anxiety, depression, with functional decline and inability to care for self. Additionally, stress of caring for older adults with dementia can adversely affect caregivers' health. Although integrative approaches are perceived as safer and less stigmatizing, it is important to understand the risks and benefits of such therapies for older adults with neurocognitive disorders and their caregivers.

RECENT FINDINGS

Here, we summarize the results of the recent clinical trials and meta-analyses that provide evidence for integrative approaches to treating older adults with cognitive disorders and their caregivers which include the use of diet and supplements, and mind-body therapies. Dietary and mind-body therapies have become increasingly popular and show the strongest evidence of effectiveness for cognitive disorders and caregiver stress. Vitamins and supplements are the most popular integrative intervention, but there is mixed evidence supporting their use and the concern for herb (supplement)-drug interactions. While there is increasing popularity of integrative treatments, information to guide clinicians providing care for older adults remains limited, with variable scientific rigor of the available RCTs for a large number of commonly used integrative interventions particularly for cognitive disorders and caregiver stress and well-being.

Effects of Aerobic Exercise and Mind-Body Exercise in Parkinson's Disease: A Mixed-Treatment Comparison Analysis

Background/Objectives: Aerobic exercise and mind-body exercise, are vital for improving motor and non-motor functional performance of Parkinson's disease (PD). However, evidence-based recommendations on which type of exercise is most suitable for each individual are still lacking. Therefore, we conduct a network meta-analysis to assess the relative efficacy of aerobic and mind-body exercise on motor function and non-motor symptoms in Parkinson's disease and to determine which of these therapies are the most suitable. Design: A network meta-analysis and dose-response analysis. Setting and Participants: Medline, Embase (all via Ovid), and the Cochrane Central Register of Controlled Trials were comprehensively searched for related trials through April 2021. Measurements: Study quality was evaluated using the Cochrane Risk of Bias Tool. The effect sizes of continuous outcomes were calculated using mean differences (MDs) or standardized mean differences (SMDs). A network meta-analysis with a frequentist approach was conducted to estimate the efficacy and probability rankings of the therapies. The dose-response relationship was determined based on metaregression and SUCRA. Results: Fifty-two trials with 1971 patients evaluating six different therapies were identified. For the UPDRS-motor score and TUG score, yoga all ranked highest (SUCRA = 92.8%, 92.6%, respectively). The SUCRA indicated that walking may best improve the BBS score (SUCRA = 90.2%). Depression, cognitive and activities of daily living scores were significantly improved by yoga (SUCRA: 86.3, 95.1, and 79.5%, respectively). In the dose-response analysis, 60-min sessions, two times a week might be the most suitable dose of yoga for reducing the UPDRS-motor score of PD patients. Conclusion: Yoga and walking are important options for increasing functional mobility and balance function, and yoga might be particularly effective for decreasing depressive symptoms and cognitive impairment and improving activities of daily living in PD. The potential optimal dose of yoga for enhancing motor ability in PD patients is 60-min sessions, two times a week. Registration: PROSPERO CRD42021224823.

Meta-Analysis of the Effect of Yoga Practice on Physical Fitness in the Elderly

The purpose of this study was to meta-analyze the effects of yoga intervention on physical fitness in the elderly. The following databases were systematically searched in 25 March 2021: Cochrane, PubMed and Embase. A total of 656 papers was identified through key word combinations, finally, 12 studies were included in the meta-analysis. The main conclusions are as follows. First, yoga practice showed moderately positive effects on muscle strength, balance, mobility, and lower body flexibility, but had no significant effect on cardiorespiratory endurance and upper body flexibility. Second, sub-group analysis showed that subjects in their 60s and 70s and yoga practice for 9–12 weeks had a large positive effect on physical fitness. Yoga is a multimodal activity that improves muscle strength, balance, and flexibility in the elderly, and physical activity policies should continue to promote yoga as an activity that enhances physical and mental wellbeing in this population.

Depression, combined visual and hearing impairment (dual sensory impairment): a hidden multi-morbidity among the elderly in Residential Care in India

To report the prevalence of depression and its association with combined visual (VI) and hearing impairment (HI) in the elderly in residential care in India. Participants aged ≥ 60 years were recruited from 41 homes. Data on personal and sociodemographic information were obtained. Visual acuity was measured using the logMAR chart. Patient Health Questionnaire (PHQ-9) was used to assess depression, and the Hearing Handicap Inventory for the Elderly Screening (HHIE) was administered to assess hearing status. Data of all 867 eligible elderly participants were analysed. The mean age of the participants was 74.2 years (standard deviation: 8.2 years) and included 537 (61.9%) women and 117 (13.5%) participants who had no education. The prevalence of depression was 60.0% (95% CI: 45.2-73.4) in the elderly with combined VI and HI compared to 20.9% (95% CI:14.4-28.8) among those with VI only and 37.8% (95% CI: 26.6-46.5) among those with HI only. On multiple logistic regression analyses, depression was approximately 5 times higher among the participants with DSI after adjusting for other covariates. Six out of ten elderly with combined HI and VI had depression highlighting the need for screening and referral when elderly present with combined vision and hearing loss.
