Quality of Life Assessment in Older Adults with Dementia: A Systematic Review

Quality of Life in Mild Cognitive Impairment and Mild Dementia Associated with Alzheimer's Disease: A Systematic Review

Mild cognitive impairment (MCI) and Alzheimer's disease (AD) have a profound impact on patients' quality of life (QoL), with progressive declines occurring as the disease advances. This systematic review aims to summarize the published evidence on patient-reported outcomes (PROs) in individuals with MCI due to AD and mild AD dementia. Comprehensive searches were conducted across five major databases to identify studies reporting on utility values, disutilities, and QoL measures in these patient populations. A total of 23 studies were included that utilized various QoL assessment tools, including EQ-5D (n = 14), SF-36/SF-12 (n = 4), and QOL-AD (n = 11). Reported EQ-5D scores ranged from 0.81 to 0.92 for patients with MCI and from 0.67 to 0.85 for those with mild AD, indicating a noticeable decline in QoL as the disease progresses. QOL-AD scores ranged from 33.8 to 42.5 for MCI and from 32.4 to 38.1 for mild AD, equally reflecting the greater impairment in QoL with disease advancement. Interventions were generally associated with smaller declines in PROs compared to placebo, suggesting a positive impact of treatment in mitigating QoL deterioration. The findings underscore the significant QoL differences between MCI and mild AD, emphasizing the potential benefit of early intervention to preserve QoL and delay disease progression. This review highlights the importance of continued research to better understand QoL in patients with MCI and mild AD dementia, particularly in terms of capturing comprehensive patient-reported outcomes and evaluating the effectiveness of interventions over time. These findings can contribute to a more informed approach in clinical practice and support decision-making in the management of early-stage AD.

Validation of the Chinese Version of Quality of Life Instrument (QUALIDEM-C) for People With Dementia in Long-Term Care Home

OBJECTIVES

To validate and examine the psychometric properties of the Chinese version of QUALIDEM (QUALIDEM-C).

METHODS

The psychometric properties of the Chinese QUALIDEM were tested in a sample of 150 residents in long-term care homes. Concurrent validity, internal consistency, inter-rater reliability, test-retest reliability and factor structure were determined.

RESULTS

QUALIDEM-C demonstrated good semantic equivalence with original version and good content validity. QUALIDEM-C showed satisfactory internal consistency (Cronbachs' alpha = 0.895), inter-rater reliability (ICC = 0.970) and test-retest reliability (ICC = 0.942). Acceptable concurrent validity was showed by consistently moderate correlations of QUALIDEM-C with generic and disease specific quality of life measures.

CONCLUSIONS

QUALIDEM-C is reliable and valid scales to measure quality of life of residents in long-term care home. Its applicability across residents with different levels of cognitive function favors its use over other measures in this context. It is potentially an effective tool, rather by multiple measures, to evaluate quality of life in future long-term care home research.

Deep into Cognition: The Neuropsychological Identikit of Younger and Older Individuals after COVID-19 Infection

The literature on COVID-19 continues to increase daily. Cognitive sequelae associated with COVID-19 infection still draw the attention of the scientific community given the lack of consensus about their existence, etiology, characterization and reversibility. The aim of this study is to provide a neuropsychological identikit for younger (<65 years) and older (≥65 years) individuals diagnosed with COVID-19 infection, at baseline and after 3 and 6 months. In total, 226 individuals took part in a retrospective observational study and their cognitive performance was compared across groups (younger adults vs. older adults) and time (T0, T1, T2). The results highlighted differences between younger and older adults in the Montreal Cognitive Assessment (MoCA) global score, as expected in consideration of the different physiological conditions of the two populations. However, memory performance highlighted the two groups as characterized by a difference in patterns of recall that may move beyond a physiological explanation and provide information about COVID-19 cognitive sequelae. This study suggests that cognitive deficits observed in COVID-19 survivors may reflect a difficulty in attention and concentration that interferes mainly with retrieval processes. This result fits well with the concept of "brain fog" typical of post-COVID-19 syndrome and may also reflect the stress experienced while facing the pandemic.

Cardiovascular health, measured using Life's Essential 8, is associated with reduced dementia risk among older men and women

BACKGROUND

Dementia poses considerable challenges to healthy aging. Prevention and management of dementia are essential given the lack of effective treatments for this condition.

METHODS

A secondary data analysis was conducted using data from 928 InCHIANTI study participants (55% female) aged 65 years and older without dementia at baseline. Cardiovascular health (CVH) was assessed by the "Life's Essential 8" (LE8) metric that included health behaviors (diet, physical activity, smoking status, sleep duration) and health factors (body mass index, blood lipid, blood glucose, blood pressure). This new LE8 metric scores from 0 to 100, with categorization including "low LE8" (0-49), indicating low CVH, "moderate LE8 (50-79)", indicating moderate CVH, and "high LE8 (80-100)", indicating high CVH. Dementia was ascertained by a combination of neuropsychological testing and clinical assessment at each follow-up visit. Cox proportional hazards models were used to examine associations between CVH at baseline and risk of incident dementia after a median follow-up of 14 years.

RESULTS

Better CVH (moderate/high LE8 vs. low LE8) was inversely associated with the risk of incident dementia (hazard ratio [HR]: 0.61, 95% confidence interval [CI]: 0.46-0.83, p = 0.001). Compared with health factors, higher scores of the health behaviors (per 1 standard deviation [SD]), specifically weekly moderate-to-vigorous physical activity time (per 1 SD), were significantly associated with a lower risk of incident dementia (health behaviors: HR:0.84, CI:0.73-0.96, p = 0.01; physical activity: HR: 0.62, CI: 0.53-0.72, p < 0.001).

CONCLUSION

While longitudinal studies with repeated measures of CVH are needed to confirm these findings, improving CVH, measured by the LE8 metric, may be a promising dementia prevention strategy.

The association of the comorbidity status of metabolic syndrome and cognitive dysfunction with health-related quality of life

PURPOSE

Both metabolic syndrome (MetS) and cognitive dysfunction impair health-related quality of life (HRQOL). This study aims to determine whether individuals experiencing both MetS and cognitive dysfunction have lower HRQOL.

METHODS

This cross-sectional study enrolled 567 participants who attended outpatient clinics at a medical center in northern Taiwan. MetS was diagnosed according to the modified criteria for the Asian population. Cognitive function was categorized as normal, mild cognitive dysfunction, and advanced cognitive dysfunction according to the score of the Montreal Cognitive Assessment, Taiwanese version. HRQOL was assessed using the SF-36v2® Health Survey (SF-36v2). The associations of the comorbidity status of MetS and cognitive dysfunction with HRQOL were analyzed using linear regression models, adjusting for age, sex, marital status, education level, income groups, and activities of daily living.

RESULTS

Out of 567 participants, 33 (5.8%) had MetS with mild cognitive dysfunction, and 34 (6.0%) had MetS with advanced cognitive dysfunction. Participants with both MetS and advanced cognitive dysfunction exhibited the lowest scores in the physical component summary and almost all scales of HRQOL. MetS exacerbated the inverse association between mild cognitive dysfunction and the mental component summary. For those with MetS, the scores on scales of role physical, bodily pain, vitality, and social functioning worsened as cognitive function deteriorated (all Ptrend<0.05).

CONCLUSION

As the severity of comorbidity between MetS and cognitive dysfunction varies, patients exhibited poorer performance in different aspects of HRQOL. Future research is needed to find solutions to improve HRQOL for patients with both MetS and cognitive dysfunction.

Determinants of quality of life in French nursing home residents across cognitive levels: a comparative study using convergent mixed-methods

BACKGROUND

The quality of life (QoL) of nursing home residents is multifaceted and influenced by relationships, health, and activities, as per research in international literature. However, studies exploring QoL predictors considering varying cognitive impairment levels are limited in the French context. This study examined the impact of sociodemographic factors and cognitive impairment on the QoL in Alzheimer's Disease Nursing Homes (QoL-AD NH) scale scores among French nursing home residents. It further identified predictors through responses to qualitative semi-structured interviews. These elements were integrated and compared to understand more comprehensively the multifaceted determinants influencing residents' QoL.

METHODS

This mixed methods study used a cross-sectional convergent design, and quantitative and qualitative studies were carried out simultaneously. Using a generalised linear model and Kruskal-Wallis tests, the quantitative strand (N = 151) measured QoL with the QoL-AD NH scale and examined sociodemographic predictors of QoL. The qualitative strand (N = 78) involved semi-structured interviews with residents across four levels of cognitive functioning (no, mild, moderate, and severe impairment) and explored their QoL determinants through thematic analysis. Both strands were then integrated and analysed.

RESULTS

Mild cognitive impairment and depression negatively predicted QoL-AD NH scores. For specific items, residents with mild cognitive impairment had lower "Ability to keep busy daily" and "Current life in general" scores than residents without cognitive impairment. Qualitatively, family relationships were indispensable for QoL across groups, but those with mild cognitive impairment complained about a lack of activities in nursing homes. The analysis identified convergent predictors and enriched our understanding of daily occupation. Theory comparisons revealed assessment limitations in psychological well-being.

CONCLUSIONS

A mixed approach provided a nuanced understanding of QoL, highlighting vulnerable groups and areas for improving assessment. Combining the results from standardised instruments with semi-structured interviews allowed us to capture a fuller range of experiences. The findings suggest a need to reconsider QoL assessment tools for nursing home residents and policies to address their needs regardless of their cognitive levels. They highlight the value of mixed methods for researching this multifaceted field.

Psychometric of the Persian version of Quality of Life in Late-Stage Dementia (QUALID) in the elderly with Alzheimer's disease

BACKGROUND

Improving the quality of life (QoL) is a significant healthcare priority, and it is an important health outcome for elderly individuals with Alzheimer's disease. Quality of Life in Late-Stage Dementia (QUALID) is a specific scale used to measure the QoL in elderly individuals with Alzheimer's. So far, limited quantitative research has been conducted on the psychometric properties of this scale.

AIMS

This study was conducted to translate the QUALID Scale into Persian and evaluate its psychometric properties among family and professional caregivers of elderly individuals with Alzheimer's disease in Tehran.

METHODS

A cross-sectional methodological study was conducted among family and professional caregivers of elderly individuals with Alzheimer's in Tehran, Iran in 2022. The questionnaire was translated into Persian using the forward-backward method. Face and content validity were assessed. Additionally, construct validity was examined using exploratory factor analysis (EFA) with Equamax rotation (n=210) and confirmatory factor analysis (CFA) (n=155). Cronbach's alpha and interclass correlation coefficient (ICC) were estimated to determine reliability.

RESULTS

A total of 365 caregivers with a mean age of 14.18±42.60 years participated in this study. In the face and content validity phase, all 11 items were retained. To determine the construct validity, two factors were extracted in the EFA phase, including behavioural signs of discomfort and behavioural signs of social interaction. The findings of the CFA also indicated that all goodness of fit indices supported the final model. The Cronbach's alpha was excellent for both factors (0.814), and the ICC was calculated as 0.98.

CONCLUSION

Based on the findings of this study, it can be concluded that the Persian version of the QUALID Scale has sufficient validity and reliability for measuring the QoL in elderly Iranian individuals with Alzheimer's.

Strategies to improve end-of-life decision-making and palliative care following hip fracture in frail older adults: a scoping review

BACKGROUND

Although surgery is the gold standard following a hip fracture, the potential for rehabilitation and survival rates are low in frail older patients. Some patients may derive more benefit from palliative care. The objectives of this review were to identify the available strategies to improve end-of-life decision-making and palliative care for frail patients with hip fractures and to synthetise their level of support.

METHODS

We conducted a scoping review of the scientific and grey literature, searching seven databases and websites of associations. We included all study designs, expert opinion articles and clinical practice guidelines (CPGs). Data were synthetised according to the Approach to Patient with Limited Life Expectancy and Hip Fracture framework. The number of research items and their level of evidence were tabulated for each of the recommended strategies.

RESULTS

Of the 10 591 items identified, 34 were eligible. The majority of included articles were original research studies (n = 15). Half of the articles and CPGs focused on intervention categories (55%) such as goals of care discussion and comfort care, followed by factors to consider in the end-of-life decision-making process (25%) and prognosis assessments (20%), mainly through the estimation of life expectancy. The level of evidence for these strategies remains low, given the limited number of prospective studies supporting them.

CONCLUSIONS

This scoping review highlighted that end-of-life care in frail older patients with a hip fracture remains understudied. The strategies identified could be prioritised for future research to improve the well-being of the target population while promoting sustainable resource management.

Impact of Care-Recipient Relationship Type on Quality of Life in Community-Dwelling Older Adults With Dementia Over Time

INTRODUCTION

Maintaining quality of life (QoL) has been identified as the primary goal of care services for person living with dementia (PLWD).

METHODS

A secondary analysis was conducted on five rounds of the National Health and Aging Trends Study (NHATS) over 4 years. A generalized estimating equation (GEE) was used to examine the prediction of relationship type on older adults' QoL through four domains: mental health, general health, functional limitations, and pain.

RESULTS

older adults cared for by an adult-child or multiple caregivers predicted increased risk for functional limitations after adjustment for their socio-demographic and dementia status (IRR = 1.53, CI [1.26, 1.86]; IRR = 1.36, CI [1.14, 1.61], respectively). The interaction between the relationship type and education was significant. Older adults with a high school education or below, who were cared for by an adult child, had a significantly higher risk of increasing functional limitations over 4 years compared to those cared for by a spouse/partner (contrast = .50, P = .01, 95% CI [.07, .93]; contrast=.52, P = .03, 95% CI [.03, 1.02]; respectively). Similarly, older adults with a high school education, who were cared for by multiple caregivers, also experienced a significantly higher risk of increasing functional limitations than those cared for by a spouse/partner (contrast = .44, P = .03, 95% CI [.02, .85]).

CONCLUSION

Our findings provide evidence of the significant contribution of relationship type on PLWD's QoL changes over time. They also help to prioritize resource allocation while addressing PLWD's demands by socio-demographics such as education level.

Technology-based group exercise interventions for people living with dementia or mild cognitive impairment: A scoping review

Older people living with dementia or mild cognitive impairment (MCI) are more vulnerable to experiencing social isolation and loneliness due to their cognitive and physical impairments. Increasingly integrating technology into group exercises contributed to the improved resilience and well-being of older adults living with dementia and MCI. The purpose of this scoping review was to identify the various types, feasibility, outcome measures, and impacts of technology-based group exercise interventions for people with dementia or MCI. We utilized the Joanna Briggs Institute approach, a three-step process. A comprehensive literature search on five databases-CINAHL, MEDLINE, Embase, Web of Science, and PsycInfo-until January 2024 yielded 1,585 publications; the final review included 14 publications that recruited a total of 379 participants, with mean age of 69 (SD = 4.21) years to 87.07 (SD = 3.92) years. Analysis of data showed three types of technology-based group exercise interventions for people with dementia or MCI: (a) exergames, (b) virtual cycling or kayak paddling, and (c) video-conferencing platforms. In addition, we identified three key impacts: (a) feasibility and accessibility; (b) physical, psychosocial, and cognitive benefits; and (c) adaptations necessary for persons with dementia or MCI. Our study suggests that technology-based group exercise interventions are feasible and acceptable to persons with dementia or MCI. Future studies should involve individuals with dementia and their caregivers in the design and implementation of technology-based group exercise programs.

Person-centered care as a tool to reduce behavioral and psychological symptoms in older adults with dementia living in residential care facilities

Among older adults living in dementia residential care facilities (RCF) behavioral and psychological symptoms (BPSD) are common, affecting the quality of life (QOL) for the residents as well as being challenging for the staff. The person-centered care (PCC) approach addresses BPSD by giving trained staff mandate to focus on the relation and to adapt the encounter and the environment to increase QoL for the person with dementia. The aims with this study were to improve PCC, decrease BPSD and improve QOL among older persons with dementia living in RCFs, and to explore leaders' and healthcare staff's experiences of a PCC intervention. An educational program was implemented at two RCFs. Data was collected through questionnaires, from national quality registries and through focus group interviews. A significant increase in PCC and QOL at three months was seen. However, no significant difference in BPSD was seen. The interviews showed the importance of a trust-based relationship, and support from an active management to improve PCC, as well as changing old patterns and recognising competence among staff. Factors that affect implementation of PCC in RCF are discussed in the article.

The Delivery of Person-Centered Care for People Living With Dementia in Residential Aged Care: A Systematic Review and Meta-Analysis

BACKGROUND AND OBJECTIVES

Person-centered care is the gold standard of care for people living with dementia, yet few systematic reviews have detailed how it is delivered in practice. This mixed-methods review aimed to examine the delivery of person-centered care, and its effectiveness, for people living with dementia in residential aged care.

RESEARCH DESIGN AND METHODS

A systematic review and meta-analysis. Eligible studies were identified across 4 databases. Quantitative and qualitative studies containing data on person-centered care delivered to people with dementia living in residential aged care were included. Meta-analysis using a random-effects model was conducted where more than 3 studies measured the same outcome. A narrative meta-synthesis approach was undertaken to categorize verbatim participant quotes into representative themes. Risk of bias was undertaken using quality appraisal tools from the Joanna Briggs Institute.

RESULTS

41 studies were identified for inclusion. There were 34 person-centered care initiatives delivered, targeting 14 person-centered care outcomes. 3 outcomes could be pooled. Meta-analyses demonstrated no reduction in agitation (standardized mean difference -0.27, 95% confidence interval [CI], -0.58, 0.03), improvement in quality of life (standardized mean difference -0.63, 95% CI: -1.95, 0.70), or reduced neuropsychiatric symptoms (mean difference -1.06, 95% CI: -2.16, 0.05). Narrative meta-synthesis revealed barriers (e.g., time constraints) and enablers (e.g., staff collaboration) to providing person-centered care from a staff perspective.

DISCUSSION AND IMPLICATIONS

The effectiveness of person-centered care initiatives delivered to people with dementia in residential aged care is conflicting. Further high-quality research over an extended time is required to identify how person-centered care can be best implemented to improve resident outcomes.

Family Caregiving of Patients With Heart Failure and Vascular Dementia in Rural Appalachia: A Mixed-Methods Study

INTRODUCTION

Vascular dementia and heart failure (HF) are common co-existing conditions among adult populations. Each condition requires extensive home caregiving from family caregivers, especially those in rural Appalachia. This study aimed to assess caregivers' burden and their physical and mental health status, as well as explore their experiences and needs.

METHODS

This study used an exploratory mixed-methods design combining quantitative and qualitative research (N = 20 caregivers). We collected data using questionnaires, short-answered interviews, and focus group discussions. The multivariable generalized linear model (GLiM) was used to analyze quantitative data; content analysis was used for qualitative data.

RESULTS

The average age of family caregivers was 64.95 years. The generalized linear model showed that the caregiving burden was associated with caregivers' depression/anxiety (r = 0.68, P < .001) and their number of dementia caregiving years (r = 0.54, P < .05). Caregivers' poor physical health status was associated with better preparedness for HF and dementia home caregiving (r = 0.52, P < .05) and male caregivers (r = -0.46, P < .01). Caregivers' mental health status was associated with depression/anxiety (r = -0.80, P < .001). The qualitative data identified key caregiving themes: emotional impact and physical demands of caregiving, lack of help in rural areas, dealing with multiple disease progression, and relationship changes with their loved ones.

CONCLUSION

Caregiving burden was associated with caregivers' home care responsibilities and the need for support. Nurse-led home caregiving preparedness interventions tailored for family caregivers of patients with HF and dementia in rural areas are recommended.

Unique transcriptional signatures correlate with behavioral and psychological symptom domains in Alzheimer's disease

Despite the significant burden, cost, and worse prognosis of Alzheimer's disease (AD) with behavioral and psychological symptoms of dementia (BPSD), little is known about the molecular causes of these symptoms. Using antemortem assessments of BPSD in AD, we demonstrate that individual BPSD can be grouped into 4 domain factors in our cohort: affective, apathy, agitation, and psychosis. Then, we performed a transcriptome-wide analysis for each domain utilizing bulk RNA-seq of post-mortem anterior cingulate cortex (ACC) tissues. Though all 4 domains are associated with a predominantly downregulated pattern of hundreds of differentially expressed genes (DEGs), most DEGs are unique to each domain, with only 22 DEGs being common to all BPSD domains, including TIMP1. Weighted gene co-expression network analysis (WGCNA) yielded multiple transcriptional modules that were shared between BPSD domains or unique to each domain, and NetDecoder was used to analyze context-dependent information flow through the biological network. For the agitation domain, we found that all DEGs and a highly associated transcriptional module were functionally enriched for ECM-related genes including TIMP1, TAGLN, and FLNA. Another unique transcriptional module also associated with the agitation domain was enriched with genes involved in post-synaptic signaling, including DRD1, PDE1B, CAMK4, and GABRA4. By comparing context-dependent changes in DEGs between cases and control networks, ESR1 and PARK2 were implicated as two high-impact genes associated with agitation that mediated significant information flow through the biological network. Overall, our work establishes unique targets for future study of the biological mechanisms of BPSD and resultant drug development.

Do physical fitness and cognitive function mediate the relationship between basic activities of daily living and quality of life in older adults with dementia?

PURPOSE

Independence in activities of daily living (ADLs) is associated with quality of life (QoL) in individuals with dementia. However, the contribution of physical and cognitive functions to this relationship needs further examination. This study aims to examine the mediating effect of physical fitness and cognitive function in the relationship between independence in basic ADLs and QoL among older adults with dementia.

METHODS

This cross-sectional study included 107 older adults with dementia (74.8% women; age 78.21 ± 7.70 years). Independence in basic ADL and QoL were evaluated using the Barthel Index (BI) and QoL- Alzheimer's Disease Scale, respectively. The Alzheimer's Disease Assessment Scale-Cognitive Subscale and the Mini-Mental State Examination were applied to assess cognitive function. Physical fitness was evaluated using the 30-s chair stand, 2-min step and the Timed-Up and Go tests. A structural equation modelling (SEM) with bootstrapping estimation was conducted to determine the relationship between all variables.

RESULTS

Independence in basic ADL positively affected QoL and this association was mediated by physical fitness (β = 0.242, p = 0.011). No statistically significant results were observed when testing cognitive function as a mediator between BI and QoL (β = 0.009, p = 0.345).

CONCLUSIONS

Physical fitness (i.e., lower body strength, aerobic capacity, and mobility) plays a role in the relationship between basic ADL independence and QoL of older adults with dementia, reinforcing the need to improve and monitor these parameters throughout the disease progression. Future longitudinal studies should explore the temporal relationship between physical and cognitive function and its contribution to basic ADL independence and QoL.

Highly Superior Autobiographical Memory (HSAM): A Systematic Review

Individuals possessing a Highly Superior Autobiographical Memory (HSAM) demonstrate an exceptional ability to recall their own past, excelling most when dates from their lifetime are used as retrieval cues. Fully understanding how neurocognitive mechanisms support exceptional memory could lead to benefits in areas of healthcare in which memory plays a central role and in legal fields reliant on witnesses' memories. Predominantly due to the rareness of the phenomenon, existing HSAM literature is highly heterogenous in its methodologies used. Therefore, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we performed the first systematic review on this topic, to collate the existing behavioural, neuroanatomical, and functional HSAM data. Results from the 20 experimental selected studies revealed that HSAM is categorised by rapidly retrieved, detailed and accurate autobiographical memories, and appears to avoid the normal aging process. Functional neuroimaging studies showed HSAM retrieval seems characterised by an intense overactivation of the usual autobiographical memory network, including posterior visual areas (e.g., the precuneus). Structural neuroanatomical differences do not appear to characterise HSAM, but altered hippocampal resting-state connectivity was commonly observed. We discuss theories of HSAM in relation to autobiographical encoding, consolidation, and retrieval, and suggest future directions for this research.

Developing a framework of concerns from people living with frailty, for the Measure Yourself Concerns and Wellbeing (MYCaW) person-centred outcome measure

INTRODUCTION

Measure Yourself Concerns and Wellbeing is a validated person-centred outcome measure, piloted as a core monitoring tool to understand what matters to people living with frailty in Gloucestershire. This paper describes the acceptability of MYCaW used in this setting, and the development of a framework for analysing personalised concerns from people living with frailty.

METHODS

MYCaW was implemented in the Complex Care at Home service and South Cotswold Frailty Service from November 2020 onwards. MYCaW was completed at the person's first meeting with a community matron and then 3 months later. Nineteen staff completed an anonymous survey to provide feedback on the acceptability of the tool. A framework of concerns bespoke to people living with frailty was created via iterative rounds of independent coding of 989 concerns from 526 people. The inter-rater reliability of the framework was determined by using the Cronbach alpha test.

RESULTS

MYCaW was simple to use and helped health professionals' discussions to be patient focused. A pictorial scale accompanying the Numerical Rating Scale was developed and tested to help people engage with scoring their concerns and well-being more easily. A framework of concerns from people living with frailty was produced with five main supercategories: Mental and Emotional Concerns; Physical Concerns; Healthcare and Service Provision Concerns, Concerns with General Health and Well-being and Practical Concerns. Inter-rater reliability was kappa=0.905.

CONCLUSIONS

MYCaW was acceptable as a core monitoring tool for people living with frailty and enabled a systematic approach to opening 'What Matters to Me' conversations. The personalised data generated valuable insights into how the frailty services positively impacted the outcomes for people living with frailty. The coding framework demonstrated a wide range of concerns-many linked to inequalities and not identified on existing outcome measures recommended for people living with frailty.

Health-Related Quality of Life among Older Adults with Dementia Living in Vietnamese Nursing Homes

Better understanding of the quality of life among nursing home residents with dementia is important for developing interventions. The objectives of this cross-sectional study were to examine factors associated with poor health-related quality of life in older people with dementia living in nursing homes in Hanoi, Vietnam. In-person interviews were conducted with 140 adults who were 60 years and older with dementia, and information about their quality of life was obtained using the Quality of Life in Alzheimer's Disease (QOL-AD) scale. The sociodemographic and clinical factors associated with poor health-related quality of life (lowest quartile) were assessed through the results of physical tests, interviews with nursing home staff, and review of medical records. The average age of the study sample was 78.3 years, 65% were women, and their average QOL-AD total score was 27.3 (SD = 4.4). Malnutrition, total dependence in activities of daily living, and urinary incontinence were associated with poor quality of life after controlling for multiple potentially confounding factors. Our findings show that Vietnamese nursing home residents with dementia have a moderate total quality of life score, and interventions based on comprehensive geriatric assessment remain needed to modify risk factors related to poor health-related quality of life.

Palliative Care in the Ageing European Population: A Cross-Country Comparison

With Europe's ageing population and rising demand for palliative care, it is crucial to examine the use of palliative care among older adults during their last years of life and understand the factors influencing their access and end-of-life circumstances. This study employed a cohort of SHARE participants aged 65 years or older who had passed away between Wave 6 (2015) and Wave 7 (2017). Information on death circumstances, palliative care utilization, and associated variables were analysed. The study revealed that nearly 13.0% of individuals across these countries died under palliative care, with Slovenia having the lowest rate (0.3%) and France the highest (30.4%). Palliative care utilization in the last 30 days before death was observed in over 24.0% of participants, with the Czech Republic having the lowest rate (5.0%) and Greece the highest (48.8%). A higher risk of using or dying in palliative care was significantly associated with cognitive impairment (low verbal fluency), physical inactivity, and good to excellent self-perceived health. This work highlights the urgent need for enhanced global access to palliative care and advocates for the cross-country comparison of effective practices within Europe, tailored to the unique healthcare needs of older adults.

The psychological impact of the COVID-19 pandemic on children/adolescents with ASD and their family environment: a systematic review

The main objective of the review is to analyze the impact of the pandemic in children/teenagers with Autism spectrum disorder (ASD) and in their family environment. An electronic search was carried out in different databases (PsycInfo, Web of Science and Scopus) in order to find publications associated with the aim of this project. The search terms used were derived from the combination of the following search string: "((Pandemic OR Epidemic OR Outbreak OR COVID-19 OR Coronavirus) AND (Children OR Adolescents OR Youth OR Child OR Teenager) AND (Autism OR ASD OR Autism Spectrum Disorder))''. In total, 21 articles were included in this review. The findings of the different investigations included in this review show that the pandemic has produced a negative psychological impact in children/teenagers with ASD. Therefore, long-term follow-up studies should be carried out with the objective of creating effective interventions to treat this problematical.

Association Between Self- and Proxy-Reported Depression and Quality of Life in Mild-Moderate Alzheimer's Disease

OBJECTIVE

Prior studies have reported an association between depression and quality of life (QOL) in Alzheimer's disease (AD), but the effect of self- versus proxy rating of mood and QOL has not been described.

DESIGN

In this secondary analysis of data from a cohort study, the authors used a linear mixed-effects model to determine if the association between depression and QOL is affected by whether both measures are assessed by the same member of the patient-caregiver dyad.

SETTING

Participants and caregiver informants were recruited from 10 California Alzheimer Disease Centers.

PARTICIPANTS

A total of 137 participants with mild-to-moderate Alzheimer's disease and their caregivers.

MEASUREMENTS

Self- and proxy-rated scores on both the Geriatric Depression Scale (GDS) and the Quality of Life in Alzheimer's Disease scale (QoL-AD). Multivariable linear mixed-effects models were used to estimate the association between depression and QOL.

RESULTS

Results of the multivariable linear mixed-effects models showed a significant association between self-rated QoL-AD and self-rated (B = -0.49, p <0.0001) but not proxy-rated GDS (B = -0.07, p = 0.19) after adjusting for confounders. Likewise, there was a significant association between proxy-rated QoL-AD and proxy-rated GDS (B = -0.48, p <0.0001) but not self-rated GDS (B = 0.05, p = 0.36).

CONCLUSION

Depression was associated with QOL in AD over short-term longitudinal follow-up, but the association was not statistically significant if both instruments are not administered to the same member of the patient-caregiver dyad. The choice of self- versus proxy-reported QOL should be intentionally considered in future studies as it may influence reported outcomes.

Navigating the outcome maze: a scoping review of outcomes and instruments in clinical trials in genetic neurodevelopmental disorders and intellectual disability

Background

Individuals with genetic neurodevelopmental disorders (GNDs) or intellectual disability (ID) are often affected by complex neuropsychiatric comorbidities. Targeted treatments are increasingly available, but due to the heterogeneity of these patient populations, choosing a key outcome and corresponding outcome measurement instrument remains challenging.

Objectives

The aim of this scoping review was to describe the research on outcomes and instruments used in clinical trials in GNDs and ID.

Eligibility criteria

Clinical trials in individuals with GNDs and ID for any intervention over the past 10 years were included in the review.

Sources of evidence

MEDLINE, PsycINFO, and Cochrane CENTRAL were searched. Titles and abstracts were independently screened for eligibility with a subsample of 10% double-screening for interrater reliability. Data from full texts were independently reviewed. Discrepancies were discussed until consensus was reached.

Charting methods

Information was recorded on patient populations, interventions, designs, outcomes, measurement instruments, and type of reporter when applicable. Qualitative and descriptive analyses were performed.

Results

We included 312 studies reporting 91 different outcomes, with cognitive function most frequently measured (28%). Various outcome measurement instruments (n = 457) were used, with 288 in only a single clinical trial. There were 18 genetic condition-specific instruments and 16 measures were designed ad-hoc for one particular trial. Types of report included proxy-report (39%), self-report (22%), clinician-report (16%), observer-report (6%), self-assisted report (1%), or unknown (16%).

Conclusion

This scoping review of current practice reveals a myriad of outcomes and outcome measurement instruments for clinical trials in GNDs and ID. This complicates generalization, evidence synthesis, and evaluation. It underlines the need for consensus on suitability, validity, and relevancy of instruments, ultimately resulting in a core outcome set. A series of steps is proposed to move from the myriad of measures to a more unified approach.

Unravelling the Self-Report Versus Proxy-Report Conundrum for Older Aged Care Residents: Findings from a Mixed-Methods Study

OBJECTIVES

No guidance currently exists as to the cognition threshold beyond which self-reported quality of life for older people with cognitive impairment and dementia is unreliable.

METHODS

Older aged care residents (≥ 65 years) were randomly assigned to complete the EQ-5D-5L in computer-based (eye movements were tracked) or hard copy (participants were encouraged to 'think aloud') format. Cognition was assessed using the Mini-Mental State Examination (MMSE). Think aloud and eye tracking data were analysed by two raters, blinded to MMSE scores. At the participant level, predefined criteria were used to assign traffic light grades (green, amber, red). These grades indicate the extent to which extracted data elements provided evidence of self-report reliability. The MMSE-defined cognition threshold was determined following review of the distributions of assigned traffic light grades.

RESULTS

Eighty-one residents participated and provided complete data (38 eye tracking, 43 think aloud). In the think aloud cohort, all participants with an MMSE score ≤ 23 (n = 10) received an amber or red grade, while 64% of participants with an MMSE score ≥ 24 (21 of 33) received green grades. In the eye tracking cohort, 68% of participants with an MMSE score ≥ 24 (15 of 22) received green grades. Of the 16 eye tracking participants with an MMSE score ≤ 23, 14 (88%) received an amber or red grade.

CONCLUSIONS

Most older residents with an MMSE score ≥ 24 have sufficient cognitive capacity to self-complete the EQ-5D-5L. More research is needed to better understand self-completion reliability for other quality-of-life instruments in cognitively impaired populations.

Effectiveness, acceptability, and completeness and quality of intervention reporting of psychological interventions for people with dementia or mild cognitive impairment: protocol for a mixed-methods systematic review

INTRODUCTION

Mental health difficulties such as anxiety and depression have negative impacts on psychological well-being and are common in people with dementia and mild cognitive impairment. However, access to psychological treatments is limited. This mixed-method systematic review will: (1) examine the effectiveness of psychological interventions to improve mental health and psychological well-being in people with dementia or mild cognitive impairment; (2) examine the effectiveness of these psychological interventions to improve mental health and psychological well-being in informal caregivers; (3) examine potential clinical and methodological moderators associated with effectiveness; (4) explore factors associated with the acceptability of psychological interventions from the perspective of key stakeholders; and (5) examine the completeness and quality of intervention reporting.

METHODS AND ANALYSIS

Electronic databases (ASSIA, CENTRAL, CINAHL, EMBASE, PsycINFO and MEDLINE) will be systematically searched and supplemented with expert contact, reference and citation checking, and grey literature searches. If possible, we will conduct a meta-analysis to examine the overall effectiveness of psychological interventions to improve mental health and psychological well-being in people with dementia or mild cognitive impairment and their informal caregivers; and examine potential clinical and methodological moderators associated with effectiveness. We will conduct a deductive framework synthesis, informed by the theoretical framework of acceptability, to explore factors associated with the acceptability of psychological interventions from the perspective of key stakeholders. In accordance with Joanna Briggs Institute guidance, we will adopt a convergent segregated approach to data synthesis and integration of quantitative and qualitative findings. We will examine the completeness and quality of intervention reporting according to the Template for Intervention Description and Replication checklist and guide.

ETHICS AND DISSEMINATION

No primary data will be collected, and therefore, ethical approval is not required. Results will be disseminated through a peer-reviewed publication, academic conferences, and plain language summaries.

Delivery of Neuropsychological Interventions for Adult and Older Adult Clinical Populations: An Australian Expert Working Group Clinical Guidance Paper

Delivery of neuropsychological interventions addressing the cognitive, psychological, and behavioural consequences of brain conditions is increasingly recognised as an important, if not essential, skill set for clinical neuropsychologists. It has the potential to add substantial value and impact to our role across clinical settings. However, there are numerous approaches to neuropsychological intervention, requiring different sets of skills, and with varying levels of supporting evidence across different diagnostic groups. This clinical guidance paper provides an overview of considerations and recommendations to help guide selection, delivery, and implementation of neuropsychological interventions for adults and older adults. We aimed to provide a useful source of information and guidance for clinicians, health service managers, policy-makers, educators, and researchers regarding the value and impact of such interventions. Considerations and recommendations were developed by an expert working group of neuropsychologists in Australia, based on relevant evidence and consensus opinion in consultation with members of a national clinical neuropsychology body. While the considerations and recommendations sit within the Australian context, many have international relevance. We include (i) principles important for neuropsychological intervention delivery (e.g. being based on biopsychosocial case formulation and person-centred goals); (ii) a description of clinical competencies important for effective intervention delivery; (iii) a summary of relevant evidence in three key cohorts: acquired brain injury, psychiatric disorders, and older adults, focusing on interventions with sound evidence for improving activity and participation outcomes; (iv) an overview of considerations for sustainable implementation of neuropsychological interventions as 'core business'; and finally, (v) a call to action.

Effects of music therapy on cognition, quality of life, and neuropsychiatric symptoms of patients with dementia: A systematic review and meta-analysis of randomized controlled trials

Dementia is a major cause of disability and dependency. Pharmacological interventions are commonly provided to patients with dementia to delay the deterioration of cognitive functions but cannot alter the course of disease. Nonpharmacological interventions are now attracting increasing scholarly interest. In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement, we aim to assess the effectiveness of music-based therapies on the cognition, quality of life (QoL), and neuropsychiatric symptoms of patients with dementia through a systematic review and meta-analysis of randomized controlled trials (RCTs). The PubMed, Embase, and Cochrane databases were searched for reports of RCTs examining the effectiveness of music-based therapies for dementia published as of April 2023. A total of 674 articles were screened, and 22 trials from 21 studies (1780 patients) met the eligibility criteria. In 15 trials, music-based therapies significantly improved the cognition of patients with dementia compared with non-music therapies. In 11 trials, music-based therapies also significantly improved the QoL of patients with dementia compared with non-music therapies. In six trials, music-based therapies significantly improved patients' neuropsychiatric symptoms compared with non-music therapies. In conclusion, music-based therapy is recognized as a safe and effective alternative approach for patients with dementia.

Novel small molecules inhibit proteotoxicity and inflammation: Mechanistic and therapeutic implications for Alzheimer's Disease, healthspan and lifespan- Aging as a consequence of glycolysis

Inflammation drives many age-related, especially neurological, diseases, and likely mediates age-related proteotoxicity. For example, dementia due to Alzheimer's Disease (AD), cerebral vascular disease, many other neurodegenerative conditions is increasingly among the most devastating burdens on the American (and world) health system and threatens to bankrupt the American health system as the population ages unless effective treatments are developed. Dementia due to either AD or cerebral vascular disease, and plausibly many other neurodegenerative and even psychiatric conditions, is driven by increased age-related inflammation, which in turn appears to mediate Abeta and related proteotoxic processes. The functional significance of inflammation during aging is also supported by the fact that Humira, which is simply an antibody to the pro-inflammatory cytokine TNF-a, is the best-selling drug in the world by revenue. These observations led us to develop parallel high-throughput screens to discover small molecules which inhibit age-related Abeta proteotoxicity in a C. elegans model of AD AND LPS-induced microglial TNF-a. In the initial screen of 2560 compounds (Microsource Spectrum library) to delay Abeta proteotoxicity, the most protective compounds were, in order, phenylbutyrate, methicillin, and quetiapine, which belong to drug classes (HDAC inhibitors, beta lactam antibiotics, and tricyclic antipsychotics, respectably) already robustly implicated as promising to protect in neurodegenerative diseases, especially AD. RNAi and chemical screens indicated that the protective effects of HDAC inhibitors to reduce Abeta proteotoxicity are mediated by inhibition of HDAC2, also implicated in human AD, dependent on the HAT Creb binding protein (Cbp), which is also required for the protective effects of both dietary restriction and the daf-2 mutation (inactivation of IGF-1 signaling) during aging. In addition to methicillin, several other beta lactam antibiotics also delayed Abeta proteotoxicity and reduced microglial TNF-a. In addition to quetiapine, several other tricyclic antipsychotic drugs also delayed age-related Abeta proteotoxicity and increased microglial TNF-a, leading to the synthesis of a novel congener, GM310, which delays Abeta as well as Huntingtin proteotoxicity, inhibits LPS-induced mouse and human microglial and monocyte TNF-a, is highly concentrated in brain after oral delivery with no apparent toxicity, increases lifespan, and produces molecular responses highly similar to those produced by dietary restriction, including induction of Cbp inhibition of inhibitors of Cbp, and genes promoting a shift away from glycolysis and toward metabolism of alternate (e.g., lipid) substrates. GM310, as well as FDA-approved tricyclic congeners, prevented functional impairments and associated increase in TNF-a in a mouse model of stroke. Robust reduction of glycolysis by GM310 was functionally corroborated by flux analysis, and the glycolytic inhibitor 2-DG inhibited microglial TNF-a and other markers of inflammation, delayed Abeta proteotoxicity, and increased lifespan. These results support the value of phenotypic screens to discover drugs to treat age-related, especially neurological and even psychiatric diseases, including AD and stroke, and to clarify novel mechanisms driving neurodegeneration (e.g., increased microglial glycolysis drives neuroinflammation and subsequent neurotoxicity) suggesting novel treatments (selective inhibitors of microglial glycolysis).

Understanding the impact of tuberous sclerosis complex: development and validation of the TSC-PROM

BACKGROUND

Tuberous sclerosis complex (TSC) is a rare and complex genetic disorder, associated with tumor growth in various organ systems, epilepsy, and a range of neuropsychiatric manifestations including intellectual disability. With improving patient-centered care and targeted therapies, patient-reported outcome measures (PROMs) are needed to measure the impact of TSC manifestations on daily functioning. The aim of this study was to develop a TSC-specific PROM for adults that captures the impact of TSC on physical functions, mental functions, activity and participation, and the social support individuals with TSC receive, called the TSC-PROM.

METHODS

COSMIN methodology was used to develop a self-reported and proxy-reported version. Development and validation consisted of the following studies: PROM development, content validity, structural validity, internal consistency, and construct validity. The International Classification of Functioning and Disability was used as a framework. Content validity was examined by a multidisciplinary expert group and cognitive interview study. Structural and construct validity, and internal consistency were examined in a large cohort, using confirmatory factor analysis, hypotheses testing, and Cronbach's alpha.

RESULTS

The study resulted in an 82-item self version and 75-item proxy version of the TSC-PROM with four subscales (physical functions 18 and 19 items, mental functions 37 and 28 items, activities and participation 13 and 14 items, social support 13 items, for self version and proxy version respectively). Sufficient results were found for structural validity with sufficient unidimensionality for each subscale. With regard to construct validity, 82% of the hypotheses were met for the self version and 59% for the proxy version. The PROM showed good internal consistency (Cronbach's alpha 0.78-0.97).

CONCLUSIONS

We developed a PROM for adults with TSC, named TSC-PROM, showing sufficient evidence for reliability and validity that can be used in clinical and research settings to systematically gain insight into their experiences. It is the first PROM in TSC that addresses the impact of specific TSC manifestations on functioning, providing a valuable, patient-centered addition to the current clinical outcomes.

Outpatient opioid prescribing by Alzheimer's diagnosis among older adults with pain in United States

OBJECTIVE

To examine opioid prescribing practices for pain in older adults with and without Alzheimer's Disease and Related Dementias (ADRD).

METHODS

This cross-sectional study used National Ambulatory Medical Care Survey data (2014-2016, and 2018). Adults aged ≥ 50 years with pain were analyzed. Prescribing of opioid and concomitant sedative prescriptions (including benzodiazepines, Z-drugs, and barbiturates) were identified by the Multum lexicon code. Multivariable logistic regression evaluated the risk of opioid prescribing or co-prescribing of opioid and sedative associated with ADRD in older adults with pain.

RESULTS

There were 13,299 office visits in older adults with pain, representing 451.75 million visits. Opioid prescribing occurred in 27.19%; 30% involved co-prescribing of opioids and sedatives. ADRD was not associated with opioid prescribing or co-prescribing of opioid and sedative therapy.

CONCLUSIONS

Opioid and sedatives are commonly prescribed in older adults with pain. Longitudinal studies need to understand the etiology and chronicity of opioid use in older patients, specifically with ADRD.

Perspectives on Aging and Quality of Life

The aging of the world's population and the health problems accompanying it are becoming increasingly severe. Healthcare policies in developed countries focus on how to prevent and treat diseases associated with aging and how to maintain quality of life. Typical age-related diseases include deafness, cataracts, osteoarthritis, chronic obstructive pulmonary disease, diabetes mellitus, and dementia. Although the mechanisms by which these diseases develop differ, they are all caused by the accumulation of molecular and cellular damage over time. In addition, age-related diseases can cause a decline in physical and mental functions and the ability to perform activities of daily living, as well as the loss of roles in society and a sense of fulfillment in life. Therefore, there is a need for treatment and measures to accurately grasp and maintain quality of life. This review aims to introduce areas and representative papers expected to be contributed to the special issue of "Aging and Quality of Life".

Lawton's Instrumental Activities of Daily Living for Greek-Speaking Adults with Cognitive Impairment: A Psychometric Evaluation Study with Additional Receiver Operating Characteristic Curve Analysis

One of the components of a dementia diagnosis is the assessment of functional abilities. These abilities are measured via screeners, such as the Instrumental Activities of Daily Living (IADL) scale. The IADL scale is a valid tool that has been adapted in many languages. This study aimed to provide a cut-off point and validate the Greek version of the IADL scale in populations with cognitive impairment. IADL data were collected from 132 individuals: 24 PD patients, 24 Parkinson's disease dementia (PDD) patients, and 24 AD patients. The remaining 60 participants were cognitive healthy adults (CHAs). The CHA group and the PD group served as the cognitively unimpaired group (CUG), while the PDD and AD groups served as the cognitively impaired group (CIG). Additionally, the MMSE, the AMTS, the Clock Drawing Test CDT, the Arizona Battery for Communication Disorders of Dementia (ABCD), the NPI, and the GDS-15 were administered to the participants. Statistically significant differences in the IADL scores were exhibited between all subgroups. The IADL scale showed high internal consistency (Cronbach's alpha = 0.890). A threshold equal to 6.00 (AUC = 0.888, p < 0.001) was estimated between the CUG and the CIG. Significant positive correlations were observed between IADL and MMSE (r = 0.764, p < 0.001), IADL and AMTS (r = 0.724, p < 0.001), IADL and ABCD (r = 0.702, p < 0.001), and IADL and CDT (r = 0.627, p < 0.001) results. Given the obtained results, the IADL scale is a valid tool for clinical use with high reliability and sensitivity. Also, the IADL scale is a valuable instrument for screening functional abilities associated with cognitive impairment.

Establishing the Feasibility and Acceptability of a Caregiver Targeted Intervention to Improve Pain Assessment Among Persons With Dementia

Background and Objectives

Despite its prevalence and impact, pain is underdetected and undermanaged in persons with dementia. Family caregivers are well positioned to detect pain and facilitate its management in their care recipients, but they lack training in symptom recognition and communication. This study reports findings from a pilot trial evaluating the Pain Identification and Communication Toolkit (PICT), a multicomponent intervention that provides training in observational pain assessment and coaching in pain communication techniques.

Research Design and Methods

Family caregivers of persons with comorbid pain and moderate-to-advanced dementia were randomly assigned to PICT (n = 19) or a control condition (n = 15). Caregivers in the PICT group participated in four weekly sessions delivered by telephone with a trained interventionist; caregivers in the control group received an information pamphlet about pain and dementia. All participants completed surveys at baseline and 12 weeks. Caregivers in the intervention group also completed semistructured interviews at 12 weeks. Quantitative data were analyzed using descriptive statistics and t tests; qualitative data were analyzed using content analysis.

Results

All participants (100%) in the PICT group completed the intervention and most completed the 12-week assessment (94%). PICT randomized caregivers reported that the intervention helped them to feel more confident in their ability to recognize (67%) and communicate about pain symptoms (83%). At 12 weeks, caregivers in the PICT group showed a statistically significant improvement in self-efficacy in pain-related communication. In qualitative interviews, caregivers emphasized the utility of PICT's components, including pain assessment tools, and offered considerations for future enhancements, such as technology-based adaptations and integration within care delivery systems.

Discussion and Implications

This pilot trial demonstrates that PICT is feasible to implement, acceptable to caregivers, and has the potential to improve confidence in recognizing and communicating about pain. Results support conducting a fully powered efficacy trial, an important step toward future integration into real-world care delivery.

Can Nutrition Contribute to a Reduction in Sarcopenia, Frailty, and Comorbidities in a Super-Aged Society?

Many countries are facing the advent of super-aging societies, where sarcopenia and frailty will become pertinent problems. The prevalence of comorbidities is a major problem in countries with aged populations as elderly people suffer from various diseases, such as diabetes, heart failure, chronic kidney disease and dementia. All of these diseases are associated with sarcopenia and frailty, and they frequently cause falls, fractures, and a decline in activities of daily living. Fractures in the elderly people are associated with bone fragility, which is influenced by diabetes and chronic kidney disease. Nutritional support for chronic disease patients and sarcopenic individuals with adequate energy and protein intake, vitamin D supplementation, blood glucose level management for individuals with diabetes, obesity prevention, nutritional education for healthy individuals, and the enlightenment of society could be crucial to solve the health-related problems in super-aging societies.

Psychometrics of the Physical Resilience Scale in Older Adults Living with Dementia: Proxy Responses

Objectives: The purpose of this study was to determine if proxies can complete the Physical Resilience Scale for older adults living with dementia. Methods: This was a descriptive study using Rasch analysis and baseline data from the Function Focused Care for Acute Care Using the Evidence Integration Triangle trial. The first 240 patients living with dementia were included in this analysis. Results: There was evidence of reliability based on person and item separation index. There was no evidence of Differential Item Functioning (DIF) between genders and a DIF by race on Item 7. Validity was supported based on items fitting the model with the exception of one item, and a significant relationship between physical resilience and pain and function. Discussion: There is some evidence that the Physical Resilience Scale is reliable and valid when completed by proxy reports. Future use should remove one of the items due to redundancy.

Effects of cognitive stimulation therapy on patients with dementia: An umbrella review of systematic reviews and meta-analyses

BACKGROUND

Dementia is characterized by significant cognitive decline that results in disturbance of daily activities. Increasing number of meta-analyses has examined the efficacy of cognitive stimulation therapy (CST) for dementia. However, there is a lack of comprehensive reports that specifically discuss the strength of evidence to support CST for dementia.

PURPOSE

This study aimed to summarize evidence regarding the efficacy of CST on people with dementia.

DESIGN

Umbrella review of systematic reviews and meta-analyses.

METHODS

We searched Cochrane Library, PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data, China Biology Medicine disc (CBMdisc), and VIP databases from inception to December 31, 2022. The methodological quality of the identified studies was assessed using A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR 2). Studies scoring 9-12 (moderate quality) points or higher were further analyzed using Grades of Recommendations Assessment, Development and Evaluation (GRADE) principles.

RESULTS

A total of 14 systematic reviews and meta-analyses were included in the umbrella review. The methodological quality of most included reviews was rated as moderate according to AMSTAR 2 rating system. In these studies, we summarized the characteristics of the content, providers, frequency, period and setting of CST, and examined eight health outcomes related to CST, including cognition, depression, behavioral symptoms, quality of life (QoL), activities of daily living (ADL), language and communication, anxiety, and memory. Eleven studies with low to high rating of overall confidence (OC) consistently reported that CST could significantly improve cognition of people with dementia, including high-quality supporting evidence. However, the effect of CST on other health outcomes for people with dementia (e.g., depression, behavioral symptoms, QoL, ADL) is inconsistent, with low- to moderate-quality evidence ratings. Compared with the above results, few studies have reported the effects of CST on communication, anxiety, and memory for people with dementia.

CONCLUSIONS

In the future, the design and reporting of systematic reviews and meta-analyses should incorporate high-quality research metrics in accordance with AMSTAR 2 criteria. The current review supports CST as an effective treatment for improving cognitive function in patients with dementia. Multi-component interventions are more effective than single-component interventions and need to be delivered regularly.

REGISTRATION

The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42022364259).

Life satisfaction among persons living with dementia and those without dementia

BACKGROUND

Despite possible major adverse cognitive, physical, social, and behavioral consequences, little is known about how persons living with dementia perceive satisfaction with life, a key component of well-being. We sought to examine (i) whether persons living with dementia perceive a lower level of satisfaction compared to their peers without dementia and (ii) whether the associations between individual characteristics and life satisfaction are different between persons living with and without dementia.

METHODS

Using a nationally representative sample of community-dwelling older adults aged ≥70 years in the U.S. from the Health and Retirement Study, we compared scores on the Satisfaction with Life Scale (SWLS), a self-reported 5-item scale ranging from 1 to 7 (more satisfaction), between persons with probable dementia (n = 341) and those without (n = 5530), adjusting for individual characteristics. We also tested whether the associations between the individual characteristics and SWLS differ by dementia status.

RESULTS

Scores on SWLS did not differ between persons with probable dementia and those without when adjusting for individual characteristics including limitations in activities of daily living (ADL) (adjusted difference, -0.09; 95% CI, -0.33 to +0.15; p-value, 0.45). However, dementia status was associated with lower life satisfaction through the mediation of limitations in ADL (total effect, -0.29; bootstrapped 95% CI, -0.47 to -0.12). Most individual characteristics associated with lower life satisfaction were similar in the two groups, including younger age, more limitations in ADL, and depression. Less wealth was associated with lower satisfaction among persons without dementia but not among those with probable dementia.

CONCLUSIONS

Dementia status was only modestly associated with lower life satisfaction through the mediation of limitations in ADL among participants who were able to provide response. Future research is warranted to determine whether life satisfaction can be used as a meaningful outcome when evaluating well-being among persons living with dementia.

Personally tailored activities for improving psychosocial outcomes for people with dementia in long-term care

BACKGROUND

People with dementia who are being cared for in long-term care settings are often not engaged in meaningful activities. We wanted to know whether offering them activities which are tailored to their individual interests and preferences could improve their quality of life and reduce agitation. This review updates our earlier review published in 2018.

OBJECTIVES

∙ To assess the effects of personally tailored activities on psychosocial outcomes for people with dementia living in long-term care facilities. ∙ To describe the components of the interventions. ∙ To describe conditions which enhance the effectiveness of personally tailored activities in this setting.

SEARCH METHODS

We searched the Cochrane Dementia and Cognitive Improvement Group's Specialized Register, on 15 June 2022. We also performed additional searches in MEDLINE, Embase, PsycINFO, CINAHL, Web of Science, ClinicalTrials.gov, and the World Health Organization (WHO) ICTRP, to ensure that the search for the review was as up-to-date and as comprehensive as possible.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and controlled clinical trials offering personally tailored activities. All interventions included an assessment of the participants' present or past preferences for, or interest in, particular activities as a basis for an individual activity plan. Control groups received either usual care or an active control intervention.

DATA COLLECTION AND ANALYSIS

Two authors independently selected studies for inclusion, extracted data and assessed the risk of bias of included studies. Our primary efficacy outcomes were agitation and participant quality of life. Where possible, we pooled data across studies using a random effects model.

MAIN RESULTS

We identified three new studies, and therefore included 11 studies with 1071 participants in this review update. The mean age of participants was 78 to 88 years and most had moderate or severe dementia. Ten studies were RCTs (three studies randomised clusters to the study groups, six studies randomised individual participants, and one study randomised matched pairs of participants) and one study was a non-randomised clinical trial. Five studies included a control group receiving usual care, five studies an active control group (activities which were not personally tailored) and one study included both types of control group. The duration of follow-up ranged from 10 days to nine months. In nine studies personally tailored activities were delivered directly to the participants. In one study nursing staff, and in another study family members, were trained to deliver the activities. The selection of activities was based on different theoretical models, but the activities delivered did not vary substantially. We judged the risk of selection bias to be high in five studies, the risk of performance bias to be high in five studies and the risk of detection bias to be high in four studies. We found low-certainty evidence that personally tailored activities may slightly reduce agitation (standardised mean difference -0.26, 95% CI -0.53 to 0.01; I² = 50%; 7 studies, 485 participants). We also found low-certainty evidence from one study that was not included in the meta-analysis, indicating that personally tailored activities may make little or no difference to general restlessness, aggression, uncooperative behaviour, very negative and negative verbal behaviour (180 participants). Two studies investigated quality of life by proxy-rating. We found low-certainty evidence that personally tailored activities may result in little to no difference in quality of life in comparison with usual care or an active control group (MD -0.83, 95% CI -3.97 to 2.30; I² = 51%; 2 studies, 177 participants). Self-rated quality of life was only available for a small number of participants from one study, and there was little or no difference between personally tailored activities and usual care on this outcome (MD 0.26, 95% CI -3.04 to 3.56; 42 participants; low-certainty evidence). Two studies assessed adverse effects, but no adverse effects were observed. We are very uncertain about the effects of personally tailored activities on mood and positive affect. For negative affect we found moderate-certainty evidence that there is probably little to no effect of personally tailored activities compared to usual care or activities which are not personalised (standardised mean difference -0.02, 95% CI -0.19 to 0.14; 6 studies, 632 participants). We were not able to undertake meta-analyses for engagement and sleep-related outcomes, and we are very uncertain whether personally tailored activities have any effect on these outcomes. Two studies that investigated the duration of the effects of personally tailored activities indicated that the intervention effects they found persisted only during the period of delivery of the activities.

AUTHORS' CONCLUSIONS

Offering personally tailored activities to people with dementia in long-term care may slightly reduce agitation. Personally tailored activities may result in little to no difference in quality of life rated by proxies, but we acknowledge concerns about the validity of proxy ratings of quality of life in severe dementia. Personally tailored activities probably have little or no effect on negative affect, and we are uncertain whether they have any effect on positive affect or mood. There was no evidence that interventions were more likely to be effective if based on one theoretical model rather than another. We included three new studies in this updated review, but two studies were pilot trials and included only a small number of participants. Certainty of evidence was predominately very low or low due to several methodological limitations of and inconsistencies between the included studies. Evidence is still limited, and we remain unable to describe optimal activity programmes. Further research should focus on methods for selecting appropriate and meaningful activities for people in different stages of dementia.

Association of nonpharmacological interventions for cognitive function in older adults with mild cognitive impairment: a systematic review and network meta-analysis

BACKGROUND

Understanding the effectiveness of nonpharmacological interventions to improve cognitive function in older adults with MCI and identifying the best intervention may help inform ideas for future RCT studies and clinical decision-making.

AIM

The main focus of this study was to assess the comparative effectiveness of nonpharmacological interventions on cognitive function in older adults with MCI and to rank the interventions.

METHODS

RCT studies until September 2022 were searched from six databases, including PubMed, the Cochrane Library, Embase, Web of Science, PsycINFO and CINAHL. The risk of bias in eligible trials was evaluated using the Cochrane Risk of Bias tool. Both pairwise and network meta-analyses were used, and pooled effect sizes were reported using SMD and the corresponding 95% confidence intervals.

RESULTS

A total of 28 RCT studies were included in this study, pooling 18 categories of nonpharmacological interventions. MBE (mind-body exercise) (SMD (standard mean difference): 0.24, 95% CI: 0.08-0.41, P = 0.004), DTE (dual-task exercise) (SMD: 0.61, 95% CI: 0.09-1.13, P = 0.02), PE (physical exercise) (SMD: 0.58, 95% CI: 0.04-1.12, P = 0.03) may be effective in improving cognitive function in older adults with MCI. Acupressure + CT (cognitive training) was the top-ranked intervention among all interventions. No greater benefits of MA (mindful awareness) on cognitive function were found.

CONCLUSIONS

Overall, nonpharmacological interventions significantly improved cognitive function in older adults with MCI. Acupressure + CT(cognitive training) was the most effective intervention for managing cognitive impairment. Future studies with high quality and large sample size RCT studies are needed to confirm our results.

Physical and cognitive function to explain the quality of life among older adults with cognitive impairment: exploring cognitive function as a mediator

BACKGROUND

Physical and cognitive function are both indicators of aging, characterized by a loss of adaptive response to life challenges and functional limitations, subsequently affecting their quality of life. This study aimed to identify the direct effect of physical function and the indirect effect of cognitive function on the quality of life in older adults with mild cognitive impairment.

METHODS

The study participants were 79 older adults recruited from community centers in four urban districts of Korea. All participants completed a self-reported questionnaire for demographic characteristics and outcome variables. Outcome measures included physical function (grip strength, balance, and mobility), cognitive function, and mental and physical components of quality of life (QOL). Statistical analyses were conducted using hierarchical multiple linear regression and the PROCESS macro for mediation analysis.

RESULTS

The mean age of participants was 77.46 years old with an elementary or lower education level (53.2%). The mean score of cognitive function was 16.39 (SD = 6.5). Physical function (grip strength, balance, mobility) and cognitive function explained 25% of the variance in physical (p = 0.004) and 29% in mental (p < 0.001) components of QOL after controlling for age, sex, and education level. Mobility was associated with both physical (β=-0.27, p = 0.024) and mental (β=-0.36, p = 0.002) components of QOL. The cognitive function partially mediated the relationship between balance and the physical component of QOL; the proportion of mediation was 55%.

CONCLUSION

In conclusion, physical and cognitive function were significant predictors of QOL in older adults with cognitive impairment. Specifically, balance has significant indirect effects on the physical component of QOL through cognitive function as a mediator. Health-promoting strategies could be more effective when focusing on the direct effect of physical function as well as the mediating effect of cognitive function to promote the quality of life in this population.

The impact of active community-based survey on dementia detection ratio in Taiwan: A cohort study with historical control

Background

Although early dementia detection is crucial to optimize the treatment outcomes and the management of associated symptoms, the published literature is scarce regarding the effectiveness of active screening protocols in enhancing dementia awareness and increasing the rate of early detection. The present study compared the detection ratio of an active community-based survey for dementia detection with the detection ratio of passive screening during routine clinical practice. Data for passive screening were obtained from the National Health Insurance (NHI) system, which was prospectively collected during the period from 2000 to 2003.

Design

A population-based cohort study with historical control.

Setting

Taiwan.

Participants

A total of 183 participants aged 65 years or older were involved in a community-based survey. Data from 1,921,308 subjects aged 65 years or older were retrieved from the NHI system.

Measurements

An adjusted detection ratio, defined as a ratio of dementia prevalence to incidence was used.

Results

The results showed that the dementia prevalence during the 2000-2003 period was 2.91% in the elderly population, compared with a prevalence of 6.59% when the active survey was conducted. The incidence of dementia in the active survey cohort was 1.83%. Overall, the dementia detection ratio was higher using active surveys [4.23, 95% confidence interval (CI): 2.68-6.69] than using passive detection (1.45, 95% CI: 1.43-1.47) for those aged 65-79 years. Similar findings were observed for those aged 80 years and older.

Conclusion

The implementation of an active community-based survey led to a 3-fold increase in the detection rate of early dementia detection compared to passive screening during routine practice.

Effect of Nordic Sensi® Chair on Behavioral and Psychological Symptoms of Dementia in Nursing Homes Residents: A Randomized Controlled Trial

BACKGROUND

Behavioral and psychological symptoms of dementia (BPSD) are present in most people with dementia (PwD), including Alzheimer's disease. There is consensus that non-pharmacological therapies represent the first line of treatment to address BPSD.

OBJECTIVE

We explore the efficacy of the use of a rocking chair (Nordic Sensi® Chair, NSC) in the treatment of BPSD in nursing home residents with moderate and severe dementia.

METHODS

We carried out a 16-week randomized, single-blind, controlled, clinical trial with PwD admitted to nursing homes. Participants were assigned to a treatment group (n = 40) that received three times a week one session per day of 20 minutes in the NSC and a control group (n = 37). The Neuropsychiatric Inventory-Nursing Home (NPI-NH) was used as primary efficacy outcome. Occupational distress for the staff was evaluated using the NPI-NH Occupational Disruptiveness subscale (NPI-NH-OD). Statistical analyses were conducted by means of a Mixed Effects Model Analysis.

RESULTS

Treatment with the NSC was associated with a beneficial effect in most of BPSD, as reflected by differences between the treatment and control group on the NPI-NH total score (mean change score -18.87±5.56 versus -1.74±0.67, p = 0.004), agitation (mean change score -2.32±2.02 versus -0.78±1.44, p = 0.003) and irritability (mean change score -3.35±2.93 versus -1.42±1.31, p = 0.004). The NPI-NH-OD total score also improved the most in the treatment group (mean change score -9.67±7.67 versus -7.66±6.08, p = 0.003).

CONCLUSIONS

The reduction in overall BPSD along with decreased caregiver occupational disruptiveness represent encouraging findings, adding to the potential of nonpharmacological interventions for nursing home residents living with dementia.

Quality of life among community-dwelling older adults: evidence from a large population-based study in rural Sri Lanka

PURPOSE

Against the backdrop of the ever-increasing aging population in Sri Lanka and the scarcity of local evidence on quality of life (QoL) among rural elderly, this study was conducted to assess the QoL of the community-dwelling older adults in rural Sri Lanka.

METHODS

This cross-sectional study was conducted among community-dwelling older adults (60-74 years) in a selected rural setting in Sri Lanka. K-means cluster analysis was used to stratify participants into 'low' and 'high' levels of QoL and then significant associations between these clusters and underlying socio-demographic and self-reported health related factors were estimated using bivariate and subsequent multivariable binary logistic regression models.

RESULTS

The final sample consisted of 3573 community-dwelling older adults (response rate 97.8%). The mean (SD) age of the sample was 66.7 (4.3) years and the majority were females (n = 2130, 59.6%). Amongst the six QoL domains assessed (physical, psychological, social, functional, environmental and spiritual domains), the highest and the lowest mean (SD) scores were reported for the functional [63.4 (16.9)] and the physical [52.9 (15.0)] domains, respectively. Aged 70 years or more, either unmarried/widowed/divorced, lower educational levels and having chronic illnesses were statistically significant associations of QoL (p < 0.05).

CONCLUSION

The QoL among community-dwelling older adults in rural Sri Lanka is moderate. As having social support, absence of chronic diseases and good education level were found to be associated with better QoL, strengthening community-based interventions to improve these aspects by incorporating the evidence generated by other longitudinal studies is recommended.

Key Stakeholders' Experiences and Perceptions of Virtual Reality for Older Adults Living With Dementia: Systematic Review and Thematic Synthesis

BACKGROUND

Technology is increasingly being used and evolving in the dementia care landscape. One such technology that has gained traction over the last decade is virtual reality (VR). VR is being applied in many areas of dementia care, including cognitive assessment and training, reminiscence therapy, music therapy, and other recreational VR applications. Despite the plethora of applications, they are often not shaped by the experiences and perceptions of older adults living with dementia. Currently, there is no qualitative evidence synthesis (QES) to explore this area. This review aimed to provide qualitative evidence supporting existing systematic reviews in this area.

OBJECTIVE

The aim of this QES was to explore key stakeholders' experiences and perceptions of VR for older adults living with dementia. It aimed to explore the barriers and facilitators to VR use and provide recommendations for future design and implementation.

METHODS

QES was used, which involved a systematic search of 6 databases to identify studies that qualitatively explored key stakeholders' experiences and perceptions of VR for older adults living with dementia. Thematic synthesis was used to integrate the findings of 14 studies (from 15 reports). The Critical Appraisal Skills Programme tool was used to assess the methodological quality of the included studies. The confidence placed in the review findings was assessed using the GRADE-CERQUAL (Confidence in the Evidence from Reviews of Qualitative research).

RESULTS

A total of 15 reports from 14 studies were included in the review, consisting of a range of levels of VR immersion, stages of dementia, and care contexts. Three analytical themes were generated: stepping into virtuality, a virtual world, and returning to reality. The results indicate the importance of sensitively designing and introducing VR to this population, as older adults living with dementia often have no prior experience of using this technology. VR can be a positive experience for older adults living with dementia and can provide meaningful interactions, positive expressions, and long-term impacts on everyday functioning. However, it should be acknowledged that some negative associations must be accounted for before, during, and after use.

CONCLUSIONS

This review highlights the positive implications as well as negative associations of VR use. It emphasizes the need for VR design and implementation driven by the needs and views of older adults living with dementia as well as with other key stakeholders. Future research needs to explore the vital role that older adults living with dementia can play in the design process and how they can be empowered to meaningfully design and use this technology.

Cardiovascular Comorbidities in Relation to the Functional Status and Vitamin D Levels in Elderly Patients with Dementia

(1) Background: As dementia is an incurable, multifactorial neurodegenerative disease, we gathered and analyzed a number of patient characteristics, assessing possible correlations that may support early diagnosis and a more accurate prognosis for cognitively impaired patients. (2) Methods: We used standard clinical parameters (cognitive and functional status, comorbidities, and plasma vitamin D levels) in a study group of 162 patients aged above 55 years old. (3) Results: We reported a higher incidence of cardiovascular and metabolic comorbidities in patients with severe or moderate cognitive impairment; a validated correlation between functional status, cognitive status, and serum vitamin D levels; and a more frequently associated profile of neurologic comorbidities in patients with a more significant cognitive deficiency. (4) Conclusions: The present research adds data on the significant correlations of cognitive deficits with cardiovascular, metabolic, and neurologic diseases (and the lack of correlation with osteoarticular illness). Clinicians should make the best use of the current screening and assessment tools (such as the functional scoring of daily activities, cognitive evaluation, and the screening of risk factors). Our data may offer starting points for future in-depth analysis of dementia-modifiable risk factors.

Definition and Contextual Factors of Nursing Home Residents' Mobility in a Holistic View: A Delphi Study

Background and Objectives

Current definitions of older adults' mobility do not cover the full range of influencing factors and do not consider nursing home residents. The present study reports expert ratings from a Delphi study regarding factors influencing the mobility of long-term nursing home residents.

Research Design and Methods

We invited 129 professionals with expertise in a field relevant to research on mobility in older adults such as health care, medicine, or human movement science to participate in a Delphi study comprising 3 rounds of online questionnaires. Up to 40 experts participated in each round. In the first round, we used open-ended questions to solicit possible definitions, contextual factors, and assessment tools. In the second round, the participants used Likert scales (1-10) to rate their suitability. In the final round, we presented a definition based on consensus as well as the top-rated contextual factors and assessment tools from the first 2 rounds for a final rating of agreement.

Results

The experts showed broad agreement on the final version of the mobility definition, with 8.9 ± 1.4 (mean ± standard deviation) out of 10 points. The experts also showed broad consensus on the selected contextual factors, with 8.4 ± 1.8 points to 8.9 ± 1.2 points (out of 10 points). This was also the case for the top 3 assessment tools selected from results of previous rounds, which showed an agreement of 7 or more points (out of 10 points) by 81.6% to 100% of all experts in the different categories.

Discussion and Implications

Given that an interdisciplinary group of experts considered various hitherto neglected contextual factors as relevant, the Delphi survey and its results imply the need for an updated interdisciplinary and holistic understanding of mobility in nursing home residents and can provide a basis for putting it into practice.

A Critical Study on the Impact of Dementia on Older People Undergoing Treatment in Care Homes

Maximum healthcare needs for older people are complex due to diseases, comorbidities, or disabilities, including long-term or mental and physical health issues. Various residential and nursing care homes help care for older people, especially those with special medical needs. Among these special medical needs, dementia is one medical condition requiring exceptional care for the affected to prevent adverse effects of the situation they usually encounter. Dementia is a health condition that involves impairments to memory and thinking due to any injury or disease-causing damage to the brain. Older people suffer from different diseases, which cause cognitive disability and long-term ailments and directly affect patients' quality of life. Given the cognitive impairment dementia causes to older people, it is difficult for the care providers to accurately assess the impact on every individual to formulate a person-centered care plan. During the COVID-19 pandemic, due to administrative restrictions on social distancing to prevent transmission of this disease, caregivers and elderly persons feel tremendous mental stress, further aggravating their problems because of loneliness. Thus, there is a requirement to do the study and analyze the effects on older people to provide quality and person-centered care. Due to the above factors as significant challenges in the current context, there is an ardent need for the results of variegated studies besides a thorough analysis of available literature analyzed to provide proper evidence to the care providers. It will pave the way for understanding the actual impact of the condition in its natural context. In this regard, a literature review and the results of the studies are discussed. This research brings into the limelight all those factors in the context of previous studies and data analysis of the current situation.

Exploring the Clinical Utility of the Music Therapy Assessment Tool for Awareness in Disorders of Consciousness (MATADOC) with People with End-Stage Dementia

Dementia is a major health concern globally and cross-culturally with progressive decline in cognition, mobility and communication. There are few interventions for end-stage dementia (ESD) although music interventions have been observed to be accessible for people with mid to late-stage dementia. The lack of protocols and measures suited to ESD has limited research into the effects of music therapy. Measure sensitivity to minimal responsiveness is one limitation to the use of existing music intervention measures with ESD. This exploratory study examined the clinical utility of the Music Therapy Assessment Tool for Awareness in Disorders of Consciousness (MATADOC) for use with people with end-stage dementia, including preliminary reliability and validity. The MATADOC is a standardized assessment for minimally responsive patients with disorders of consciousness and may be useful for ESD. Using repeated measures with blinded MATADOC-trained raters, MATADOC data were collected with a small convenience sample of people with ESD in a residential care setting. Clinical utility data were collected from the raters and evaluated using a multidimensional model. To explore its functionality, MATADOC outcomes were compared to another measure for music interventions in dementia. The MATADOC may be useful for assessing functioning and responsiveness to music interventions for people with ESD without the risk of floor effects. Modifying the MATADOC protocol and assessment documentation prior to testing with a larger sample will enhance its sensitivity specific to ESD and age-related needs, providing a new music-based ESD assessment.

Effects of Reminiscence Therapy on Cognition, Depression and Quality of Life in Elderly People with Alzheimer’s Disease: A Systematic Review of Randomized Controlled Trials

Background: Patients with Alzheimer’s disease (AD) present with cognitive function deterioration, neuropsychiatric symptoms (NPS)—especially depression—and low quality of life (QoL). Management of AD remains difficult, especially in the elderly. Reminiscence therapy (RT) is a well-known cognitive rehabilitation intervention that can be adopted in nursing and residential care homes to restore autobiographical memory, ameliorate NPS, and improve the QoL of people with dementia. However, the evidence-based efficacy of RT for elderly patients with AD remains to be determined. Methods: Here, we synthesized findings of randomized controlled trials (RCTs) exploring the effects of RT on cognition, depression, and QoL in elderly people with AD, according to the most recent PRISMA statement. We searched for RCTs in PubMed, Web of Science, and Cochrane Central Register of Controlled Trials, and in trial registries (i.e., clinicaltrials.gov and International Clinical Trials Registry Platform of the World Health Organization). Two review authors extracted data of interest, with cognition, depression, and QoL measures as outcomes. Results: A total of five articles were included in the final analysis. Findings globally showed that RT, both administered in individual or group sessions at least once a week for 30–35 min over a period of 12 weeks, is effective in supporting global cognition, ameliorating depression, and improving specific aspects of the QoL in elderly people with AD. Conclusions: RT has the potential to be a routine non-pharmacological therapy for elderly people with AD, thanks to its wider effects on the individual in terms of cognitive vitality and emotional status promotion, with positive implications for patient’s daily life. Despite such evidences, caution should be used in findings’ generalizability in relation to the paucity of existing RCTs with long-term follow-up.

Analysing the Quality of Life of Older Adults: Heterogeneity, COVID-19 Lockdown, and Residential Stability

This study aims to, first, investigate the quality of life (QOL) of older adults in Taiwan, from the perspective of heterogeneity and, second, clarify the social isolation affecting their QOL during the pandemic. Additionally, it explores the residential stability of older adults. Our empirical model, a Generalized Ordered Probit Model, uses secondary data from the 2019 Taiwan Social Change Survey for people aged 65 and above, with a total sampling size of 417. The results show that the self-assessed physical health of older adults is a significantly heterogeneous variable affecting their QOL, and has a varying impact on the probability of them being satisfied with their QOL. Results suggest that better financial plans and staying healthy are the main determinants of their QOL. Social isolation during the COVID-19 pandemic significantly hampered their QOL, which was not compensated by the use of the internet. Furthermore, older adults' residential stability significantly influences their QOL. Family members and relevant social work units should contribute to in-person home care for older adults to reduce their social isolation, with a focus on improving their living environments and to ensure that they age in a safe and healthy place.

Quantitative gait analysis in mild cognitive impairment, dementia, and cognitively intact individuals: a cross-sectional case-control study

Background

Cognitive age-related decline is linked to dementia development and gait has been proposed to measure the change in brain function. This study aimed to investigate if spatiotemporal gait variables could be used to differentiate between the three cognitive status groups.

Methods

Ninety-three older adults were screened and classified into three groups; mild cognitive impairment (MCI) (n = 32), dementia (n = 31), and a cognitively intact (n = 30). Spatiotemporal gait variables were assessed under single- and dual-tasks using an objective platform system. Effects of cognitive status and walking task were analyzed using a two-way ANCOVA. Sub-comparisons for between- and within-group were performed by one-way ANCOVA and Paired t-tests. Area Under the Curve (AUC) of Receiver Operating Characteristics (ROC) was used to discriminate between three groups on gait variables.

Results

There were significant effects (P < 0.05) of cognitive status during both single and dual-task walking in several variables between the MCI and dementia and between dementia and cognitively intact groups, while no difference was seen between the MCI and cognitively intact groups. A large differentiation effect between the groups was found for step length, stride length, and gait speed during both conditions of walking.

Conclusions

Spatiotemporal gait variables showed discriminative ability between dementia and cognitively intact groups in both single and dual-tasks. This suggests that gait could potentially be used as a clinical differentiation marker for individuals with cognitive problems.
