Dementia-Friendly Neighborhood and the Built Environment: A Scoping Review

2024 Alzheimer's disease facts and figures

This article describes the public health impact of Alzheimer's disease (AD), including prevalence and incidence, mortality and morbidity, use and costs of care and the ramifications of AD for family caregivers, the dementia workforce and society. The Special Report discusses the larger health care system for older adults with cognitive issues, focusing on the role of caregivers and non-physician health care professionals. An estimated 6.9 million Americans age 65 and older are living with Alzheimer's dementia today. This number could grow to 13.8 million by 2060, barring the development of medical breakthroughs to prevent or cure AD. Official AD death certificates recorded 119,399 deaths from AD in 2021. In 2020 and 2021, when COVID-19 entered the ranks of the top ten causes of death, Alzheimer's was the seventh-leading cause of death in the United States. Official counts for more recent years are still being compiled. Alzheimer's remains the fifth-leading cause of death among Americans age 65 and older. Between 2000 and 2021, deaths from stroke, heart disease and HIV decreased, whereas reported deaths from AD increased more than 140%. More than 11 million family members and other unpaid caregivers provided an estimated 18.4 billion hours of care to people with Alzheimer's or other dementias in 2023. These figures reflect a decline in the number of caregivers compared with a decade earlier, as well as an increase in the amount of care provided by each remaining caregiver. Unpaid dementia caregiving was valued at $346.6 billion in 2023. Its costs, however, extend to unpaid caregivers' increased risk for emotional distress and negative mental and physical health outcomes. Members of the paid health care and broader community-based workforce are involved in diagnosing, treating and caring for people with dementia. However, the United States faces growing shortages across different segments of the dementia care workforce due to a combination of factors, including the absolute increase in the number of people living with dementia. Therefore, targeted programs and care delivery models will be needed to attract, better train and effectively deploy health care and community-based workers to provide dementia care. Average per-person Medicare payments for services to beneficiaries age 65 and older with AD or other dementias are almost three times as great as payments for beneficiaries without these conditions, and Medicaid payments are more than 22 times as great. Total payments in 2024 for health care, long-term care and hospice services for people age 65 and older with dementia are estimated to be $360 billion. The Special Report investigates how caregivers of older adults with cognitive issues interact with the health care system and examines the role non-physician health care professionals play in facilitating clinical care and access to community-based services and supports. It includes surveys of caregivers and health care workers, focusing on their experiences, challenges, awareness and perceptions of dementia care navigation.

Are We Speaking the Same Language? Terminology Consistency in EBD

OBJECTIVE

The aim of this study is to analyze the consistency, variability, and potential standardization of terminology used to describe architectural variables (AVs) and health outcomes in evidence-based design (EBD) studies.

BACKGROUND

In EBD research, consistent terminology is crucial for studying the effects of AVs on health outcomes. However, there is a possibility that diverse terms have been used by researchers, which could lead to potential confusion and inconsistencies.

METHODS

Three recent large systematic reviews were used as a source of publications, and 105 were extracted. The analysis aimed to extract a list of the terms used to refer to the unique concepts of AVs and health outcomes, with a specific focus on people with dementia. Each term's frequency was calculated, and statistical tests, including the χ2 and the post hoc test, were employed to compare their distributions.

RESULTS

The study identified representative terms for AVs and health outcomes, revealing the variability in terminology usage within EBD field for dementia-friendly design. The comparative analysis of the identified terms highlighted patterns of frequency and distribution, shedding light on potential areas for standardization.

CONCLUSIONS

The findings emphasize the need for standardized terminologies in EBD to improve communication, collaboration, and knowledge synthesis. Standardization of terminology can facilitate research comparability, enhance the generalizability of findings by creating a common language across studies and practitioners, and support the development of EBD guidelines. The study contributes to the ongoing discourse on standardizing terminologies in the field and provides insights into strategies for achieving consensus among researchers, practitioners, and stakeholders in health environmental research.

Dementia care and prevention in community settings: a built environment framework for cognitive health promotion

PURPOSE OF REVIEW

Most people with dementia live in the community. As lifespan increases, one in three persons aged 85+ are expected to live with dementia. We conduct a systematic search to identify frameworks for dementia care and prevention in community settings. This is important to ensure quality of life for people living with cognitive decline (PLCD).

RECENT FINDINGS

61 frameworks are synthesized into the dementia care and prevention in community (DCPC) framework. It highlights three levels of provision: built environment and policy supports, access and innovation, and inclusion across stages of decline. Domains of intervention include: basic needs; built environment health and accessibility; service access and use; community health infrastructure; community engagement; mental health and wellbeing; technology; end-of-life care; cultural considerations; policy, education, and resources. Personhood is not adequately represented in current built environment frameworks. This is supplemented with 14 articles on lived experiences at home and social practices that contribute to PLCD's social identity and psychological safety.

SUMMARY

Policy makers, health and built environment professionals must work together to promote "personhood in community" with PLCD. Clinicians and community staff may focus on inclusion, social identity and a sense of at-homeness as attainable outcomes despite diagnosis.

Moderating Role of Neighborhood Environment in the Associations Between Hearing Loss and Cognitive Challenges Among Older Adults: Evidence From US National Study

This study examined the associations between hearing loss and cognitive challenges among community-dwelling older adults and whether neighborhood characteristics (physical disorder and low social cohesion) moderated the associations. Cross-sectional national data from Round 11 of the National Health and Aging Trends Study were adopted (N = 2,515). Multinomial logistic regressions were used to examine associations among variables and interactive analyses were conducted to examine moderating effects. Results indicated significant relationships between the experience of hearing loss and possible dementia and between severe or profound hearing loss and probable dementia. Interactive models suggested that residing in neighborhoods with physical disorder and low social cohesion were negatively associated with possible dementia among older adults with moderate and severe or profound hearing loss, respectively, compared to those without hearing loss. Findings underscore the necessity of environmental and social interventions to enhance cognitive health among older adults with varying degrees of hearing challenges.

Monitoring and Evaluation of Dementia-Friendly Neighborhoods Using a Walkshed Approach: Protocol for a Scoping Review

BACKGROUND

The number of people in society living with dementia is growing. In Canada, most people who live with dementia live at home, often in a neighborhood setting. Neighborhood environments can be a source of independence, social engagement, and well-being. They can also contain barriers that limit physical activity, social engagement, and well-being. A dementia-friendly neighborhood includes assets that support persons living with dementia and their caregivers in multiple life domains, including those that support walking within the neighborhood environment.

OBJECTIVE

The objectives for this scoping review are twofold. First, focusing on walkshed analysis, we aim to extend scholarly understandings of methodological practices used in the monitoring and evaluation of dementia-friendly neighborhoods. Second, we aim to provide clear and practical guidance for those working in planning, design, and public health fields to assess the neighborhood context in support of evidence-based action to improve the lives of persons living with dementia.

METHODS

The study design follows Arksey and O'Malley's scoping review framework and PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols) guidelines. We will conduct a search of peer-reviewed studies in 6 electronic databases to identify the use of Geographic Information System analysis to measure the walkshed of persons living with dementia in a community setting. As age is a primary risk factor associated with dementia, we will also include studies that focus more broadly on community-dwelling older adults aged 65 years and older. Data will be extracted, analyzed, and represented according to 3 domains. This includes study details, walkshed analysis methods, and criteria and indicators used to measure dementia-friendly neighborhoods.

RESULTS

The results of the study and the submission of a manuscript for peer review are expected in June 2024. The results of the review are expected to contribute to an understanding of methods for monitoring and evaluating dementia-friendly neighborhoods. Expected findings will include a detailed breakdown of current parameters and routines used to conduct walkshed analysis. Findings will also convey criteria that can be operationalized in a Geographic Information System as indicators to assess barriers and facilitators to walking in a neighborhood setting.

CONCLUSIONS

As far as we are aware, the proposed scoping review will be the first to provide comprehensive methodological or technical guidance for conducting walkshed analysis specific to persons living with dementia. Both the scalability and objective nature of walkshed analysis are likely to be of direct interest to public health practitioners, planners, and allied professionals. Clearly documenting methods used in walkshed analysis can spur increased collaboration across these disciplines to enable an evidence-informed approach to improving neighborhood environments for persons living with dementia.

Neighborhood resources and risk of cognitive decline among a community-dwelling long-term care population in the U.S

Objective

To examine the associations between neighborhood resources (i.e., number of restaurants, recreation centers, or social services for seniors and persons with disability per land area) and cognitive decline among a community-dwelling long-term care population and whether they differ by baseline cognition status.

Study design

Prospective longitudinal cohort study.

Methods

We used a longitudinal dataset that assessed over a two-year period older adults receiving state-funded home- and community-based services in Michigan Metropolitan areas (N = 9,802) and applied nonlinear mixed models with a random intercept with Poisson distribution.

Results

Cognitively intact older adults were less likely to experience cognitive decline when they resided in resource-rich neighborhoods, compared to those cognitively intact but living in neighborhoods that lacked resources. But their cognitively impaired or dementia-diagnosed counterparts did not similarly benefit from living in neighborhoods with rich resources.

Conclusions

Neighborhood resources may be an important aspect of intervention to mitigate cognitive decline before older adults become cognitively impaired.

"The Dynamic Nature of Being a Person": An Ethnographic Study of People Living With Dementia in Their Communities

BACKGROUND AND OBJECTIVES

A dementia diagnosis can affect social interactions. This study aims to understand how people living with dementia act as social beings within everyday interactions in their local communities.

RESEARCH DESIGN AND METHODS

Focused ethnography informed by Spradley's approach to data collection and analysis. Observations in community spaces.

RESULTS

Twenty-nine observations were undertaken in everyday social settings with 11 people with dementia who were part of a longitudinal interview study. Data consisted of 40 hr of observation, and researcher field notes. The overarching theme "the dynamic nature of being a person" encapsulates participants' exhibited experiences in negotiating to attain and sustain an acknowledged place in their communities. Two subthemes characterized contexts and actions: (1) "Being me-not dementia": Participants constructed narratives to assert their ontological presence in social settings. They and others used strategies to mediate cognitive changes evidencing dementia. (2) "Resisting or acquiescing to 'being absent in place'": Participants were often able to resist being absent to the gaze from others, but some social structures and behaviors led to a person being "in place," yet not having their presence confirmed.

DISCUSSION AND IMPLICATIONS

People living with dementia can actively draw on personal attributes, familiar rituals, objects, and social roles to continue to present themselves as social beings. Identifying how postdiagnosis people may self-manage cognitive changes to retain their presence as a person can help health and social care practitioners and families collaborate with the person living with dementia enabling them to have a continued social presence.

Designing environments that contribute to a reduction in the progression of Parkinson's disease; a literature review

Parkinson's Disease (PD), a prevalent neurological disorder, causes physical difficulties like stiffness and impaired walking and affects patients' emotional well-being. Regular exercise and exposure to enriched environments are crucial to managing these symptoms. This review aims to extract evidence from studies regarding built environments' impact on reducing the progression of PD. Keywords from 2005 to 2022 were used in five databases, including PubMed, Clarivate Web of Science, UGA Library, and Google Scholar. Many studies emphasized physiotherapy and training for physical enhancement, often utilizing virtual games and smart devices. Others highlighted the advantages of non-slip flooring and accessible outdoor spaces, with some based on universal design principles. Few studies considered the emotional impact of built environments, showing a considerable gap in the studies simultaneously evaluating psychological and physical perspectives of Parkinson-friendly environments. There needs to be more consistency when considering these aspects of planning. Our findings suggest future research modeling enriched environments and tracking their impact on patients via Virtual Reality to find a comprehensive guideline for the most effective PD management environments.

Monitoring and evaluation of dementia-friendly neighbourhoods using a walkshed approach: A scoping review protocol (Preprint).. [DOI: 10.2196/preprints.50548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

UNSTRUCTURED

The number of people in society living with Dementia is growing. In Canada, most people who live with dementia live at home, often in a neighbourhood setting. Neighbourhood environments can be source of independence, social engagement, and well-being, but can also contain barriers that limit physical activity, social engagement, and well-being. A dementia-friendly neighbourhood includes assets that support persons living with dementia and their caregivers in multiple life domains, including those that support walking within the neighbourhood environment. The study design follow’s Arksey and O’Malley’s scoping review framework and PRISMA-P guidelines. A search of peer-reviewed studies in six electronic databases will be conducted to identify the use of GIS analysis to measure the walkshed of persons living with dementia in a community setting. Data will be extracted, analyzed and represented according to three domains, including study details, walkshed analysis methods, and criteria and indicators used to measure dementia-friendly neighbourhoods. Results of the review are expected to contribute understanding of methods for monitoring and evaluation of dementia friendly neighbourhoods. Both the scalability and objective nature of walkshed analysis are likely to be of direct interest to public health practitioners and planning and allied professionals.

Variation in Implementing Dementia-Friendly Community Initiatives: Advancing Theory for Social Change

Dementia-friendly communities (DFC) have emerged as a global movement to make communities more supportive and inclusive of people living with dementia (PLWD) and their care partners. This study contributes to a nascent body of research on DFC initiatives by building theory on their local implementation. Based on an analysis of data from semi-structured interviews with 23 leaders of initiatives in Massachusetts (United States), we aimed to identify key dimensions of variation in the implementation of DFC initiatives. We found that all initiatives engaged in a common set of activities, such as the facilitation of training about dementia and improving services for PLWD. Although initiatives mostly engaged in these activities in ways that targeted the community at large, in some instances, they concentrated their efforts on enhancing the dementia-friendliness of their own organizations. We describe ways in which financial, social, and human capital operate as key factors that influence the initiatives' primary focus (i.e., the community at large or their own organization). Our findings suggest the importance of helping DFC initiative leaders more explicitly specify the focal ecological level of their efforts throughout the trajectory of their work, especially in the context of resource considerations. Results also indicate ways in which DFC initiative efforts at one systems level can support those at other levels over time.

Key Considerations When Providing Physical Rehabilitation for People with Advanced Dementia

Dementia is a growing global challenge with numbers set to increase rapidly in the coming years. Evidence suggests that exercise can be effective in improving cognitive functioning, but the evidence does not yet support improvements in other key domains such as quality of life or physical ability. The aim of this study was to explore the key components that needed to be considered when providing physical rehabilitation to people with advanced dementia. The study used a qualitative approach involving semi-structured focus groups with health care professionals who are experts in delivering interventions to people with advanced dementia. As a pragmatic study seeking to inform the development of interventions, a thematic coding approach was used to make sense of the data. We collected data from 20 healthcare professionals who reported that key considerations needed to be considered from both an assessment and an intervention perspective. The assessment needed to be person centred and, with the right people engaged and using outcome measures that were meaningful to the patient. The actual intervention also needed to follow the principles of person-centred care, with emphasis placed on the importance of taking time to build a rapport with the person, but also reducing any of the barriers that would prevent effective engagement, such as unsuitable environments. Our study suggests that while there are barriers and challenges to providing interventions and rehabilitation to people with advanced dementia, appropriate person-centred, tailored interventions can be effective and therefore should be offered.

Neighbourhood walkability in relation to cognitive functioning in patients with disorders along the heart-brain axis

This study examined associations of neighbourhood walkability with cognitive functioning (i.e., global cognition, memory, language, attention-psychomotor speed, and executive functioning) in participants without or with either heart failure, carotid occlusive disease, or vascular cognitive impairment. Neighbourhood walkability at baseline was positively associated with global cognition and attention-psychomotor speed. These associations were stronger in patients with vascular cognitive impairment. Individuals who live in residential areas with higher walkability levels were less likely to have impairments in language and executive functioning at two-year follow-up. These findings highlight the importance of the built environment for cognitive functioning in healthy and vulnerable groups.

Associations between community participation and types of places visited among persons living with and without dementia: risks perception and socio-demographic aspects

Introduction

Increasingly, literature has focused on community participation in places visited by persons living with and without dementia. Earlier research indicates that multiple factors, including socio-demographic aspects and risk perception may influence community participation.

Aim and methods

This cross-sectional, explorative study aims to inquire into how places visited, socio-demographic aspects and risks perception are associated with self-rated community participation for persons living with and without dementia (n = 70) in Switzerland. Data was collected through face-to-face interviews with questionnaires (ACT-OUT, MoCA, sociodemographic). First, we investigated whether the number of places visited was correlated with self-rated participation; then we added socio-demographic and risks perception factors with a bivariate analysis; and searched for a model using multinomial logistic regressions.

Results

For the group of participants living with dementia, risks of falling (p = .014) and of getting lost (p = .037) were significantly associated with self-rated participation. For the group of participants living without dementia, visiting places outside the home was significantly associated with self-rated participation, especially visiting places in domain D/places for recreational and physical activities (p = .005).

Discussion and conclusions

The results of exploring multiple factors and searching for a model highlights the complexity of community participation as a construct. Risks and visiting places for recreational and physical activities seem to play a role in self-rated participation. Mobile interviews might be better suited to gain in-depth understanding on community participation for persons living with dementia.

Association between housing type and accelerated biological aging in different sexes: moderating effects of health behaviors

Introduction: Despite associated with multiple geriatric disorders, whether housing type, an indicator of socioeconomic status (SES) and environmental factors, is associated with accelerated biological aging is unknown. Furthermore, although individuals with low-SES have higher body mass index (BMI) and are more likely to smoke, whether BMI and smoking status moderate the association between SES and biological aging is unclear. We examined these questions in urbanized low-SES older community-dwelling adults.

Methods: First, we analyzed complete blood count data using the cox proportional hazards model and derived measures for biological age (BA) and biological age acceleration (BAA, the higher the more accelerated aging) (N = 376). Subsequently, BAA was regressed on housing type, controlling for covariates, including four other SES indicators. Interaction terms between housing type and BMI/smoking status were separately added to examine their moderating effects. Total sample and sex-stratified analyses were performed.

Results: There were significant differences between men and women in housing type and BAA. Compared to residents in ≥3 room public or private housing, older adults resided in 1–2 room public housing had a higher BAA. Furthermore, BMI attenuated the association between housing type and BAA. In sex-stratified analyses, the main and interaction effects were only significant in women. In men, smoking status instead aggravated the association between housing type and BAA.

Conclusion: Controlling for other SES indicators, housing type is an independent socio-environmental determinant of BA and BAA in a low-SES urbanized population. There were also sex differences in the moderating effects of health behaviors on biological aging.

The influence of the built environment in enacting a household model of residential aged care for people living with a mental health condition: A qualitative post-occupancy evaluation

This study undertakes a spatial analysis of an Australian aged care setting where residents receive person-centred support in a specially-designed home-like environment. Focus groups were conducted with staff to explore the impact of the built environment in a new residential aged care setting that has implemented a Household Model of care for people living with mental health conditions. Drawing on Actor-Network Theory and proxemics, we mapped how the built environment supports improved behaviours and care practices in four areas: food preparation and dining, sleep and self-care, site layout, and relationships.
