What does the general public understand about prevention and treatment of dementia? A systematic review of population-based surveys

Effectiveness of the Interdisciplinary Home-bAsed Reablement Programme (I-HARP) on improving functional independence of people living with dementia: a multicentre, pragmatic, randomised, open-label, controlled trial

BACKGROUND

We investigated the effectiveness of an Interdisciplinary Home-bAsed Reablement Programme (I-HARP) on improving functional independence, health and well-being of people with dementia, family carer outcomes and costs.

METHOD

A multicentre pragmatic parallel-arm randomised controlled trial compared I-HARP to usual care in community-dwelling people with mild to moderate dementia and their family carers in Sydney, Australia (2018-2022). I-HARP is a 4-month, home-based, dementia rehabilitation model delivered by an interdisciplinary team. Assessments were conducted at baseline (time-1), 4-month (time-2) and 12-month (time-3) follow-up. The primary outcome measure was the client's functional independence using the Disability Assessment for Dementia (DAD) scale at time-2, based on intention-to-treat analyses.

RESULT

Of 130 recruited client-carer dyads, 116 dyads (58/group) completed the trial. The I-HARP group were not significantly better in most outcome measures than usual care at both time-2 and time-3; with the only statistically significant difference being a reduction in home environment hazards at time-2. Post hoc subgroup analysis of 66 clients with mild dementia found significantly better functional independence in the intervention group compared with those in usual care: difference 8.99 on DAD (95% CI 1.21, 16.79) at time-2 and difference 12.16 (95% CI 1.93, 22.38) at time-3. Economic evaluation suggests potentially lower resource use in I-HARP compared with usual care, but the cost-effectiveness is uncertain.

CONCLUSION

Primary outcomes were not met for a population of people with dementia, with severity ranging from mild to moderate and severe. The I-HARP model appeared to benefit functional independence of participants with mild dementia, with potential cost savings.

Barriers for access and utilization of dementia care services in Europe: a systematic review

BACKGROUND

Dementia is a group of chronic diseases characterised by cognitive impairment that progressively disrupts daily functioning and requires increasing levels of healthcare, social support, and long-term care. Support for people with dementia can be provided by formal support systems although most of the care process relies upon informal care givers. Despite the availability of formal support systems and healthcare workers, the utilization of dementia care services remains suboptimal. Factors such as non-compliance, lack of awareness, and poor care coordination contribute to this issue. Understanding these barriers is crucial for improving service utilization and alleviating the economic burden on families and national health systems.

METHODS

This systematic review analysed the literature, published from 2013 to 2023, on barriers in Alzheimer and other dementia healthcare system, conducted on people living with a dementia, their caregivers, or healthcare workers in dementia care settings in Europe, following PRISMA guidelines. Searches in PubMed, Embase, PsycINFO, Health Technology Assessment Database, and Web of Science used terms related to Alzheimer's, dementia, and access barriers. Rayyan AI supported full-text review, with quality assessed via the Mixed Methods Appraisal Tool.

RESULTS

Over 1298 articles, 29 studies met the inclusion criteria. These studies highlighted several barriers to dementia care, categorised into information, organizational, cultural, stigma-related, financial, and logistical challenges. Informational and educational barriers included a lack of awareness and knowledge among caregivers. Organizational barriers involved poor care coordination and unclear access procedures. Cultural and stigma-related barriers were linked to societal attitudes towards dementia. Financial barriers were associated with the high costs of care, and logistical barriers included limited availability and accessibility of support services.

CONCLUSIONS

To enhance the quality of life for individuals living with dementia, it is crucial to address these identified barriers through tailored interventions and management programs. Improving care coordination, communication, and training for healthcare professionals, alongside reducing systemic delays, are essential steps toward more effective dementia care. Easing the burden of care with tailored interventions and management programmes is mandatory to improve the quality of life of persons living with dementia and their families.

"Infographing" Dementia Prevention: A Co-Design Approach

Designing effective public health messages is challenging, particularly when communicating complex and relatively new health messages such as dementia risk prevention which are still largely unfamiliar to the public. The accessibility of these messages, especially for individuals who speak English as an additional language, remains uncertain in large scale educational interventions. A key strategy to enhance the communication of evidence-based information is to co-design infographics that optimize the accessibility and impact of visual health messages. This paper reports on the co-design process of infographing dementia prevention messages. Qualitative data were analyzed using reflective thematic analysis to generate three themes reflecting the message design preferences of participants: "all hands on deck," "charting the course," and "get on board." This work supports the crucial need to engage the target audience via co-design when creating visual messages as meaningful and accessible educational tools that will resonate with the intended audience. Doing so may help health communicators navigate the creation of visual messages across diverse health domains and populations.

Tailoring implementation strategies for the healthy actions and lifestyles to Avoid Dementia or Hispanos y el ALTo a la Demencia Program: Lessons learned from a survey study

BACKGROUND

Healthy Actions and Lifestyles to Avoid Dementia Program (HALT-AD) or Hispanos y el ALTo a la Demencia is a recently-developed online educational platform to help individuals identify and modify their own dementia modifiable risk factors (MRF). In light of known challenges in recruiting and retaining diverse participants in research studies, there is a need to identify data-informed strategies that will contribute to effective outreach and tailored implementation of HALT-AD among its intended users of Hispanic and non-Hispanic midlife and older adults in the US.

OBJECTIVES

To identify factors (i.e, demographic, medical, psychosocial and environmental) that may facilitate or impede effective program enrollment and participation.

DESIGN

Cross-sectional study SETTING: Data from an online and self-administered survey conducted between January and April 2023 PARTICIPANTS: Residents of California, predominately San Diego, who were 50 to 85 years old, with no dementia or Alzheimer's disease, proficient in English or Spanish and with enough technical ability to complete the survey electronically (n=157; 43% Hispanic). INTERVENTION (IF ANY): none MEASUREMENTS: RedCap was used to capture answers to closed and open-ended survey questions. Mixed-methods analysis was used: For quantitative data, descriptive statistics, comparisons by group (Hispanic/non-Hispanic), and exploratory factor analysis were conducted in SPSS. Thematic analysis with open coding in Excel was used for qualitative responses.

RESULTS

Independent of ethnicity, participants' most preferred method of reach for recruitment was through a conversation with their doctor or with a family member or friend. Their least preferred method was receiving a Facebook advertisement especially among non-Hispanics. Interest in program participation did not differ by sociodemographic characteristics or self-rated satisfaction with individualized MRFs. Instead, having higher confidence in one's ability to commit to behavior change was significantly associated with higher interest in program participation. While a common theme to motivate both groups to participate was the potential to decrease dementia risk, non-Hispanics were motivated by the premise of supporting research and having a positive user experience. For program implementation, Hispanics were more likely to be interested in participating if live sessions, either online or in-person, were provided to offer support with making lifestyle changes as adjunct to completing online courses independently. In both groups, participation may be further facilitated by offering wearable devices which provide participants with feedback on lifestyle change progress.

CONCLUSIONS

A "one-size-fits-all" approach to recruitment and implementation of HALT-AD may not be effective in enrolling and retaining participants in future studies or for clinical use. Instead, a tailored approach that accounts for personal and ethnically-dependent preferences may be more beneficial.

Gaps in dementia knowledge: a nationwide study of public awareness and misconceptions in Bulgaria

BACKGROUND

Dementia is a global health concern which can be mitigated by primary prevention and improved literacy. Effective educational initiatives are informed by studies of dementia knowledge. However, most of these studies are conducted in high-income countries, leaving the Balkan region underrepresented. This study aimed to conduct the first investigation of dementia knowledge among the Bulgarian population, exploring recognition of symptoms, general dementia knowledge, and risk factors awareness.

METHODS

Using an online survey we assessed the following components of knowledge: (i) recognition of dementia symptoms from a vignette; (ii) dementia literacy measured with the Dementia Knowledge Assessment Scale (DKAS); and (iii) knowledge about dementia risk factors. Demographic characteristics, previous experience with dementia, and patterns of informing about dementia were also considered in the study.

RESULTS

One thousand, eight hundred and ninety-six adults (mean age = 44.99; 51.79% female) completed the survey. Half of the respondents correctly recognised dementia symptoms from a vignette. The average DKAS score was 9.51. Dementia knowledge was linked to education, marital status, employment, ethnicity, experience with dementia, and informational sources. 56.7% of the respondents thought dementia was a normal part of ageing and 74.8% did not know a healthy lifestyle reduces the risk of dementia. The average number of identified risk factors was eight (out of 17), with many mistakenly citing dental fillings, laziness, and witchcraft as contributors to dementia.

CONCLUSIONS

The Bulgarian society has a poor understanding of dementia, highlighting the need for improved awareness and education. Policy-makers should prioritise dementia as a social issue and take coordinated actions to educate society and eradicate harmful misconceptions.

Factors Associated With Life Satisfaction Among Veterans Enrolled in the Healthy Aging Project-Brain (HAP-B) Psychoeducational Class

Healthy Aging Project-Brain (HAP-B) is a novel clinical psychoeducation offering developed to encourage engagement in activities associated with successful aging. HAP-B targets sleep, socialization, physical, and cognitive activity through myth-busting, developing SMART goals, and tracking behavioral change. Study aims: (1) assess feasibility/acceptability in a Veteran population; (2) analyze pre- and post-intervention ratings to examine health and well-being; (3) explore associations between health factors and life satisfaction. The 50 participants (mean age = 70.6 years) were predominantly male-identity (88%) and White (76%). Findings, based on independent t tests, revealed improvements in life satisfaction, emotional well-being, and energy levels post-intervention. Linear regression results found higher life satisfaction was associated with lower depressive symptoms, higher emotional well-being, and higher self-efficacy. This easily implementable education intervention can result in more positive self-appraisal with encouraging downstream effects. Healthcare providers are well-positioned to utilize classes such as HAP-B to promote patient-centric approaches to brain health.

Exploring brain health awareness and dementia risk in young adults: A focus group study

OBJECTIVE

The topic of brain health across the life-course is currently receiving exponential attention. Alongside this, exposure to lifestyle-related risk factors for Alzheimer's disease and related dementias accumulates across the life-course. This study aimed to explore young adults' (18-39 years) perceptions and understanding of brain health and dementia risk.

STUDY DESIGN

This study employed a phenomenological descriptive qualitative methodology to examine the lived experiences and perceptions of participants.

METHODS

Focus groups were conducted with 39 young adults (18 female, 2 non-binary) from North America (n = 20) and Europe (n = 19), conducted via video conference.

RESULTS

Participants' awareness and understanding of brain health and dementia risk factors varied, influenced by factors such as general health, family history of dementia, and personal experiences with brain health issues (e.g., traumatic brain injury). The data revealed rich insights into how participants connected (or did not connect) lifestyle factors to brain health and dementia risk.

CONCLUSION

This study is among the first to explore young adults' perceptions of brain health across diverse populations. While participants demonstrated moderate awareness of factors affecting brain health, they often struggled to link these factors directly to dementia risk or protective measures.

Examining the prevention approach in National Dementia Plans from European and North American countries

Objectives

This paper aims to provide a comprehensive review of National Dementia Plans (NDPs) from selected European and North American countries, focusing on the distinct prevention strategies outlined and the approaches employed for reducing dementia risk.

Method

The sample consisted of 16 NDPs from Austria, Canada, Finland, France, Germany, Greece, Ireland, Italy, Liechtenstein, Luxembourg, Malta, the Netherlands, Spain, Switzerland, the UK, and the USA. These NDPs were retrieved from the Alzheimer's Disease International (ADI) database, with regular updates checked on official governmental websites. A qualitative analysis was conducted to identify common themes related to the vision, goals, and corresponding actions and measures within these strategies.

Results

Our analysis revealed that dementia prevention is a strategic goal for most of the countries studied. Common actions identified include the identification of risk factors, advancing research, promoting healthy aging, increasing public awareness, and encouraging lifestyle interventions.

Conclusion

We discuss the limitations and challenges of these actions, and more broadly, of the NDPs in relation to the recent literature on the most effective approaches to preventing dementia. We suggest adopting a more "horizontal" approach to dementia prevention, which current NDPs overlook in favor of "vertical" paradigms.

Sociodemographic and health predictors of adherence to self-administered computerized cognitive assessment

Introduction

Cognitive assessment is essential to detect early cognitive decline and guide interventions. Self-administered computerized assessment is a promising option for periodic cognitive screening in the general population. One of the most critical challenges to implementing cognitive screening in at risk populations is participants' adherence. However, there is insufficient evidence to determine which factors are essential for adherence to long-term digital cognitive screening.

Aims

This study aims to investigate potential sociodemographic and health predictors of adherence to a self-administered web-based cognitive monitoring, the Brain on Track (BoT), in the general population.

Methods

Participants (n = 347) were recruited from the general community. The participants were asked to perform one BoT test every 3 months for cognitive screening and were followed at two time points, namely, 1-year and 3- to 6-year follow-up. Regression models were used to investigate sociodemographic and health predictors of adherence to BoT use at 1 year and up to 6 years.

Results

Being older positively affects adherence to periodic cognitive screening for both follow-up periods. Being a female, having more years of formal education, presenting more BoT baseline correct answers and fewer BoT baseline incorrect answers, and reporting memory complaints positively affect adherence to periodic screening at 3 to 6 years of follow-up but not at 1-year follow-up.

Discussion

The identified determinants of adherence can be considered when planning long-term cognitive screening protocols to increase adherence. Specific strategies could be helpful to improve the adherence of participants who adhere less.

Systematic review of what people know about brain health

OBJECTIVES

As we age our cognitive abilities can change. However, the degree of change experienced is influenced by a range of factors. To understand what the public know about risk and protective factors for cognitive ageing, a systematic review was conducted of studies considering what people know about brain health.

METHOD

The search strategy included quantitative and qualitative studies in English, including interviews, focus groups, questionnaires, surveys of beliefs about brain health (including predictions, opinions) in generally healthy adults. PubMed, PsycINFO, Scopus, and Web of Science were used for published peer-reviewed literature; and ProQuest Dissertations and Theses and National Grey Literature Collection, PsycExtra and Google searches for grey literature.

RESULTS

From 37,197 records, one hundred and one were included, comprising 71 quantitative (22 grey literature), 27 qualitative (1 grey literature) and 3 mixed-methods (1 grey literature). Studies were grouped into three themes: Concerns about cognitive ageing, Opportunities to promote brain health and Understanding dementia risk reduction and prevention.

DISCUSSION

Studies reported varying levels of knowledge of brain health, alongside some suggestions for brain health that were somewhat superficial and not always consistent with scientific consensus. There were differences between groups of participants who exhibited less knowledge of brain health, for example, men, older adults, those with lower education and incomes, and ethnic minorities. This review highlights the need for clear messaging around opportunities to promote brain health, including scientifically-endorsed lifestyle factors and more information on the mechanisms by which they operate.

Establishing a unified global framework for studying dementia knowledge: insights from a narrative review

BACKGROUND

With the global population aging rapidly, dementia has become a pressing public health challenge, affecting the cognitive functions and daily activities of older adults worldwide. Enhancing literacy about dementia is a proactive prevention strategy, yet the effectiveness of educational programs can vary based on the target population's background. Thus, understanding dementia knowledge levels across different communities and countries is essential for successful educational interventions. Despite the large аmount of studies, there is no common framework for studying dementia knowledge, leading to significant variability in methods and poor data comparability.

METHODS

A narrative review is conducted to examine the methodological variability in studies of dementia knowledge and to propose a unified framework for future investigations. We hypothesize that significant differences will be evident in the methodologies employed, particularly regarding knowledge domains, research designs, influencing factors, and assessments of attitudes toward dementia.

RESULTS

A total of 59 research publications published after 2000 were selected, revealing significant variability in approaches to studying dementia knowledge and confirming our hypothesis. We identified eight dementia knowledge domains and various sociodemographic and experiential correlates, along with commonly used complementary assessments. These findings were organized into a unified global framework comprising two core components-dementia knowledge domains and correlates-supplemented by a component addressing affective dispositions towards dementia and an action list to guide future research. The framework aims to provide a foundational basis for enhancing inter-study comparisons and deepening our understanding of dementia knowledge and attitudes across diverse communities.

CONCLUSION

Aligning methodologies for surveying dementia knowledge through a common framework can empower stakeholders to implement effective educational programs, fostering an informed and supportive environment for individuals affected by dementia.

"How will I ever know I didn't bring it on myself?": Navigating personal responsibility in public health messaging on dementia risk

BACKGROUND AND OBJECTIVES

Public health messaging increasingly emphasizes the importance of "lifestyle interventions" to reduce dementia risk. Our study aimed to understand how people interpret and respond to information about dementia risk. In a second sub-aim, we examined how these interpretations may contribute to dementia-related lifestyle stigma.

RESEARCH DESIGN AND METHODS

We engaged in a secondary analysis of 50 semi-structured interviews using a framework approach to understand, from the perspective of community-dwelling middle-aged and older adults, how they may interpret, make sense of, and respond to information about dementia risk and risk reduction. During the interpretive and narrative phase, the authors began to elucidate participant responses analytically and identified that these responses could be interpreted within the health locus of control literature.

RESULTS

Of the 23 participants who discussed dementia risk, 13 felt some sense of personal responsibility and control over their dementia risk. Of those 13, four participants believed they had personal responsibility and control and actively engaged in lifestyle interventions. The remaining nine participants also engaged in lifestyle interventions, aiming to find comfort in knowing they had done what they could to reduce their risk and working to alleviate self-attribution of blame if diagnosed with dementia.

DISCUSSION AND IMPLICATIONS

The tendency to internalize responsibility may inadvertently contribute to the stigmatization of dementia as a 'lifestyle disease' creating dementia-related lifestyle stigma. Recognizing the multifaceted nature of dementia risk, including environmental and external factors beyond individual control, is essential to combatting the 'lifestyle stigma' increasingly associated with the condition.

What does the public really know about dementia? A community-based cross-sectional survey in Turkiye

Despite the increasing burden of dementia, there has been no evaluation of the level of dementia knowledge among the general public in Turkiye. Thus, this study aimed to evaluate the public's knowledge regarding dementia and the factors predicting this knowledge. This is a community-based cross-sectional study. A survey was conducted with 1106 participants between April and August 2023. The research tools were demographic characteristics form, a Turkish version of the dementia knowledge assessment scale (DKAS-T), and a form focusing on sociodemographic information and questions related to the degree of dementia knowledge. The data were analyzed using descriptive statistics, correlation, and multiple regression. The mean score on the DKAS-T was 12.32 ± 6.05 (min: 0 points, max: 33 points) out of 34. The sample recorded an incorrect response for less than half of the items in the dementia knowledge scale. Adjusted R2 was used as explanatory power. Moreover, the results of the multiple regression analysis identified various factors that significantly predicted dementia knowledge scores: age, prior education about dementia, experience of caring for a PwD, interaction with a PwD, and self-reported risk of being diagnosed with dementia in the future. These variables accounted for 18.1% of the total variance of dementia knowledge. Dementia is not well known in the public. The finding underscores the need for targeted educational initiatives to enhance dementia knowledge in the Turkish population. Interventions should focus on addressing specific areas of deficiency identified in the DKAS-T.

Effects of Health Responsibility Frames on Attributions, Emotions, and Social Support Intentions in the Context of Dementias

When news stories cover health and diseases, they often address issues of responsibility. These responsibility frames can affect recipients' responsibility beliefs (i.e., attributions) and thereby affect emotions and motivations to support people affected by health problems. To date, it is not fully understood how responsibility frames affect these attributions, emotions, and social support intentions in the context of dementia. In an online experiment with N = 1,059 German participants, we tested the effects of different responsibility frames (individual vs. contextual) on social support intentions through responsibility attributions and emotional reactions in the context of dementia. Results show that responsibility frames affect responsibility attributions and social support intentions. Mediation analysis shows that the effect of contextual responsibility frames on social support intention is partially mediated by responsibility attribution and emotions (sympathy and anger). We discuss these findings considering framing effects research and media coverage.

Regional health priorities for dementia: a roadmap for the Western Pacific

In the Western Pacific Region, the prevalence of dementia is expected to increase, however, the diversity of the region is expected to present unique challenges. The region has varying levels of preparedness, with a limited number of countries having a specific national dementia plan and awareness campaigns. Diversity of risk and healthcare services within the region is exerting impact on diagnosis, treatment, care, and support, with most countries being under resourced. Similarly, the ability to monitor dementia-related indicators and progress research, particularly relating to treatment and clinical trial access needs to be addressed. Countries require comprehensive national plans that lay out how resources will be allocated to improve dementia literacy, train, and support carers, mobilise resources to reduce risk factors and improve research capabilities. These plans need to be informed by consumers and tailored to the region to develop an inclusive society for people living with dementia and their families.

Risk factors for the neurodegenerative dementias in the Western Pacific region

The Western Pacific Region (WPR) is characterized by a group of socioeconomically, culturally, and geopolitically heterogenous countries and represents a microcosm of the global endemic of neurodegeneration. This review will chart the known risk factors for dementia across the WPR. We explore the intersection between the established risk factors for dementia including the biomedical and lifestyle (cardiovascular and metabolic disease, sleep, hearing loss, depression, alcohol, smoking, traumatic brain injury, genetics) and social determinants (social disadvantage, limited education, systemic racism) as well as incorporate neuroimaging data, where available, to predict disease progression in the WPR. In doing so, we highlight core risk factors for dementia in the WPR, as well as geographical epicentres at heightened risk for dementia, to orient future research towards addressing these disparities.

Knowledge of dementia and Alzheimer's disease among healthcare professionals in Peru

BACKGROUND

 Primary care physicians and other healthcare providers report feeling unprepared to treat persons with dementia (PWD), especially in developing countries OBJECTIVE:  We aimed to assess the knowledge of dementia and Alzheimer's disease (AD) among health professionals in both primary and tertiary care in Peru.

METHODS

 We conducted an in-person and virtual survey of healthcare professionals trained in Peru throughout the year 2020. The survey was developed based on a previously published one and reviewed by an expert panel. We compared groups using a Chi-squared test. A Bonferroni corrected p-value of 0.008 was used for statistical significance.

RESULTS

 Out of 804 surveys, we excluded 56 due to incomplete data. A total of 41.6% of respondents were doctors and 21.8%, nurses. One fifth of participants did not recognize AD as a cause of dementia and over half considered "senile dementia" a valid clinical entity. Scores were higher among those with postgraduate training, multiple patients with dementia, or those who had practiced for over 10 years.

CONCLUSION

 There is a low level of knowledge of dementia and AD among health professionals in Peru, which worsens outside of Lima. Pernicious ideas, such as senile dementia, are still significantly present among respondents.

General practitioners' perspectives on lifestyle interventions for cognitive preservation in dementia prevention

BACKGROUND

General practitioners (GPs) play a crucial role in identifying cognitive impairment and dementia and providing post-diagnostic care. This study investigates (1) how promising GP consider lifestyle changes to maintain cognitive performance in general, (2) GP beliefs about the power of modifiable health and lifestyle factors to maintain cognitive performance, and (3) whether those beliefs vary by GP age.

METHODS

As part of the AgeWell.de trial, GPs (n = 72) completed a process evaluation questionnaire assessing their perspectives on lifestyle changes to preserve cognitive performance in elderly patients. In greater detail, their perceived efficacy of established risk and protective factors was investigated using a 5-point Likert scale. Descriptive statistical analyses were performed for research question (1) and (2). Spearman´s rank correlations and ordinal logistic regressions were used to answer research question (3). All results were interpreted exploratively.

RESULTS

GPs rated the overall chance of lifestyle changes maintaining cognitive performance quite neutral with a median score of 3.0 (IQR = 2.0). They rated the efficacy of all the modifiable health and lifestyle factors high, with increase in physical and social activity ((Mdn = 5.0, IQR = 1.0) receiving the highest ratings with the narrowest range. Spearman's rank correlation indicated a significant positive relationship between age and the belief in "Optimization of nutrition" for preventing cognitive decline and dementia (ρ = .255, p = .041). However, ordinal logistic regressions showed no significant relationships between age and GP ratings of lifestyle change efficacy.

CONCLUSION

These findings highlight the positive perception of GPs on the efficacy of modifiable health and lifestyle factors for preventing cognitive decline and dementia.

TRIAL REGISTRATION

The AgeWell.de trial is registered in the German Clinical Trials Register (DRKS; trial identifier: DRKS00013555, Registration Date 07 December 2017).

"Establishing healthy habits and lifestyles early is very important": parental views of brain health literacy on dementia prevention in preschool and primary school children

Introduction

Parents have the potential to drive healthy lifestyle behaviors through educational initiatives. This study aims to understand the prevalent thoughts and perceptions parents have toward brain health educational programs for preschool and primary school settings, whilst also contributing to a comprehensive understanding of the role parents can play in the broader context of dementia reduction strategies and the cultivation of brain health awareness among children.

Methods

Parents with children aged between 2 and 11 years old were interviewed about their current knowledge of dementia, prior beliefs, current lifestyle factors and opinions on educating their children from a young age on the topic of dementia literacy. Thematic deductive analysis was employed to systematically categorize and interpret the qualitative data obtained from these interviews.

Results

Thirty parents (M age = 38.6, SD = 4.9, Range = 32-48) identified three core themes on nurturing bodies and minds (e.g., conceptualizing the link between intellectual engagement, continuous learning, and the prevention of cognitive decline), brain health literacy (e.g., current knowledge and awareness of brain health, dementia and associated stigma, and provision of age-appropriate health literacy) and parental concerns (i.e., barriers to initiating conversations about dementia with children and strategies to address and alleviate parental concerns). Parents possessing prior knowledge of dementia and its modifiable risk factors exhibited greater propensity to educate their children on the associated risk factors.

Conclusion

Our study highlights the vital influence of parents' experiences, health literacy, and education on the acceptance of brain health education for children. Future interventions should target stigma reduction, enhance awareness, and offer accessible information on modifiable dementia risk factors, enabling a conducive environment for active parental involvement in educating children about brain health and contributing to future well-being.

Knowledge, Awareness, and Perceived Threat Toward Alzheimer's Disease Among the Family Caregivers of Individuals with Chronic Physical Conditions in Bangladesh

Background

Alzheimer's disease (AD) is a growing public health concern affecting millions of individuals worldwide. This disease burden is exacerbated in countries like Bangladesh, where public awareness and knowledge about the condition remains limited.

Objective

This study aimed to assess the level of AD knowledge, awareness, and perceived threat among family caregivers of individuals with chronic physical conditions of Bangladesh.

Methods

A descriptive cross-sectional study was conducted among the caregivers of patients selected via convenience sampling in six public hospitals between October 2022 and March 2023. The data was collected via face-to-face interviews employing a semi-structured questionnaire that contained information about socio-demographic characteristics, personal experiences with AD, knowledge of AD, level of awareness regarding AD, and perceived threat toward AD.

Results

The findings revealed a poor knowledge of AD among the study participants. Regarding AD awareness, 52.5% considered memory loss in older individuals abnormal, 26.2% attributed AD to causes like black magic, psychological distress, or bad eyes. Regarding perceived threat, 60.2% wanted to assess their AD risk, while 68.2% disagreed with the likelihood of developing the disease. Multiple linear regression analysis revealed that age, place of residence, education, and employment status significantly contribute to AD knowledge scores.

Conclusions

This study highlights the urgent need for public education and awareness campaigns to address the knowledge gap and reduce stigmatization associated with AD in Bangladesh. Targeted efforts, particularly among older age groups and rural communities, can enhance understanding and improve the quality of care and support for AD patients and their caregivers.

Facilitators and barriers of help-seeking for persons with dementia in Asia-findings from a qualitative study of informal caregivers

Background and aim

The deterioration in cognition of persons with dementia (PWD) makes their caregivers key players in their help-seeking process. This study aimed to identify the facilitators and barriers of help-seeking for persons with dementia in Asia from the perspective of their informal caregivers.

Methods

A qualitative methodology was adopted in the current study. Twenty-nine informal caregivers of PWD in Singapore were interviewed between April 2019 and December 2020. All interviews were audio-recorded and transcribed verbatim for the analysis.

Results

The transcripts were analyzed using inductive thematic analysis. The results revealed four major themes with 12 sub-themes, including (1) Barriers to diagnosis-seeking (i.e., lack of knowledge and awareness of dementia, emotional denial, resistance from PWD, and delays in the healthcare system); (2) Facilitators of diagnosis-seeking (i.e., synergy between awareness of dementia and an active diagnosis-seeking intention and incidental diagnosis resulting from seeking treatment for comorbid conditions); (3) Barriers to treatment-seeking (i.e., challenges from PWD and disease, challenges faced by caregivers when seeking treatment for PWD, and challenges imposed by the COVID-19 pandemic); (4) Facilitators of treatment-seeking (i.e., caregivers' capabilities of handling PWD, cooperation/compliance from PWD, and an integrated care plan for PWD).

Conclusion

The findings highlight the importance of raising public awareness, enabling health professionals to tailor psychosocial interventions better, and improving community support through dementia awareness and education.

Awareness, attitudes, and beliefs of dementia in Indonesia

INTRODUCTION

Tackling dementia stigma is a policy priority. In Indonesia, we have little insight into the general public's knowledge and attitudes about dementia.

METHODS

Cross-sectional study of 4430 Indonesian adults recruited from Jakarta and North Sumatra, Indonesia. Measures included dementia knowledge and attitudes.

RESULTS

A total of 86.3% (n = 3,803) of adults had not heard of the terms dementia or Alzheimer's disease, and commonly viewed dementia as a normal part of aging. Being older, incorrect knowledge about etiology, not having heard of the terms dementia and/or Alzheimer's disease, having less than primary education, and being from North Sumatra were associated with more negative attitudes (p-values < 0.05).

DISCUSSION

Misconceptions and lack of awareness about dementia are common in Indonesia. Attitudes tended not to be negative, but our research highlights factors associated with dementia attitudes. Future research should use this information to better tailor and target potential anti-stigma strategies.

Highlights

Most Indonesians had not heard of the terms dementia and/or Alzheimer's disease and thought it was caused by normal aging.The majority of participants held mixed or positive attitudes towards dementia.A series of demographic factors alongside poor awareness were associated with negative attitudes towards dementia.

Increasing awareness for dementia risk reduction through a public awareness campaign in Denmark: A pre-post study

OBJECTIVE

It is estimated that about 40% of all dementia cases are potentially attributable to modifiable risk factors, but awareness of this is relatively lacking.

METHODS

An 18-months nation-wide public awareness campaign on dementia risk reduction was rolled out in Denmark that combined a mass-media approach with an online risk assessment tool and knowledge bank targeting all inhabitants aged between 40 and 75 years. Campaign effects (increase in awareness and knowledge of modifiable dementia risk and protective factors) were assessed via online surveys in two independent random samples before (n = 1003) and after the campaign (n = 1076).

RESULTS

After adjusting for differences in educational level between the two samples, there was no significant difference in awareness of dementia risk reduction between the pre-campaign (66.5% aware) and post-campaign (63.4% aware) sample (probit z = -0.08, p = 0.151). The number of correctly identified risk/protective factors was significantly higher in the post-campaign sample. After adjusting for potential confounding factors, self-reported exposure to the campaign was associated with more awareness, better recognition of risk/protective factors, more motivation for and actual implementation of lifestyle changes.

CONCLUSIONS

This mass-media campaign did not increase overall awareness that dementia risk is partly modifiable. However, exposure to the campaign was associated with more awareness and willingness to take action to improve brain health. Future campaigns should tailor messages to specific subgroups to broaden the reach (e.g., males), co-create materials with the target group, and give special attention to the contribution of metabolic/cardiovascular risk factors to dementia risk.

Validity and Reliability of the Turkish Version of the Behavioral and Psychological Symptoms of Dementia Knowledge Scale (BPSD-T): A Psychometric Evaluation Among Caregivers

OBJECTIVE

This study aimed to validate the Turkish version of the Behavioral and Psychological Symptoms of Dementia Knowledge Scale (BPSD-T) among caregivers. The goal was to assess the scale's psychometric properties, ensuring it accurately measures caregivers' knowledge of dementia-related behavioral and psychological symptoms in a Turkish context.

METHODS

In this cross-sectional study, the data were collected from 212 caregivers providing home-based care to dementia patients across Turkey. Participants completed a 12-item Behavioral and Psychological Symptoms of Dementia (BPSD) knowledge questionnaire along with a sociodemographic form. To examine the factor structure of the scale, both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were conducted. Sample adequacy for EFA was assessed using the Kaiser- Meyer-Olkin (KMO) measure and Bartlett's test of sphericity. For CFA, model fit was evaluated using fit indices such as χ2/df, Goodness of Fit Index (GFI), Comparative Fit Index (CFI), Normed Fit Index (NFI), and Root Mean Square Error of Approximation (RMSEA). The internal consistency of the scale was assessed with Cronbach's alpha coefficient.

RESULTS

The findings showed that the BPSD-T has strong internal consistency (Cronbach's alpha=0.85) and a robust factor structure. Factor loadings ranged from 0.396 to 0.744, supporting the construct validity of the scale. Item-total correlations ranged from 0.437 to 0.711, with the item "BPSD are the major source of caregiving burden" having the highest correlation (r=0.711). The results indicate that the BPSD-T is a reliable instrument for assessing caregivers' knowledge of behavioral and psychological symptoms associated with dementia.

CONCLUSION

The BPSD-T provides an effective means of identifying knowledge gaps among caregivers in Turkey and serves as a valuable tool for developing training programs aimed at improving the management of BPSD. This study contributes to the literature by validating the scale in a non-Western context, suggesting that enhancing caregivers' knowledge of BPSD can have positive impacts on clinical management and patient care. In this regard, the implementation of the BPSD-T may support the more effective management of behavioral and psychological symptoms in dementia patients.

Healthcare Professionals' Perspectives on Post-Diagnostic Care for People with Vascular Cognitive Impairment: When Help Is Needed in a "No-Man's Land"

Background

Post-diagnostic care for people with vascular cognitive impairment (VCI) typically involves multiple professions and disjointed care pathways not specifically designed to aid VCI needs.

Objective

Exploring perspectives of healthcare professionals on post-diagnostic care for people with VCI.

Methods

We conducted a qualitative focus group study. We used purposive sampling to include healthcare professionals in different compositions of primary and secondary care professionals per focus group. Thematic saturation was reached after seven focus groups. Transcripts were iteratively coded and analyzed using inductive thematic analysis.

Results

Forty participants were included in seven focus groups (4-8 participants). Results showed knowledge and awareness of VCI as prerequisites for adequate post-diagnostic care, and for pre-diagnostic detection of people with VCI (theme 1). In light of perceived lack of differentiation between cognitive disorders, participants shared specific advice regarding post-diagnostic care for people with VCI and informal caregivers (theme 2). Participants thought current care for VCI was fragmented and recommended further integration of care and collaboration across settings (theme 3).

Conclusions

People with VCI and their caregivers risk getting stuck in a "no man's land" between post-diagnostic care pathways; challenges lie in acknowledgement of VCI and associated symptoms, and alignment between healthcare professionals. Education about the symptoms and consequences of VCI, to healthcare professionals, people with VCI and caregivers, may increase awareness of VCI and thereby better target care. Specific attention for symptoms common in VCI could further tailor care and reduce caregiver burden. Integration could be enhanced by combining expertise of dementia and stroke/rehabilitation pathways.

Health Care Is Not Enough to Prevent Dementia

With an aging population, an increase in cases of Alzheimer's disease and dementia worldwide poses a significant health burden. While we hope for a cure, preventing dementia by reducing risks is important for global population health. Prevention strategies are difficult to implement when facing inequality across the world for access to healthy lifestyles. An approach that centers on individual responsibility and health professional interventions for targeted groups may risk missing the policy and environmental drivers of change. Barriers and enablers need to be explored and interventions are needed at individual, structural and social levels to normalize mid-life risk reduction.

Multidomain Dementia Risk Reduction in Primary Care is Feasible: A Proof-of-concept study

Background

Dementia risk reduction is a public health priority, but interventions that can be easily implemented in routine care are scarce.

Objective

To evaluate the feasibility of integrating dementia risk reduction in regular consultations in primary care and the added value of a dedicated smartphone app ('MyBraincoach').

Methods

188 participants (40-60 years), with modifiable dementia risk factors were included from ten Dutch general practices in a cluster-randomized trial (NL9773, 06/10/2021). Practices were randomly allocated (1 : 1) to provide a risk-reduction consultation only or to additionally provide the app. During the consultation, participants learned about dementia risk reduction and how to improve their risk profile. The app group received daily microteaching-notifications about their personally relevant risk factors. Feasibility was evaluated after 3 months using questionnaires assessing knowledge on dementia risk reduction and health behavior change. The primary outcome was change in the validated "LIfestyle for BRAin health" (LIBRA) score. In-depth interviews were conducted with participants and primary care providers (PCPs).

Results

The interventions were positively perceived, with 72.0% finding the consultation informative and 69.2% considering the app useful. Drop-out was low (6.9%). LIBRA improved similarly in both groups, as did Mediterranean diet adherence and body mass index. Knowledge of dementia risk reduction increased, but more in the app group. Interviews provided insight in participants' and PCPs' needs and wishes.

Conclusions

Integrating dementia risk reduction in primary care, supported by a smartphone app, is a viable approach towards dementia risk reduction. Larger trials are needed to establish (cost-)effectiveness.

Developing the Healthy Actions and Lifestyles to Avoid Dementia or Hispanos y el ALTo a la Demencia program

INTRODUCTION

With Alzheimer's disease and related dementias (ADRD) representing an enormous public health challenge, there is a need to support individuals in learning about and addressing their modifiable risk factors (e.g., diet, sleep, and physical activity) to prevent or delay dementia onset. However, there is limited availability for evidence-informed tools that deliver both quality education and support for positive behavior change such as by increasing self-efficacy and personalizing goal setting. Tools that address the needs of Latino/a, at higher risk for ADRD, are even more scarce.

METHODS

We established a multidisciplinary team to develop the Healthy Actions and Lifestyles to Avoid Dementia or Hispanos y el ALTo a la Demencia (HALT-AD) program, a bilingual online personalized platform to educate and motivate participants to modify their risk factors for dementia. Grounded in social cognitive theory and following a cultural adaptation framework with guidance from a community advisory board, we developed HALT-AD iteratively through several cycles of rapid prototype development, user-centered evaluation through pilot testing and community feedback, and refinement.

RESULTS

Using this iterative approach allowed for more than 100 improvements in the content, features, and design of HALT-AD to improve the program's usability and alignment with the interests and educational/behavior change support needs of its target audience. Illustrative examples of how pilot data and community feedback informed improvements are provided.

DISCUSSION

Developing HALT-AD iteratively required learning through trial and error and flexibility in workflows, contrary to traditional program development methods that rely on rigid, pre-set requirements. In addition to efficacy trials, studies are needed to identify mechanisms for effective behavior change, which might be culturally specific. Flexible and personalized educational offerings are likely to be important in modifying risk trajectories in ADRD.

Prevalence and Determinants of Diagnosed Dementia: A Registry Linkage Study Linking Diagnosis of Dementia in the Population-Based HUNT Study to Registry Diagnosis of Dementia in Primary Care and Hospitals in Norway

Background

A timely diagnosis of dementia can be beneficial for providing good support, treatment, and care, but the diagnostic rate remains unknown and is probably low.

Objective

To determine the dementia diagnostic rate and to describe factors associated with diagnosed dementia.

Methods

This registry linkage study linked information on research-based study diagnoses of all-cause dementia and subtypes of dementias, Alzheimer's disease, and related dementias, in 1,525 participants from a cross-sectional population-based study (HUNT4 70+) to dementia registry diagnoses in both primary-care and hospital registries. Factors associated with dementia were analyzed with multiple logistic regression.

Results

Among those with research-based dementia study diagnoses in HUNT4 70+, 35.6% had a dementia registry diagnosis in the health registries. The diagnostic rate in registry diagnoses was 19.8% among home-dwellers and 66.0% among nursing home residents. Of those with a study diagnosis of Alzheimer's disease, 35.8% (95% confidence interval (CI) 32.6-39.0) had a registry diagnosis; for those with a study diagnosis of vascular dementia, the rate was 25.8% (95% CI 19.2-33.3) and for Lewy body dementias and frontotemporal dementia, the diagnosis rate was 63.0% (95% CI 48.7-75.7) and 60.0% (95% CI 43.3-75.1), respectively. Factors associated with having a registry diagnosis included dementia in the family, not being in the youngest or oldest age group, higher education, more severe cognitive decline, and greater need for help with activities of daily living.

Conclusions

Undiagnosed dementia is common, as only one-third of those with dementia are diagnosed. Diagnoses appear to be made at a late stage of dementia.

Breaking the barriers: overcoming dementia-related stigma in minority communities

Dementia is a global health concern that affects individuals irrespective of their cultural or linguistic backgrounds. However, research has long recognized the pronounced stigma associated with dementia, particularly within Culturally and Linguistically Diverse (CALD) communities. This article seeks to summarize the underlying factors contributing to the heightened levels of dementia stigma within CALD communities, through a review of the literature. Our examination shows that cultural beliefs, language barriers, limited awareness, and the impact of migration on perceptions of aging and cognitive decline are contributing factors. Consequently, our analysis highlights the need for tailored, culturally appropriate interventions aimed at mitigating stigma and enhancing dementia care within CALD populations. Our proposed solutions, built on a social-ecological approach, highlights the critical role of collaborative efforts involving policymakers, healthcare providers, community organizations, and CALD community members in fostering a more dementia-inclusive society. This perspective piece aims to shed light on the distinct challenges faced by CALD communities, while advocating for a holistic approach to redefine perceptions and care strategies tailored to these populations.

Association between perceived risk of Alzheimer's disease and related dementias and cognitive function among U.S. older adults

INTRODUCTION

The aim of the study was to assess factors associated with the perceived risk of developing Alzheimer's disease and related dementias (ADRD) and how the perceived risk of ADRD was related to cognitive function.

METHODS

We conducted a retrospective cohort study using 5 waves of data from the Health and Retirement Study (2012-2022) that included adults aged 65 years or older with no previous diagnosis of ADRD at baseline. Cognitive function was measured at baseline and over time using a summary score that included immediate/delayed word recall, serial 7's test, objective naming test, backwards counting, recall of the current date, and naming the president/vice-president (range = 0-35). Perceived risk of developing ADRD was categorized at baseline as "definitely not" (0% probability), "unlikely" (1-49%), "uncertain" (50%), and "more than likely" (>50-100%). Additional baseline measures included participants' sociodemographic background, psychosocial resources, health behaviors, physiological status, and healthcare utilization.

RESULTS

Of 1457 respondents (median age 74 [IQR = 69-80] and 59.8% women), individuals who perceived that they were "more than likely" to develop ADRD had more depressive symptoms and were more likely to be hospitalized in the past two years than individuals who indicated that it was "unlikely" they would develop ADRD. Alternatively, respondnets who perceived that they would "definitely not" develop ADRD were more likely to be non-Hispanic Black, less educated, and have lower income than individuals who indicated it was "unlikely" they would develop ADRD. Respondents who reported their risks of developing ADRD as "more than likely" (β = -2.10, P < 0.001) and "definitely not" (β = -1.50, P < 0.001) had the lowest levels of cognitive function; and the associations were explained in part by their socioeconomic, psychosocial, and health status.

CONCLUSIONS

Perceived risk of developing ADRD is associated with cognitive function. The (dis)concordance between individuals' perceived risk of ADRD and their cognitive function has important implications for increasing public awareness and developing interventions to prevent ADRD.

To be or not to be: Arts-based approaches in public health messaging for dementia awareness and prevention

OBJECTIVES

Multiple modifiable risk factors exist across the lifespan to reduce dementia prevalence, and public understanding of these factors is increasing. Yet dementia is frequently misunderstood and stigmatised, and dementia prevention is not generally recognised as a health priority. Current limitations of public health campaigns for dementia prevention must be addressed and innovative alternatives developed to improve public comprehension and implementation of preventative action across all stages of life.

METHODS

In searching various databases and public information on dementia prevention, restraints were found in current health messaging which did not reflect the complexity of this health issue and address diversity of its impact across cultures and ages. In consultation with researchers and public health organisations, we outline four case studies in Australia where innovative arts-based approaches have been adopted and discuss the potential for arts-based approaches to address these gaps.

RESULTS

Arts-based approaches have the unique capacity to shift perceptions on ageing and dementia, overcome language and literacy barriers, represent health concerns across cultures, and actively involve individuals, communities and healthcare professionals in the process of dementia prevention. Future campaigns can engage a variety of communities and environments with art mediums suited to their preferences, capacities and efficacy.

CONCLUSIONS

Recommendations include example mediums, environments and people to engage. Future research is required to understand the impact of, and to improve, the long-term adoption of innovative arts-based approaches in dementia prevention practices.

Evaluating the General Population of Saudi Arabia for Their Knowledge, Attitudes, and Practices Towards Dementia

Introduction Dementia, a prevalent neurological condition, has a significant global impact on individuals and communities. Despite affecting approximately 50 million people worldwide, with an expected tripling by 2050, there are currently no widely available disease-modifying treatments. Recent efforts have concentrated on strategies involving legislation, regulations, and population-wide initiatives to address dementia risk, diagnosis, and care. Methods This cross-sectional survey engaged 6123 participants in Saudi Arabia, utilizing a multistage sampling design across provinces and cities. The study aimed to investigate the knowledge, attitudes, and practices of the Saudi Arabian general population regarding dementia. Results Participants displayed diverse opinions on dementia knowledge, with females exhibiting higher rates of knowledge, attitudes, and practices than males. Notably, 97.2% of females were aware of dementia compared to 78% of males. The perception of dementia as a healthcare priority was significantly higher in females (84.1%) than in males (59.6%). Older females (≥65) were identified as the age group most associated with dementia (92.50%) compared to males (71.10%). Conclusion While participants demonstrated excellent knowledge of hearing about dementia, understanding symptoms, and identifying modifiable factors, their knowledge regarding prevention and curability was found to be inadequate. A significant gender association was observed, with females exhibiting higher knowledge, attitudes, and practices than males.

Older adults' awareness of modifiable risk and protective factors for dementia and interest in eHealth interventions for brain health: a comparison between the Netherlands and Germany

BACKGROUND

Evidence on modifiable risk factors for dementia is accumulating rapidly, including e.g. smoking, hypertension, and diabetes. Comparing knowledge of risk factors for dementia and factors associated with knowledge and motivation to learn about dementia risk reduction in different countries may support the design of tailored public health campaigns. We investigated (1) differences in knowledge of risk and protective factors for dementia between the Netherlands and Germany, and interest in (2) information on brain health and (3) eHealth for brain health.

MATERIALS AND METHODS

Population-based telephone (Germany) or web-based surveys (Netherlands) were conducted among adults aged 60-75 (ntotal=614; Germany: n = 270; Netherlands: n = 344), assessing sociodemographic factors, knowledge of risk and protective factors for dementia, interest in information on brain health and respective eHealth-tools. Correlates of knowledge, interest in information on brain health and eHealth for brain health were analyzed using multivariable regression, by country and in pooled analyses.

RESULTS

In the total sample (Mage: 67.3 (SD: 4.3) years; %female: 48.6), knowledge of risk and protective factors (sum score assessing number of correctly identified factors) was higher among German participants (M (SD) = 7.6 (2.5) vs. 6.0 (4.3), p < .001). This was confirmed using linear regression analyses, controlling for sociodemographic covariates (b = 1.51; 95% CI: 1.00; 2.01). High education was linked to better knowledge of risk and protective factors (b = 1.61; 95% CI: 0.89; 2.34). Controlling for covariates, interest in information on brain health (OR: 0.05, 95% CI: 0.02; 0.09) and eHealth for brain health (OR: 0.40, 95% CI: 0.25; 0.65) was lower in German participants. Widowed participants were less interested in information on brain health, while widowed and single participants expressed less interest in eHealth for brain health in pooled analyses. Further associations between sociodemographic factors, interest in information on brain health and eHealth for brain health by country were detected.

DISCUSSION

Engaging older adults in the design of eHealth interventions and cooperation with trusted sources, e.g., general practitioners, might enhance appreciation of eHealth for brain health. Education on risk and protective factors for dementia is warranted in both countries. However, differences in recruitment and assessment need to be acknowledged.

A Systematic Review of Quality Dementia Clinical Guidelines for the Development of WHO's Package of Interventions for Rehabilitation

BACKGROUND AND OBJECTIVES

As part of the WHO Rehabilitation 2030 call for action, the WHO Rehabilitation Programme is developing its Package of Interventions for Rehabilitation (PIR) to support ministries of health around the globe in integrating rehabilitation services into health systems. As a vital step for this PIR development, we conducted a systematic review of clinical practice guidelines (CPGs) for dementia to identify interventions for rehabilitation and related evidence.

RESEARCH DESIGN AND METHODS

Following WHO Rehabilitation Programme and Cochrane Rehabilitation's methodology, quality CPGs published in English between January 2010 and March 2020 were identified using PubMed, Embase, CINAHL, PEDro, Google Scholar, guideline databases, and professional society websites. Guideline quality was assessed using the Appraisal of Guidelines for Research and Evaluation (II).

RESULTS

Of the 22 CPGs that met the selection criteria, 6 satisfied the quality evaluation. Three hundred and thirty rehabilitation-related recommendations were identified, mostly concentrated in the areas of cognition, emotion, and carer support. There were many strong interventions, with moderate- to high-quality evidence that could be easily introduced in routine practice. However, major limitations were found both in the quality of evidence and scope, especially in areas such as education and vocation, community and social life, and lifestyle modifications.

DISCUSSION AND IMPLICATIONS

Further rigorous research is needed to build quality evidence in dementia rehabilitation in general, and especially in neglected areas for rehabilitation. Future work should also focus on the development of CPGs for dementia rehabilitation. A multipronged approach is needed to achieve Universal Health Coverage for dementia rehabilitation.

Education as a Moderator of Help Seeking Behavior in Subjective Cognitive Decline

OBJECTIVE

Disparities in Alzheimer disease (AD) and differences in help seeking (HS) across sociodemographic groups warrant public health concern. Research addressing such disparities must shift toward the earliest clinical manifestations of AD to optimize diagnosis, intervention and care planning. Subjective cognitive decline (SCD), a risk state for AD, provides an important context in which to examine sociodemographic-related disparities in HS.

PARTICIPANTS AND METHODS

One hundred sixty-seven cognitively healthy older adults (M age =73, M education =16) (26.4% Black, Asian, or "Other") completed SCD questionnaire, HS questions, and mood measures (depression and anxiety). Binary logistic adjusted regressions examined: (a) the association between SCD and HS; and (b) the extent to which education moderated the relationship between SCD and HS. SCD [b = 0.06, SE=0.13, P <0.001, odds ratio=1.06, 95% CI (1.03, 1.08)] and education [b=0.32, SE=0.09, P <0.001, odds ratio=1.37, 95% CI (1.15, 1.64)] were independently associated with HS, with significant interaction between education and SCD on HS [b=0.2, SE=0.01, P =0.01, odds ratio=1.02, 95% CI (1.00, 1.03)].

CONCLUSIONS

Findings elucidate the importance of tailoring SCD-related psychoeducational resources depending on educational background as a preliminary stepping-stone in encouraging HS among older adults who may be at particular risk for developing dementia.

Who is Responsible? Attribution of Responsibility in the Context of Dementia: A Content-Analysis of Framing in Media Coverage

Dementia is currently one of the most significant public health challenges from a medical as well as a societal perspective. The number of people living with dementia is increasing, and there is conflicting evidence in terms of preventive measures and risk factors. The available therapies can slow down but neither stop nor reverse the condition. Educating the public about these circumstances is thus of utmost relevance. As the mass media are a major source of health-related information, this study uses a quantitative content analysis to examine the extent to which responsibility framing occurs concerning risk and protection factors for dementia. Besides the established levels of individual and society, this study considers the level "social network" as an independent level to account for the supporting role of relatives and friends in the care of people living with dementia. The results show that protection factors for dementia are reported more frequently than the risk factors of the condition. Further, attribution of responsibility for risk factors tended to be at the individual level, while protection was the responsibility of society and the social network.

[What does the population know about risk and protective factors for dementia? An international review of the current state of knowledge in various countries]

BACKGROUND

The scientific state of knowledge on modifiable risk factors for dementia has greatly improved in recent years. The established risk and protective factors include physical and social inactivity, hypertension, diabetes mellitus, excessive alcohol consumption and smoking; however, it is assumed that this knowledge is so far insufficiently disseminated among the general population, indicating untapped potential for primary prevention of dementia.

OBJECTIVE

To assess the state of knowledge on established risk and protective factors for dementia in the general population.

MATERIAL AND METHODS

Based on a systematic literature search in the PubMed database, international studies that investigated the knowledge on modifiable risk and/or protective factors for dementia in samples from the general population were identified.

RESULTS AND CONCLUSION

A total of 21 publications were included in the review. The majority of publications (n = 17) collated risk and protective factors using closed questions, while n = 4 studies used open questions. Lifestyle factors, e.g. cognitive, social and physical activity, were most frequently named as protective against dementia. Furthermore, many participants recognized depression as a risk factor for dementia. Knowledge of cardiovascular risk constellations for dementia, such as hypertension, hypercholesterolemia or diabetes mellitus were much less known among the participants. The results indicate that there is a need for a targeted clarification of the role of pre-existing cardiovascular diseases as risk factors for dementia. Studies assessing the state of knowledge on social and environmental risk and protective factors for dementia are currently scarce.

Alzheimer's disease (AD) knowledge in Korean Americans: identifying knowledge gaps and misconceptions and examining predictors of AD knowledge

OBJECTIVES

This study examined Alzheimer's disease (AD) knowledge and its predictors among Korean Americans (KAs).

DESIGN

Convenience sampling was used to recruit KAs in the Greater Washington metropolitan area. A total of 268 KAs participated in the study and completed a cross-sectional survey in 2014. Using the Alzheimer's Disease Knowledge Scale (ADKS), overall and domain knowledge was assessed. Multiple regression analyses were conducted for overall and domain knowledge with predictors including exposure to AD, social engagement, sources and frequency of health-related information, stigmatic beliefs (pity, antipathy, and social distance), English proficiency, and education.

RESULTS

KAs reported a 59% accuracy in the overall AD knowledge. At the domain level, KAs were most knowledgeable about assessment and diagnosis and least knowledgeable about caregiving. Our regression analyses showed that having a college degree or higher is associated with a greater overall AD knowledge. Three domain models of life impact, risk factors, and caregiving turned out to be significant: Having a college degree or higher is a predictor of greater knowledge in all three domains. Having more pity stigmatic beliefs is related to greater knowledge in both life impact and caregiving domains while having less pity stigmatic beliefs is associated with more risk factor knowledge; having less social distance stigmatic beliefs is associated with greater life impact knowledge; and having less antipathy stigmatic beliefs is related to better caregiving knowledge.

CONCLUSION

Our findings revealed areas of misconceptions and knowledge gaps in KAs which need to be addressed in educational interventions. Different knowledge status across the domains demonstrates a multi-dimensional nature of AD knowledge. Multivariate findings confirmed the robust role of education in overall and domain AD knowledge. The effect of different AD stigmatic beliefs on certain AD knowledge domains suggests ways of how stigma change can be efficient for the purpose of increasing AD domain knowledge in KAs.

[Brain health services: individual dementia risk profiling at the Cologne Alzheimer Prevention Center]

BACKGROUND

According to current knowledge approximately 30-40% of all cases of dementia can be attributed to modifiable risk factors. As a result, dementia prevention and the concept of brain health are becoming increasingly relevant.

RESEARCH QUESTION

The requirements for brain health services and their implementation are discussed and the Cologne Alzheimer Prevention Center (KAP) of the University Hospital Cologne is described as an example.

MATERIAL AND METHODS

In addition to a report on international brain health initiatives, the main activities of the KAP are presented. A program for individual risk profiling and risk communication is provided, which was piloted in the KAP in the context of the "Individual risk profiling for Alzheimer's disease and dementia prevention (INSPIRATION)" study. The prevalence of risk factors in a cognitively healthy sample aged 50-86 years (n = 162) with interest in dementia prevention is presented.

RESULTS

The most common risk factors were non-Mediterranean diet, obesity, subjective poor sleep quality and increased stress. Based on these results, preventive interventions can be developed that are adapted to the individual risk profile as a personalized medicine approach.

DISCUSSION

Structures such as the KAP can provide individual risk factor assessment and personalized dementia prevention. The efficacy of this approach on dementia risk reduction needs to be evaluated.

Knowledge, Awareness, and Attitude of Healthcare Stakeholders on Alzheimer's Disease and Dementia in Qatar

Dementia is characterized by progressive cognitive decline, memory impairment, and disability. Alzheimer's disease (AD) accounts for 60-70% of cases, followed by vascular and mixed dementia. Qatar and the Middle East are at increased risk owing to aging populations and high prevalence of vascular risk factors. Appropriate levels of knowledge, attitudes, and awareness amongst health care professionals (HCPs) are the need of the hour, but literature indicates that these proficiencies may be inadequate, outdated, or markedly heterogenous. In addition to a review of published quantitative surveys investigating similar questions in the Middle East, a pilot cross-sectional online needs-assessment survey was undertaken to gauge these parameters of dementia and AD among healthcare stakeholders in Qatar between 19 April and 16 May 2022. Overall, 229 responses were recorded between physicians (21%), nurses (21%), and medical students (25%), with two-thirds from Qatar. Over half the respondents reported that >10% of their patients were elderly (>60 years). Over 25% reported having contact with >50 patients with dementia or neurodegenerative disease annually. Over 70% had not undertake related education/training in the last 2 years. The knowledge of HCPs regarding dementia and AD was moderate (mean score of 5.3 ± 1.5 out of 7) and their awareness of recent advances in basic disease pathophysiology was lacking. Differences existed across professions and location of respondents. Our findings lay the groundwork for a call-to-action for healthcare institutions to improve dementia care within Qatar and the Middle East region.

Perceptions of community members in Australia about the risk factors, symptoms and impacts of dementia: A cross-sectional questionnaire study

OBJECTIVES

Ensuring that the Australian public has an accurate understanding of the characteristics of dementia may assist in improving timely detection of dementia. This cross-sectional questionnaire study aimed to examine community members' perceptions of the risk factors, symptoms and impacts of dementia.

METHODS

Participants were recruited from outpatient units at a major regional hospital and were aged at least 18 years, a patient or an accompanying support person, did not have a dementia diagnosis, had sufficient English knowledge and were well enough to complete a survey. Participants completed a web-based survey on a touchscreen computer including items exploring knowledge of dementia risk factors, symptoms and perceived impacts if they or a loved one had dementia. Counts and proportions were calculated and perceived impacts of dementia were compared for self versus loved one using a χ2 test.

RESULTS

Of 353 eligible individuals approached, 208 consented and were included in the study. Between 30% and 61% (n = 62-127) of participants believed modifiable factors such as high alcohol consumption and high blood pressure were associated with increased risk of dementia. While a majority of participants (87-96%; n = 164-181) identified memory-related symptoms, less than one-third recognised behavioural symptoms. Participants were more likely to identify emotional and practical impacts compared to physical or social impacts as most difficult if they or a loved one had dementia.

CONCLUSIONS

There remains a need for increased community education to address knowledge gaps regarding modifiable risk factors, behavioural symptoms and potential impacts of dementia on the individual diagnosed and their carers.

Factors Associated with Participation in a Multidomain Web-Based Dementia Prevention Trial: Evidence from Maintain Your Brain (MYB)

BACKGROUND

The Maintain Your Brain (MYB) trial aims to prevent cognitive decline and dementia through multidomain, web-based risk-reduction. To facilitate translation, it is important to understand drivers of participation.

OBJECTIVE

To describe characteristics associated with participation in MYB.

METHODS

This was an observational ancillary study of MYB, a randomized controlled trial nested within the 45 and Up Study in New South Wales, Australia. We linked 45 and Up Study survey and MYB participation data. The study cohort comprised 45 and Up Study participants, aged 55-77 years at 1 January 2018, who were invited to participate in MYB. 45 and Up Study participant characteristics and subsequent MYB consent and participation were examined.

RESULTS

Of 98,836 invited, 13,882 (14%) consented to participate and 6,190 participated (6%). Adjusting for age and sex, a wide range of factors were related to participation. Higher educational attainment had the strongest relationship with increased MYB participation (university versus school non-completion; AdjOR = 5.15; 95% CI:4.70-5.64) and lower self-rated quality of life with reduced participation (Poor versus Excellent: AdjOR = 0.19; 95% CI:0.11-0.32). A family history of Alzheimer's disease was related to increased participation but most other dementia risk factors such as diabetes, obesity, stroke, high blood pressure, and current smoking were associated with reduced participation.

CONCLUSION

Higher socio-economic status, particularly educational attainment, is strongly associated with engagement in online dementia prevention research. Increasing population awareness of dementia risk factors, and better understanding the participation barriers in at-risk groups, is necessary to ensure online interventions are optimally designed to promote maximum participation.

Modifiable risk factors for dementia, and awareness of brain health behaviors: Results from the Five Lives Brain Health Ireland Survey (FLBHIS)

Up to 40% of dementias globally are attributable to modifiable risk factors. Many existing studies examining attitudes to brain health are limited by a failure to consider a range of pertinent risk factors and associated barriers to protective behaviors. In Ireland, self-reported knowledge of dementia is poor compared to other conditions. In this context, the current study aimed to explore exposure to and awareness of specific modifiable risk factors for dementia. We also aimed to investigate whether exposure to these risk factors is associated with demographic and socioeconomic factors. A cross-sectional survey was administered to 555 voluntary participants in February 2022. The survey captured the following information: (1) Sociodemographic factors; (2) Exposure to, as well as knowledge of modifiable risk factors for dementia, namely diet, social interaction, exercise, hypertension, sleep, depression, smoking, alcohol consumption, cognitive stimulation, hearing impairment, diabetes, air pollution, and head injury. The study population comprised 551 participants (50.3% male; 49.6% female). Mean age was 59.7 years. Modifiable risk factors for dementia were prevalent. Relative to females, male gender was significantly associated with multiple risk factors. Whilst 65.6% of participants believed that lifestyle improvements can decrease a person's risk of developing dementia, only 31.4% believed that dementia could be prevented. Head injury (90.9%, n = 500), low mental stimulation (85.3%, n = 469), and alcohol consumption (77.8%, n = 428) were the three most commonly recognized risk factors. Awareness was significantly greater in both university groups (undergraduate and postgraduate) for multiple risk factors. Our findings demonstrate that the distribution of exposure to modifiable risk factors for dementia is unequal across gender and age groups, and that awareness levels vary across risk factors. These findings highlight that focus surrounding dementia prevention should shift toward individual risk profiling and should be tailored toward an individual's specific needs.

Costs of Dementia in Low- And Middle-Income Countries: A Systematic Review

BACKGROUND

The proportion of people living with dementia in low- and middle-income countries (LMICs) is expected to reach 71% by 2050. Appraising the economic burden of the disease may contribute to strategic policy planning.

OBJECTIVE

To review studies conducted on the costs of dementia in LMICs, describe their methodology and summarize available costs estimates.

METHODS

Systematic review, including a search of health, economics, and social science bibliographic databases. No date or language restrictions were applied. All studies with a direct measure of the costs of dementia care were included.

RESULTS

Of the 6,843 publications reviewed, 17 studies from 11 LMICs were included. Costs of dementia tended to increase with the severity of the disease. Medical costs were greater in the mild stage, while social and informal care costs were highest in the moderate and severe stages. Annual cost estimates per patient ranged from PPP$131.0 to PPP$31,188.8 for medical costs; from PPP$16.1 to PPP$10,581.7 for social care services and from PPP$140.0 to PPP$25,798 for informal care. Overall, dementia care can cost from PPP$479.0 to PPP$66,143.6 per year for a single patient.

CONCLUSION

Few studies have been conducted on the costs of dementia in LMICs, and none so far in Africa. There seems to be a need to provide accurate data on the burden of disease in these countries to guide public health policies in the coming decades.

Short report: A trend analysis of attitudes towards early diagnosis of dementia in Germany

BACKGROUND

Early detection of dementia provides numerous benefits for those living with dementia and their relatives and healthcare systems at large. Methods available for early diagnosis have improved significantly over the past years. Therefore, we examined whether support for offering an early diagnosis of dementia and willingness to pursue a respective early diagnosis have changed in Germany over the last decade.

METHOD

We compared findings from two representative telephone surveys conducted among older adults in Germany (≥ 60 years of age) in 2011 and 2022, assessing support for offering an early diagnosis of dementia and willingness to pursue a respective early diagnosis in a sample of n = 879 individuals (mean age: 72.9, range: 60-98 years, % female: 58.8). Group comparisons using Chi2- and t-tests and multivariable regression analyses were conducted, regressing support of an early diagnosis of dementia and willingness to pursue a respective early diagnosis on age, gender, education, employment status, belief in preventability of dementia and time of survey.

RESULTS

Support for offering an early diagnosis of dementia was high both in 2011 (90.7%) and 2022 (79.2%), but declined over time (OR: .39; 95% CI: .25; .63). Willingness to pursue an early diagnosis of dementia declined from 70.7% to 60.1% in the same period (OR: .62; 95% CI: .45; .86). Belief in preventability of dementia was linked to support for offering an early diagnosis (OR: 1.88, 95% CI: 1.25; 2.83) and willingness to pursue an early diagnosis of dementia (OR: 1.52; 95% CI: 1.12; 2.07). Older participants less often supported offering an early diagnosis of dementia (OR: .97, 95% CI: .95; .99).

CONCLUSION

Support for offering an early diagnosis of dementia and willingness to pursue a respective diagnosis is high in the older German public, but lower than reported previously. Improving knowledge on modifiable risk factors and better understanding of individual motives underlying endorsement or refusal of an early diagnosis may increase acceptance in the general public.

Jordanian Community People's Knowledge of and Attitudes Toward Dementia

Introduction

Limited research exists on the knowledge and attitudes of Jordanian community residents toward people with dementia (PwD). As the prevalence of dementia is anticipated to increase, there is a critical need for informed knowledge and positive attitudes toward dementia in the Jordanian community.

Objectives

This study aimed to evaluate people's knowledge of and attitudes toward PwD and identify the predictors of dementia knowledge and attitudes.

Methods

The study employed a cross-sectional research design and utilized a self-administered questionnaire as the primary data collection method. The study employed the Alzheimer's Disease Knowledge Scale (ADKS) to evaluate the knowledge of the participants, and the Dementia Attitudes Scale (DAS) was utilized to assess their attitudes in the Jordanian community. Multiple regression analysis was performed to find relevant factors influencing knowledge of and attitude toward dementia.

Results

The study's 346 participants revealed limited knowledge about dementia, with an average ADKS score of 17.21 out of 30. However, participants showed a positive attitude toward dementia, as evidenced by a mean DAS score of 88 out of 140. Statistical analysis demonstrated significantly higher knowledge scores among employed individuals (P < .05), while females exhibited significantly higher attitude scores (P < .05). Participants with experience in geriatric clinical practice, dementia education or training, informal caregiving experience, and a desire to learn more about dementia also exhibited significantly higher knowledge and attitude scores (P < .05).

Conclusion

The study offers preliminary insights into the knowledge and attitudes toward dementia in the Jordanian population. The findings underscore the importance of continuing education and training to increase knowledge and understanding of dementia. Improving dementia care and support in Jordan requires enhancing knowledge and attitudes toward dementia. The study findings were presented to policymakers, with recommendations for strategic planning and the development of awareness programs. Future research can build upon these findings and promote evidence-based practices in dementia care and community awareness programs.

Public Perspectives on Lifestyle-Related Behavior Change for Dementia Risk Reduction: An Exploratory Qualitative Study in The Netherlands

BACKGROUND

There is accumulating evidence that addressing modifiable risk and protective factors has an impact on dementia rates. Insight into the public's perspectives on dementia risk reduction is needed to inform future individual-level interventions and public health approaches.

OBJECTIVE

This study explores the publics' openness towards dementia risk reduction and willingness towards changing lifestyle behavior to reduce the future risk for dementia.

METHODS

Using a screening questionnaire, participants were purposively selected based on lifestyle behaviors that are associated with dementia risk. One-on-one interviews were used to explore their openness towards dementia risk reduction and willingness towards behavior change. Independently, two researchers performed an inductive content analysis.

RESULTS

Interviews were conducted with 23 participants aged from 40 to 79 years. Main themes that were identified from the data were: 1) abstractness of dementia risk reduction, 2) ambivalence towards changing behavior, 3) negative self-image and low behavioral control, and 4) all-or-nothing thinking about lifestyle change.

CONCLUSIONS

The concept of dementia risk reduction seems difficult to translate to the personal context, particularly if individuals perceive that dementia would occur decades in the future. This is problematic because a large proportion of the public needs a healthier lifestyle to reduce the incidence of dementia. Translating healthy intentions into behavior is complex and involves overcoming a variety of barriers that complicate dementia risk reduction initiatives. Support is needed for individuals who experience additional obstacles that obstruct commencing to a healthier lifestyle (e.g., negative self-image, engaging in multiple unhealthy behaviors, unrealistic perceptions about lifestyle change).

Using mHealth for Primary Prevention of Dementia: A Proof-of-Concept Study on Usage Patterns, Appreciation, and Beliefs and Attitudes Regarding Prevention

BACKGROUND

Health- and lifestyle factors account for a substantial part of all dementia cases, which opens the opportunity for primary prevention. However, the required behavioral change is complex and involves targeting multiple risk factors. mHealth interventions can potentially contribute to improving motivation in a low-cost and scalable way.

OBJECTIVE

To explore usage patterns, appreciation, and beliefs and attitudes regarding dementia risk reduction during the use of the MyBraincoach mobile app.

METHODS

Participants were community-dwelling middle-aged adults from the Netherlands and used either the standard (education) or extended (education+motivational triggers) app version for three months. Two panel studies were combined in this paper. Chi-square tests, t-tests and linear mixed models were used, adjusted for age, sex, and education.

RESULTS

Of all participants (n = 299, 50.2% male), 167 (55.9%) had installed the app. The most reported reason for non-use was technical problems (47%). Those who used the app were at baseline already more positive about dementia risk reduction than those who did not use the app. Of all users who completed the evaluation (n = 102), 78.4% (n = 80) stated that the app provided a positive approach towards brain health and 80.4% (n = 82) felt better informed. Younger (<60y) and lower educated participants evaluated the app most positively.

CONCLUSION

Usage of the app was low, but users showed more positive beliefs and attitudes regarding dementia risk reduction. Most users evaluated the app positively and stated to have gained knowledge on the topic. Improving the use of the app must keep high priority in future studies.
