Knowledge, Attitudes, and Stigma Related to Dementia Among Illiterate and Literate Older Adults in Shanghai

Illiterate Addenbrooke's Cognitive Examination-III in Three Indian Languages: An Adaptation and Validation Study

BACKGROUND

Literacy is an important factor that predicts cognitive performance. Existing cognitive screening tools are validated only in educated populations and are not appropriate for older adults with little or no education leading to poor performance on these tests and eventually leading to misdiagnosis. This challenge for clinicians necessitates a screening tool suitable for illiterate or low-literate older individuals.

OBJECTIVES

The objective was to adapt and validate Addenbrooke's Cognitive Examination-III (ACE-III) for screening general cognitive functions in illiterate and low-literate older populations in the Indian context in three languages.

METHOD

The Indian illiterate ACE-III was systematically adapted by modifying the original items of the Indian literate ACE-III to assess the cognitive functions of illiterates and low-literates with the consensus of an expert panel of professionals working in the area of dementia and related disorders. A total of 180 illiterate or low-literate participants (84 healthy-controls, 50 with dementia, and 46 with mild cognitive impairment [MCI]) were recruited from three different centers speaking Bengali, Hindi, and Kannada to validate the adapted version.

RESULTS

The optimal cut-off score for illiterate ACE-III to distinguish controls from dementia in all 3 languages was 75. The optimal cut-off scores in distinguishing between controls and MCI ranged from 79 to 82, with a sensitivity ranging from 93% to 99% and a specificity ranging from 72% to 99%.

CONCLUSION

The test is found to have good psychometric properties and is a reliable cognitive screening tool for identifying dementia and MCI in older adults with low educational backgrounds in the Indian context.

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.

Knowledge and Attitudes Regarding Geriatric Depression: A Descriptive Study Among Adult Saudi Citizens

BACKGROUND

Depression is a leading cause of disability and contributes significantly to the overall burden of any disease. In Saudi Arabia, the geriatric population over 65 is continuing to expand and will contribute to a significant portion of the Saudi community. As the population of the elderly continues to grow as a result of longer lifespans, there will be an increase in the number of individuals in this population suffering from undiagnosed geriatric depression.

AIM OF THE WORK

This study aims to assess the general population's attitude and knowledge about the symptoms, signs, and complications of geriatric depression to improve the quality of life of the elderly.

METHOD

This is a cross-sectional study, using a convenience sample of 2,320 participants, between March to September 2022. However, due to age, nationality, and incomplete responses that did not meet our inclusion criteria, 629 participants were excluded, and the sample size narrowed to 1,691. A structured questionnaire was designed to collect data based on a comprehensive literature review. An online survey was distributed to Saudi citizens. The participants were between 18 and 50, both women and men and only Saudi nationals were included. This age group was selected as a convenient, purposeful sample, assuming that this portion of the population will be able to be enrolled in an electronic survey in addition to their direct contact with elderlies as possible caregivers. All analyses were performed using IBM SPSS Statistics software for Windows, version 26.0 (IBM Corp., Armonk, NY). The data were analyzed using a nonparametric test because they were not normally distributed.

RESULTS

The study comprised 1,691 participants from diverse regions of Saudi Arabia, with a significant gender disparity observed, including 1,249 females (73.9%) and 442 males (26.1%). The majority of our participants were between 18-29 years, accounting for 55.2% of the sample. Descriptive statistics revealed prevalent beliefs among participants regarding geriatric depression. Notably, 35.1% strongly agreed and 19.3% agreed that depression affects individuals of particular ages, while a significant portion (47.1%) disagreed with the statement that depression in the elderly is a health problem. Additionally, 33.9% disagreed that geriatric depression can lead to suicide, and 33.8% believed it can be prevented. Analysis of actions and behaviors highlighted avoidance tendencies, with only 1.5% of the population strongly agreeing to treat a family member with geriatric depression and a majority (63.7%) avoiding interaction due to fear of harm, including 29.5% who strongly agreed and 34.2% who agreed. Gender differences were evident in emotional responses and knowledge levels, with females exhibiting higher emotional responses (mean score 15.63±2.92) and males displaying greater knowledge (mean score 14.90±3.36).

CONCLUSION

In this study, we investigated the knowledge and attitudes of Saudis toward depression in the elderly. Findings revealed an inadequate understanding of geriatric depression, with many not recognizing it as a health condition and underestimating its severity. Negative emotions and behaviors, such as shame and reluctance to provide support, were prevalent. Gender, education level, and region influenced attitudes and knowledge. These results underscore the need for targeted interventions to raise awareness and challenge the stigma surrounding geriatric depression in Saudi Arabia.

Altered limbic functional connectivity in individuals with subjective cognitive decline: Converging and diverging findings across Chinese and German cohorts

INTRODUCTION

It remains unclear whether functional brain networks are consistently altered in individuals with subjective cognitive decline (SCD) of diverse ethnic and cultural backgrounds and whether the network alterations are associated with an amyloid burden.

METHODS

Cross-sectional resting-state functional magnetic resonance imaging connectivity (FC) and amyloid-positron emission tomography (PET) data from the Chinese Sino Longitudinal Study on Cognitive Decline and German DZNE Longitudinal Cognitive Impairment and Dementia cohorts were analyzed.

RESULTS

Limbic FC, particularly hippocampal connectivity with right insula, was consistently higher in SCD than in controls, and correlated with SCD-plus features. Smaller SCD subcohorts with PET showed inconsistent amyloid positivity rates and FC-amyloid associations across cohorts.

DISCUSSION

Our results suggest an early adaptation of the limbic network in SCD, which may reflect increased awareness of cognitive decline, irrespective of amyloid pathology. Different amyloid positivity rates may indicate a heterogeneous underlying etiology in Eastern and Western SCD cohorts when applying current research criteria. Future studies should identify culture-specific features to enrich preclinical Alzheimer's disease in non-Western populations.

HIGHLIGHTS

Common limbic hyperconnectivity across Chinese and German subjective cognitive decline (SCD) cohorts was observed. Limbic hyperconnectivity may reflect awareness of cognition, irrespective of amyloid load. Further cross-cultural harmonization of SCD regarding Alzheimer's disease pathology is required.

New Community and Sociohealth Challenges Arising from the Early Diagnosis of Mild Cognitive Impairment (MCI)

Population aging increases the risk of developing neurodegenerative diseases that cause cognitive impairment. Advances in clinical practice and greater social awareness of the importance of cognitive impairment have led to an increase in the number of people with early diagnosis, predementia. Increasing access to biomarkers to assess whether Alzheimer's disease (AD) is the underlying cause of mild cognitive impairment (MCI) has undoubted clinical benefits (access to potentially disease-modifying treatments, among others) but is also responsible for new social-health care challenges. Understanding the psychosocial impact of a diagnosis of MCI due to AD or another neurodegenerative disease is essential to create future strategies to reduce the emotional overload of patients, their risk of discrimination and stigmatization, and to favor their social inclusion. We present a narrative review of the diagnostic process of mild cognitive impairment in clinical practice, with a holistic person-centered approach, and discuss the implications of such diagnosis (benefits and risks) and strategies on how to address them.

Knowledge and Attitudes towards Dementia among the General Public in Singapore: A Comparative Analysis

INTRODUCTION

This paper provides a summary of findings on the public's knowledge and attitudes towards dementia. We aim to investigate if the attitudes of Singaporeans towards dementia have changed over the years by adopting a questionnaire used in a similar study in 2012.

METHODS

A cross-sectional, descriptive study was conducted through the dissemination of an existing, online questionnaire to participants above 16 years of age. Out of 1,500 subjects, results from 1,373 participants were analysed. Descriptive statistics were used to analyse and compare results from the 2012 study while a latent class analysis was performed to understand the categories of study participants based on varying levels of attitudes, knowledge and stigma.

RESULTS

The mean age of study participants was 43.8 (SD = 15.7). Majority of the participants were females (76.5%), between 51 and 60 years of age (29.6%) and belonged to the Chinese ethnic group (77.8%). Results demonstrated that there were significant differences in attitudes towards dementia between 2012 and 2021. There was a 70.2% improvement in stigma-associated attitudes and an increase in correct responses to 4 out of 5 questions in the knowledge section.

CONCLUSION

Findings of this study suggest that the general public has a better knowledge and more positive attitude towards dementia. This could have been attributed to higher literacy levels of the current study population and effectiveness of established outreach initiatives in Singapore. However, further research with a more balanced representation of ethnic and cultural groups would offer more comprehensive insights into dementia health literacy.

Living with dementia: Why I am thinking of 'death'

BACKGROUND AND AIMS

Dementia is recognized globally as a massive burden on public health and wider society. It is a major cause of disability and mortality amongst older people. China has the largest population of people with dementia worldwide, accounting for approximately 25% of the entire global population of people with dementia. The study investigated the perceived experiences of care giving and care receiving in China, with one area identified in the data concerning the extent to which the participants discussed death. The research also explored the meaning of living with dementia in modern China, where the economy, demography and culture are rapidly changing.

METHOD

The qualitative approach of interpretative phenomenological analysis was used for this study. Semi-structured interviews were used for data collection.

FINDING

The paper reports on one specific finding concerning death as a way out of the situation that participants found themselves in.

CONCLUSION

The study described and interpreted one of the specific issues, 'death', in the participants' narratives. This finding reflects how psychological and social factors, such as stress, social support, healthcare cost, caring burden and medical practice have created the participants' thoughts of 'wishing to die' and the reasons why they believe 'death is a way to reduce burden'. It calls for an understanding, supportive social environment and a reconsideration of a culturally and economically appropriate family-based care system.

Attitudes, Motivations, and Barriers to Pre-Symptomatic Alzheimer's Disease Screening: Development and Validation of the 'Perceptions regarding pRE-symptomatic Alzheimer's Disease Screening' (PRE-ADS) Questionnaire

BACKGROUND

Pre-symptomatic screening methods for detecting a higher risk of Alzheimer's disease (AD) are gaining popularity; thus, more people are seeking these tests. However, to date, not much is known about the attitudes toward pre-symptomatic AD screening.

OBJECTIVE

The goal of this study is to examine the psychometric properties of a tool for assessing the attitudes, barriers, and motivations to pre-symptomatic AD screening.

METHODS

This is a cross-sectional study performed on 208 Greek participants (189 students and 19 caregivers) provided with an online questionnaire. Psychometric properties were assessed through the examination of its construct validity (principal component analysis) and internal consistency.

RESULTS

Exploratory factor analysis revealed the presence of four factors. The first factor is labeled as "Perceived harms of testing" (10 items), the second "Acceptance of testing" (5 items), the third "Perceived benefits of testing" (6 items), and the fourth factor "Need for knowledge" (4 items). The reliability (internal consistency) of each factor separately was acceptable to good (0.70-0.87) while the internal consistency of the overall questionnaire (25 items) was good (Cronbach's α=0.82).

CONCLUSION

PRE-ADS is a valid questionnaire that might help in the research of peoples' attitudes related to the pros and cons of pre-symptomatic screening for AD, and the development of effective counseling programs and prevention strategies. However, future research is required in the target population.

Attitudes towards dementia among Chinese adults aged 50 years and older: a comparative study of immigrants living in Melbourne and nonimmigrants living in Beijing

OBJECTIVES

This study investigated attitudes towards dementia among Chinese immigrants aged 50 years and over living in Australia and compares these attitudes with those of individuals living in mainland China. It aimed to better understand what older Chinese adults think about dementia and to inform the development of tailored dementia-related services for this group of people.

DESIGN

A qualitative design involving individual interviews was employed in this study.

PARTICIPANTS

Forty-six participants were recruited: 21 in Melbourne and 25 in Beijing. All interviewees were born in mainland China, were community-dwelling, and did not have a dementia diagnosis.

MEASUREMENTS

The tripartite model of attitudes was used to guide the semi-structured interview design and report the results. Thematic qualitative analysis was employed.

RESULTS

In both groups, most participants held negative feelings, stigmatized views and negative stereotypes of dementia. However, most participants expressed a willingness to help individuals living with dementia. Regarding dementia care, nearly all participants preferred home care but thought formal care would become the mainstream form of care in the future. Fewer Melbourne participants expressed concerns regarding developing dementia, were interested in dementia, or perceived a need for dementia-related educational activities. Melbourne participants also reported more avoidant responses to dementia or individuals living with dementia.

CONCLUSION

This study carefully compares attitudes towards dementia between older Chinese immigrants in Melbourne and older Chinese adults in Beijing. Similarities and differences were observed between these two groups. Dementia-related service providers should consider the sociocultural changes and migration-related barriers experienced by Chinese immigrants.

Knowledge, Attitudes, and Perceptions Toward Dementia Among Middle-Aged Singapore Residents

Background: Dementia is the decline in cognitive function sufficient to impair one’s accustomed functioning. Countries with aging populations, such as Singapore, face rising rates of dementia. Dementia patients and their caregivers endure great financial and emotional stress. With the broad aim of minimizing these stresses, this study provides a cross-sectional view of the knowledge, attitudes, and perceptions (KAP) towards dementia in middle-aged Singaporean residents. Objective: We aim to examine 1) the associations between demographic correlates and KAP; and 2) the effect of dementia knowledge on attitudes and perceptions towards dementia. Methods: An online anonymous cross-sectional questionnaire was administered to Singaporeans and Permanent Residents aged 45 to 65 years old in English, Mandarin, and Malay. Knowledge was evaluated across three domains: symptoms, risk factors, and management. Total and domain scores were dichotomized as good or poor knowledge using median cut-offs. Attitudes/perceptions across six domains were evaluated on Likert scales, and responses to each question were dichotomized into positive or negative attitudes/perceptions. Results: From 1,733 responses, 1,209 valid complete responses were accepted (mean age±SD 54.8±5.12 years old, females = 69.6%). Lower socioeconomic status was associated with poorer knowledge and greater barriers to risk-mitigating lifestyle modifications. Lack of personal experience with dementia and poor knowledge were also associated with erroneous attitudes/perceptions. Conclusion: Socioeconomic status and personal experience affect KAP towards dementia. Policy and education campaigns to address KAP towards dementia should account for baseline differences across demographics, for greater improvements in dementia incidence and support.

Home-dwelling older adults' attitudes and perceptions of dementia: A Q-methodological study in South Korea

AIM

Older adult attitudes and perceptions of dementia can have a major impact on early diagnosis, efforts to prevent and appropriately treat it, as well as being a family burden. The aim of this study is to explore attitudes and perceptions of dementia of home-dwelling older adults using Q-methodology.

METHOD

A total of 42 adults, age 65 or over, who live in South Korea ranked 37 Q statements about their attitudes and perceptions of dementia into A Q sort table grid.

RESULTS

The following three distinct viewpoints were extracted: (1) it is my responsibility to prevent and to care about dementia (family-centered view); (2) there are no ways to treat dementia (despairing views); and (3) dementia is a national responsibility (nation-centered view).

CONCLUSION

Based on these results, central and local government and communities should work together with older adults to manage dementia and reflect these three viewpoints when developing systematic dementia management programs.
