Public Awareness of Alzheimer’s Disease: A Cross-Sectional Study from Saudi Arabia

The prevalence of Alzheimer's disease among diabetic patients in Saudi Arabia

OBJECTIVES

To investigate the knowledge of Alzheimer's disease (AD) among 228 Saudi adults with diabetes, aiming to assess cognitive awareness through a questionnaire. It explores risk factors, symptoms, prevention strategies, and attitudes towards dementia, while integrating demographic data to illuminate cognitive landscapes and correlations between diabetes and cognitive health.

METHODS

Trained dietitians administered questionnaires to 228 adult Saudi diabetic participants, focusing on their understanding of AD across various domains. The study employed validated tools for data collection and amalgamated responses with demographic and medical details.

RESULTS

Of the 228 participants, 56.6% were female. Findings revealed a high acknowledgment of 3 subdomains of the Alzheimer's disease knowledge scale (ADKS) - risk factors, course, and diagnosis - with 75% agreement. However, lower acknowledgment rates with agreements were observed in the domains of life impact (71%), symptoms (71%), caregiving (72%), and treatment management (69%). Statistical analysis indicated significant differences in knowledge based on education levels (p≤0.05), with university-educated individuals demonstrating greater agreement across all ADKS subdomains.

CONCLUSION

The research highlights the need for enhanced awareness of AD among Saudi diabetic individuals. By integrating healthcare, education, and culturally sensitive interventions, the study advocates for targeted education to improve understanding of cognitive health and effective management strategies in this demographic, emphasizing the role of educational background in shaping perceptions.

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.

Perception and attitude of the general population toward Alzheimer's disease in eastern region, Saudi Arabia

Objectives

To measure the awareness of AD among the general population of Eastern Province, Saudi Arabia.

Methods

A cross-sectional study was conducted in the Eastern Province of Saudi Arabia from October to November 2023. The data was collected using an online questionnaire.

Results

A total of 614 eligible participants completed the study questionnaire. Among those surveyed, 99.3% had heard about Alzheimer's disease (AD), while 96.1% associated it with memory loss. Additionally, 91.5% recognized that individuals with AD face risks when driving, 91.5% believed they could not independently handle their financial matters, 85.7% thought they could not make health-related decisions on their own, and 85.5% believed they could still participate in sports.

Conclusion

The research results challenge our initial hypothesis by revealing significant AD awareness in Eastern Province, Saudi Arabia, largely attributed to internet-based health information. Despite this, there is a need to improve public attitudes toward Alzheimer's patients, highlighting the importance of enhanced education and better communication between healthcare professionals and the public.

Heterogeneity in the level of dementia literacy among community doctors in China: A latent profile analysis

Background

This study aimed to explore the heterogeneity of community doctors based on their knowledge of dementia and the potential factors associated with their dementia literacy.

Methods

A total of 1288 community doctors completed the Alzheimer disease knowledge scale (ADKS) in a cross-sectional study conducted between December 2021 and January 2022. We used latent class analysis (LCA) to explore potential clusters based on responses to the ADKS. Multivariate multinomial logistic regression analysis was performed to evaluate the associations between potential risk factors and the knowledge of community doctors.

Results

Community doctors were divided into four clusters according to their knowledge structure (Akaike information criterion (AIC) = 35672.83, Bayesian information criterion (BIC) = 36307.63, adjusted BIC (aBIC) = 35916.91, entropy = 0.814): the severity-focused subgroup (n = 269), the physical issues-focused group (n = 370), the knowledge uncertainty group (n = 191), and the general-focused group (n = 458). Age, education level, type of practice, and professional title were associated with the knowledge structure of Alzheimer's disease (AD). In addition, the perception that patients seek care in community health centres for physical reasons and community doctors' failure to manage patients with recently identified cognitive impairment were associated with the structures of the ADKS among community doctors (P < 0.05).

Conclusions

There is heterogeneity in the level of AD knowledge among community doctors and their demographic characteristics, perceptions, and practices. Further efforts are needed to optimise the knowledge structure of dementia among community health care professionals.

Knowledge of Alzheimer's disease and associated factors among adults in Zhuhai, China: a cross-sectional analysis

BACKGROUND

This study aimed to assess the public knowledge regarding Alzheimer's Disease (AD) in Zhuhai, China, focusing on identifying knowledge gaps and the influence of demographic and health factors.

METHODS

A cross-sectional study was conducted in Zhuhai, China, from October to November 2022. A total of 1986 residents from 18 communities were selected employing stratified multi-stage equi-proportional sampling. Questionnaires covering general information and the Alzheimer's Disease Knowledge Scale (ADKS) were investigated face-to-face. Ordinal multiclass logistic regression was applied to assess the relationship between AD awareness and demographic and health characteristics.

RESULTS

The average ADKS score was 18.5 (SD = 3.36) in Zhuhai. The lowest awareness rates were observed in the "Symptoms" and "Caregiving" subdomains of ADKS, with rates of 51.01% and 43.78%, respectively. The correct rates for the 30 ADKS questions ranged from 16.62 to 92.6%, showing a bimodal pattern with clusters around 80% and 20%. Women (OR = 1.203, 95% CI: 1.009-1.435), individuals aged 60 years or older (OR = 2.073, 95% CI: 1.467-2.932), those living in urban areas (OR = 1.361, 95% CI: 1.117-1.662), higher average monthly household income per capita (OR = 1.641, 95% CI: 1.297-2.082), and without any neurological or mental disorders (OR = 1.810, 95% CI: 1.323-2.478) were more likely to have higher levels of awareness about Alzheimer's disease.

CONCLUSIONS

Adults in Zhuhai show a limited knowledge of AD, particularly in the 'Symptoms' and 'Caregiving' subdomains. Upcoming health campaigns must focus on bridging the knowledge gaps in different subdomains of AD, especially among subgroups with lower awareness, as identified in our study.

Public Awareness, Knowledge, and Attitude Toward Alzheimer's Disease in Makkah, Saudi Arabia

BACKGROUND

Alzheimer's disease is a neurodegenerative disease that slowly deteriorates cognitive function over time. This condition disables the geriatric population worldwide. Knowing its symptoms and presentation could help the general population seek medical attention early.

OBJECTIVE

This study aims to assess the level of awareness, knowledge, and attitude towards Alzheimer's disease among the general population in Makkah City.

METHODS

This cross-sectional study employed an online questionnaire distributed randomly in Makkah, Saudi Arabia. A sociodemographic and attitude panel is included under each section of the questionnaire, as well as a knowledge panel based on the Alzheimer's Disease Knowledge Scale (ADKS). The knowledge and awareness level regarding Alzheimer's disease was determined by adding up discrete scores for each correct knowledge item. A participant's awareness level was categorized as poor if their score was less than 60%. Participants whose scores were 60% or higher were considered to have a high level of awareness Results: A total of 545 participants were investigated; 316 (58%) were females. A range of ages was represented among the participants, from 18 to over 60. Of the study respondents, 68 (12.5%) had an overall good awareness and knowledge of Alzheimer's disease and its management while 477 (87.5%) had a poor knowledge level. Among divorced/widowed participants, 16.2% had an overall good knowledge level of the disease compared to 8.3% of married respondents with recorded statistical significance (P=.049). Also, 20.4% of those with relatives diagnosed with Alzheimer's disease had good knowledge of the disease versus 10.7% of others without (P=.009).

CONCLUSION

According to the results, there is a lack of awareness and knowledge of Alzheimer's disease. This study suggests increasing public awareness and knowledge of Alzheimer's disease through campaigns and public education so that the disease is detected earlier.
