RESUMO
BACKGROUND: Air pollution has been recognised as a potential risk factor for dementia. Yet recent epidemiological research shows mixed evidence. The aim of this study is to investigate the longitudinal associations between ambient air pollution exposure and dementia in older people across five urban and rural areas in the UK. METHODS: This study was based on two population-based cohort studies of 11329 people aged ≥ 65 in the Cognitive Function and Ageing Study II (2008-2011) and Wales (2011-2013). An algorithmic diagnosis method was used to identify dementia cases. Annual concentrations of four air pollutants (NO2, O3, PM10, PM2.5) were modelled for the year 2012 and linked via the participants' postcodes. Multistate modelling was used to examine the effects of exposure to air pollutants on incident dementia incorporating death and adjusting for sociodemographic factors and area deprivation. A random-effect meta-analysis was carried out to summarise results from the current and nine existing cohort studies. RESULTS: Higher exposure levels of NO2 (HR: 1.04; 95% CI: 0.94, 1.14), O3 (HR: 0.90; 95% CI: 0.70, 1.15), PM10 (HR: 1.17; 95% CI: 0.86, 1.58), PM2.5 (HR: 1.41; 95% CI: 0.71, 2.79) were not strongly associated with dementia in the two UK-based cohorts. Inconsistent directions and strengths of the associations were observed across the two cohorts, five areas, and nine existing studies. CONCLUSIONS: In contrast to the literature, this study did not find clear associations between air pollution and dementia. Future research needs to investigate how methodological and contextual factors can affect evidence in this field and clarity the influence of air pollution exposure on cognitive health over the lifecourse.

BACKGROUND: High salt intake has been proposed as a risk factor for dementia. However, causal relationship between salt intake and dementia remains uncertain. PURPOSE: The aim of this study was to employ a mendelian randomization (MR) design to investigate the causal impact of salt intake on the risk of dementia. METHODS: Genome-wide association study (GWAS) data of exposures and outcomes (any dementia, cognitive performance, different types of dementia, Alzheimer's disease [AD], and Parkinson's disease) were obtained from the IEU database. MR estimates were generated though inverse-variance weighted model. MR-Egger, weighted median, and MR-Pleiotropy Residual Sum and Outlier (MR-PRESSO) method also used in our study. Sensitivity analyses included Cochran's Q test, MR-Egger intercept, MR-PRESSO global test and outlier test, leave-one-out analysis, and funnel plot assessment. RESULTS: Our MR analysis provided evidence of a causal association between high salt added to food and dementia (odds ratio [OR] = 1.73, 95% confidence interval [CI]: 1.21-2.49, and p = .003), dementia in AD (OR = 2.10, 95% CI: 1.15-3.83, and p = .015), and undefined dementia (OR = 2.61, 95% CI: 1.26-5.39, and p = .009). Higher salt added was also associated with increased risk of AD (OR = 1.80, 95% CI: 1.12-2.87, and p = .014) and lower cognitive performance (ß = -.133, 95% CI: -.229 to -.038, and p = .006). CONCLUSION: This study provides evidence suggesting that high salt intake is causally associated with an increased risk of developing dementia, including AD and undefined dementia, highlighting the potential importance of reducing salt consumption as a preventive measure.

INTRODUCTION: With an aging population and a growing prevalence of people living with dementia, the demand for best-practice dementia care in general practice increases. There is an opportunity to better utilise the nurse role within the primary care team to meet this increasing demand in the provision of care for people living with dementia. However, general practice nurses have limited knowledge in the provision of best-practice care for people living with dementia and their carer(s). A number of best-practice dementia care recommendations contained in the Australian Clinical Practice Guidelines and Principles of Care for People with Dementia have been identified as highly relevant to the role of the general practice nurse. AIMS: To explore general practice nurses' perspectives on published best-practice dementia care recommendations relevant to their role and identify barriers and facilitators to their implementation into clinical practice. METHODS: Thirteen Australian general practice nurses took part in this qualitative interview study. The research questions for this study were addressed within a paradigmatic framework of social constructionism. Data were transcribed verbatim and thematically analysed. RESULTS: There was a high level of agreement between general practice nurses that the recommendations were important, reflected best-practice dementia care and were relevant to their role. However the recommendations were perceived as limited in their usefulness to nurses' clinical practice due to being too vague and lacking direction. Four main themes were identified describing barriers and facilitators to operationalising best-practice dementia care.: creating a comfortable environment; changing approach to care; optimising the general practice nurse role and working collaboratively. Nine sub-themes were described: physical environment; social environment; complexity of care; care planning for the family; professional role and identity, funding better dementia care, education, networking and resources; different roles, one team; and interagency communication. CONCLUSION: This study identified several factors that need addressing to support general practice nurses to integrate best-practice dementia care recommendations into daily clinical practice. The development of interventions needs to include strategies to mitigate potential barriers and enhance facilitators that they perceive impact on their delivery of best-practice care for people living with dementia and their carer(s). The knowledge gained in this study could be used to develop multi-faceted interventions informed by theoretical implementation change models to enable the general practice nurse to operationalise best-practice dementia care recommendations.

This paper provides and overview of the community support services that may be available for people with dementia and their family carers. The authors introduce dementia, including the impact of the diagnosis on both the person with dementia and the wider family. Using a case study approach, the authors describe the support available, spanning health and social care and third sector organisations. They discuss how this support can enable people with dementia and their carers to maintain wellbeing and cope with the impact of dementia. This article will be of interest to community nurses, and health and social care professionals more generally, who may encounter families affected by dementia in community settings. Having a good knowledge of the support available and how to access it will allow community nurses to capitalise on the health promotion opportunities presented to them, when they come into contact with families affected by dementia in the course of their day-to-day practice.

BACKGROUND: Remote monitoring technologies show potential to help health professionals deliver preventative interventions which can avoid hospital admissions and allow patients to remain in a home setting. AIMS: To assess whether an Internet of Things (IoT) driven remote monitoring technology, used in the care pathway of community dementia patients in North Warwickshire improved access to care for patients and cost effectiveness. METHOD: Patient level changes to anonymised retrospective healthcare utilisation data were analysed alongside costs. RESULTS: Urgent care decreased following use of an IoT driven remote monitoring technology; one preventative intervention avoided an average of three urgent interventions. A Chi-Square test showing this change as significant. Estimates show annualised service activity avoidance of £201,583 for the cohort; £8764 per patient. CONCLUSIONS: IoT driven remote monitoring had a positive impact on health utilisation and cost avoidance. Future expansion of the cohort will allow for validation of the results and consider the impact of the technology on patient health outcomes and staff workflows.

BACKGROUND: Resource and economic constraints limit access to health care in rural populations, and consequently, rates of chronic illnesses are higher in this population. Further, little is known about how rural populations adopt active and healthy lifestyle behavior for dementia prevention. OBJECTIVES: This study aimed to explore the impact of modification in lifestyle behaviors on changes in cognitive function among middle-aged and older adults living in a rural area of Taiwan. DESIGN: In this prospective longitudinal study, changes in lifestyle and cognitive function were compared between the experimental and control groups. SETTING: Six rural community care stations were randomly cluster sampled in southern Taiwan. PARTICIPANTS: A total of 155 participants were enrolled and classified into two groups according to their community activity participation rate (CAPR). The control group (n=68) had a CAPR < 1x/month, and the experimental group (n=87) had a CAPR ≥ 1x/month. MEASUREMENTS: Cognitive function of the participants was measured using the MMSE scale. Lifestyle behaviors were measured using a self-designed questionnaire based on the Transtheoretical Model. RESULTS: From 2018-2020, the experimental group successfully maintained a healthy lifestyle. The MMSE score in the experimental group was significantly higher in the 3rd year than that in the control group (25.37 vs 22.56, p < 0.001). CONCLUSIONS: Sustainable community participation and adopting a healthy lifestyle could effectively maintain the cognitive function of the study participants. However, more needs to be done to support rural older adults to maintain a healthy diet and control their weight.

BACKGROUND: Burden of Alzheimer's disease (AD) and other dementias have grown rapidly over the decades, and high fasting plasma glucose (HFPG) was one of the well-established risk factors. It is urgently needed to estimate the global burden of AD and other dementias attributable to high fasting plasma glucose between regions, countries, age groups, and sexes to inform development of effective primary disease prevention strategies and intervention policies. METHODS: The burden of AD and other dementias attributable to HFPG was estimated based on a modeling strategy using the Global Burden of Disease Study 2019 dataset. The disease burden and time trend globally and by region, country, development level, age group, and sex were evaluated. RESULTS: The number of AD and other dementias-related deaths attributable to HFPG increased from 42,998.23 (95% uncertainty interval, UI: 4459.86-163,455.78, the year of 1990) to 159,244.53 deaths (95% UI 18,385.23-583,514.15, the year of 2019). The age-standardized death rate increased from 1.69 (95% UI 0.18-6.54) in 1990 to 2.24 (95% UI 0.26-8.24) in 2019. The burden was higher in more developed regions. The burden in women was double that in men, that HFPG-attributable AD and other dementias caused 99,812.79 deaths (95% UI 9005.67-387,160.60) in women and 59,431.74 deaths (95% UI 5439.02-214,819.23) in men, with age-standardized death rate of 2.27 (95% UI 0.20-8.79) per 100,000 population in women and 2.20 (95% UI 0.20-8.00) in men. CONCLUSION: Findings from the current study emphasizes the urgent requirement for targeted interventions in high-development regions, as well as the importance of proactive measures in middle-development countries in protection of AD and other dementias. The gender disparity necessitates the integration of gender-specific considerations in targeted approaches in prevention of AD and other dementias.

Dementia and incontinence are both prevalent in older age; yet, neither are an inevitable or normal part of ageing. It has been recognised that there is a skills and knowledge gap in professionals assessing and managing incontinence for people living with dementia. All too often, assumptions are made that incontinence is a symptom of dementia and that nothing can be done if a person living with dementia experiences episodes of incontinence. While dementia may impact on a person's ability to remain continent, it may not be the sole cause, and there may be treatments and strategies that can reduce the incidence in those affected. Therefore, a person-centred continence assessment should be undertaken to promote continence and reduce the impact of incontinence for people living with dementia and those who care for them. This paper will highlight some of the issues that are important for health and social care professionals to explore and identify, assess and manage incontinence to improve outcomes for families affected by dementia.

BACKGROUND: Getting a diagnosis of dementia does not equate to equitable access to care. People with dementia and unpaid carers face many barriers to care, which can vary within, and across, different countries and cultures. With little evidence across different countries, the aim of this scoping exercise was to identify the different and similar types of inequalities in dementia across Europe, and provide recommendations for addressing these. METHODS: We conducted a brief online survey with INTERDEM and INTERDEM Academy members across Europe, and with members of Alzheimer Europe's European Working Group of People with Dementia and Carers in February and March 2023. Members were asked about whether inequalities in dementia care existed within their country; if yes, to highlight three key inequalities. Responses on barriers were coded into groups, and frequencies of inequalities were calculated. Highlighted inequalities were discussed and prioritised at face-to-face and virtual consensus meetings in England, Ireland, Italy, and Poland, involving people with dementia, unpaid carers, health and social care providers, and non-profit organisations. RESULTS: Forty-nine academics, PhD students, people with dementia and unpaid carers from 10 countries (Belgium, Denmark, Germany, Greece, Ireland, Italy, Poland, Malta, Netherlands, UK) completed the survey. The most frequently identified inequalities focused on unawareness and lack of information, higher level system issues (i.e. lack of communication among care professionals), lack of service suitability, and stigma. Other barriers included workforce training and knowledge, financial costs, culture and language, lack of single-point-of-contact person, age, and living location/postcode lottery. There was general consensus among people living dementia and care providers of unawareness as a key barrier in different European countries, with varied priorities in Ireland depending on geographical location. CONCLUSIONS: These findings provide a first insight on dementia inequalities across Europe, generate cross-country learnings on how to address these inequalities in dementia, and can underpin further solution-focused research that informs policy and key decision makers to implement changes.

BACKGROUND: Recent findings suggest a link between gout and the development of dementia. Early treatment with colchicine is recommended as a first-line therapy for gout flares. Animal studies demonstrate that colchicine could induce cognitive impairment. This cohort study aimed to investigate the association between colchicine use and the risk of developing dementia. METHODS: In this nationwide cohort study, we performed comparative analysis on 6147 patients ≥40 years, with gout and colchicine new users against 6147 controls to assess subsequent dementia risk. The colchicine group and the control group (urate lowering therapy group) were matched on the bases of age, sex, index year, and comorbidities. All participants were followed for up to 14 years for a diagnosis of dementia considering medical records were retrospectively checked over this period. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Sensitivity analyses were performed to validate our findings. RESULTS: The adjusted hazard ratio (aHR) of dementia for colchicine users was 1.45 (95% CI = 1.05, 1.99) relative to comparison group after adjusting for sex, age, and comorbidities. Sensitivity analysis aiming to minimize underdiagnosed occult dementia at the time of index year yielded consistent positive association. In higher accumulative dose colchicine group (cumulative defined daily dose [cDDD] >30), the aHR of dementia risk for colchicine users was 1.42 (95% CI = 1.03, 1.97) compared with nonusers. For those duration of colchicine use >30 days, the aHR was 1.53 (95% CI = 1.01-2.32) compared to the nonuser group. CONCLUSIONS: A significant risk of dementia was observed in this study in patients with gout using colchicine at higher cDDD and for a longer period. Further research is needed to elucidate the relationship between colchicine, gout, and dementia.

BACKGROUND: Serum-measured fragments of Tau cleaved by ADAM-10 (Tau-A) and Caspase-3 (Tau-C) have been found linked to change in cognitive function and risk of dementia. OBJECTIVES: 1) To determine the discriminatory abilities of Tau-A, and Tau-C in subjects with either mild cognitive impairment (MCI) due to Alzheimer's disease (AD) or AD dementia compared to a control group. 2) To determine if there is a relation between Tau-A, and Tau-C and established cerebrospinal fluid (CSF) markers of AD- ß-Amyloid1-42 (AB42), Phosphorylated-tau-181 (p-tau), and total-tau. 3) To determine if Tau-A and Tau-C are associated with progression rate from MCI due to AD to AD dementia. DESIGN: Cross-sectional and a substudy using a retrospective cohort design. SETTING: Memory clinic derived subjects contributing to the Danish Dementia Biobank. PARTICIPANTS: Cognitively unimpaired subjects (n=49), patients with mild cognitive impairment (MCI) due to AD (n=45), and Alzheimer's dementia (n=52). MEASUREMENTS: Competitive enzyme-linked immunosorbent assay (ELISA)-measured serum levels of Tau-A, and Tau-C. RESULTS: The ratio between Tau-A and Tau-C differed between the three groups (p=0.015). Age- and sex-adjusted Tau-A differed between groups with lower ratios being associated with more severe disease (p=0.023). Tau-C was trending towards significant correlation to CSF-levels of AB42 (Pearson correlation coefficient 0.164, p=0.051). Those with Tau-C-levels in the 2nd quartile had a hazard ratio (HR) of 2.91 (95% CI 1.01 - 8.44, p=0.04) of progression compared to those in the 1st quartile. Those in the 3rd quartile was found to have a borderline significant (p=0.055) HR of 2.63 (95% CI 0.98 - 7.05) when compared to those in the lowest quartile. CONCLUSIONS: Tau-A and the ratio between Tau-A and Tau-C showed significant differences between groups and were correlated to CSF-AB42. Tau-C values in the middle range were associated with faster progression from MCI to dementia. This pilot study adds to the mounting data suggesting serum-measured Tau-A and Tau-C as biomarkers useful in relation to diagnosis and progression rate in AD but need further validation.

Many people in the advanced stages of dementia require full-time caregivers, most of whom are family members who provide informal (non-specialized) care. It is important to provide these caregivers with high-quality information to help them understand and manage the symptoms and behaviors of dementia patients. This study aims to evaluate ChatGPT, a chatbot built using the Generative Pre-trained Transformer (GPT) large language model, in responding to information needs and information seeking of such informal caregivers. We identified the information needs of dementia patients based on the relevant literature (22 articles were selected from 2442 retrieved articles). From this analysis, we created a list of 31 items that describe these information needs, and used them to formulate 118 relevant questions. We then asked these questions to ChatGPT and investigated its responses. In the next phase, we asked 15 informal and 15 formal dementia-patient caregivers to analyze and evaluate these ChatGPT responses, using both quantitative (questionnaire) and qualitative (interview) approaches. In the interviews conducted, informal caregivers were more positive towards the use of ChatGPT to obtain non-specialized information about dementia compared to formal caregivers. However, ChatGPT struggled to provide satisfactory responses to more specialized (clinical) inquiries. In the questionnaire study, informal caregivers gave higher ratings to ChatGPT's responsiveness on the 31 items describing information needs, giving an overall mean score of 3.77 (SD 0.98) out of 5; the mean score among formal caregivers was 3.13 (SD 0.65), indicating that formal caregivers showed less trust in ChatGPT's responses compared to informal caregivers. ChatGPT's responses to non-clinical information needs related to dementia patients were generally satisfactory at this stage. As this tool is still under heavy development, it holds promise for providing even higher-quality information in response to information needs, particularly when developed in collaboration with healthcare professionals. Thus, large language models such as ChatGPT can serve as valuable sources of information for informal caregivers, although they may not fully meet the needs of formal caregivers who seek specialized (clinical) answers. Nevertheless, even in its current state, ChatGPT was able to provide responses to some of the clinical questions related to dementia that were asked.

Importance: Age-standardized dementia mortality rates are on the rise. Whether long-term consumption of olive oil and diet quality are associated with dementia-related death is unknown. Objective: To examine the association of olive oil intake with the subsequent risk of dementia-related death and assess the joint association with diet quality and substitution for other fats. Design, Setting, and Participants: This prospective cohort study examined data from the Nurses' Health Study (NHS; 1990-2018) and Health Professionals Follow-Up Study (HPFS; 1990-2018). The population included women from the NHS and men from the HPFS who were free of cardiovascular disease and cancer at baseline. Data were analyzed from May 2022 to July 2023. Exposures: Olive oil intake was assessed every 4 years using a food frequency questionnaire and categorized as (1) never or less than once per month, (2) greater than 0 to less than or equal to 4.5 g/d, (3) greater than 4.5 g/d to less than or equal to 7 g/d, and (4) greater than 7 g/d. Diet quality was based on the Alternative Healthy Eating Index and Mediterranean Diet score. Main Outcome and Measure: Dementia death was ascertained from death records. Multivariable Cox proportional hazards regressions were used to estimate hazard ratios (HRs) and 95% CIs adjusted for confounders including genetic, sociodemographic, and lifestyle factors. Results: Of 92â¯383 participants, 60â¯582 (65.6%) were women and the mean (SD) age was 56.4 (8.0) years. During 28 years of follow-up (2â¯183â¯095 person-years), 4751 dementia-related deaths occurred. Individuals who were homozygous for the apolipoprotein ε4 (APOE ε4) allele were 5 to 9 times more likely to die with dementia. Consuming at least 7 g/d of olive oil was associated with a 28% lower risk of dementia-related death (adjusted pooled HR, 0.72 [95% CI, 0.64-0.81]) compared with never or rarely consuming olive oil (P for trend < .001); results were consistent after further adjustment for APOE ε4. No interaction by diet quality scores was found. In modeled substitution analyses, replacing 5 g/d of margarine and mayonnaise with the equivalent amount of olive oil was associated with an 8% (95% CI, 4%-12%) to 14% (95% CI, 7%-20%) lower risk of dementia mortality. Substitutions for other vegetable oils or butter were not significant. Conclusions and Relevance: In US adults, higher olive oil intake was associated with a lower risk of dementia-related mortality, irrespective of diet quality. Beyond heart health, the findings extend the current dietary recommendations of choosing olive oil and other vegetable oils for cognitive-related health.

Cognitive impairment, which is highly prevalent, especially among older people, leads to a decrease in the quality of life of patients, impairment of daily activities, and an increased risk of dementia and mortality. Currently, much attention is paid to mild cognitive impairment. The article discusses diagnostic criteria and possible clinical variants of this syndrome. Given the high rate of progression of mild cognitive impairment to dementia, it is necessary to identify risk groups and carry out therapeutic preventive measures. Correction of potentially modifiable risk factors is considered as a promising direction of therapy. Sufficient physical and mental activity, proper diet, normalization of sleep, visual acuity and hearing are necessary. Preventing stroke and controlling vascular risk factors may reduce the risk of mild cognitive impairment progressing to dementia.

Dementia is one of the main challenges to modern society. According to estimated data, as of 2019, there were 1.949.811 people living In Russia with dementia of various etiology. At the same time, there have been no large epidemiological studies of dementia in the Russian Federation. The article provides an overview of the available data on the epidemiology of cognitive impairment (CI) In Russia given from various sources. Not only estimated, but also available clinical data were analyzed. In general, the obtained prevalence values for CI are comparable to global values. Thus, in an epidemiological study of people over 60 years of age in a separate district of Moscow, the prevalence of dementia was 10.4%, Alzheimer's disease 4.5%. A study of outpatients aged 60 years and older showed a high prevalence of both dementia and non-dementia CI at general medical appointments (incidence of dementia 7.8%, MCI 49.6%). It has been shown that the problem of non-dementia CI is already relevant in people of pre-retirement age (the prevalence of non-dementia CI in patients 55-64 years old is 36.8-44.8%). Unique data obtained in a population of institutionalized centenarians (prevalence of dementia 69%), as well as data on the relationship of CI with both somatic and demographic factors are presented.
