Aim s : The objective of this study was to examine the relationship between caregiving burden and pre‐death grief, with a specific focus on adult‐child caregivers in mainland China. Additionally, the study explored whether coping strategies played a mediating role in this correlation. Methods: A convenience sample of 320 adult‐child caregivers of older parents with dementia from Kunming, mainland China, was recruited for the study. Data were collected using the Chinese version of the Marwit‐Meuser Caregiver Grief Inventory‐Short Form, the Burden Scale for Family Caregivers, and the Ways of Coping Checklist‐Revised. Results: Results using linear regression and multiple mediation analysis with Hayes' process model indicated that caregiving burden was positively related to pre‐death grief and that active coping mediated the relationship between them. In the female group, active coping partially mediated the association between caregiving burden and pre‐death grief, but in the male group, this mediating effect did not exist. Conclusion: The study found evidence supporting the link between caregiving burden and pre‐death grief among adult‐child caregivers of older parents with dementia in mainland China. Furthermore, the caregiving burden prevented the use of active coping, and this decrease in coping increased the perception of pre‐death grief. These associations only existed in the female group. Implications: This paper presented the importance of active coping skills in the dementia caregiving process. Impact: The findings of this study emphasize the necessity for health practitioners to provide targeted interventions regarding pre‐death grief among dementia caregivers and strengthen caregivers' active coping strategies to reduce their pre‐death grief. Community‐based and personal care support services should be promoted to alleviate their caregiving burden. Reporting Method: We have adhered to the transparent reporting of evaluations with quantitative design statements and the corresponding checklist was followed. Patient or Public Contribution: 'No patient or public involvement'. [ABSTRACT FROM AUTHOR]

Accessible Summary: What is known on the subject?: Physical restraint is widely used in the elderly at home, and cognitive impairment is an important risk factor. Family caregivers of people with dementia are the main decision makers and implementers of physical restraint at home.Most people with dementia in China receive home care, and family caregivers face enormous care and moral pressures influenced by Confucian culture.Current research on physical restraints focuses on quantitative analysis of its prevalence and reasons within the institutions. There is little research on how family caregivers perceive physical restraints in home care context, especially under Chinese culture. What the paper adds to existing knowledge?: Many family caregivers face approach – avoidance conflict and moral dilemmas when making decisions to restrain, and they make difficult choices in these dilemmas.In China, family caregivers are influenced by many unique factors, including traditional Confucian culture, family affection, and rural home environment.Inadequate laws and policies provide the ground for abuse of physical restraints, and family caregivers rarely consider legal and policy restrictions when using physical restraints. What are the implications for practice?: With limited medical resources, nurse‐led dementia management is the hope to reduce physical restraints in home.Mental health nurses need to assess for the appropriateness of physical restraints associated with psychiatric symptoms in people with dementia.At both organizational and community levels, improving effective communication and relationships between professionals and family caregivers are important to address. Improvements in this context require education and time for staff to develop skills and experience which is necessary to provide family caregivers with ongoing information and psychological support within their communities.Considering Confucian culture will be of value for mental health nurses working in other countries where there are Chinese communities to better understand perceptions of family caregivers. Introduction: The use of physical restraints is a common practice in home care. Family caregivers face care‐related and moral pressures due to the influence of Confucian culture in China. The use of physical restraints in the Chinese cultural environment may differ from the use of such restraints in other cultures. Scientific Rationale: Current research on physical restraints focuses on quantitative analysis of its prevalence and reasons within the institutions. However, there is little research on how family caregivers perceive physical restraints in home care context, especially under Chinese culture. Aim: To explore the perceptions of family caregivers on physical restraints in people diagnosed with dementia receiving home care. Method: A descriptive, qualitative study of Chinese family caregivers of people diagnosed with dementia in home care. Framework method analysis was adopted using the multilevel socio‐ecological model. Results: Beliefs about benefit lead to a dilemma for family caregivers. Cherishing family's affection encourages caregivers to reduce physical restraints, but lack of help from family members, professionals and the community forces them to restrain their loved ones. Discussion: Future research should explore the complex issue of culturally specific physical restraints decisions. Implications for Practice: Mental health nurses must receive education regarding the negative outcomes of the use of physical restraints for family members of people diagnosed with dementia. A more liberal approach to mental health and relevant legislation, which is an emerging global phenomenon that is currently in an early phase of development in China, grants human rights to people diagnosed with dementia. Effective communication and relationships between professionals and family caregivers can contribute to the establishment of a dementia‐friendly community in China. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to describe levels of social support and explore the factors predictive of social support for Chinese family caregivers of patients with dementia. Background: Social support levels and their predictive factors in Chinese dementia caregivers have not been well documented, which need to be further clarified to provide a basis for creating effective social support strategies. Methods: This was a cross‐sectional study with 91 participants who completed a demographic questionnaire and the Social Support Rating Scale from 2015 to 2016. Results: Chinese family caregivers of patients with dementia received moderate social support. Caregivers' subjective support domain scores and support utilization domain scores were significantly lower than those of the normal Chinese population, whereas caregivers' total social support scores were higher than those of the normal Chinese population. Family caregivers' monthly household income, educational level and place of residence were predictors of their own social support. Conclusion: Social support in Chinese caregivers of patients with dementia needs to be improved, especially the subjective support and support utilization. Healthcare professionals should pay special attention to caregivers with a lower monthly household income and educational level and caregivers who lived in the suburban area. Summary statement: What is already known about this topic? Social support is important for family caregivers of patients with dementia.Social support levels and their predictive factors in Chinese dementia caregivers have not been well documented. What this paper adds? Caregivers' subjective support and support utilization were significantly lower than the normal Chinese population; caregivers' total social support was significantly higher than the normal Chinese population.The best predictors of caregivers' social support were the monthly household income, educational level and place of residence of the caregivers. The implications of this paper: Healthcare professionals should pay special attention to caregivers with a lower monthly household income and educational level and caregivers who lived in the suburban area.Future research is needed to create effective nursing regimes, paying attention to caregivers with a lower educational level and caregivers who lived in the suburban area.

Background: Dementia is a progressive neurodegenerative condition, while metabolic syndrome (MetS) is characterized by a combination of metabolic abnormalities such as hypertension, high blood sugar, and obesity. There exists a connection and overlap between the two conditions in certain aspects, and both are influenced to varying degrees by the process of aging. This study presents an overview of the current research landscape regarding dementia and MetS through bibliometric analysis. Methods: A systematic search was conducted to retrieve relevant literature on dementia and MetS published between 1 January 2000, and 30 November 2023, from the Web of Science Core Collection database. Various bibliometric tools, including VOSviewer, CiteSpace, and the R software package “bibliometrix,” were utilized for analysis. Results: A total of 717 articles were identified, showing an upward trend in annual publications. Leading contributors included the United States, Italy, and China, with institutions such as the University of California System at the forefront. The Journal of Alzheimer’s Disease emerged as the top publisher, while research published in Neurology garnered significant citations. Noteworthy authors encompassed Panza, Francesco; Frisardi, Vincenza; and Feldman, Eva L, with Kristine Yaffe being the most cited author (280 citations). Recent studies have focused on themes like “gut microbiota,” “neuroinflammation,” “fatty acids,” and “microglia.” Conclusion: This bibliometric analysis summarizes the foundational knowledge structure in the realm of dementia and MetS from 2000 to 2023. By highlighting current research frontiers and trending topics, this analysis serves as a valuable reference for researchers in the field. [ABSTRACT FROM AUTHOR]

Objectives: This systematic review and meta‐analysis aimed to determine the prevalence of loneliness and social isolation among informal carers of individuals with dementia and to identify potential influencing factors. Methods: We conducted a comprehensive search across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, CINAHL, Scopus, Chinese Biomedical, China National Knowledge Internet, and WANFANG. Our search strategy covered the inception of the databases up to September 16, 2023, with an updated search conducted on March 8, 2024. Prevalence estimates of loneliness and social isolation, presented with 95% confidence intervals, were synthesized through meta‐analysis. Subgroup analyses and meta‐regression were employed to explore potential moderating variables and heterogeneity. Results: The study encompassed 27 research papers involving 11,134 informal carers from 17 different countries. The pooled prevalence of loneliness among informal carers of individuals with dementia was 50.8% (95% CI: 41.8%–59.8%), while the pooled prevalence of social isolation was 37.1% (95% CI: 26.7%–47.6%). Subgroup analyses and meta‐regression indicated that various factors significantly influenced the prevalence of loneliness and social isolation. These factors included the caregiving setting, study design, the intensity of loneliness, geographical location (continent), data collection time, and the choice of assessment tools. Conclusions: This study underscores the substantial prevalence of loneliness and social isolation among informal carers of individuals with dementia. It suggests that policymakers and healthcare providers should prioritize the development of targeted interventions and support systems to alleviate loneliness and social isolation within this vulnerable population. Key points: Informal carers of people with dementia contend with unique circumstances that render them susceptible to both loneliness and social isolation.There is a significant prevalence of loneliness and social isolation in informal carers of individuals with dementia.Several significant moderators influence the prevalence of loneliness and social isolation among informal carers of individuals with dementia.Moderator analysis can guide targeted interventions and support systems for at‐risk informal carers of people with dementia to alleviate loneliness and social isolation.

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. [ABSTRACT FROM AUTHOR]

Aim: This study aimed to explore the experiences of family caregivers interacting with people with dementia. Background: A majority of people with mild‐to‐moderate dementia live at home with family caregivers. This interaction creates positive experiences and challenges for these caregivers. Design Descriptive phenomenological qualitative inquiry guided this study. Methods: This qualitative study involved semi‐structured interviews with the caregivers of people with mild‐to‐moderate dementia (n = 10). Data were collected from June to September 2018, and then data were thematically analysed. Results: Six categories of themes were identified from the interviews: (1) unexpected things often happen; (2) positive coping strategies; (3) sense of accomplishment because people with dementia actively participate in activities; (4) sense of frustration because of the reluctance of people with dementia to participate in activities; (5) hope for the happiness of people with dementia; and (6) want to have their own life. Conclusions: This study reveals that caregivers could positively interact with people with dementia through creating opportunities and arranging meaningful activities. Future research should focus on family management and training on how to help caregivers interact effectively with people with dementia. SUMMARY STATEMENT: What is already known about this topic? A majority of people with mild‐to‐moderate dementia live at home with family caregivers.Many caregivers suffer from depression, anxiety, fatigue, insomnia, family conflicts and low levels of life satisfaction.How caregivers interact with people with dementia at home remains unclear. What this paper adds? Caregivers experience various feelings, such as a sense of accomplishment and occasionally frustration, when interacting with people with dementia.Caregivers stated that they wanted people with dementia to be happy and live their life. Thus, the caregivers changed their attitude, accepted the situation and organized meaningful activities for people with dementia.Caregivers employed various strategies for handling situations involving people with dementia and shared how they interacted with such individuals. The implications of this paper: Care organizations that can offer certain services for people with dementia should be developed to lessen caregivers' burden.Community nurses should develop caregivers' strengths and enhance their abilities to improve interaction with people with dementia.Future research should focus on family management and training on how to help caregivers interact effectively with people with dementia.

Dementia has been cited as a critical public health risk in the contemporary world, while few empirical researchers try to reveal the casual relationship between air pollutant concentrations (APCs) and dementia, especially given the increasing prevalence of air pollution on a global scale. Accordingly, this paper tries to infer the causal relationship between APCs and dementia. The 59,605 valid data was compiled through a combination of the statistic from the China Family Panel Study, China Environmental Statistics Yearbook, World Meteorological Association and China National Bureau of Statistics. The RD design of this study utilizes the discontinuous variation in APCs and dementia as one crosses the Huai River boundary, which is an arbitrary heating policy that causes the significant difference in APCs between the north and south of China. We used stata17.0 to analyze the data. The results of the RD regression indicated that a 100 μ g/m3 rise in APCs led to an increase of 42.4% in the hazard ratio of suffering dementia (Coeff=-0.58, SD= 0.23, P < 0.05). Meanwhile, heterogeneous models revealed that the hazard ratio of suffering dementia by APCs was more significant in the older compared to younger (coeff= 1.35 vs coeff= 1.55, P < 0.05), male compared to female (coeff= 1.62 vs coeff= 0.71, P < 0.05), smoking compared to non-smoke (coeff= 2.12 vs coeff= 0.93, P < 0.05), and thin groups compared to medium and obesity (coeff= 2.05 vs coeff= 1.22, coeff= 1.28, P < 0.05). In addition, the O3 and SO2 were the air pollutants with the highest (coeff= 1.54, P < 0.05) and lowest effects (coeff= 0.81, P < 0.05) on the hazard ratio of suffering dementia among the five APCs, respectively. And the robustness of the results was ensured by changing the RD bandwidth, polynomial order. The results indicated that APCs significantly induced the hazard ratio of suffering dementia of Chinese residents, which provides empirical evidence in supporting the Chinese government to invest more in combating air pollution and ensure the public health of Chinese residents.

Aims and objectives: To establish an understanding of healthcare professionals' dementia knowledge and attitudes towards dementia care, and family carers' perceptions of dementia care in China. Background: Healthcare professionals and family carers of people with dementia deliver most of the dementia care in China. However, little research on healthcare professionals' dementia knowledge and attitudes towards dementia care, and family carers' dementia care perceptions has been conducted in China. Methods: An integrative review was conducted and reported based on the PRISMA guidelines and Whittemore and Knafl's framework. Eight English databases were searched without date restriction: CINAHL Plus with Full Text, MEDLINE, PubMed, Web of Science, Cochrane Library, Embase, PsycINFO and Scopus; and three Chinese databases: China National Knowledge Infrastructure, Chongqing Weipu and Wanfang, plus a manual search of reference lists. Results: Thirty‐eight primary research papers were included in the review. Three themes were identified from the synthesis: (a) knowledge and competency; (b) attitudes towards dementia care; and (c) carers' burden and unmet needs. Healthcare professionals' dementia knowledge ranged from low to moderate levels and attitudes towards dementia care were generally negative. With low levels of knowledge of dementia and negative attitudes including stigma, family carers were under stress with insufficient support, and they expected more support from community nurses. Conclusions: There is an apparent need for a national policy on healthcare professional education and training to improve dementia care practice in China. Such a policy may improve support services for family carers. Relevance to clinical practice: Nurses, and particularly community nurses, are well‐positioned to support family carers in China. However, healthcare professionals in China are not prepared for this. Therefore, education and training on dementia care should be integrated into medical and nursing undergraduate programmes and provided for healthcare professionals after commencing employment, and strategies to reduce stigma are needed.

Sensory activities are used to increase social engagement for people with dementia, who may struggle to participate in activities due to deteriorating cognitive functions. Sensory tools are used but these can be inappropriate since they are not designed for people with dementia. This paper details the design of an e-textile sensory tool for people with dementia, with stakeholders in Mainland China. The concept, a sensory wall, was derived from a previous co-design project in Hong Kong. However, the design context differs, and this work highlights barriers to implementing co-design in sensory tool design. Instead, this project took a collaborative customization approach. This paper describes the design processes and evaluations for the first and second sensory wall, with context on dementia care in Mainland China. This paper highlights considerations in the design of a sensory tool for people with dementia, and the benefits of stakeholder engagement in sensory tool design. [ABSTRACT FROM AUTHOR]

Zeng et al.'s Ethics Review highlights some of the challenges associated with clinical research in China. They found that only a minority of published clinical trials of anti-dementia drugs reported that they fulfilled the basic ethical principles as outlined in the Declaration of Helsinki. With recent reports of scientific misconduct from China, there is an urgent need to find approaches to compel researchers to adhere to ethical research practices. This problem does not call for a simple solution, but if forces are joined with governmental regulations, education in ethics issues for medical researchers, and strong reinforcement by Chinese journal editors not to publish studies with these flaws, then research ethics and publication standards will probably improve. Other solutions to foster ethical practice of drug trials are discussed including Chinese initiatives directed at managing conflict of interest from the pharmaceutical industry and educating clinical researchers.

Epimedii Herba (EH) is an herbal medicine originating from several plants of the genus Epimedium. It is a major therapeutic option for kidney yang deficiency syndrome, which is closely related to androgen hormones and also has been used to treat hemiplegia following a stroke in traditional medicine of Korea and PR China. To date, many clinical and basic researches of EH have shown the activities on functional recovery from brain diseases. Recently, neuroplasticity, which is the spontaneous reaction of the brain in response to diseases, has been shown to accelerate functional recovery. In addition, androgen hormones including testosterone are known to be the representative of neuroplasticity factors in the brain recovery processes. In this review, we described the neuro-pharmacological activities of EH, focusing on neuroplasticity. Thirty-three kinds of papers from MEDLINE/PubMed, EMBASE, and CNKI were identified and analyzed. We categorized the results into five types based on neuroplasticity mechanisms and presented the definition of each category and briefly described the results of these papers. Altogether, we can suggest that neuroplasticity is a novel viewpoint for guiding future brain research of EH and provide the evidence for the development of new clinical applications using EH in the treatment of brain diseases.

Objectives: No study has reported secular trends in dementia prevalence, all-cause mortality, and survival status in rural China. Methods: We established two cohorts (XRRCC1 and XRRCC2) in the same region of China, 17 years apart, to compare dementia prevalence, all-cause mortality, and survival status, and performed regression analysis to identify associated factors. Results: Dementia prevalence was 3.49% in XRRCC1 and 4.25% in XRRCC2, with XRRCC2 showing a significantly higher prevalence (OR = 1.79, 95%CI: 1.2-2.65). Allcause mortality rates for dementia patients were 62.0% in XRRCC1 and 35.7% in XRRCC2. Mortality in the normal population of XRRCC2 decreased by 66% compared to XRRCC1, mainly due to improved survival rates in women with dementia. Dementia prevalence was positively associated with age >65, spouse-absent status, and stroke, and negatively associated with =6 years of education. Conclusion: Dementia prevalence in rural China increased over 17 years, while mortality decreased. Major risk factors include aging, no spouse, and stroke, with higher education offering some protection. [ABSTRACT FROM AUTHOR]

Objectives: This paper provides an overview of the status of dementia care in Mainland China under the framework of the three‐tier long‐term care system proposed by the Chinese government, and gives the direction for service development. Methods: Official documents, annual reports of related associations, and studies conducted in Mainland China from 2006 to 2017, published both in English and Chinese were reviewed. Results: With the establishment of the three‐tier long‐term care system, the Government has invested a lot in long‐term care, and improvements have been made. However, specific areas of dementia care still face challenges. Discussion: Strategies in improving the long‐term care services have been achieved. These included training for informal caregivers at home settings, increased investment in community health centers, and increased institutional placements, etc. However, these are not enough to fulfill the needs of people with dementia and their caregivers. Implications for Nursing and Health Policy: Multiple levels of training and interaction within the framework of the three‐tier long‐term care system as well as more research are recommended for improving dementia care.

Background: Global research hotspots and future research trends in the neurobiological mechanisms of late-life depression (LLD) as well as its diagnosis and treatment are not yet clear. Objectives: This study profiled the current state of global research on LLD and predicted future research trends in the field. Methods: Literature with the subject term LLD was retrieved from the Web of Science Core Collection, and CiteSpace software was used to perform econometric and co-occurrence analyses. The results were visualized using CiteSpace, VOSviewer, and other software packages. Results: In total, 10,570 publications were included in the analysis. Publications on LLD have shown an increasing trend since 2004. The United States and the University of California had the highest number of publications, followed consecutively by China and England, making these countries and institutions the most influential in the field. Reynolds, Charles F. was the author with the most publications. The International Journal of Geriatric Psychiatry was the journal with the most articles and citations. According to the co-occurrence analysis and keyword/citation burst analysis, cognitive impairment, brain network dysfunction, vascular disease, and treatment of LLD were research hotspots. Conclusion: Late-life depression has attracted increasing attention from researchers, with the number of publications increasing annually. However, many questions remain unaddressed in this field, such as the relationship between LLD and cognitive impairment and dementia, or the impact of vascular factors and brain network dysfunction on LLD. Additionally, the treatment of patients with LLD is currently a clinical challenge. The results of this study will help researchers find suitable research partners and journals, as well as predict future hotspots. [ABSTRACT FROM AUTHOR]

Aim: To describe the lived experiences of family caregivers of individuals with dementia during the coronavirus disease (COVID‐19) outbreak in China. Design: This study used a descriptive phenomenological research method. Methods: Between May and September 2021, semi‐structured interviews were conducted with 22 family caregivers of people with dementia. Colaizzi's method was used for manual analysis. Results: Qualitative data revealed an overarching experience of finding 'There is always good fortune in misfortune to encourage us in coping with difficulties'. Three themes emerged: family reactions to the COVID‐19 outbreak, feeling supported by multiple resources performing respective functions and resilient adaptation to new situations. Conclusion: During the COVID‐19 outbreak, family caregivers of people living with dementia in China looked for positive aspects among difficulties and experienced corresponding reactions, social support resources and resilient adapted coping styles. Implications for the Profession and/or Patient Care: Nurses in China and other countries facing similar pandemic characteristics, cultures or economic development levels, can guide family caregivers to look at family hardships from a positive perspective, develop interventions to rapidly respond to families' reactions after a disaster and help them identify social support resources and form adapted coping styles. Impact: We identified the resilience and the positive experiences of Chinese family caregivers of individuals with dementia during the COVID‐19 outbreak. The results can inform countries with similar cultures and economic levels, offering measures to support their adaptation to pandemics. Reporting Method: This study followed the COREQ guidelines. Patient or Public Contribution: Family caregivers of people with dementia who met the inclusion criteria and who were interested in sharing their understanding of their experiences, participated in the study.

Background: Dementia has become one of the leading causes of death across the world. Aims: The aim of this study was to investigate the incidence, prevalence, and mortality of dementia in China between 2010 and 2020, and to investigate any geographical, age, and sex differences in the prevalence and incidence of dementia. Methods: Five databases were searched. The Joanna Briggs Institute (JBI) critical appraisal tool was used to assess the quality of the included studies. A random-effects meta-analysis was performed to estimate the pooled prevalence of dementia. Subgroup analysis was based on the type of dementia. The incidence and mortality of dementia were synthesized qualitatively. Results: A total of 19 studies were included. The meta-analysis showed that the prevalence of dementia was 6% (95%CI 5%, 8%), the prevalence of Alzheimer's disease (AD) was 5% (95%CI 4%, 6%), and the prevalence of vascular dementia (VaD) was 1% (95%CI 0%, 2%). The subgroup analysis showed that the prevalence rates of dementia in rural (6%, 95%CI 4%, 8%) and urban areas were similar (6%, 95%CI 4%, 8%). Deaths due to dementia increased over time. Conclusion: The prevalence, incidence, and mortality of dementia increased with age and over time. Applying consistent criteria to the diagnosis of cognitive impairment and dementia is necessary to help with disease monitoring. Promoting dementia knowledge and awareness at the community level is necessary. [ABSTRACT FROM AUTHOR]

Individual cognitive interventions for Alzheimer's disease have been shown to be beneficial and cost effective when evaluated as sole interventions. However, there is a need for a systematic, person-centric, structured approach to guide non-pharmacological intervention selection based on disease stage, symptoms, outcome assessment, and individual requirements. Our Structured Cognitive Intervention Pathway aims to facilitate the selection of first-line, or subsequent, non-pharmacological management for people with Alzheimer's disease living at home and in elderly care facilities. We discuss the Pathway's conceptual basis and evaluation of implementation as a decision-support tool within a dementia care service in China. [ABSTRACT FROM AUTHOR]

Background: Dementia is a serious and growing health problem, and since most people with dementia live at home, caring responsibilities generally fall on family members. Caregivers are often inadequately supported by formal health services and have poorer psychological and physical health. Our study aimed to compare the contributions of publications from different countries, institutions and authors and present a bibliometric analysis to determine the hotspots and trends in research concerning the health of and interventions for family dementia caregivers.Methods: Studies published during 1988-2018 were extracted from the Science Citation Index Expanded of the Web of Science. Each abstract of publications was evaluated to obtain the basic information. A bibliometric analysis was used to evaluate the number or cooperation networks of publications, countries, institutions, journals, citations, authors, references, and keywords. The resulting articles were analyzed descriptively, and the publication keywords were visualized using VOSviewer.Results: Five hundred forty-two articles were identified. The annual number of relevant publications has steadily increased since approximately 2006. The USA has the highest number of publications (36.2%), followed by the UK (12.9%). China entered the field late, but research conducted in China has rapidly developed. The most productive institution, journal, and author in this field are University College London, the Journal of the American Geriatrics Society, and Orrell M from the UK, respectively. A co-occurrence analysis of the keywords reveals a mainstream research focus on burden, depression, quality of life, and corresponding interventions for people with dementia caregivers. The keywords "psychosocial intervention", "long-term", "e-learning/online", "communication", and "qualitative research" reflect the latest hotspots, appearing in approximately 2017-2018.Conclusion: Our study details the performance statistics, main topics and trends research on the health of and interventions for dementia caregivers from 1988 to 2018 and provides a comprehensive analysis.

Objectives: Person-centered care (PCC) is one of the most desirable approaches for elderly with dementia. However, it has not been initiated and systematically studied in China, on which lacking of reliable and valid measurement tools is one of the key barriers. This paper aims to validate person-centered care assessment tools (P-CAT) in a Chinese context. Method: The original 13-item was translated and back translated. And 11 items were added based on literature review and expert consultation. The resulting 24-item P-CAT-C was validated among a sample of formal caregivers (n = 330) in all 34 residential care facilities in urban Xi'an, a representative city in north-western China. Chinese versions of staff-based measures of individualized care for institutionalized persons with dementia (IC) and caregiver psychological elder abuse behavior (CPEAB) scale were used to test the criterion validity. Results: Confirmatory factor analysis (CFA) showed that a three-factor 15-item solution provided adequate fit indices to the data (χ2 = 145.691, df = 81, p < 0.001, comparative fit index (CFI) = 0.926, Tucker-Lewis index (TLI) = 0.905, root mean square error of approximation (RMSEA) = 0.050). Four new items were identified and two original items were excluded. The three factors are named as (1) individualized care (6-item); (2) organizational support (6-item); and (3) environmental accessibility (3-item). The internal consistency coefficient (Cronbach's α = 0.684) is satisfactory. The interscale correlation among P-CAT-C, IC, and CPEAB showed good criterion validity. Conclusion: P-CAT-C is a culturally adapted version of the original P-CAT, which showed satisfactory reliability and validity for evaluating PCC in Chinese residential care facilities. It also provides insight to other developing countries. [ABSTRACT FROM AUTHOR]

We aim to provide an overview of clinical and demographical features and neuropathological research on frontotemporal dementia (FTD) from China over the past decade. We reviewed the demographic features, clinical presentations, and neuropathology of the FTD-spectrum disorders from the 49 cases in China published since 1998. On the basis of these findings, we retrospect the history and speculate on future progress in terms of FTD in China. We found that most published papers comprise case reports with a few retrospective studies with small sample sizes. Behavior variant FTD (bvFTD) was the most common diagnostic subtype, of which 35% were associated with amyotrophic lateral sclerosis or Parkinsonian syndrome. More than 47% patients with FTD had age onset before 65. There were no differences in age of onset and sex distribution between diagnostic subtypes. The spectrum of neuropathological diagnosis of bvFTD was frontotemporal lobe degeneration (FTLD) with tau protein or ubiquitin-immunopositive inclusions, and FTLD without intracellular inclusions. Median survival in bvFTD was 14 years. This paper provides an overview of the current status and pointers for future research directions of FTD in China. [ABSTRACT FROM AUTHOR]

The article discusses the highlights of an International Association of Gerontology and Geriatrics (IAGG) workshop on nursing homes. One of the paper presented in the workshop focused on the state of nursing homes within long-term care in Catalonia, Spain. The event also addressed the challenges posed by the increasing elderly population in China, as well as the occupancy rate in Chinese nursing homes. Another topic addressed in the workshop was chronic pain in long-term care facilities.

Background This paper describes the development and validation of the Memory Inventory for Chinese (MIC), for measuring the awareness of memory deficits in the Chinese population with Alzheimer's disease (AD). Methods A combination of qualitative and quantitative approaches was adopted. The MIC was developed with focus group discussion and pilot testing. It has a patient and a caregiver version. A consecutive series of 79 new out-patients with the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorder Association (NINCDS-ADRDA) criteria of probable and possible AD and 20 non-demented elderly subjects were recruited. Results A high internal consistency was found, with Cronbach alpha of 0.89 for the patient version and 0.90 for the caregiver version of MIC. The inter-rater reliability was satisfactory. For validity assessment, the caregiver score of the MIC correlated significantly with cognitive score of the subject as assessed by the Mini-Mental State Examination (rp = -0.37; p < 0.01). The Memory Deficit Awareness Score, calculated by subtracting the patient score from the caregiver score, correlated significantly with clinician ratings of awareness of memory impairment (rs = -0.67; p < 0.01). Conclusions The MIC appears to be a culturally appropriate and valid instrument for the measurement of awareness of memory deficits in Chinese patients with AD. Potential applications of the MIC should be further explored in other subtypes of dementia and in prospective studies. Copyright © 2006 John Wiley & Sons, Ltd. [ABSTRACT FROM AUTHOR]

There is little information on dementia research in China in the international literature. This paper is an overview of studies on dementia conducted in China. Studies on dementia research in China were identified through a literature search, as well as through consulting Chinese psychiatrists and neurologists with expertise in the field. These studies were then reviewed. Epidemiological studies on dementia in China find the rates of dementia at the lower end of rates in Caucasians. There seems to be regional variation in the ratio of vascular dementia to Alzheimer's disease in China. In addition to epidemiological studies, there are studies on the genetics, psychopathology, neurophysiology and drug treatment in dementia. There is much research activity in China in the field of dementia and further cross-cultural studies are useful to examine the cultural differences in various areas of dementia research.

Background: A rapid digital instrument is needed to facilitate community-based screening of mild cognitive impairment (MCI) and Alzheimer's disease (AD) in China. Objective: We developed a voice recognition-based cognitive assessment (Shanghai Cognitive Screening, SCS) on mobile devices and evaluated its diagnostic performance. Methods: Participants (N = 251) including healthy controls (N = 98), subjective cognitive decline (SCD, N = 42), MCI (N = 80), and mild AD (N = 31) were recruited from the memory clinic at Shanghai Sixth People's Hospital. The SCS is fully self-administered, takes about six minutes and measures the function of visual memory, language, and executive function. Participants were instructed to complete SCS tests, gold-standard neuropsychological tests and standardized structural 3T brain MRI. Results: The Cronbach's alpha was 0.910 of the overall scale, indicating high internal consistency. The SCS total score had an AUC of 0.921 to detect AD (sensitivity = 0.903, specificity = 0.945, positive predictive value = 0.700, negative predictive value = 0.986, likelihood ratio = 16.42, number needed for screening utility = 0.639), and an AUC of 0.838 to detect MCI (sensitivity = 0.793, specificity = 0.671, positive predictive value = 0.657, negative predictive value = 0.803, likelihood ratio = 2.41, number needed for screening utility = 0.944). The subtests demonstrated moderate to high correlations with the gold-standard tests from their respective cognitive domains. The SCS total score and its memory scores all correlated positively with relative volumes of the whole hippocampus and almost all subregions, after controlling for age, sex, and education. Conclusion: The SCS has good diagnostic accuracy for detecting MCI and AD dementia and has the potential to facilitate large-scale screening in the general community. [ABSTRACT FROM AUTHOR]

Objectives: More people with dementia live in low‐ and middle‐income countries (LMICs) than in high‐income countries, but best‐practice care recommendations are often based on studies from high‐income countries. We aimed to map the available evidence on dementia interventions in LMICs. Methods: We systematically mapped available evidence on interventions that aimed to improve the lives of people with dementia or mild cognitive impairment (MCI) and/or their carers in LMICs (registered on PROSPERO: CRD42018106206). We included randomised controlled trials (RCTs) published between 2008 and 2018. We searched 11 electronic academic and grey literature databases (MEDLINE, EMBASE, PsycINFO, CINAHL Plus, Global Health, World Health Organization Global Index Medicus, Virtual Health Library, Cochrane CENTRAL, Social Care Online, BASE, MODEM Toolkit) and examined the number and characteristics of RCTs according to intervention type. We used the Cochrane risk of bias 2.0 tool to assess the risk of bias. Results: We included 340 RCTs with 29,882 (median, 68) participants, published 2008–2018. Over two‐thirds of the studies were conducted in China (n = 237, 69.7%). Ten LMICs accounted for 95.9% of included RCTs. The largest category of interventions was Traditional Chinese Medicine (n = 149, 43.8%), followed by Western medicine pharmaceuticals (n = 109, 32.1%), supplements (n = 43, 12.6%), and structured therapeutic psychosocial interventions (n = 37, 10.9%). Overall risk of bias was judged to be high for 201 RCTs (59.1%), moderate for 136 (40.0%), and low for 3 (0.9%). Conclusions: Evidence‐generation on interventions for people with dementia or MCI and/or their carers in LMICs is concentrated in just a few countries, with no RCTs reported in the vast majority of LMICs. The body of evidence is skewed towards selected interventions and overall subject to high risk of bias. There is a need for a more coordinated approach to robust evidence‐generation for LMICs. Key points: While the majority of people with dementia reside in low‐ and middle‐income countries (LMICs), it is not known what types of interventions have been studied in these settings and how effective they are.We conducted the first comprehensive mapping study of interventions for people with dementia or mild cognitive impairment (MCI) and/or their carers in LMICs.This high‐level overview of dementia intervention research in LMICs identified the following gaps: dementia intervention research is highly concentrated in just a few LMICs, and skewed towards Traditional Chinese Medicine, Western pharmaceuticals, and supplements, with comparatively little evidence generated on interventions for carers.Lack of robust and locally relevant evidence on effective interventions presents a substantial challenge to designing evidence‐based treatment and care systems that help people with dementia or MCI and their carers to live better lives.

This paper reports the results of a longitudinal study carried out in urban China on the health and mental status of 200 elders 70 years of age or older and focuses on the experience of dementia. While older people and their families are aware of the phenomenon of dementia, it does not evoke the kind of dread that is common among Americans. This different response can be traced to beliefs about dementia, cultural values, and situational features of contemporary Chinese life. [ABSTRACT FROM AUTHOR]

Background: Conducting routine mild cognitive impairment (MCI) and dementia screening for older adults in the community is important, which not only can improve our understanding of these diseases but also can increase early detection and treatment. Methods: To analyze the reliability and validity of the informant AD8 and explore the cut‐off values for screening MCI and dementia in the community‐dwelling older adults, this study adopted a multi‐stage cluster sampling method to recruit 327 participants aged 60 and over in communities. The informant AD8 and Clinical Dementia Rating (CDR) scales were used to evaluate cognitive function of the subjects, and the receiver operating characteristic curves (ROC) was conducted to test the screening efficacy. Results: Among the 327 participants, 33.0% of them met the criteria of MCI, and 3.4% of them met the criteria of dementia. The area under the receiver operating characteristic curve (AUC) of the informant AD8 for screening dementia was 0.974, with a screening cut‐off of three, sensitivity of 90.9% and specificity of 89.0%. But it has a poor discriminability in MCI screening [AUC = 0.645, 95% confidence interval (CI): 0.578–0.711]. Conclusions: This study suggests that the informant AD8 is an ideal and useful tool for dementia screening in community‐dwelling older adults. However, it is less capable to distinguish older adults with MCI from those with normal cognitive function. [ABSTRACT FROM AUTHOR]

Objective: To investigate comorbidities among hospitalized patients with dementia. Method: Data were extracted from the discharge records in our hospital. Comorbidities based on ICD-10 were selected from the Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI). The distributions of these comorbidities were described in dementia inpatients and age- and sex-matched nondementia controls, as well as in inpatients with Alzheimer's disease and vascular dementia. A logistic regression model was applied to identify dementia-specific morbid conditions. Results: A total of 3355 patients with dementia were included, with a majority of 1503 (44.8%) having Alzheimer's disease, 395 (11.8%) with vascular dementia, and 441 (13.1%) with mixed dementia. The mean number of comorbidities was 3.8 in dementia patients (vs. 2.9 in controls). The most prevalent comorbidities in inpatients with dementia compared with those without dementia were cerebral vascular disease (73.0% vs. 35.9%), hypertension (62.8% vs. 56.2%), and peripheral vascular disease (53.7% vs. 31.2%). Comorbidities associated with dementia included epilepsy (OR 4.8, 95% CI 3.5–6.8), cerebral vascular disease (OR 4.1, 95% CI 3.7–4.5), depression (OR 4.0, 95% CI 3.2–5.0), uncomplicated diabetes (OR 1.5, 95% CI 1.4–1.7), peripheral vascular disease (OR 1.8, 95% CI 1.6–2.0), rheumatoid arthritis collagen vascular disease (OR 1.7, 95% CI 1.3–2.3), and anemia (OR 1.2, 95% CI 1.04–1.3). Some comorbidities suggested a protective effect against dementia. They were hypertension (OR 0.8, 95% CI 0.7–0.9), COPD (OR 0.6, 95% CI 0.5–0.6), and solid tumor without metastasis (OR 0.4, 95% CI 0.3–0.4). Vascular dementia has more cardiovascular and cerebrovascular comorbidities than Alzheimer's disease. Conclusion: Patients with dementia coexisted with more comorbidities than those without dementia. Comorbidities (esp. cardio-cerebral vascular risks) in patients with vascular dementia were more than those in patients with AD. Specifically, vascular and circulatory diseases, epilepsy, diabetes and depression increased the risk of dementia. [ABSTRACT FROM AUTHOR]

Background: People's health belief is an important factor affecting health behavior. However, there has been little use of the health belief model (HBM) in determining the pathway effect of patients' beliefs on health behavior in dementia prevention in China. The aim of our study was to evaluate the impact of dementia prevention beliefs on health promoting lifestyle among Chinese adults. Methods: A cross-sectional study was conducted on line by convenience sampling from January to March 2020. A survey about dementia prevention knowledge, health belief of dementia prevention and health-promoting lifestyle was completed by 1201 adults in China. Data was analyzed using a structural equation model with the analysis of moment program. Results: The participants were aged 40.50 ± 12.72 years. About 70.3% of participants were female. The purposed model fit the data from the study well. Perceived barriers (total effect-0.322, P < 0.01) and perceived susceptibility (total effect -0.242, P < 0.01) had negative effects on lifestyle. Self-efficacy had promoting effects on lifestyle (total effect 0.207, P < 0.01). Perceived severity had positive effects both on perceived benefits (total effect 0.137, P < 0.01) and perceived barriers (total effect 0.202, P < 0.01), which had a contradictory effect in the formation of health belief. Perceived benefits, cues to action and self-efficacy played a partial mediating role between knowledge and health behavior. The belief of changing lifestyle to reduce the risk of dementia could explain 24.5% of health behavior (P < 0.05). Conclusions: The findings indicate that in dementia prevention, dementia prevention health belief has important influences on health behavior. Community medical staff can develop targeted dementia prevention interventions based on the health belief model in the future. [ABSTRACT FROM AUTHOR]

Background: The longitudinal associations of sleep timing and time in bed (TIB) with dementia and cognitive decline in older adults are unclear. Methods: This population‐based cohort study used data from 1982 participants who were aged ≥60 years, free of dementia, and living in rural communities in western Shandong, China. At the baseline (2014) and follow‐up (2018) examinations, sleep parameters were assessed using standard questionnaires. Cognitive function was measured using the Mini‐Mental State Examination (MMSE). Dementia was diagnosed following the DSM‐IV criteria, and the NIA‐AA criteria for Alzheimer disease (AD). Data were analyzed using restricted cubic splines, Cox proportional‐hazards models, and general linear models. Results: During the mean follow‐up of 3.7 years, dementia was diagnosed in 97 participants (68 with AD). Restricted cubic spline curves showed J‐shaped associations of sleep duration, TIB, and rise time with dementia risk, and a reverse J‐shaped association with mid‐sleep time. When sleep parameters were categorized into tertiles, the multivariable‐adjusted hazard ratio (HR) of incident dementia was 1.69 (95%CI 1.01–2.83) for baseline sleep duration >8 hours (vs. 7–8 h), 2.17 (1.22–3.87) for bedtime before 9 p.m. (vs. 10 p.m. or later), and 2.00 (1.23–3.24) for mid‐sleep time before 1 a.m. (vs. 1–1.5 a.m.). Early bedtime and mid‐sleep time were significantly associated with incident AD (HR range: 2.25–2.51; p < 0.05). Among individuals who were free of dementia at follow‐up, baseline long TIB, early bedtime and mid‐sleep time, early and late rise time, and prolonged TIB and advanced bedtime and mid‐sleep time from baseline to follow‐up were associated with a greater decline in MMSE score (p < 0.05). These associations with cognitive decline were statistically evident mainly among men or participants who were aged 60–74 years. Conclusions: Long TIB and early sleep timing are associated with an increased risk of dementia, and the associations with greater cognitive decline are evident only among older people aged 60–74 years and men.

Addenbrooke's cognitive examination (ACE) is a cognitive screening tool that has developed through three stages: ACE, ACE-Revised (ACE-R), and ACE-Ⅲ. In addition, mini-Addenbrooke's Cognitive Examination (M-ACE) and ACE mobile are the additional versions that is derived from ACE-III. ACE and its related versions show better performance than Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) in detecting mild cognitive impairment in different neurological disorders. It has been translated into numerous languages, including Chinese. Through reviewing the history, validity, and comparison with other cognitive tests of Chinese versions of ACE, it aims to facilitate the clinical and scientific use, further development, improvement, and validation of Chinese versions of ACE in various neurological disorders and ultimately promote early identification and management of cognitive impairment in China.

Caregiving burden proves to be a risk factor of anxiety disorders and anxiety affection. The current study investigates how an endogenous personality dimension – neuroticism – moderates the association between caregiving burden and anxiety affection. Between 2015 and 2017, the study deployed a cross-sectional survey of 674 (response rate = 89%) older adults who were hospitalized for dementia at two hospitals. From all primary caregivers of these patients, 661 agreed to participate in the survey which yielded 661 matched dyads as the final sample. Caregiving burden, neuroticism, and anxiety affection were each measured by established assessment instruments. We employed multivariate OLS regression to test the moderator and regressor effects. We found that care burden is a significant risk factor of higher levels of anxiety affection (β =.17, p <.001), and accounts for 4.6% of the variance in anxiety. Neurotic personality is also significantly associated with a greater level of anxiety (β =.26, p <.001). Neurotic personality moderates the association between anxiety and care burden (β =.24, p <.001). Our findings suggest that social and healthcare workers should assess caregiver personality and burden as well as provide support, resources, and coping strategies to those with neurotic personality traits or high care burden in an effort to reduce anxiety among caregivers.

Background: Increased fish consumption reduces the risk of dementia. However, it is unknown whether fish consumption reduced all-cause mortality in people with dementia. The purpose of the study is to investigate the association of fish consumption with all-cause mortality in older people with dementia versus those without dementia. Methods: Using a standard method of the Geriatric Mental State, we interviewed 4165 participants aged ≥ 60 years who were randomly recruited from five provinces in China during 2007–2009 to collect the baseline data of socio-demography, disease risk factors, histories of disease, and details of dietary intakes, and diagnosed dementia (n = 406). They were followed up for vital status until 2012. Results: The cohort follow-up documented 329 deaths; 61 were in participants with dementia (55.3 per 1000 person-years) and 224 were those without dementia (22.3). In all participants, the risk of all-cause mortality was reduced with fish intake at " ≥ twice a week" (multivariate-adjusted hazard ratio 0.58, 95% CI 0.34–0.96) and at "once a week or less" (0.79, 0.53–1.18) compared to "never eat" over the past two years. In participants without baseline dementia, the corresponding HRs for all-cause mortality were 0.57 (0.33–0.98) and 0.85 (0.55–1.31), while in participants with dementia were 1.36 (0.28–6.60) and 1.05 (0.30–3.66), respectively. Conclusion: This study reveals that consumption of fish in older age reduced all-cause mortality in older people without dementia, but not in people with dementia. Fish intake should be increased in older people in general, prior to the development of dementia in the hope of preventing dementia and prolonging life. [ABSTRACT FROM AUTHOR]

Background: For community-dwelling elderly individuals without enough clinical data, it is important to develop a method to predict their dementia risk and identify risk factors for the formulation of reasonable public health policies to prevent dementia.Objective: A community elderly survey data was used to establish machine learning prediction models for dementia and analyze the risk factors.Methods: In a cluster-sample community survey of 9,387 elderly people in 5 subdistricts of Wuxi City, data on sociodemographics and neuropsychological self-rating scales for depression, anxiety, and cognition evaluation were collected. Machine learning models were developed to predict their dementia risk and identify risk factors.Results: The random forest model (AUC = 0.686) had slightly better dementia prediction performance than logistic regression model (AUC = 0.677) and neural network model (AUC = 0.664). The sociodemographic data and psychological evaluation revealed that depression (OR = 3.933, 95% CI = 2.995-5.166); anxiety (OR = 2.352, 95% CI = 1.577-3.509); multiple physical diseases (OR = 2.486, 95% CI = 1.882-3.284 for three or above); "disability, poverty or no family member" (OR = 1.859, 95% CI = 1.337-2.585) and "empty nester" (OR = 1.339, 95% CI = 1.125-1.595) in special family status; "no spouse now" (OR = 1.567, 95% CI = 1.118-2.197); age older than 80 years (OR = 1.645, 95% CI = 1.335-2.026); and female (OR = 1.214, 95% CI = 1.048-1.405) were risk factors for suspected dementia, while a higher education level (OR = 0.365, 95% CI = 0.245-0.546 for college or above) was a protective factor.Conclusion: The machine learning models using sociodemographic and psychological evaluation data from community surveys can be used as references for the prevention and control of dementia in large-scale community populations and the formulation of public health policies.

Background: Early identification of Alzheimer's disease or mild cognitive impairment can help guide direct prevention and supportive treatments, improve outcomes, and reduce medical costs. Existing advanced diagnostic tools are mostly based on neuroimaging and suffer from certain problems in cost, reliability, repeatability, accessibility, ease of use, and clinical integration. To address these problems, we developed, evaluated, and implemented an early diagnostic tool using machine learning and non-imaging factors. Methods and results: A total of 654 participants aged 65 or older from the Nursing Home in Hangzhou, China were identified. Information collected from these patients includes dementia status and 70 demographic, cognitive, socioeconomic, and clinical features. Logistic regression, support vector machine (SVM), neural network, random forest, extreme gradient boosting (XGBoost), least absolute shrinkage and selection operator (LASSO), and best subset models were trained, tuned, and internally validated using a novel double cross validation algorithm and multiple evaluation metrics. The trained models were also compared and externally validated using a separate dataset with 1,100 participants from four communities in Zhejiang Province, China. The model with the best performance was then identified and implemented online with a friendly user interface. For the nursing dataset, the top three models are the neural network (AUROC = 0.9435), XGBoost (AUROC = 0.9398), and SVM with the polynomial kernel (AUROC = 0.9213). With the community dataset, the best three models are the random forest (AUROC = 0.9259), SVM with linear kernel (AUROC = 0.9282), and SVM with polynomial kernel (AUROC = 0.9213). The F1 scores and area under the precision-recall curve showed that the SVMs, neural network, and random forest were robust on the unbalanced community dataset. Overall the SVM with the polynomial kernel was found to be the best model. The LASSO and best subset models identified 17 features most relevant to dementia prediction, mostly from cognitive test results and socioeconomic characteristics. Conclusion: Our non-imaging-based diagnostic tool can effectively predict dementia outcomes. The tool can be conveniently incorporated into clinical practice. Its online implementation allows zero barriers to its use, which enhances the disease's diagnosis, improves the quality of care, and reduces costs. [ABSTRACT FROM AUTHOR]

Introduction: To facilitate community-based dementia screening, we developed a voice recognition-based digital cognitive screener (digital cognitive screener, DCS). This proof-of-concept study aimed to investigate the reliability, validity as well as the feasibility of the DCS among communitydwelling older adults in China. Methods: Eligible participants completed demographic, clinical, and the DCS. Diagnosis of mild cognitive impairment (MCI) and dementia was made based on the Montreal Cognitive Assessment (MoCA) (MCI: MoCA < 23, dementia: MoCA < 14). Time and venue for test administration were recorded and reported. Internal consistency, test-retest reliability and inter-rater reliability were examined. Receiver operating characteristic (ROC) analyses were conducted to examine the discriminate validity of the DCS in detecting MCI and dementia. Results: A total of 103 participants completed all investigations and were included in the analysis. Administration time of the DCS was between 5.1-7.3 min. No significant difference (p > 0.05) in test scores or administration time was found between 2 assessment settings (polyclinic or community center). The DCS showed good internal consistency (Cronbach's alpha = 0.73), test-retest reliability (Pearson r = 0.69, p < 0.001) and inter-rater reliability (ICC = 0.84). Area under the curves (AUCs) of the DCS were 0.95 (0.90, 0.99) and 0.77 (0.67, 086) for dementia and MCI detection, respectively. At the optimal cut-off (7/8), the DCS showed excellent sensitivity (100%) and good specificity (80%) for dementia detection. Conclusion: The DCS is a feasible, reliable and valid digital dementia screening tool for older adults. The applicability of the DCS in a larger-scale community-based screening stratified by age and education levels warrants further investigation. [ABSTRACT FROM AUTHOR]

Aims and objectives: To explore hospital healthcare professionals' knowledge and attitudes towards dementia care in China. Background: Hospital healthcare professionals deliver most diagnosis and treatment for people with dementia in China. Literature shows that healthcare professionals' knowledge and attitudes are of great importance in providing optimum dementia care. However, there is limited research of healthcare professionals' dementia knowledge and attitudes within hospital contexts in China. Design: A cross‐sectional survey was conducted between April and December 2019. Methods: A self‐report questionnaire composed of demographics and knowledge and attitude scales related to dementia was used for doctors and registered nurses working in settings where people with dementia are cared for in eleven public tertiary hospitals in Hebei Province, China. The STROBE checklist was adhered to in this study. Results: In total, 603 healthcare professionals completed the study. The majority of respondents were registered nurses (71.3%). The overall mean knowledge score was 20.7 (SD = 2.9) out of a maximum possible score of 30. The overall mean score for attitudes was 91.3 (SD = 15.9) out of a maximum possible score of 140. Standard multiple linear regression analysis revealed that the highest level of education, the experience of searching for dementia‐related information and willingness to receive dementia training or education were significant predictors of knowledge scores. The department, the experience of working with people with dementia, length of dementia care, interest in dementia care and training type were significant predictors of attitude scores. Conclusions: Deficits in the knowledge of dementia and a low level of positive attitude were identified among the healthcare professionals who work in hospital settings where people with dementia are cared for in China. Relevance to clinical practice: Education and training in dementia care should be integrated into undergraduate nursing and medical programmes and provided for healthcare professionals after commencing employment.

Aims: To translate 25‐item Dementia Knowledge Assessment Scale into Chinese and evaluate its psychometric properties amongst Chinese healthcare providers. Background: The prevalence of dementia is increasing in China, but development of relevant training for healthcare providers is still in its infancy stage. A comprehensive, valid and reliable Chinese knowledge‐of‐dementia measure is needed to identify training needs and evaluate the effect of educational interventions. Design: A cross‐sectional survey. Methods: The Dementia Knowledge Assessment Scale was translated into Chinese following the modified Brislin's translation model. Content and face validity were established by an expert panel in dementia care and healthcare providers. A convenience sample of 290 healthcare providers in care homes and hospitals was recruited. Construct validity was evaluated through confirmatory factor analysis, concurrent validity and known groups' comparisons method. Reliability was evaluated through internal consistency reliability and 2‐week test–retest reliability. This study used the STROBE checklist for reporting. Results: The content validity index was 0.98. The confirmatory factor analysis model revealed that the four‐factor model was partly supported in the present study. The moderate correlation between Chinese version of Dementia Knowledge Assessment Scale and Alzheimer's Disease Knowledge Scale indicated acceptable concurrent validity. The mean score of the scale and subscale scores showed significant differences between health professionals and care assistants, except for the subscale of "Care Considerations." The reliability was demonstrated with Cronbach's alpha of.77 and intra‐class correlation coefficients of each subscale between.74 and.92 among 56 respondents. Conclusions: The Chinese version of Dementia Knowledge Assessment Scale demonstrated acceptable concurrent validity but marginal factorial validity and satisfactory reliability amongst Chinese healthcare providers. Therefore, applying the four‐factor structure of Chinese version scale should be considered. Relevance to clinical practice: Chinese version of Dementia Knowledge Assessment Scale can be used to understand the training needs of healthcare providers in dementia. [ABSTRACT FROM AUTHOR]

Background: The prevalence of dementia in China, particularly in rural areas, is consistently increasing; however, research on population-attributable fractions (PAFs) of risk factors for dementia is scarce. Methods: We conducted a cross-sectional survey, namely, the China Multicentre Dementia Survey (CMDS) in selected rural and urban areas from 2018 to 2020. We performed face-to-face interviews and neuropsychological and clinical assessments to reach a consensus on dementia diagnosis. Prevalence and weighted PAFs of eight modifiable risk factors (six classical: less childhood education, hearing impairment, depression, physical inactivity, diabetes, and social isolation, and two novels: olfactory decline and being unmarried) for all-cause dementia were estimated. Results: Overall, CMDS included 17,589 respondents aged ≥ 65 years, 55.6% of whom were rural residents. The age- and sex-adjusted prevalence for all-cause dementia was 9.11% (95% CI 8.96–9.26), 5.19% (5.07–5.31), and 11.98% (11.8–12.15) in the whole, urban, and rural areas of China, respectively. Further, the overall weighted PAFs of the eight potentially modifiable risk factors were 53.72% (95% CI 52.73–54.71), 50.64% (49.4–51.89), and 56.54% (55.62–57.46) in the whole, urban, and rural areas of China, respectively. The eight risk factors' prevalence differed between rural and urban areas. Lower childhood education (PAF: 13.92%) and physical inactivity (16.99%) were primary risk factors in rural and urban areas, respectively. Conclusions: The substantial urban–rural disparities in the prevalence of dementia and its risk factors exist, suggesting the requirement of resident-specific dementia-prevention strategies.

Aims: To describe a nurse‐led multicentre randomized controlled trial protocol developed to evaluate the effectiveness and cost‐effectiveness of a Chinese iSupport for Dementia program in Australia and Greater China including mainland China, Taiwan, Hong Kong and Macau. Design: A multicentre randomized controlled trial following the SPIRIT checklist. Methods: Participants in the study will be recruited from Australia and Greater China and will be randomly assigned to the intervention group or the usual care group. Interventions will include self‐learning of the iSupport program, virtual peer support and nurse program facilitator support for 6 months. Primary outcome measures will be the 12‐Item Short‐Form Health Survey. Secondary outcome measures will include: Revised Scale for Caregiving Self‐efficacy; Quality of Social Support Scale; Revised Memory and Behaviour Problem Checklist; the Quality of Life in Alzheimer's Disease‐Proxy; usages of care services; and cost‐effectiveness of the intervention. Outcomes will be measured at baseline, 6 months and 9 months from the baseline. Caregivers' experiences of the peer support will be explored. This project was funded by the National Foundation for Australia‐China Relations, Australian Government (Project ID: NFACR216). The total amount is $440,000 Australian dollars (or £ 236,231). Discussion: Approximately, 20% of people living with dementia in the world live in Australia and Greater China. Older Chinese are usually cared for by family caregivers at home due to the influence of Confucianism. However, free and online psychoeducation programs for this large cohort of caregivers are not available or accessible. The World Health Organization iSupport for Dementia is an evidence‐based online psychoeducation program for caregivers. Implementing a culturally adapted Chinese iSupport program will address this gap in supporting caregivers. Impact This study will provide research evidence on effectiveness and cost‐effectiveness of an online psychoeducation program for caregivers. Findings will inform policy and practice development.

In mainland China, as the population ages, Alzheimer's disease and related dementia (ADRD) is estimated to increase among Chinese older adults. Chinese older adults tend to hold stigmatising beliefs about ADRD that in turn affect their help-seeking behaviour and receipt of prevention and treatment. The Framework Integrating Normative Influences on Stigma provides a rationale for Chinese older adult's stigma about ADRD. Questionnaires were administered in person to 754 older adults (42% male, mean age = 69.54 years) from two urban communities in mainland China. We examined ADRD stigma and the associations with real-life exposure, knowledge of ADRD, health conditions and social networks. This study found that Chinese older adults who had good family quality, lower depression (as measured by the Center for Epidemiological Studies Depression Scale) and better cognitive health (as measured by the Montreal Cognitive Assessment) were more likely to have lower perceived stigma. Conversely, those individuals who experienced neglect and had more ADRD knowledge exhibited higher levels of perceived stigma. Social networks moderated the associations between cognitive scores and perceived stigma. This research suggested that the quality of one's social networks is essential to reduce perceived stigma among Chinese older adults. Future research should continue to explore ADRD stigma among Chinese older adults to help guide relevant interventions, services and supports for this population. [ABSTRACT FROM AUTHOR]

Background: Cognitive impairment is one of the primary sequelae affecting the quality of life of patients with Japanese encephalitis (JE). The clinical treatment is mainly focused on life support, lacking of targeted treatment strategy.Methods: A cerebrospinal fluid (CSF) proteomic profiling study was performed including 26 patients with JE in Gansu province of China from June 2017 to October 2018 and 33 other concurrent hospitalized patients who were excluded central nervous system (CNS) organic or CNS infection diseases. The clinical and proteomics data of patients with JE were undergoing combined analysis for the first time.Results: Two subtypes of JE associated with significantly different prognoses were identified. Compared to JE1, the JE2 subtype is associated with lower overall survival rate and a higher risk of cognitive impairment. The percentages of neutrophils (N%), lymphocyte (L%), and monocytes (M%) decreased in JE2 significantly.Conclusions: The differences in proteomic landscape between JE subgroups have specificity for the prognosis of cognitive impairment. The data also provided some potential target proteins for treatment of cognitive impairments caused by JE. Trial registration ChiCTR, ChiCTR2000030499.

Objectives: This study aimed to explore the stressors along with coping strategies in Chinese family caregivers whose relative with dementia had been placed into a long-term care facility. Methods: A qualitative descriptive study was conducted with 17 Chinese family caregivers of institutionalised older adults with dementia, recruited via purposeful sampling. Information regarding stressors along with coping strategies was collected through face-to-face semi-structured individual interviews. The interviews were audio-recorded, transcribed, anonymised and imported into MAXQDA 2018.2. Data were analysed with qualitative content analysis. Findings: Three categories of stressors emerged: socioeconomic pressure, hassles arising from continuing caregiving and suboptimal care provided by the facility. In particular, the family caregivers' experienced tremendous pressure of negative comments from people around since long-term care placement was traditionally viewed as unfilial in Chinese societies. Various coping strategies were adopted by Chinese family caregivers to deal with the stressors; however, they were not always adaptive. Implications: Health care authorities and professionals should recognise family caregivers' stressors after long-term care placement of a relative with dementia with the consideration of the unique socio-cultural needs. Appropriate and effective interventions should be developed and implemented to facilitate family caregivers to cope with stressful situations after long-term care placement and further to safeguard their psychosocial well-being.

Introduction: With no treatment for dementia, there is a need to identify high risk cases to focus preventive strategies, particularly in low- and middle-income countries (LMICs) where the burden of dementia is greatest. We evaluated the risk of conversion from mild cognitive ompairment (MCI) to dementia in LMICs. Methods: Medline, Embase, PsycINFO, and Scopus were searched from inception until June 30, 2020. The search was restricted to observational studies, conducted in population-based samples, with at least 1 year follow-up. There was no restriction on the definition of MCI used as long as it was clearly defined. PROSPERO registration: CRD42019130958. Results: Ten thousand six hundred forty-seven articles were screened; n=11 retained. Of the 11 studies, most were conducted in China (n = 7 studies), with only two studies from countries classified as low income. A qualitative analysis of n=11 studies showed that similar to high-income countries the conversion rate to dementia from MCI was variable (range 6.0%-44.8%; average follow-up 3.7 years [standard deviation = 1.2]). A meta-analysis of studies using Petersen criteria (n = 6 studies), found a pooled conversion rate to Alzheimer's disease (AD) of 23.8% (95% confidence interval = 15.4%-33.4%); approximately one in four people with MCI were at risk of AD in LMICs (over 3.0-5.8 years follow-up). Risk factors for conversion from MCI to dementia included demographic (e.g., age) and health (e.g., cardio-metabolic disease) variables. Conclusions: MCI is associated with high, but variable, conversion to dementia in LMICs and may be influenced by demographic and health factors. There is a notable absence of data from low-income settings and countries outside of China. This highlights the urgent need for research investment into aging and dementia in LMIC settings. Being able to identify those individuals with cognitive impairment who are at highest risk of dementia in LMICs is necessary for the development of risk reduction strategies that are contextualized to these unique settings.
