ObjectiveTo investigate the clinical research development of dementia in the UK Biobank database in SCIE and PubMed. MethodsThe literatures of dementia in the UK Biobank database published in SCIE and PubMed from January 1, 2018 to November 30, 2022 were searched, and the number of articles, publishing institutions, journals, citations, authors and keywords were statistically analyzed. ResultsA total of 279 papers were included, and the number of papers presented an annual growth trend. The United Kingdom has the largest number of publications, the United States journals have the greatest influence, and China has the third largest number of publications. Springer Nature from Germany published the most papers, with the largest number of 47 papers. Among the authors, Yu JT from China published the most, with 11 articles, and the most major keyword in the research content is Alzheimer. ConclusionThe literatures of dementia in the UK Biobank-related field included in SCIE and PubMed databases show an increasing trend year by year, mainly in English, and the core author group has not yet formed. The papers published by Chinese scholars are concentrated in 2020-2022, and there are few transnational cooperative papers.
Post-stroke cognitive impairment (PSCI) is the most common dysfunction after stroke, which seriously affects patients’ quality of life and survival time. To strengthen the management and prevention of PSCI, the European Stroke Organization and the European Academy of Neurology jointly developed the guidelines for PSCI in 2021. This paper introduces the background, compilation method and structure, management suggestions and expert consensus of PSCI, the next research direction, etc. Compared with the current prevention and treatment measures of PSCI in China, it aims to provide methodological reference for Chinese scholars to develope PSCI guidelines and reference evidence for clinical prevention and treatment of PSCI.
Dementia is a neurodegenerative disease closely related to brain network dysfunction. In this study, we assessed the interdependence between brain regions in patients with early-stage dementia based on phase-lock values, and constructed a functional brain network, selecting network feature parameters for metrics based on complex network analysis methods. At the same time, the entropy information characterizing the EEG signals in time domain, frequency domain and time-frequency domain, as well as the nonlinear dynamics features such as Hjorth and Hurst indexes were extracted, respectively. Based on the statistical analysis, the feature parameters with significant differences between different conditions were screened to construct feature vectors, and finally multiple machine learning algorithms were used to realize the recognition of early categories of dementia patients. The results showed that the fusion of multiple features performed well in the categorization of Alzheimer’s disease, frontotemporal lobe dementia and healthy controls, especially in the identification of Alzheimer’s disease and healthy controls, the accuracy of β-band reached 98%, which showed its effectiveness. This study provides new ideas for the early diagnosis of dementia and computer-assisted diagnostic methods.

ObjectiveTo systematically review the data of peripheral inflammatory markers in patients with Alzheimer’s disease (AD) and vascular dementia (VaD) to further indicate pathogenesis and antidiastole.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on peripheral inflammatory markers in patients with AD and VaD from inception to July 2020. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies, and meta-analysis was performed by using Stata 15.1SE software.ResultsA total of 30 studies involving 2 377 patients were included. The results of meta-analysis showed that the IL-6 level was higher in VaD group than that in AD group (SMD=−0.477, 95%CI −0.944 to −0.009, P=0.046). However, there were no statistical difference in peripheral IL-1β (SMD=−0.034, 95%CI −0.325 to 0.257, P=0.818), TNF-α (SMD=0.409, 95%CI −0.152 to 0.970, P=0.153) or CRP (SMD=0.277, 95%CI −0.228 to 0.782, P=0.282) levels.ConclusionsThese findings suggest that IL-6 may be sensitive markers to distinguish AD from VaD. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the conclusions.
Vascular dementia is one of the most common types of dementia in China. How to better prevent and treat vascular dementia is still an unresolved problem, and the risk predictor of vascular dementia may help provide clinical targeted prevention measures to intervene in the development process of vascular dementia early. This article reviews the current research status of vascular dementia predictors from four aspects: blood markers, predictors based on disease characteristics, predictors based on assessment tools and neuropsychological tests, and predictors based on activity dysfunction. It aims to provide a basis for establishing a risk prediction model for patients with vascular dementia suitable for China’s conditions in the future.
Objective To systematically review the effect of vitamin D (VitD) supplementation on cognitive function in people with cognitive impairment and non-cognitive disorders. MethodsThe PubMed, Web of Science, Cochrane Library, EMbase, CBM, CNKI, WanFang Data and VIP databases were searched to collect randomized controlled trials (RCTs) about the effect of VitD supplementation on cognitive function of patients with cognitive impairment or non-cognitive disorders from inception to March, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software. Results A total of 19 articles including 8 684 cases were included. The results of meta-analysis showed that mini-mental state examination (MMSE) score (MD=1.70, 95%CI 1.20 to 2.21, P<0.01), Montreal cognitive assessment (MoCA) score (MD=1.51, 95%CI 1.00 to 2.02, P<0.01), Wechsler Adult Intelligence Scale-Revised (WAIS-RC) score (MD=9.12, 95%CI 7.77 to 10.47, P<0.01) and working memory (SMD=1.87, 95%CI 1.07 to 2.67, P<0.01) in the VitD group of patients with cognitive impairment were all better than those in the control group. However, the overall cognitive function and working memory of the non-cognitive impairment population were not significantly different compared with the control group. In terms of language fluency and language memory, there was no significant difference between the VitD group and the control group. In terms of the executive functions, at the intervention time of> 6 months, the VitD and control groups were statistically significant (SMD=0.15, 95%CI 0.01 to 0.28, P=0.03). Conclusion Current evidence suggests that VitD supplementation can effectively improve the overall cognitive function and working memory of patients with cognitive impairment, and has a positive effect on executive function at an intervention time of >6 months. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusion.

Objective To analyze the characteristic and temporal trend in mortality and disease burden of Alzheimer’s disease (AD) and other forms of dementia in Guangzhou from 2008 to 2019, and estimate the disease burden attributable to smoking to provide evidence for promoting local health policy of prevention and intervention of dementia. Methods Based on the data of Guangzhou surveillance point of the National Mortality Surveillance System (NMSS), the crude mortality, standardized mortality, years of life lost (YLL) of AD and other dementia were calculated. The indirect method was used to estimate years lived with disability (YLD) and disability-adjusted life years (DALY).The distribution and changing trends of the index rates were compared from 2008 to 2019 using Joinpoint Regression Program. Based on the data of Guangzhou Chronic Disease and Risk Factors Monitoring System in 2013, the indexes of disease burden of AD and other forms of dementia attributable to smoking in 2018 was calculated. Results The standardized mortality rate, YLL rate, YLD rate and DALY rate of AD and other forms of dementia in Guangzhou increased from 0.45/100 000, 0.05‰, 0.02‰ and 0.07 ‰ in 2008 to 1.28/100 000, 0.15‰, 0.07‰ and 0.22‰ in 2019, respectively. The average annual changing trend was statistically significant (AAPC=11.30%, 13.09%, 13.09%, 13.09%, P<0.001）. In most years, the mortality and disease burden of women were higher than those of men, but men had higher growing trend than women in standardized mortality rate, YLL rate, YLD rate and DALY rate from 2008 to 2019, with a slower growing speed after the year 2012.The disease burden of dementia attributable to smoking in men was significantly higher than that in women. Conclusion The mortality and disease burden of AD and other forms of dementia in Guangzhou have dramatically increased over the past twelve years. Intervention against modifiable factors such as smoking, and prevention and screening for dementia in key populations should be strengthened. Support policies for dementia care management should be adopted to reduce the disease burden caused by premature death and disability.
ObjectiveTo systematically review the methodological quality of evidence-based guidelines on non-pharmacology management of behavioral and psychological symptoms of dementia, so as to provide references for taking caring for the dementia with behavioral and psychological symptoms. MethodsGuidelines concerning non-pharmacology treatment of behavioral and psychological symptoms were searched from websites of guideline development, websites of medical association and literature databases from inception to May 31st 2016. The methodological quality of included guidelines were evaluated according to the AGREE Ⅱ instrument, and the differences and similarities between recommendations of included guidelines were compared. ResultsA total of 544 literatures were identified and 6 of them were included. All the included guidelines were from abroad. The average scores of guidelines in six domains of AGREE Ⅱ were:scope and purpose 88.89%, stakeholder involvement 65.74%, rigor of development 63.72%, clarity of presentations 86.11%, applicability 50.69%, and independence 37.50%. The overall qualities of the included guidelines were grade B. The recommendations of the included guidelines were almost consistent. Recommended non-pharmacology management of behavioral and psychological symptoms of dementia included leisure and recreation activity, reminiscence therapy, behavioral therapy, training of caregivers, physical environment modification, animal-assisted therapy, massage, physical activity and patient-centered approach. ConclusionThe overall quality of included guidelines is relatively high. More efforts are needed to improve the applicability and independence of guidelines. There is still no local guideline concerning non-pharmacology recommendations on behavioral and psychological symptoms of dementia in China. It is suggested to develop guideline that is suitable for Chinese condition as soon as possible.
