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.
目的:探讨被误诊为功能性精神障碍的麻痹性痴呆患者的临床特点和诊治要点。方法:回顾性分析10例被误诊为功能性精神障碍的麻痹性痴呆患者的临床资料。结果:被误诊为功能性精神障碍的麻痹性痴呆均以精神症状为首发，多表现为精神病性症状、类躁狂、抑郁、类神经症、人格的改变及进行性痴呆等不典型症状群，本研究显示误诊率高达71.4%，误诊例次率以精神分裂症最高（47.3%），其次为躁狂症或躁狂状态（37.5%）。抗精神病药物能有效改善精神症状，青霉素驱梅能阻止病情进展使病情得到缓解，两者缺一不可。结论:被误诊为功能性精神障碍的麻痹性痴呆均以精神症状为首发且症状不典型而易被误诊，早期鉴别诊断十分重要，抗精神病药物和青霉素治疗可以有效控制症状。
【摘要】 目的 探讨3分法画钟测验（clock drawing test，CDT）对阿尔茨海默病患者（Alzheimer disease，AD）与血管性痴呆患者（vascular dementia，VD）的鉴别作用。 方法 收集四川大学华西医院神经内科门诊及住院部2009年9月-2010年6月就诊的认知功能障碍患者150例，进行病史采集及神经心理测试量表，筛选出AD患者57例及VD患者43例，共计纳入100例。在两者间进行CDT，分析两者间CDT有无差别、CDT与中文版简易智能量表（Chinese version of the mini-mental state examination，MMSE）及临床痴呆评定量表（clinical dementia rating scale，CDR）的相关性。 结果 AD患者及VD患者间CDT差异无统计学意义（Pgt;0.05）；CDT与MMSE及CDR有相关性，Spearman相关系数分别为0.573和-0.542（Plt;0.001）。 结论 3分法画钟测验无法准确区分AD和VD，但对粗略判断AD及VD程度可能有一定效果。【Abstract】 Objective To investigate the differential function of the three-point scoring system for the clock drawing test (CDT) between Alzheimer’s disease (AD) and vascular dementia (VD). Methods We analyzed the clinical data of 150 patients with cognitive impairment treated in the neurology and inpatient departments of our hospital from September 2009 to July 2010. Medical history of the subjects were collected. Through the assessment by neurological and psychological rating scale, we picked out 57 patients with AD and 43 with VD and tested them with CDT. The difference of CDT results between the two groups, and the correlation of CDT with Chinese version of the mini-mental state examination (MMSE) and clinical dementia rating scale (CDR) were analyzed. Results There was no statistical difference of CDT results between AD and VD patients (Pgt;0.005). CDT had a correlations with MMSE and CDR, the Spearman correlation coefficient being 0.573 and -0.542 respectively (Plt;0.001). Conclusion The three-point scoring system for the clock drawing test cannot differentiate exactly between Alzheimer Disease and Vascular Dementia, but it can make a gross judgment of the degree of AD and VD.
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.
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.
ObjectiveTo systematically review the efficacy and safety of non-pharmacological interventions for sleep disturbance in dementia, and to provide evidence for clinical practice.MethodsDatabases including CNKI, WanFang Data, VIP, PubMed, EMbase and The Cochrane Library were searched to collect randomized controlled trials (RCTs) on non-pharmacological interventions for sleep disturbance in dementia from inception to May 2020. Two reviewers independently screened literature, extracted data, and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 9 RCTs were included, involving 720 patients. Light therapy was the most commonly used treatment, followed by special activity and sleep education program. The results of meta-analysis showed that compared with the control intervention, light therapy could improve sleep efficiency (MD=2.21, 95%CI 1.09 to 3.33, P=0.0001) and the night-time sleep (MD=14.27, 95%CI 5.01 to 23.53, P=0.003) of patients with dementia in the community and nursing institutions, special activity could increase the night-time sleep (MD=29.74, 95%CI 20.44 to 39.04, P<0.00001), and sleep education program could also improve sleep efficiency (MD=6.19, 95%CI 5.22 to 7.16, P<0.00001) and night-time sleep (MD=33.95, 95%CI 25.40 to 42.50, P<0.00001). In addition, it was superior to obtain 120 or 60 minutes of light exposure than 30 minutes to improve the quality of sleep (RR=−2.62, 95%CI −3.56 to −1.68, P<0.001) and reduce daytime sleep (RR=−4.75, 95%CI −5.71 to −3.42, P<0.001). However, there was significant difference in incidence of adverse reactions between groups of 120 minutes and 30 minutes of light exposure (RR=2.57, 95%CI 1.44 to 4.58, P=0.001).ConclusionsThe current evidence shows that non-pharmacological intervention can improve sleep efficiency and night-time sleep in patients with dementia. Due to limited quantity and quality of the included studies, more high quality studies are required to verify above 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.
【摘要】 目的 通过比较遗忘型轻度认知障碍（amnestic mild cognitive impairment，aMCI）和血管性认知障碍非痴呆型（vascular cognitive impairment-no dementia，VCI-ND）患者及正常老年人群在简易智能精神状态检查量表（mini mental state examination，MMSE）、听觉词语学习测验（auditory verbal learning test，AVLT）、画钟试验（clock drawing test，CDT）及临床痴呆评定量表（clinical dementia rating scales，CDR）中的表现，进一步分析aMCI和VCI-ND在认知损害方面的不同特点。 方法 选取首都医科大学宣武医院神经内科门诊收治aMCI患者23例及VCI-ND患者27例（CDR＝0.5分），同时选取40名正常老年人（CDR=0分）作为对照组。每位受试者均进行MMSE、AVLT、CDT及CDR等神经心理学量表测查，分析以上3组被试各项神经心理学测查得分之间的差异。 结果 各组受试者的年龄、性别及受教育程度差异无统计学意义（Pgt;0.05），具有可比性。aMCI和VCI-ND组在MMSE、CDT、即刻记忆、延迟记忆及延迟再认检测中的平均值均低于对照组，且差异均具有统计学意义（Plt;0.05）。aMCI和VCI-ND两组除延迟再认检测外，其余各项测查的平均分均无统计学意义（Pgt;0.05）。在延迟再认检测中，aMCI组（6.65±4.00）较VCI-ND组（8.67±2.76）再认词语数量少，两组延迟再认的得分均低于对照组（12.83±1.77），差异有统计学意义（Plt;0.05）。 结论 aMCI和VCI-ND在记忆力、执行能力和信息处理能力方面较正常老年人均有所损害。由于aMCI和VCI-ND不同的病理改变，导致患者存在不同类型的记忆储存和提取机制。【Abstract】 Objective To investigate the different patterns of cognitive impairment in patients with amnestic mild cognitive impairment (amci), vascular cognitive impairment-no dementia (VCI-ND) and normal elder people. Methods A total of 23 patients with aMCI and 27 patients with VCI-ND (CDR＝0.5) and another 40 healthy elder people (CDR=0) were selected. Each individual underwent the neuropsychological tests, including mini mental state examination (MMSE), auditory verbal learning test (AVLT), clock drawing test (CDT), clinical dementia rating scales (CDR) and hamilton rating scale for depression (HAMD). The differences between the three groups were analyzed. Results The differences in age, sexes, and the education background among the three groups were not significant (Pgt;0.05) which meant comparability. The mean scores of MMSE, CDT, instant memory and delayed awareness in aMCI and VIC-ND group were much lower than that in the control group (Plt;0.05). The differences in all the test items except for delayed awareness between aMCI group and VCI-ND groups were not significant (Pgt;0.05). However, in the recall recognition test, these three groups had significant differences: the score in patients with aMCI (6.65±4.00) was much lower than that in patients with VCI-ND (8.67±2.76; Plt;0.05), and the scores of the two groups were both lower than that in the normal aging group (12.83±1.77; Plt;0.05). Conclusion Compared with normal elder people, the cognition of aMCI and VCI-ND patients is impaired severely. The memory tests suggeste that compared with aMCI patients, VCI-ND patients may have different neuropathological changes leading to different mechanism of memory encoding and retrieval.
