Effect of aluminum-fluoride interactions on overall cognitive function of aluminum plant workers / 环境与职业医学

Background Aluminum and fluoride are neurotoxic, and aluminum exposure alone is closely related to the overall cognitive function of operational workers. It is unclear about the effect of aluminum and fluoride interactions on cognitive function. Objective To evaluate a potential interaction effect of blood aluminum and urinary fluoride on the overall cognitive function of workers working in an aluminum plant. Methods Using cluster sampling, 230 workers in the electrolysis workshop of an aluminum group company in Shanxi Province were selected, and plasma aluminum concentrations were determined by inductively coupled plasma mass spectrometry (ICP-MS) and urinary fluoride by ion-selective electrode. The study participants were divided into a low blood aluminum group and a high blood aluminum group according to the median (M) of blood aluminum concentration, and a low urinary fluoride group and a high urinary fluoride group by a predetermined cutoff point (2.160 mg·L−1). The Montreal Cognitive Assessment-Beijing (MoCA-BJ) was used to assess overall cognitive function of the workers. Logistic regression model was used to analyze the relationship between blood aluminum, urinary fluoride, and mild cognitive impairment (MCI), including multiplicative interaction analysis and correlation analysis; R language was used to fit an additive interaction model of blood aluminum and urinary fluoride on MCI and to calculate synergy index (S), relative excess risk due to interaction (RERI), and attributable proportion due to interaction (API). Results Among the 230 operational workers, the median blood aluminum concentration (P25, P75) was 40.11 (25.16, 58.89) µg·L−1, and there were 104 cases of abnormal urinary fluoride, with an abnormality rate of 45.2%. There was a multiplicative interaction (OR=7.783, 95%CI: 1.377, 43.991) and no additive interaction (RERI=0.030, 95%CI: −0.498, 0.559; API=0.018, 95%CI: −0.279, 0.316; S=1.049, 95%CI: 0.519, 2.118) for the effect between blood aluminum and urinary fluoride on overall cognitive function of the workers. The logistic regression analysis showed that the risk of MCI was 12.105 (95%CI: 2.802, 52.287) times higher in workers with both high blood aluminum and high urinary fluoride than in those with low blood aluminum and low urinary fluoride, after adjusting for selected influencing factors. Conclusion Occupational exposure related high blood aluminum and high urinary fluoride are risk factors for cognitive dysfunction, and the coexistence of both indicators increases the risk of MCI in workers with occupational aluminum exposure, with a multiplicative interaction.

Revisión de las pruebas cognitivas breves para pacientes con sospecha de demencia / Review of brief cognitive tests for patients with suspected dementia

RESUMEN NTRODUCCIÓN: Para ser útiles, las pruebas cognitivas breves (PCB) deben ser rápidas, sensibles, fáciles de realizar y no necesitar de un gran entrenamiento para hacerlo. Las pruebas cognitivas breves comúnmente utilizadas incluyen el Mini Examen del Estado Mental (MMSE) y la Evaluación Cognitiva de Montreal (MoCA). OBJETIVO: Brindar una descripción de las PCB disponibles y sus propiedades psicométricas para la detección de la demencia. MÉTODOS: Revisión narrativa RESULTADOS: El MMSE le otorga un gran peso a la orientación, la memoria, la visuo-espacialidad y el lenguaje, y, en consecuencia, puede ser sensible a los déficits cognitivos encontrados en la demencia tipo Alzheimer. MoCA es una prueba breve más compleja que evalúa una gama más amplia de dominios cognitivos, especialmente funciones ejecutivas, proporcionando una mayor sensibilidad para detectar el deterioro cognitivo leve y otros tipos de demencia, no solo la demencia tipo Alzheimer. CONCLUSIONES: Las PCB son parte del arsenal necesario para ayudar a confirmar la sospecha de la demencia. La escolaridad tiene un impacto importante en el desempeño de las PCB y puede sesgar la interpretación de los resultados obtenidos.

ABSTRACT INTRODUCTION: To be useful, Brief Cognitive Tests (BCTs) must be fast, sensitive, easy to perform, and not require extensive training to do so. Commonly used brief cognitive tests include the Mini Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA). OBJECTIVE: To provide a description of the available BCTs and their psychometric properties for the detection of dementia. METHODS: Narrative review RESULTS: The MMSE places great weight on orientation, memory, visuospatiality, and language, and, consequently, may be sensitive to the cognitive deficits found in Alzheimer's dementia. MoCA is a more complex brief test that assesses a broader range of cognitive domains, especially executive functions, providing greater sensitivity for detecting mild cognitive impairment and other types of dementia, not just Alzheimer's dementia. CONCLUSIONS: BCTs are part of the arsenal needed to help confirm suspected dementia. Schooling has an important impact on the performance of BCTs and can bias the interpretation of the results obtained.

Correlation between lesion volume ratio and cognitive function in ischemic leukoaraiosis / 中国医师进修杂志

Objective:To investigate the relationship between the volume ratio of ischemic leukoaraiosis (LA) and cognitive level and arterial perfusion.Methods:Fifty-four patients, who was hospitalized in Dalian Central Hospital and diagnosed as LA clinically during the time of March to December in 2012, were selected to collect the information of the volume ratio of white matter disease, MoCa score and the average flow rate of carotid artery. The correlation between the volume ratio of white matter disease and MoCa score, cognitive impairment and the average flow rate of carotid artery were analyzed.Results:The volume ratio of LA lesions was negatively correlated with MOCA score ( r = -0.59, P<0.01); the volume ratio of LA lesions was negatively correlated with the mean flow rate of internal carotid artery ( r = -0.37, P<0.01). Quantity order of the area under receiver operating characteristic (ROC) curve of MoCA cognitive subgroup was as following: delayed memory (1.000)> visual space/executive function (0.970) = abstract force (0.970)> language ability (0.960)> attention (0.888). Conclusions:The larger the volume ratio of leukopathy in LA patients, the more serious the cognitive impairment, especially the cognitive impairment of impairment of memory delay, visual space/executive function, abstract ability and language ability.

Characteristics of the cognitive domains of the montreal cognitive assessment scale in the elderly from the perspective of structural equation modeling / 中华老年医学杂志

Objective:To analyzed the characteristics of the cognitive domains of the montreal cognitive assessment(MOCA)scale in cognitively impaired or normal elderly people from the perspective of structural equation modeling(SEM).Methods:There were 335 old individuals in this study, including 166 cognitively normal individuals, 130 patients with mild cognitive impairment(MCI)and 39 individuals with dementia.The average age of the individuals was 81.5±9.0.Data on the Montreal cognitive assessment(MoCA, Beijing version)were gathered.Following exploratory factor analysis and selection of latent and manifest variables, a structural equation model was established.After assessment of data from the domains of the scale in the elderly, participants were divided into a normal group and a patient group, which formed the basis of the model.Results:The KMO value of the data calculated by exploratory factor analysis was 0.762.The dimensions measured by the scale were divided into four main latent variables: memory, visuospatial execution, language ability and attention.The CMIN value of the overall model was 44.039 and the P value was 0.168.The parameters of the overall model and individual dimensions all indicated a good fit.The model showed that visuospatial execution had the largest impact on cognitive function, with a path coefficient of 0.742, and language ability had the least impact, with a path coefficient of only 0.091.As a latent variable, attention had path coefficients of 0.372 and 0.236 for memory, 1.663 and 1.102 for visuospatial execution, and 1.090 and 0.798 for language ability, respectively, for the two groups, with clear statistically significant differences between the groups(all P<0.05). Conclusions:SEM can improve researchers' overall understanding of the impacts of the individual components of the scale and their use and interpretation of the scale.

Correlation analysis of total cerebrovascular disease burden and cognitive impairment in patients with acute basal ganglia infarction / 中国神经精神疾病杂志

Objective To investigate the correlation between total burden of cerebral small vessel disease (CSVD) and cognitive impairment in patients with acute basal ganglia infarction. Methods Patients with acute basal ganglia infarction for the first time were enrolled, and the general data of the enrolled patients were collected. Patients were assessed by Montreal cognitive assessment (MoCA). Based on MoCA assessment, patients were then divided into cognitive impairment (CI) group and non-cognitive impairment (NCI) group. CSVD total load scores were conducted afterwards in order to analyze the correlation between the total load of different degrees of cerebral small vessel disease and cognitive impairment. Results A total of 178 patients were enrolled in this study: 135 in the CI group and 43 in the NCI group. There were significant differences in age (t=4.11, P=0.04) but not in high-density lipoprotein (t=2.92, P=0.09), and glycosylated hemoglobin C (t=3.02, P=0.08) between the two groups. The infarct volume was larger in the CI group (CI group: 424.72±36.55, NCI group: 227.02±34.62, t=4.022, P=0.046). There were significant differences in a sing1e lentiform nucleus (χ2=19.08, P<0.01), caudal Nucleus(χ2=9.97, P<0.01), infarction at the site of internal capsule(χ2=3.85, P=0.05), the infarct site involved lentiform nucleus, internal capsule and caudate nucleus at(χ2=4.30, P=0.04), and numbers of patients with moderate-to-severe internal carotid artery stenosis (χ2=4.14, P=0.04) as well as numbers of patients with moderate-to-severe intracranial artery stenosis (χ2=4.19, P=0.04). Similarly, there were significant differences in CSVD total burden (t=3.62, P<0.01), deep white matter hyperintensity (t=9.02, P<0.01), and cerebral microbleeds (t=5.54, P=0.02) between CI group and NCI group. The comparisons on MoCA score, visuospatial and execution, attention, language, generalization and abstraction, memory and orientation but not naming were statistically significant between the two groups. The logistic regression equation showed that CSVD total burden (OR=0.316, 95%Cl: 0.185~0.541, P<0.001), age (OR=0.924, 95%Cl: 0.884~0.967, P=0.001) and infarct volume (OR=0.924, 95%Cl: 0.884~0.967, P=0.001), (95%Cl: 1.000~1.003, P=0.047) was significantly associated with cognitive impairment in patients with acute basal ganglia infarction. Conclusion High CSVD total load score, older age and larger infarct volume may be risk factors for cognitive impairment in patients with acute basal ganglia infarction.

Associação entre classes funcionais da insuficiência cardíaca com fração de ejeção preservada e comprometimento cognitivo / Association between the functional classification of heart failure with preserved fraction ejection and cognitive impairment

INTRODUÇÃO: A insuficiência cardíaca (IC) é uma síndrome resultante de defeitos estruturais e funcionais da bomba cardíaca, mais de 80% dos pacientes são idosos, com diversas comorbidades associadas. A demência é definida por qualquer desordem onde o declínio significativo do nível prévio de cognição do paciente interfere em sua independência e funcionamento social, doméstico ou ocupacional. A relação entre o comprometimento cognitivo leve e a IC já é bem estabelecida na literatura, porém estudos recentes apontam uma possível relação da IC na patogênese e no agravo da demência. OBJETIVOS: Classificar a limitação funcional de voluntários com IC com fração de ejeção preservada (FEp) e realizar o teste Montreal Cognitive Assessment (MoCA) de memória para analisar se há associação entre as limitações funcionais da IC e o deterioramento cognitivo do paciente. MÉTODOS: Trata-se de um estudo observacional transversal, foram avaliados 27 pacientes com história de ICFEp no ambulatório de Insuficiência Cardíaca do Hospital da Universidade Luterana do Brasil. RESULTADOS: Foram avaliados 27 pacientes, com idade média de 72.4 anos, sendo 18 (66.6%) do sexo feminino, 24 (88.8%) obtiveram escore no MoCA inferior a 26, sendo a média da escala 20.4. Entre os 27 pacientes, quatro apresentavam classe funcional NYHA I, 15 NYHA II, 3 NYHA III e 5 NYHA IV. CONCLUSÃO: O estudo mostra uma tendência de pior desempenho no MoCA entre pacientes com pior classe funcional de IC (NYHA I-II: MoCA 21.4 +/- 4.9 e NYHA III-IV MoCA: 18 +/- 4.2 p:0. 0.087)

INTRODUCTION: Heart failure (HF) is a syndrome resulting from structural and functional defects of cardiac pump, more than 80% of the patients are elderly with diverse associated comorbidities. The dementia is defined by any disorder where the significant decline of the previous cognition level of the patient intervene on his independence and social, domestic or occupational functioning. The link between light cognitive impairment and HF is already well documented in literature, however recent studies point a possible relation of HF in pathogenesis and deteriorating of dementia. OBJETIVE: Rank functional limitation of volunteers with HF with preserved ejection fraction and to apply the Montreal Cognitive Assessment (MoCA) memory test to analyse if there is a association between HF functional limitations and dementia onset/worsening. METHODS: Transversal observational study, 27 patients with HF with preserved ejection fraction were assessed in Universidade Luterana do Brasil's heart failure clinic. RESULTS: Assessing 27 patients, with average age of 72.4 years (+/-7.3), being 18 (66.6%) female, we found 24 (88.8%) with MoCA score lower to 26, being the average score 20.4. Between the 27 patients, 4 had functional class NYHA I, 15 NYHA II, 3 NYHA III and 5 NYHA IV. CONCLUSION: The present study shows a tendency to lower performance in MoCA on patients with worse HF functional classification (NYHA I-II: MoCA 21.4 +/- 4.9 e NYHA III-IV MoCA: 18 +/- 4.2 p:0. 0.087)

Correlation among Three Cognitive Tools in Memory Assessment / 中国康复理论与实践

Objective:To explore the correlation and characteristics of Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) and Rivermead Behavioural Memory Test-III (RBMT-III) in evaluating memory ability of patients with brain injuries. Methods:From March, 2016 to February, 2018, 62 patients with brain injuries were evaluated with the Chinese version of MMSE, MoCA and RBMT-III. The correlation among them was analyzed. Results:There was positive correlation among the total scores of MMSE, MoCA and RBMT-III (r = 0.682 to 0.786, P < 0.001), as well as the retrospective memory (r = 0.525 to 0.610, P < 0.001) and long-term memory (r = 0.553 to 0.692, P < 0.001). There was positive correlation between RBMT-III and MMSE in short-term memory (r = 0.337, P = 0.007). The prospective memory of RBMT-III positively correlated with retrospective memory of MMSE and MoCA (r = 0.639, r = 0.585, P < 0.001), and the short-term memory of RBMT-III with long-term memory of MMSE and MoCA (r = 0.454, r = 0.534, P < 0.001). Conclusion:MMSE, MoCA and RBMT-III are consistent in evaluating retrospective memory and long-term memory for patients with brain injuries. RBMT-III and MMSE are consistent in evaluating short-term memory for patients with brain injuries. The memory scores of MMSE and MoCA are helpful to judge the event-based prospective memory in patients with brain injuries, while the scores of long-term memory are helpful to judge short-term memory.

Prognostic value of Montreal Cognitive Assessment in heart failure patients / 中华心血管病杂志

Objective@#To explore the occurrence of cognitive impairment in Chinese heart failure (HF) patients and it's impact on prognosis.@*Methods@#In this prospective observational study, a total of 990 HF patients were enrolled from 24 hospitals in China during December 2012 to November 2014. All patients were administrated with the interview-format Montreal Cognitive Assessment (MoCA), according to which they were divided into MoCA<26 (with cognitive impairment) group and MoCA≥26 (without cognitive impairment) group. Baseline data were collected and a 1-year follow up was carried out. Univariate and multivariate logistic or Cox regression were performed for 1-year outcomes.@*Results@#Cognitive impairment was evidenced in 628 patients (63.4%) and they were more likely to be older, female, and with higher proportion of New York Heart Association(NYHA) class Ⅲ-Ⅳ, chronic obstructive pulmonary disease (COPD), ischemic heart disease, while body mass index (BMI), education level, and medical insurance rate were lower (all P<0.05) as compared to patients in MoCA≥26 group. The rate of percutaneous intervention, device implantation, cardiac surgery and evidence-based medications were significantly lower in MoCA<26 group than in MoCA≥26 group (all P<0.05). During the 1-year follow up, patients in the MoCA<26 group had higher all-cause mortality (10.2%(64/628) vs. 2.2%(8/362), P<0.01), cardiovascular mortality (5.9%(37/628) vs. 0.8%(3/362), P<0.01) and major adverse cardiac and cerebrovascular events (MACCE) (9.6%(60/628) vs. 2.5%(8/362), P<0.01) than patients in the MoCA≥26 group. In univariate regression, MoCA<26 was associated with increased all-cause mortality (HR(95%CI):4.739(2.272-9.885), P<0.01), cardiovascular mortality (HR(95%CI):7.258(2.237-23.548), P=0.001) and MACCE (OR(95%CI):4.143(2.031-8.453), P<0.01). After adjustment by multivariate regression, MoCA<26 was indicated as an independent risk factor for all-cause mortality (HR(95%CI): 6.387(2.533-16.104), P<0.01), cardiovascular mortality (HR(95%CI): 10.848(2.586-45.506), P=0.001) and MACCE (OR(95%CI): 4.081(1.299-12.816), P=0.016), while not for re-hospitalization for HF (OR(95%CI):1.010(0.700-1.457), P=0.957).@*Conclusions@#Cognitive impairment is common in HF patients,and it is an independent prognostic factor for 1-year outcomes.

Association between serum non-high-density lipoprotein cholesterol and cognitive dysfunction after acute ischemic stroke: a cross-sectional study

This study aimed to explore the association between serum non-high-density lipoprotein cholesterol (non-HDL-C) and cognitive dysfunction risk in patients with acute ischemic stroke (AIS). This cross-sectional study enrolled 583 AIS patients. Biochemical markers and lipid profile were collected after admission. AIS patients were classified into high group (non-HDL-C ≥3.4 mM) and normal group (non-HDL-C <3.4 mM). Mini-Mental State Examination scale (MMSE), Montreal Cognitive Assessment scale (MoCA), Activities of Daily Living (ADL) scale, Neuropsychiatric Inventory (NPI), and Hamilton Depression scale 21 version (HAMD-21) were applied on the third day after admission. Compared with the control group, patients of the high group had higher body mass index and higher frequency of intracranial artery stenosis, and exhibited higher levels of non-HDL-C, total cholesterol, triglycerides, low-density lipoprotein cholesterol, homocysteine, fasting blood glucose, and glycosylated hemoglobin (HbA1c), and lower levels of high-density lipoprotein cholesterol (all P<0.05). Compared with the control group, patients of the high group had significantly lower MMSE and MoCA scores (MMSE: 26.01±4.17 vs 23.12±4.73, P<0.001; MoCA: 22.28±5.28 vs 20.25±5.87, P<0.001) and higher scores on the NPI and HAMD-21 (both P<0.001). MMSE (r=-0.306, P<0.001) and MoCA scores (r=-0.251, P<0.001) were negatively associated with non-HDL-C level. Multivariate regression analysis revealed that non-HDL-C level (OR=1.361, 95%CI: 1.059-1.729, P=0.016) was independently associated with the presence of cognitive dysfunction after adjusting for confounding factors. High serum non-HDL-C level might significantly increase the risk of cognitive dysfunction after AIS.

OBJECTIVE: To investigate the clinical effect of electroacupuncture at Baihui (GV20) and Shuigou (GV26) points in the treatment of brain injury in patients with sepsis-associated encephalopathy(SAE). METHODS: A total of 70 patients with SAE were randomly divided into control group and treatment group, with 35 patients in each group. The patients in the control group were given routine western medicine treatment, including anti-infective therapy, nerve nutrition, and mechanical ventilation, and those in the treatment group were given electroacupuncture at GV20 and GV26 in addition to the treatment in the control group. The course of treatment was 1 week for both groups. Serum levels of C-reactive protein (CRP), interleukin-6 (IL-6), and neuron-specific enolase (NSE) were measured for both groups, the Montreal Cognitive Assessment (MoCA) scale was used to assess the change in cognitive function, and Glasgow Coma Scale (GCS) score was determined before and after treatment and was used to evaluate treatment outcome after treatment. RESULTS: Both groups had significant reductions in the serum levels of CRP, IL-6, and NSE after 24 h and one week of treatment (P<0.05), and compared with the control group, the treatment group had significant reductions in the levels of CRP, IL-6 and NSE after treatment (P<0.05). The treatment group had significant increases in the total score of MoCA and the scores of all dimensions except attention after one week of treatment (P<0.05), and the treatment group had significantly higher scores than the control group after treatment (P<0.05). Both groups had a significant increase in GCS score after one week of treatment (P<0.05), and the treatment group had a significantly higher GCS score than the control group after treatment (P<0.05). The treatment group had a significantly higher total effective rate than the control group ［88.6% (31/35) vs 57.1% (20/35), P<0.05］. CONCLUSION: Electroacupuncture at GV20 and GV26 can effectively improve brain injury and effective rate in SAE patients.

Association between socio-demographic profile and severity of cognitive impairment in elder patients presenting with new onset of psychiatric symptoms: a cross sectional study

Background: Cognitive impairment in the elderly is a common condition and, in most instances, primary care providers are the first point of contact for a patient and family. This study was aimed to find out the association between socio-demographic profile and severity of cognitive impairment in elder patients presenting with new onset of psychiatric symptoms.Methods: A cross sectional study was done among elder subjects (≥60 years of age) presented with new onset of psychiatric symptoms during one year period. A structured questionnaire was used to assess the socio-demographic details such as age, sex, education, occupation, socio-economic status and marital status. Mini International Neuropsychiatric interview and Montreal Cognitive Assessment scale were used for psychiatric diagnosis and severity of cognitive impairment grading, respectively. Association between socio-demographic data and cognitive impairment was statistically analyzed.Results: Among the 67 subjects included in the study, 76.2% had cognitive impairment. Majority of the subjects were females (56.7%) in the age group of 66-70 years. The association between cognitive impairment and sex (p=0.006), education (p=0.002) and occupation (p=0.015) were significant. But no significant association between cognitive impairment and marital status (p=0.0137) or socioeconomic status (p=0.400) was evidenced.Conclusions: Females in the age group of 66-70 years were more prevalent to cognitive impairment. The association between sex, education, occupation and severity of cognitive impairment was significant. No significant association between severity of cognitive impairment score and marital status or socioeconomic status was found.

Objetivos: Evaluar las alteraciones de diferentes funciones neurocognitivas de los pacientes con infección por el virusde inmunodeficienciahumana, en una institución prestadora de servicios de salud de la cuidad de Ibagué - Colombia. Método: Se utilizó la Evaluación Cognitiva Montreal (MoCA), la cual fue diseñada como un instrumento ágil para determinar alteraciones cognitivas leves. La población objeto de estudio la constituyeron 44 pacientes portadores de virus de inmunodeficiencia humana, seleccionados dentro de un marco de muestreo no-probabilístico con muestra intencional o de conveniencia, entre los 14 y 75 años de edad. Resultados: Mayor deterioro neurocognitivo en los pacientes diagnosticados con virus de inmunodeficiencia humana de mayor edad; datos epidemiológicos indican que la edad más avanzada se asocia a una mayor prevalencia de desorden neurocognitivo asociado al virus de inmunodeficiencia humana. Conclusiones: El estudio de los mecanismos del deterioro neurocognitivo en pacientes con virus de inmunodeficiencia humana se hace cada vez más relevante, porque cada día aumenta su esperanza de vida, pero a su vez genera complicaciones con mayor predominio de la comorbilidad médica, psiquiátrica y neurológica(AU)

Introduction: The Human Immunodeficiency Virus, known for its impact on the immune system, causes progressive neurologic manifestations with cognitive impairment, disrupting attention functions, memory, language, execution and processing of information. The latter negatively interferes in social, work and family life of the patient. Objectives: To evaluate alterations in varied neurocognitive functions on patients with Human Immunodeficiency Virusinfection, at a health institution in Ibague, Colombia. Method: The Montreal Cognitive Assessment (MoCA) was used. It was designed as a tool to determine mild cognitive alterations. The study population was made up of 44 carriers of Human Immunodeficiency Virus who were selected within a framework of non-probabilistic sampling and with purposive sample or convenience, between 14 and 75 years old. Results: Greater neurocognitive impairment in patients diagnosed with Human Immunodeficiency Virus in legal age; someepidemiological data indicate that the older age is associated with a higher prevalence of neurocognitive disorder associated with Human Immunodeficiency Virus. Conclusions: The study of the neurocognitive impairment mechanisms in patients with Human Immunodeficiency Virus becomes increasingly more relevant, as their life expectancy increases daily. On the other hand, it causes complications with greater prevalence of medical psychiatric and neurological comorbidity(AU)

Montreal Cognitive Assessment scale in patients with Parkinson Disease with normal scores in the Mini-Mental State Examination / Detecção de comprometimento cognitivo de acordo com a escala Montreal Cognitive Assessment em pacientes com doença de Parkinson idiopática com cognição normal de acordo com o escore no miniexame do estado mental

ABSTRACT: Several screening tests have been used for cognitive evaluation in Parkinson's disease (PD). Objective: To evaluate the usefulness of the Montreal Cognitive Assessment (MoCA) in patients with Parkinson's disease and no cognitive impairment complaints. Methods: A total of 40 PD patients with no complaints of cognitive problems were included. Patients were selected using the Mini-Mental State Examination (MMSE) and the MoCA was then administered. Results: 80% of patients exhibited Mild Cognitive Impairment (MCI) according to the MoCA. Statistically significant differences in visuospatial, attention and delayed recall functions were evident between the normal and abnormal MoCA groups. Conclusion: The study results suggest that MoCA may be a good screening test in patients with PD who do not present cognitive complaints.

RESUMO: Vários testes de triagem foram utilizados para avaliação cognitiva na doença de Parkinson (DP). Objetivo: Avaliar a utilidade da Avaliação Cognitiva de Montreal (MoCA) em pacientes com doença de Parkinson sem queixa de comprometimento cognitivo. Métodos: Um total de 40 pacientes com TP sem queixas de problemas cognitivos foram admitidos e com o Estado de Exame do Estado Mental Mini (MEEM) foram selecionados e receberam o MoCA. Resultados: 80% apresentaram dados de Comprometimento Cognitivo Leve (ICM) segundo o MoCA, sendo as funções visoespaciais, atenção e memória atrasada aquelas que apresentaram diferenças estatisticamente significantes entre os grupos MoCA normal e anormal. Conclusão: Este estudo sugere que o MoCA pode ser um bom teste de triagem em pacientes com DP que não apresentam queixas cognitivas.

Diabetes control, dyslipidemia, hsCRP and mild cognitive impairment in non-elderly people with type 2 diabetes mellitus

Background: Mild Cognitive Impairment (MCI) a transitional stage between normal aging and dementia has been observed more in people with diabetes when compared with general population. The risk factors for MCI in type 2 diabetes mellitus (T2DM) have been defined in elderly patients and aging may itself contribute to declining in cognitive functions. As the large number people with T2DM are under 60years, the prevalence of MCI and factors contributing to it are not much studied. So, this study aimed to find out the factors contributing to MCI in non-elderly T2DM patients.Methods: In this cross-sectional study, 257 patients with T2DM underwent cognitive assessment by Montreal cognitive assessment test and the cognitive levels were correlated with their glycosylated hemoglobin, lipid profile, and highly sensitive C-reactive protein (hsCRP).Results: The prevalence of mild cognitive impairment (MCI) was 64.2%.  MCI significantly correlated with duration of diabetes, socioeconomic status, HbA1c, serum triglycerides, low-density lipoprotein, very low-density lipoprotein and hsCRP levels. The factors that were statistically insignificant were body mass index and high-density lipoprotein levels.Conclusions: Cognitive impairment is seen even in non-elderly T2DM patients. It should be considered along with the other complications of diabetes and individuals with T2DM should be screened for cognitive impairment to prevent progression to dementia.

The effect of vitamin D on cognitive functions in young female patients: a prospective controlled study using the Montreal Cognitive Assessment / O efeito da vitamina D nas funções cognitivas em pacientes jovens do sexo feminino: um estudo prospectivo controlado usando a avaliação cognitiva de Montreal

ABSTRACT Aim: Our aim was to determine whether there is a relationship between vitamin D [25(OH)D] and cognitive functioning in women with low 25(OH)D levels. Methods: Ninety female patients, 25-45 years of age, who attended our outpatient clinic and had 25(OH)D levels < 30 ng/mL, were included. The Montreal Cognitive Assessment (MoCA) scale was used to determine cognitive functioning; the scale is divided into seven subgroups. Patients were divided into three subgroups according to their 25(OH)D levels. After a three-month period of 25(OH) D replacement, the patients underwent a re-evaluation using the MoCA scale. Results: The total MoCA score before treatment was significantly different from the score after treatment (p < 0.05). Language and delayed recall functions were significantly different before and after treatment (p < 0.05). Conclusion: Vitamin D levels were related to cognitive functioning in our study group.

RESUMO Objetivo: Nosso objetivo foi determinar se existe uma relação entre a vitamina D [25(OH)D] e o funcionamento cognitivo em mulheres com baixos níveis de 25(OH)D. Métodos: Noventa pacientes do sexo feminino (25-45 anos de idade) que se apresentaram ao nosso ambulatório e tinham níveis de 25(OH)D <30 ng/mL foram incluídas. A escala de avaliação cognitiva de Montreal (MoCA) foi usada para determinar o funcionamento cognitivo; a escala é dividida em sete subgrupos. As pacientes foram divididas em três subgrupos de acordo com seus níveis de 25(OH)D. Após um período de três meses de reposição de 25(OH)D, as pacientes foram submetidas a uma reavaliação de acordo com a escala MoCA. Resultados: O escore total da MoCA antes do tratamento foi significativamente diferente do escore após o tratamento (p <0,05). As funções de idioma e recordação atrasada foram mais significativamente diferentes entre antes e depois do tratamento (p <0,05). Conclusão: O nível de vitamina D foi relacionado ao funcionamento cognitivo em nosso grupo de estudo.

acupuncture method for mild cognitive impairment: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the clinical efficacy of acupuncture method for mild cognitive impairment in the elderly.@*METHODS@#A total of 96 patients were randomly divided into an observation group, a control group and a waiting group, 32 cases in each group. The patients in the observation group were treated with acupuncture at Baihui (GV 20), Shenting (GV 24), Yintang (GV 29) and Sishencong (EX-HN 1), etc, while the patients in the control group were treated with nonpenetrating sham acupuncture at the same acupoints as the observation group. The treatment was given once every other day, three times a week for 8 weeks. The patients in the waiting group only received health guidance for 8 weeks. Montreal cognitive assessment scale (MoCA) and mini-mental state examination (MMSE) were used before and after 8-week treatment in all three groups. The observation group and the control group were followed up for 2 months and evaluated with MoCA and MMSE.@*RESULTS@#The MoCA scores in the observation group after treatment and during follow-up were higher than before treatment (0.05). The MoCA scores in the control group after treatment and during follow-up were higher than before treatment (0.05). The difference before and after treatment in the observation group was higher than the control group and waiting group (0.05). The MMSE scores after treatment and during follow-up were higher than before treatment in the control group (0.05). The difference before and after treatment the observation group and control group was not significant (>0.05), and those in the two groups were higher than the waiting group (<0.01). The difference between follow-up and before treatment in the observation group was higher than the control group (<0.01), and the difference between follow-up and after treatment was lower than the control group (<0.01).@*CONCLUSION@# acupuncture method could improve cognitive impairment in elderly patients with mild cognitive impairment.

Characteristics and Related Factors of Cognitive Impairment for Severe Traumatic Brain Injury / 中国康复理论与实践

Objective:To investigate the characteristics of cognitive impairment of patients with severe traumatic brain injury (TBI) and to analyze the related factors. Method:From September, 2015 to September, 2017, 94 patients surviving from severe TBI were assessed with Montreal Cognitive Assessment (MoCA), and their baseline data were recorded in detail. Results:The scores were lower in the recall, abstraction, verbal fluency, visual executive and attention of MoCA, and higher in naming, digit span, orientation and calculation. The scores in total, attention, abstraction and recall were lower in patients with frontal lobe injury than those with basal ganglion injury. The scores in total, naming, abstraction and recall were lower in patients with frontal-temporal-parietal lobes injury than those with basal ganglion injury. Multivariate regression showed that the time of coma and the location of injury were the related factors to the total score of MoCA (P < 0.05). Conclusion:Cognitive impairment after TBI demostrates commonly in many aspects, which are related with the time of coma and the area of injury.
