Impact of non-valvular atrial fibrillation on global cognitive function and executive function / 中华心血管病杂志

Objective: To explore the impact of non-valvular atrial fibrillation (AF) on the global cognitive function and executive function of patients without dementia, and to observe the differences between different types of AF. Methods: This research is a prospective and cross-sectional study. Non-dementia patients admitted to the department of neurology in the third people's hospital of Chengdu from July 2018 to July 2019 were included. Patients with non-valvular AF were included in the AF group and those with sinus rhythm were included in the control group. General clinical data and compared global cognitive function (mini-mental state examination (MMSE) and montreal cognitive assessment (MOCA)) and executive function (shape trails test (STT) and stroop color and word test (SCWT)) data were obtained and compared between 2 groups, and between different AF type groups. Results: A total of 386 participants were included, including 203 in AF group (52.6%), age was 68 (63, 71) years old, 119 were male (58.6%) and 183 in control group, age was 68 (63, 71) years old, 101 were male (55.2%). MMSE(28 (27, 29)) and MOCA (25 (22, 26)) scores were lower in AF group than those in control group (P<0.05), while STT-A time (84 (64, 140) s), STT-B time (248 (184, 351) s), STT time difference((159 (106, 245) s), SCWT-A time (50 (50, 50) s), SCWT-B time (55 (46, 63) s), SCWT-C time (100 (86, 120) s) and SCWT time interference (46 (34, 65) s) were higher than those in control group (P<0.05). Moreover, there was no difference in above indexes between paroxysmal AF and non-paroxysmal AF. Conclusion: The global cognitive function and executive function of patients with non-valvular AF are both decreased, while there is no obvious difference of the global cognitive function and executive function between paroxysmal AF and non-paroxysmal AF patients.

Estudio exploratorio para la validación de la Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) en la población con esclerosis múltiple remitente recurrente del Hospital San Juan de Dios en Santiago de Chile / Exploratory study for the validation of the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS) in the population with recurrent remitting multiple sclerosis of the San Juan de Dios Hospital in Santiago, Chile

La evaluación cognitiva en personas adultas con esclerosis múltiple (EM) es un área fundamental a tener en cuenta en el proceso de intervención, debido a la alta prevalencia de deterioro cognitivo. En la actualidad, se ha recomendado la evaluación cognitiva por medio de la BICAMS (del inglés Brief International Cognitive Assessment for MS), que es una batería específica para evaluar a personas con EM, pero que no cuenta con validación en nuestro país. El presente estudio tiene como objetivo identificar el impacto de algunos factores clínicos (meses de evolución de la enfermedad y nivel de discapacidad) y personales (sexo, años de escolaridad y edad) que influyen en las medidas cognitivas de la BICAMS, a fin de contar con información relevante y precisa en un futuro proceso de validación. La muestra estuvo constituida por 38 personas con Esclerosis Múltiple Remitente Recurrente (EMRR). Los resultados mostraron que de los cinco factores clínicos observados, solo edad y sexo influyeron de manera significativa sobre los puntajes de las tres pruebas de la BICAMS. Por lo tanto, la validación de esta batería para la población chilena debiera incluir y/o controlar ambas variables de edad y sexo.

The evaluation of cognitive aspects among individuals with multiple sclerosis (MS) is key when considering intervention, because of high prevalence of cognitive impairments. At present, cognitive evaluation has been recommended by means of BICAMS (Brief International Cognitive Assessment for MS), which is a battery specifically constructed to assess individuals with MS. However, the battery has not been validated in Chile.The present study aims atdetermining the impact of clinical factors (months since condition's diagnosis and severeness level) and individual factors (sex, age, and years of schooling), which is expected to be accurate and valuable input for future validation processes. Sample consisted of 38 people with remittent-recurrent multiple sclerosis (RRMS). Results showed that only age and gender do significantly impact cognitive performance on all of three BICAMs subtests. Therefore, when validating this battery for Chilean individuals, both age and gender should be included and or controlled.

5p13. 2 Chromosomal duplication syndrome: case report and literature review / Síndrome de duplicação cromossômica 5p13. 2: relato de caso e revisão da literatura

Chromosome 5p13 duplication syndrome represents a contiguous gene syndrome involving duplication of several genes on chromosome 5p13. Some clinical phenotypes are related to it, such as: obsessive-compulsive behavior, small palpebral fissures, intellectual disability, global development delay and ocular hypertelorism. The exact mechanism behind these changes has not well known and further studies are needed for this purpose. Since it is a rare and uncommon clinical situation, the case report contributes to the knowledge of the disease and early diagnosis. This condition mainly affects the cognitive neuromuscular system. We describe an 8-year-old Brazilian patient with the duplication of chromosome 5p13.2, karyotype, whose neurodevelopmental evaluation presented cognitive impairment, severe language delay and atypical physical examination, with ocular hypertelorism, right auricular tags, congenital heart defect and long fingers. The patient was diagnosed by comparative genomic hybridization (CGH)-array revealing a 204Kb of DNA duplication. The exact mechanism behind these structural disorders is still unclear and further studies are needed for this purpose. Nevertheless, the diagnostic suspicion of this genetic alteration that, in general, presents late diagnosis, should be considered to enable better clinical support to the patients and family genetic counseling.

A síndrome da duplicação do cromossomo 5p13 representa uma síndrome genética contígua envolvendo a duplicação de vários genes contidos nesta região. Alguns fenótipos clínicos estão relacionados com ela, tais como: comportamento obsessivo compulsivo, fissuras palpebrais pequenas, déficit intelectual, atraso no desenvolvimento global e hipertelorismo ocular. Por ser uma situação clínica rara, o relato do caso contribui para a disseminação do conhecimento acerca da condição, assim como para seu diagnóstico precoce. Descrevemos uma paciente brasileira de oito anos com a duplicação do cromossomo 5p13.2, que na avaliação do neurodesenvolvimento apresentou comprometimento cognitivo, grave atraso da linguagem e dismorfismos como hipertelorismo ocular, apêndice auricular direito, sopro cardíaco, relacionado a defeito do septo ventricular, e dedos alongados. A paciente foi diagnosticada por meio da pesquisa molecular (CGH)-array com ganho de 204Kb de DNA. O mecanismo exato por trás dessas alterações estruturais ainda não está claro e são necessários mais estudos para este fim. Não obstante, a suspeita diagnóstica dessa alteração genética que, em geral, apresenta diagnóstico tardio, deve ser aventada para viabilizar melhor suporte clínico aos pacientes e aconselhamento genético familiar.

Association between physical functioning with cognition among community-dwelling older adults: a cross-sectional study / Associação entre função física e cognição em idosos da comunidade: estudo transversal

OBJECTIVE: Declines in physical and cognitive functioning often co-exist through aging. Gait-related parameters have been related to cognitive function, although it is unclear whether other measures of physical functioning are similarly related to cognition. Here, we analyzed the relationship between physical functioning with cognition in older adults. METHODS: In total, baseline data of 116 dementia-free older adults recruited from two separated clinical trials (RCT) were included (M age = 69 years, SD = 6; 71% women). We quantified cognitive functioning using the Montreal Cognitive Assessment (MoCA) and executive functioning tasks (Digit Span Forward minus Backward and verbal fluency ­ FAS and animal naming). Physical function measures included gait speed, Short-physical Performance Battery (SPPB), five-times Sit-to-Stand Test, the Timed Up and Go (TUG) test, the Six-minute Walk Test (6MWT), and lower extremity muscle strength. We used multiple linear regression analyses to explore the association between cognitive measures and each measure of physical functioning, adjusting for age, sex, education, and RCT. Regression coeficients (b), standard error (SE) and 95% confidence intervals (CI) were used to summarize main results. RESULTS: We observed a positive association between muscle strength and the MoCA (b = 0.84, SE = 0.40, 95%CI 0.05­1.64) after controlling for covariates. Significant associations were also found between the five-times-sit-to-stand test (b = -0.63, SE = 0.26, 95%CI -1.15­-0.12), TUG (b = -1.13, SE = 0.57, 95%CI -2.26­-0.01), 6MWT (b = 0.04, SE = 0.02, 95%CI 0.01­0.07), and lower extremity muscle strength (b = 1.92, SE = 0.93, 95%CI 0.09­3.77) with the FAS verbal fluency test, and between the TUG (b = -0.62, SE = 0.24, 95%CI -1.11­-0.14) with animal naming. CONCLUSION: In community-dwelling older adults, higher levels of muscle strength, dynamic balance and cardiorespiratory fitness were positively related with global cognition and executive control measures.

The association between neurocognitive functioning and clinical features of borderline personality disorder

Objective: To investigate the relationship between neurocognitive profiles and clinical manifestations of borderline personality disorder (BPD). Methods: Forty-five patients diagnosed with BPD and 35 healthy volunteers were included in the study. The BPD group was evaluated with the Borderline Personality Inventory for dissociative, impulsivity and suicidal dimensions. The Verbal Memory Processes Test and the Cambridge Neurophysiological Assessment Battery were administered to both the BPD and healthy control groups. Results: BPD patients differed from controls in sustained attention, facial emotion recognition, and deteriorated verbal memory function. A model consisting of the Dissociative Experiences Scale - Taxon (DES-T), motor impulsivity and Scale for Suicidal Behavior scores explained 52% of the variance in Borderline Personality Inventory scores. It was detected that motor impulsivity, decision-making and recognizing sadness may significantly predict DES-T scores, and response inhibition and facial emotion recognition scores may significantly predict impulsivity. Conclusion: Our findings demonstrate that the disassociation, impulsivity, and suicidality dimensions are sufficient to represent the clinical manifestations of BPD, that they are related to neurocognitive differences, and that they interact with clinical features.

Introducción: Existen pocos estudios sobre alteraciones cognitivas en niños realizados en las provincias centrales cubanas. Objetivo: Determinar la prevalencia de niños preescolares con alteraciones cognitivas. Métodos: De un universo de 25 600 niños de la provincia de Cienfuegos entre 0-6 años, se seleccionaron 825 niños preescolares entre 4 y 6 años de varias instituciones educativas y médicas. Todos se evaluaron con la prueba neuropsicológica Luria Inicial. Se usó la norma cubana de la prueba para obtener la prevalencia: percentiles 30 - 35, niños con trastornos del neurodesarrollo, y percentiles 40 - 45, niños con alteraciones cognitivas asociadas a factores psicosociales. Resultados: El 3,9 por ciento de los niños presentaron alteración cognitiva asociada a factores psicosociales, mientras que 1,4 por ciento presentaron alteraciones asociada a trastornos del neurodesarrollo. Las principales alteraciones se resumieron en cuatro tareas: cálculos sencillos, psicomotricidad, lenguaje y memoria de trabajo. En las instituciones educativas, 1 de 10 niños presentaron trastorno del neurodesarrollo, mientras que 3 de 10 niños presentaron alteraciones explicadas por causas educativas. En las instituciones médicas, el 58,0 por ciento de los niños presentó alteraciones explicadas también por causas educativas. Conclusiones: En la provincia de Cienfuegos la prevalencia de niños preescolares con alteraciones cognitivas es moderadamente alta. En especial, las alteraciones se encuentran en las funciones ejecutivas, lingüísticas y en las habilidades relacionadas con el procesamiento numérico. En las instituciones médicas, el niño con alteraciones en las funciones ejecutivas y lingüísticas es frecuente, mientras que en las instituciones educativas prevalecen las alteraciones en las funciones ejecutivas y en el procesamiento numérico(AU)

Introduction: There are few studies on cognitive alterations in children that have been carried out in the Cuban provinces of the central region. Objective: To determine the prevalence of pre-school children with cognitive alterations. Methods: From a group sample of 25 600 children from 0 to 6 years old of Cienfuegos province, there were selected 825 pre-school children in the ages from 4 to 6 years from different educational and health institutions. All the children were evaluated with the Luria Incial neuropsychological test. It was used the Cuban standard of the test to obtain the prevalence data: percentiles 30 - 35, children with neurodevelopmental disorders, and percentiles 40 - 45, children with cognitive alterations related to psychosocial factors. Results: The 3.9 percent of the children presented cognitive alterations related to psychosocial factors, while the 1.4 percent presented alterations related to neurodevelopmental disorders. The main alterations were comprised in 4 tasks: simple calculations, psychomotricity, language and working memory. In the educational institutions, 1 of 10 children presented a neurodevelopmental disorder, while 3 of 10 children presented alterations due to educative causes. In the health institutions, 58,0 percent of the children presented alterations due to educative causes. Conclusions: In Cienfuegos province, the prevalence of pre-school children with cognitive alterations is moderately high. The alterations are specially found in the executive and linguistic functions and in the abilities related with the numbers processing. In the health institutions, it is common to have children with alterations in the executive and linguistic functions, while in the educative institutions prevail the alterations in the executive functions and the numbers processing(AU)

Influência da cardiopatia congênita no desenvolvimento neuropsicomotor de lactentes / Influencia de la cardiopatía congénita en el desarrollo neuropsicomotor de los lactantes / Influence of congenital heart disease on the neuropsychomotor development of infants

RESUMO As cardiopatias congênitas (CC) estão entre as principais causas de morbimortalidade na primeira infância e os lactentes com essa condição podem apresentar atrasos no desenvolvimento neuropsicomotor (DNPM). O objetivo deste estudo foi avaliar a influência da CC no DNPM de lactentes. Trata-se de um estudo observacional com avaliação do desenvolvimento neuropsicomotor realizada pela Bayley Scales of Infant and Toddler Development (BSID-III). As condições maternas e clínicas dos lactentes foram verificadas no relatório de alta médica e na caderneta de saúde da criança, e a condição socioeconômica das famílias pelo Critério da Classificação Econômica Brasil. Para associar as variáveis clínicas e o DNPM foram utilizados o coeficiente de correlação de Spearman e o teste de razão de verossimilhança. Foram avaliados 18 lactentes, com predomínio do sexo feminino (72,2%). A maioria das mães (47,1%) possuía ensino médio completo ou superior incompleto, com média da idade de 27,2±5,5 anos. Houve correlação das escalas do BSID-III com as variáveis quantitativas analisadas: escala motora com o peso (p=0,02 e r=0,54) e com uso de oxigenoterapia (p=0,009 e r=−0,591); já para as variáveis qualitativas as associações foram entre: escala motora e condição socioeconômica (p=0,015), escala motora e comunicação interatrial - (CIA) (p=0,023) e escala da linguagem e CIA (p=0,038). A CC influenciou o DNPM, principalmente no aspecto motor. Além disso peso, diagnóstico de CIA, uso de oxigenoterapia e condição socioeconômica foram considerados como principais fatores de risco para o atraso no DNPM.

ABSTRACT Congenital heart defects (CHD) are among the main causes of morbidity and mortality in infants who has this impairment may present delays in neuropsychomotor development (NPMD). This study assesses the influence of CHD on NPMD of infants. This is an observational study assessing neuropsychomotor development performed by Bayley Scales of Infant and Toddler Development - BSID-III. The Brazilian Economic Classification Criteria was used to verify the socioeconomic status of the families and also the maternal and infants' clinical conditions were verified in the medical discharge report and in the child's health handbook. For the association between the quantitative and qualitative variables with the NPMD, the Spearman's correlation coefficient and the likelihood ratio test were used. A total of 18 infants were assessed, with a predominance of females (72.2%). Most mothers (47.1%) had complete high school or incomplete higher education, with a mean age of 27.2±5.5 years. There was a correlation between the BSID-III scales and the quantitative variables analyzed: motor scale with weight (p=0.02 and r=0.54) and oxygen therapy (p=0.009 and r=−0.591); besides that, the qualitative variables correlation were: motor scale and socioeconomic condition (p=0.015), motor scale and Interatrial Communication - IAC (p=0.023) and language with IAC scales (p=0.038). CHD influences the delay of NPMD, mainly for motor aspect. Furthermore, weight, diagnosis of IAC, use of oxygen therapy and socioeconomic status were considered the main risk factors for the delay in NPMD.

Psychometric properties of Cognitive Instruments in Vascular Dementia and Alzheimer's disease: a neuropsychological study

OBJECTIVES: To describe elderly performance in the Bender Gestalt Test (BGT) and to discriminate its score by using types of errors as comparison among healthy controls, Alzheimer's disease (AD) patients, and vascular dementia (VD) patients. METHODS: We performed a cross-sectional analysis of 285 elderly individuals of both sexes, all over 60 years old and with more than 1 year of schooling. All participants were assessed through a detailed clinical history, laboratorial tests, neuroimaging, and neuropsychological tests including the BGT, the Cambridge Cognitive Examination (CAMCOG), the Mini-Mental State Examination (MMSE), the Geriatric Depression Scale (GDS), and the Pfeffer Functional Activities Questionnaire (PFAQ). The BGT scores were not used to establish diagnosis. RESULTS: Mean BGT scores were 3.2 for healthy controls, 7.21 for AD, and 8.04 for VD with statistically significant differences observed between groups (p<0.0001). Logistic regression analysis was used to identify the main risk factors for the diagnostic groups. BGT's scores significantly differentiated the healthy elderly from those with AD (p<0.0001) and VD (p<0.0001), with a higher area under the curve, respectively 0.958 and 0.982. BGT's scores also showed that the AD group presented 12 types of errors. Types of errors evidenced in the execution of this test may be fundamental in clinical practice because it can offer differential diagnoses between senescence and senility. CONCLUSION: A cut-off point of 4 in the BGT indicated cognitive impairment. BGT thus provides satisfactory and useful psychometric data to investigate elderly individuals.

Sensitivity and specificity of the Brazilian version of the Montreal Cognitive Assessment - Basic (MoCA-B) in chronic kidney disease / Sensibilidade e especificidade da versão brasileira do Montreal Cognitive Assessment - Basic (MoCA-B) na doença renal crônica

Abstract Introduction Cognitive impairment in chronic kidney disease (CKD) is commonly associated with neuropsychiatric disorders. As a complex pathology, at all stages of CKD patients need to have a good understanding of the need for drug and nutritional adherence. Cognitive screening is the starting point for detection of cognitive impairments. Objective To determine the specificity and sensitivity of the Brazilian Portuguese version of the Montreal Cognitive Assessment - Basic (MoCA-B) for identification of cognitive impairment in the CKD population. Methods This was a cross-sectional study with 163 CKD patients undergoing hemodialysis treatment. The Mini-Mental State Examination (MMSE) and MoCA-B were administered. Results The MoCA-B has reliable internal consistency (Cronbach's alpha = 0.74). A cutoff point of ≤ 21 points provides the best sensitivity and specificity for detection of cognitive impairment. The education variable had less impact on the total MoCA-B score than on the total MMSE score. Conclusions The MoCA-B is a suitable screening instrument for evaluating the global cognition of hemodialysis patients. The results can help health professionals to conduct evaluations and plan clinical management.

Resumo Introdução O comprometimento cognitivo na doença renal crônica (DRC) é comumente associado a distúrbios neuropsiquiátricos. Sendo uma patologia complexa, a DRC, em qualquer estágio, requer que o paciente tenha uma boa compreensão da necessidade de adesão ao medicamento e à nutrição. A triagem cognitiva é o ponto de partida para a detecção de deficiências cognitivas. Objetivo Determinar a especificidade e a sensibilidade da versão em português do Brasil do Montreal Cognitive Assessment - Basic (MoCA-B) para identificação de comprometimento cognitivo na população com DRC. Métodos Este foi um estudo transversal com 163 pacientes com DRC em tratamento hemodialítico. Foram aplicados o Mini Exame do Estado Mental (MEEM) e o MoCA-B. Resultados O MoCA-B obteve consistência interna confiável (alfa de Cronbach = 0,74). Um ponto de corte de ≤ 21 pontos fornece a melhor sensibilidade e especificidade para a detecção de comprometimento cognitivo. A variável educação teve menos impacto no escore total do MoCA-B do que no escore total do MEEM. Conclusões O MoCA-B é um instrumento de triagem adequado para avaliar a cognição global de pacientes em hemodiálise. Os resultados podem ajudar os profissionais de saúde a realizar avaliações e planejar o manejo clínico.

Análises psicométricas da Escala de Distorções Cognitivas Depressivas / Psychometric analyses of the Depressive Cognitive Distortion Scale / Análisis psicométricos de la Escala de Distorsiones Cognitivas Depresivas

As distorções cognitivas são erros lógicos de pensamentos que podem alterar a realidade do sujeito, causando possíveis sintomas depressivos. O objetivo do estudo foi construir um instrumento intitulado de Escala de Distorções Cognitivas Depressivas (EDICOD) e buscar evidências de validade baseada no conteúdo e estrutura interna, utilizando análise fatorial exploratória e o modelo da Teoria de Resposta ao Item (TRI). Na etapa de construção do estudo, participaram oito juízes e 27 estudantes de graduação para uma aplicação piloto para adequação dos itens. Posteriormente, 459 indivíduos, divididos entre sujeitos não clínicos e clínicos com diagnóstico de depressão, de ambos os sexos, com faixa etária entre 18 e 60 anos. Após as análises psicométricas, a escala ficou reduzida com 36 itens, divididos em três fatores interpretáveis, sendo esses, Abstração seletiva/personalização (F1), Inferência arbitrária/maximização e minimização (F2) e por último, Pensamento dicotômico/hipergeneralização (F3). Assim, a EDICOD apresentou ser um instrumento adequado de rastreio das principais distorções cognitivas, principalmente para possível uso em ambiente clínico

Cognitive distortions are logical errors of thoughts that can alter the subject's reality, causing possible depressive symptoms. The purpose of the study was to construct an instrument titled Depression Cognitive Distortion Scale (EDICOD) and to seek evidence of validity based on content and internal structure using exploratory factorial analysis and the Item Response Theory (TRI) model. In the construction phase of the study, eight judges and 27 undergraduate students participated in a pilot application to adjust the items. Subsequently, 459 individuals, divided between non-clinical and clinical subjects with a diagnosis of depression, of both sexes, aged between 18 and 60 years, participated. After the psychometric analysis, the scale was reduced to 36 items, divided into three interpretable factors: Selective abstraction/personalization (F1), arbitrary inference/maximization and minimization (F2), and finally, dichotomous thinking/hypergeneralization (F3). Thus, EDICOD presented an adequate tool for screening the main cognitive distortions, mainly for possible use in clinical settings

Abstract Detecting and monitoring cognitive deficits in elderly populations are necessary, as they can impact individuals´ functionality. This integrative review aims to analyze the scientific production on the use of cognitive assessment instruments in Brazilian elderly individuals through articles published in the last five years, indexed in the Web of Science, Pubmed, Scopus and Bireme databases. Inclusion criteria were original articles published in English and Portuguese from 2012 to 2016, the age criterion to define elderly individuals and scores higher than 6 in the adapted CASP. The exclusion criterion was conference abstracts submitted for publication. The final sample consisted of 100 articles. Sixty-one cognitive assessment instruments were used in the studies, especially the Mini-Mental State Examination. This review features the use of cognitive instruments in the Brazilian literature, their different versions and domains evaluated. The literature includes a large number of instruments. The most used tests were the MMSE (version proposed by Brucki et al.), the Verbal Fluency Test ("animal" category) and the Digit Span Memory Test (forward span and backward span). The findings presented in this review are relevant not only for observational and experimental research but also for clinical practice.

Is the Mini-Mental State Examination the best cognitive screening test for less educated people? / O mini-exame de estado mental é o melhor teste de rastreamento cognitivo para indivíduos com menor escolaridade?

ABSTRACT Mini-Mental State Examination (MMSE) results are strongly influenced by educational level. The Brief Cognitive Screening Battery (BCSB) is an alternative assessment tool that provides more accurate results in individuals with less education. Objective: Our aim was to compare the MMSE and BCSB as screening tests. Methods: The MMSE and BCSB were assessed in 112 participants by two evaluators blind to the other test's result. Participants were classified according to their level of education. The influence of education level was analyzed using the Kruskal-Wallis and multiple comparison tests. Results: Scores of the MMSE (p < 0.0001) and the clock-drawing test (p < 0.0001) were influenced by education level but the delayed recall test score was not (p = 0.0804). The verbal fluency test (p = 0.00035) was influenced only by higher educational levels. It took three minutes less to apply the MMSE than to apply the BCSB (p < 0.0001). Conclusions: These findings suggest that the delayed recall test and the verbal fluency test of the BCSB are better than the MMSE and clock-drawing test as tools for evaluating cognition in people with limited education.

Resumo Os resultados do Mini-Exame de Estado Mental (MEEM) são consideravelmente influenciados pelo nível de escolaridade. A Bateria Breve de Rastreio Cognitivo (BBRC) é uma ferramenta de rastreamento cognitivo alternativa que fornece resultados mais acurados em indivíduos com menor nível de escolaridade. Objetivo: Comparar o MEEM e a BBRC como testes de rastreamento cognitivo. Métodos: 112 participantes foram submetidos ao MEEM e a BBRC por 2 avaliadores cegos para o resultados do outro teste. Os participantes foram classificados de acordo o nível de escolaridade. A influência do nível de escolaridade foi analisada utilizando o teste de Kruskal-Wallis e o teste de comparações múltiplas. Resultados: As pontuações do MEEM (p < 0,0001) e do teste do desenho do relógio (p < 0,0001) foram influenciadas pelo nível de escolaridade, porém o teste de memória tardia não sofreu influência do nível de escolaridade (p = 0,0804). O teste de fluência verbal (p = 0,00035) foi influenciado apenas pelos níveis educacionais mais altos. A aplicação do MEEM levou 3 minutos a menos que a da BBRC (p < 0,0001). Conclusão: Os achados desse estudo sugerem que o teste de memória tardia e o teste de fluência verbal da BBRC são mais adequados que o MEEM e o teste do desenho do relógio como ferramentas para avaliação cognitiva em populações com menor nível educacional.

Cognitive functions in children with congenital adrenal hyperplasia

ABSTRACT Objective There is controversy regarding cognitive function in patients with congenital adrenal hyperplasia (CAH). This study is aimed at the assessment of cognitive functions in children with CAH, and their relation to hydrocortisone (HC) therapy and testosterone levels. Subjects and methods Thirty children with CAH due to 21 hydroxylase deficiency were compared with twenty age- and sex-matched healthy controls. HC daily and cumulative doses were calculated, the socioeconomic standard was assessed, and free testosterone was measured. Cognitive function assessment was performed using the Wechsler Intelligence Scale - Revised for Children and Adults (WISC), the Benton Visual Retention Test, and the Wisconsin Card Sorting Test (WCST). Results The mean age (SD) of patients was 10.22 (3.17) years [11 males (36.7%), 19 females (63.3%)]. Mean (SD) HC dose was 15.78 (4.36) mg/m 2 /day. Mean (SD) cumulative HC dose 44,689. 9 (26,892.02) mg. Patients had significantly lower scores in all domains of the WISC test, performed significantly worse in some components of the Benton Visual Retention Test, as well as in the Wisconsin Card Sorting Test. There was no significant difference in cognitive performance when patients were subdivided according to daily HC dose (< 10, 10 - 15, > 15 mg/m 2 /day). A positive correlation existed between cumulative HC dose and worse results of the Benton test. No correlation existed between free testosterone and any of the three tests. Conclusion Patients with CAH are at risk of some cognitive impairment. Hydrocortisone therapy may be implicated. This study highlights the need to assess cognitive functions in CAH.

Prediction equation for the mini-mental state examination: influence of education, age, and sex / Equação de predição para o miniexame do estado mental: influência da educação, idade e sexo / Ecuación de predicción para el mini-examen del estado mental: influencia de la educación, edad y sexo

ABSTRACT The mini-mental state examination (MMSE) is a screening test used worldwide for identifying changes in the scope of cognition. Studies have shown the influence of education, age and sex in the MMSE score. However, in Brazil, the studies consider only one factor to score it. The aim of this study was to establish a prediction equation for the MMSE. An exploratory cross-sectional study was developed and trained researchers examined participants at the community. The volunteers were evaluated by the MMSE and also by the Geriatric Depression Scale (GDS). The MMSE score was the dependent variable. Age, educational level, sex, and GDS score were the independent variables. Multivariate regression analysis was used to determine the model of best prediction value for MMSE scores. A total of 250 participants aged 20-99 years, without cognitive impairment, were assessed. The educational level, age, and sex explained 38% of the total variance of the MMSE score (p<0.0001) and resulted in the following equation: MMSE=23.350+0.265(years of schooling)-0.042(age)+1.323(sex), in which female=1 and male=2. The MMSE scores can be better explained and predicted when educational level, age, and sex are considered. These results enhance the knowledge regarding the variables that influence the MMSE score, as well as provide a way to consider all of them in the test score, providing a better screening of these patients.

RESUMO O mini-exame do estado mental (MEEM) é um teste de rastreio mundialmente utilizado para identificar alterações no âmbito da cognição. Estudos têm demonstrado a influência da educação, idade e gênero na pontuação do MEEM. No entanto, no Brasil, os estudos consideram apenas um fator para a pontuação no teste. O objetivo do estudo foi estabelecer uma equação preditiva para o MEEM. Um estudo transversal exploratório foi desenvolvido e examinadores treinados avaliaram participantes da comunidade. Os voluntários foram avaliados pelo MEEM e pela Escala de Depressão Geriátrica (EDG). A pontuação do MEEM foi a variável dependente. A idade, nível educacional, gênero e pontuação na EDG foram as variáveis independentes. A análise de regressão multivariada foi utilizada para determinar o modelo de melhor valor preditivo para os escores do MEEM. Foram avaliados 250 indivíduos entre 20 e 99 anos, sem comprometimento cognitivo. O nível educacional, a idade e o sexo explicaram 38% da variância total da pontuação do MEEM (p<0,0001) e resultaram na equação: MEEM=23,350+0,265(anos de escolaridade)-0,042(idade)+1,323(gênero), em que mulher=1 e homem=2. A pontuação do MEEM pode ser melhor explicada e predita quando o nível educacional, idade e gênero são considerados. Os resultados contribuem para o conhecimento sobre as variáveis que influenciam o escore do MEEM, bem como fornece uma maneira de considerá-las na pontuação do teste, proporcionando uma melhor triagem desses pacientes.

Cognition, functionality and symptoms in patients under home palliative care

SUMMARY OBJECTIVE: Evaluating the degree of cognition, functionality, presence of symptoms and medications prescribed for patients under palliative home care. METHOD: Descriptive, cross-sectional study where 55 patients under palliative home care were interviewed. Cognition was evaluated using the Mini-Mental state examination (MM), with patients being separated into two groups: with preserved cognitive ability (MM>24), or altered (MM <24). The functionality was verified by the Palliative Performance Scale (PPS) and the patients were divided into two groups: PPS≤50 and PPS≥60. The symptoms presence was evaluated by ESAS (Edmonton Symptom Assessment System) being considered as mild (ESAS 1-3), moderate (ESAS 4-6) or severe (ESAS 7-10) symptoms. Medications prescribed to control the symptoms were registered. Statistical analysis used Student's t test (p <0.05). RESULTS: Most of the 55 patients were women (63.6%), 70.9% of these had MM> 24, 83.6% had PPS <50 and 78.2% presented chronic non-neoplastic degenerative disease. There was a significant relationship between PPS≤50 and MM≤24. Symptoms were present in 98% of patients. Asthenia was more frequently reported and was not treated in 67% of the cases. Severe pain was present in 27.3%: 46% without medication and 13% with medication, if necessary. Most patients with severe dyspnea used oxygen. CONCLUSIONS: Most of the analysed patients had their cognition preserved, presented low functionality and 98% reported the presence of symptoms. Severe pain was present in almost 1/3 of the patients without effective treatment. Re-evaluate palliative home care is suggested to optimize patient's quality of life.

RESUMO OBJETIVO: Avaliar o grau de cognição, a funcionalidade, a presença de sintomas e as medicações prescritas para pacientes sob cuidados paliativos (CP) domiciliares. MÉTODO: Estudo transversal, descritivo, em que foram entrevistados 55 pacientes sob CP domiciliares. A cognição foi avaliada pelo miniexame do estado mental (MM), sendo os pacientes separados em dois grupos: com capacidade cognitiva preservada (MM>24) ou alterada (MM<24). A funcionalidade foi verificada pela performance paliativa (PPS), sendo os pacientes divididos em dois grupos: PPS<50 e PPS>60. A presença de sintomas foi analisada pelo ESAS, sendo considerados sintomas leves (ESAS 1-3), moderados (ESAS 4-6) ou graves (ESAS 7-10). Foram anotadas as medicações prescritas para o controle dos sintomas. Para análise estatística, foi utilizado teste t student's (p<0,05). RESULTADOS: Dos 55 pacientes entrevistados, a maioria era de mulheres (63,6%), 70,9% tinham MM>24, 83,6% tinham PPS<50 e 78,2% apresentavam doença crónica degenerativa não neoplásica. Houve relação significante entre PPS<50 e MM<24. Sintomas estavam presentes em 98% dos doentes. Astenia foi mais frequentemente apontada, não sendo tratada em 67% dos casos. Dor grave estava presente em 27,3%: 46% sem medicação e 13% com medicação se necessário. A maioria dos pacientes com dispneia grave usava oxigênio. CONCLUSÃO: A maioria dos pacientes tinha cognição preservada, apresentava baixa funcionalidade e referia a presença de sintomas. Dor grave estava presente em quase 1/3 dos pacientes, não lhes sendo prescrito tratamento eficaz. Sugere-se que sejam reavaliados os CP domiciliares com o objetivo da otimização da qualidade da vida dos pacientes.

Accuracy of praxis test from Cambridge Cognitive Examination (CAMCOG) for Alzheimer's disease: a cross-sectional study

ABSTRACT BACKGROUND: Praxis impairment may be one of the first symptoms manifested in dementia, primarily in cortical dementia. The Cambridge Cognitive Examination (CAMCOG) evaluates praxis, but little is known about the accuracy of CAMCOG for diagnosing dementia. The aims here were to investigate the accuracy of praxis and its subitems in CAMCOG (constructive, ideomotor and ideational subitems) for diagnosing Alzheimer's disease (AD) among elderly patients. DESIGN AND SETTING: Cross-sectional study on community-dwelling elderly people. METHODS: 158 elderly patients were evaluated. CAMCOG, Mini-Mental State Examination and Pfeffer Functional Activities Questionnaire were used. ROC curve analysis was used to establish cutoff points. RESULTS: The total scores for praxis and the constructive subitem presented significant differences (P < 0.0001) between healthy elderly people and AD patients. Stage of dementia (clinical dementia rating, CDR = 0, 1 and 2) showed that total and constructive praxis can be used to classify the stages of dementia (mild and moderate cases), i.e. constructive praxis classified 88% of the patients with mild dementia (P < 0.0001) while total praxis classified 56% with moderate dementia. Comparison of normal controls (NC) and mild dementia cases showed specificity of 71% and sensitivity of 88% (AUC = 0.88; P < 0.0001). CONCLUSION: Some praxis subtests can have higher predictive diagnostic value for detecting Alzheimer's disease in mild stages (total praxis AUC = 0.858; P < 0.0001; constructive AUC = 0.972; P < 0.0001). Constructive praxis as measured using CAMCOG may contribute towards diagnosing dementia, because occurrence of impairment of praxis may help in recognizing an evolving dementia syndrome.

Brazilian version of the Cognitive Failures Questionnaire (CFQ): cross-cultural adaptation and evidence of validity and reliability

Objective: Cognitive failures are simple mistakes in routine activities, such as forgetting commitments and experiencing difficulty concentrating. The Cognitive Failures Questionnaire (CFQ) was designed to assess the frequency of these errors in everyday life. Although widely used in psychiatry and psychology, both in clinical and research settings, it has not been adapted for use in Brazil. Our objective was to perform cross-cultural adaptation of the CFQ for the Brazilian reality and assess its validity and reliability. Methods: The original version of the CFQ was translated into Brazilian Portuguese by two independent researchers, analyzed by a multidisciplinary board of experts, and back-translated into English. The final version was administered to 225 adults. Validity was assessed by correlation with the Self Reporting Questionnaire-20 (SRQ-20) and the Adult Attention Deficit/Hyperactivity Disorder Self-Report Scale (ASRS-18). Reliability was analyzed by calculating internal consistency and test-retest stability. Results: The adapted version of the CFQ showed significant correlations with SRQ-20 (r = -0.311), ASRS-18 inattention (r = 0.696), and hyperactivity/impulsivity (r = 0.405) scores. Reliability analysis suggests high internal consistency (0.906) and temporal stability (0.813). Conclusion: The Brazilian Portuguese version of the CFQ showed moderate correlations with other measures of mental health, as well as adequate reliability.

Diferenciación clínica del déficit cognitivo del CADASIL con respecto a otras demencias vasculares / Clinical differentiation of the cognitive deficit of CADASIL whit respect to the other vascular dementias

En el mundo hay unos 47 millones de personas que padecen demencia, y cada año se registran cerca de 10 millones de nuevos casos. La demencia es una de las principales causas de discapacidad y dependencia entre las personas mayores de 65 años. La demencia vascular constituye la segunda causa de demencia en adultos mayores y en ocasiones su diagnóstico es poco asertivo por la variedad y similitud de síntomas entre las diferentes enfermedades que originan demencia vascular, incluyendo CADASIL (acrónimo inglés de Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy); particularmente el déficit cognitivo es de los síntomas más complejos de diagnóstico, teniendo en cuenta que su manifestación clínica depende de la magnitud y localización de la lesión. La enfermedad de CADASIL, aunque se constituye como una infrecuente causa de demencia vascular de naturaleza hereditaria a nivel mundial, representa una patología de gran importancia en el ámbito nacional, dado que en familias colombianas se ha reportado mutaciones que conllevan a dicha patología. Por lo tanto, su diagnóstico y tratamiento constituyen un reto para el personal clínico, sabiendo que la identificación temprana y precisa es la mejor estrategia para evitar la progresión precoz de la enfermedad y el mejoramiento de la calidad de vida del paciente. De acuerdo con lo anterior, se realizó una revisión de la diferenciación clínica del déficit cognitivo del CADASIL con respecto a las demás demencias vasculares, con el fin de generar una herramienta que apoye la diferenciación clínica de dicha patología.

In the world, there are approximately 47 million people who have dementia, and every year they register near 10 million new cases. The dementia is one of the principal reasons for disability and dependence between people older than 65 years old. Vascular dementia constitutes the second reason of dementia in the elders, and sometimes the diagnosis is slightly assertive because of the variety and similarity of symptoms between the different diseases that originate vascular dementia, including CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy). Particularly, the cognitive deficit is one of the most complex symptoms of diagnosis, bearing in mind that its clinical manifestation depends on the magnitude and location of the injury. CADASIL disease, though it constituted as an infrequent reason of vascular dementia of hereditary nature worldwide, represents a pathology of great importance in the national area, because, in Colombian families, there have been reported mutations that carry to the above-mentioned pathology. Therefore, its diagnosis and treatment constitute a challenge for the clinical personnel, knowing that the early and precise identification is the best strategy to avoid the rapid progression of the disease and the improvement of the quality of life of the patient. In agreement with the previous information, there was made a review of the clinical differentiation of the cognitive deficit of CADASIL regarding other vascular dementias, to generate a tool that supports the clinical differentiation of the pathology mentioned above.

Cognitive screening test in primary care: cut points for low education

ABSTRACT OBJECTIVE To establish the diagnostic accuracy of the Brazilian version of the General Practitioner Assessment of Cognition (GPCOG-Br) compared to the Mini-Mental State Examination (MMSE) in individuals with low educational level. METHODS Ninety-three patients (≥ 60 years old) from Brazilian primary care units provided sociodemographic, cognitive, and functional data. Receiver operating characteristics, areas under the curve (AUC) and logistic regressions were conducted. RESULTS Sixty-eight patients with 0-4 years of education. Cases (n = 44) were older (p = 0.006) and performed worse than controls (n = 49) on all cognitive or functional measures (p < 0.001). The GPCOG-Br demonstrated similar diagnostic accuracy to the MMSE (AUC = 0.90 and 0.91, respectively) and similar positive and negative predictive values (PPV/NPV, respectively: 0.79/0.86 for GPCOG-Br and 0.79/0.81 for MMSE). Adjusted cut-points displayed high sensitivity (all 86%) and satisfactory specificity (65%-80%). Lower educational level predicted lower cognitive performance. CONCLUSIONS The GPCOG-Br is clinically well-suited for use in primary care.
