Factores de riesgo neuropsicológico y de personalidad asociados en la poliaccidentalidad laboral / Associated neuropsychological and personality risk factors in occupational polyaccidentality

Introducción: El bienestar y la salud de cada uno de los trabajadores son primordiales en el Departamento de Salud Ocupacional de la Fundación Hospital Universitario Metropolitano. Es importante que el personal goce de un nivel de vida saludable para cumplir satisfactoriamente con todas sus obligaciones y las metas planeadas de la organización. Objetivo: Analizar los factores neuropsicológicos y de personalidad asociados en un grupo de personas que se han accidentado dos o más veces (poliaccidentados). Métodos: Se desarrolló un diseño metodológico de casos y controles. Se tomó como población las bases de datos del departamento de seguridad y salud en el trabajo, con 50 trabajadores accidentados en dos o más ocasiones (poliaccidentados). Se aplicaron como técnicas de recolección de datos la escala abreviada de inteligencia Reynolds (Rist) para apreciar el coeficiente de inteligencia de los sujetos y el cuestionario de personalidad de Cattell (16 Pf), que midió 16 factores primarios y cuatro secundarios. Se utilizó la Batería Neuropsicológica de Funciones Ejecutivas y Lóbulos Frontales (BANFE) para evaluar los factores neuropsicológicos. Resultados: fue procesados mediante el paquete estadístico Statistical package Social Science (Spss) versión 21.0 que permitió realizar la prueba de hipótesis para las variables estudiadas, se utilizó la prueba U de Mann Whitney, con un criterio alfa de 0,05 y un nivel de confianza del 95 por ciento. Conclusiones: El grupo de poliaccidentados presentó alteraciones en las áreas orbito-medial, ventromedial y dorso-laterales lo que los predispone a una mayor posibilidad de realizar actividades riesgosas y presentar menor consciencia del riesgo(AU)

Introduction: The well-being and health of each of the workers are paramount in the Department of Occupational Health at Fundación Hospital Universitario Metropolitano. It is important that the staff enjoy a healthy standard of living in order to satisfactorily fulfil all their obligations and the planned goals of the organization. Objective: To look at the neuropsychological and personality factors associated in a group of individuals who have been injured two or more times (poly-accidented). Methods: A case-control methodological design was developed. The databases of the Department of Labor Safety and Health were taken as the population, with 50 workers injured on two or more occasions (poly-accidents). The abbreviated Reynolds Intelligence Scale (Rist) was applied as data collection techniques to assess the intelligence coefficient of the subjects and Cattell personality questionnaire (16 Pf), to measured 16 primary factors and four secondary factors. The Neuropsychological Battery of Executive Functions and Frontal Lobes (BANFE) was used to evaluate neuropsychological factors. Results: They were processed using the Statistical Package Social Science (Spss) version 21.0 that allowed the hypothesis test to be carried out for the variables studied, Mann Whitney U test was used, with 0.05 alpha criterion and 95 percent level of confidence. Conclusions: The group of poly-accidented patients showed alterations in the orbito-medial, ventromedial and dorso-lateral areas, which predisposes them to greater possibility of carrying out risky activities and presenting less risk awareness(AU)

Demencia frontotemporal desde una mirada neuropsicológica / Frontotemporal dementia from a neuropsychological point of view

Introducción: La riqueza de las manifestaciones neuropsicológicas de la demencia frontotemporal, ha permitido la identificación de diferentes variantes de la enfermedad, sin embargo, existen pacientes en los que se entrelazan las características clínicas de más de una variante, lo que ha llevado a cuestionar lo relativo de las clasificaciones vigentes. Objetivo: Caracterizar el funcionamiento cognitivo de un paciente donde concomitan alteraciones conductuales y del lenguaje, típicas de la demencia frontotemporal. Caso clínico: Mujer diestra, de 50 años de edad, con cambios conductuales marcados, a los cuales, de forma progresiva, se sumaron alteraciones del lenguaje, en un periodo de evolución de aproximadamente un año y seis meses. Por imágenes de tomografía axial computarizada, se confirma atrofia cortical a predominio frontal. Se emplearon para la evaluación la batería neuropsicológica breve NEUROPSI, la escala Hasegawa y la batería de evaluación frontal de Litvan; se constata predominio de alteraciones en el lenguaje impresivo y expresivo, las funciones ejecutivas y en la memoria verbal. Conclusiones: Las alteraciones detectadas, confirman la coexistencia de manifestaciones de la variante conductual (con tendencia a la desinhibición) y la variante semántica de la demencia frontotemporal(AU)

Introduction: The richness of the neuropsychological manifestations of frontotemporal dementia has allowed the identification of different variants of the disease. However, there are patients in whom the clinical characteristics of more than one variant are intertwined, which has led to question the current classifications. Objective: To characterize the cognitive functioning of a patient with concomitant behavioral and language disorders, typical of frontotemporal dementia. Case presentation: Right-handed female, 50 years old, affected by marked behavioral changes, to which language alterations were progressively added in a period of evolution of approximately one year and six months. Images of Computerized Axial Tomography that confirm cortical atrophy mainly frontal. The Neuropsychological Battery abbreviated NEUROPSI, the Hasegawa Scale and the Litvan Frontal Evaluation Battery were used for the evaluation, with a predominance of alterations in printed and expressive language, executive functions and verbal memory. Conclusions: The alterations detected confirm the coexistence of manifestations of the behavioral variant (with a tendency to disinhibition) and the semantic variant of frontotemporal dementia(AU)

Cognitive Assessment in Patients with Traumatic Brain Injury

Traumatic brain injury (TBI) is a major public health problem inWestern countries. ATBI brings many negative consequences, including behavioral and cognitive changes, which affect social adjustment and the performance of functional activities. Cognitive evaluation after TBI is a complex issue in what pertains to definition of the most appropriate questionnaires for clinical use in a comprehensive analysis of the condition of the patient. In this paper, we described a critical review of the main cognitive assessment tests currently used in clinical and research settings in patients with TBI.

Brazilian version of the European Cross-Cultural Neuropsychological Test Battery (CNTB-BR): diagnostic accuracy across schooling levels

Objective: To translate, establish the diagnostic accuracy, and standardize the Brazilian Portuguese version of the European Cross-Cultural Neuropsychological Test Battery (CNTB) considering schooling level. Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the CNTB. A total of 135 subjects aged over 60 years - 65 cognitively healthy (mean 72.83, SD = 7.71; mean education 9.42, SD = 7.69; illiterate = 25.8%) and 70 with Alzheimer's disease (AD) (mean 78.87, SD = 7.09; mean education 7.62, SD = 5.13; illiterate = 10%) - completed an interview and were screened for depression. The receiver operating characteristic (ROC) analysis was used to verify the accuracy of each CNTB test to separate AD from healthy controls in participants with low levels of education (≤ 4 years of schooling) and high levels of education (≥ 8 years of schooling). The optimal cutoff score was determined for each test. Results: The Recall of Pictures Test (RPT)-delayed recall and the Enhanced Cued Recall (ECR) had the highest power to separate AD from controls. The tests with the least impact from schooling were the Rowland Universal Dementia Assessment Scale (RUDAS), supermarket fluency, RPT naming, delayed recall and recognition, and ECR. Conclusions: The Brazilian Portuguese version of the CNTB was well comprehended by the participants. The cognitive tests that best discriminated patients with AD from controls in lower and higher schooling participants were RPT delayed recall and ECR, both of which evaluate memory.

Riesgos prenatales, perinatales y neonatales asociados a signos neurológicos blandos / Prenatal, perinatal and neonatal risks associated with soft neurological signs

Introducción: Los signos neurológicos blandos se han asociado con dificultades motoras, alteraciones comportamentales menores e incluso como factores de vulnerabilidad para la aparición de afecciones como, esquizofrenia, trastorno de déficit de atención e hiperactividad, trastorno disocial y episodios psicóticos. Aunque la investigación sobre los signos ha venido aumentando, no se tiene claridad sobre qué puede predisponer su aparición. Objetivo: Describir la asociación entre factores de riesgo prenatales, perinatales y neonatales y la aparición de los signos neurológicos blandos en niños con estos factores riesgo y en niños sin ellos. Métodos: Estudio de tipo descriptivo comparativo, de corte transversal, con diseño no experimental. La población en estudio se conformó por 550 niños y niñas, con edades entre seis y ocho años organizados. en cuatro grupos: los que presentaban riesgos prenatales, perinatales, neonatales, y el grupo que no presentaba ningún riesgo. Las aplicaciones se llevaron a cabo durante el primer semestre de 2017. Los datos se tomaron de las historias clínicas y los. signos neurológicos blandos se evaluaron a través del apartado de la Evaluación Neuropsicológica Infantil. Resultados: La mayoría de los signos neurológicos blandos presentaron diferencias significativas y valores altos en la comparación de los rendimientos en cada uno de los grupos con riesgo. Conclusiones: la presencia de riesgos prenatales, perinatales y neonatales producen una serie de alteraciones en el desarrollo del niño que se van acumulando y pueden estar asociados con la aparición de los signos neurológicos blandos(AU)

Introduction: The soft neurological signs have been associated with motor difficulties, lower behavioural alterations and even with vulnerability factors for the appearance of conditions such as schizophrenia, attention deficit disorder and hyperactivity, disocial disorder and psychotic episodes. Although research on the signs has been increasing, it is not clear what may predispose their appearance. Objective: To describe the association between prenatal, perinatal and neonatal risk factors and the appearance of the soft neurological signs in children with these risk factors and in children without them. Methods: Descriptive, comparative, cross-sectional non-experimental design´s study. The study´s population was formed by 550 boys and girls between the ages of six and eight years organized in four groups: with prenatal risks, with perinatal risks, with neonatal risks, and the group that did not present any risks. The tests were carried out during the first semester of 2017. The data were taken from the medical records and the soft neurological signs were evaluated through the item called Neuropsychological Assessment of Children. Results: Most of the soft neurological signs showed significant differences and high values in the performance comparison in each of the groups with risks. Conclusions: The presence of prenatal, perinatal and neonatal risks produce a series of alterations in the development of the child that are accumulated and may be associated with the appearance of the soft neurological signs(AU)

Construct validity of the Motor Development Scale (MDS)

Abstract Objective Construct validity for the Motor Development Scale (MDS) has not been established. The aim of this study was to examine whether the unidimensional model of MDS would be appropriate for children aged 4 to 6 years-old and provide construct validity for the items concerning this age group in Brazil. Methods A total of 938 children participated in the study (214 4-year-olds, 643 5-year-olds, and 81 6-year-olds). Confirmatory factor analysis (CFA) was used to evaluate construct validity of the MDS using a unidimensional model. Results The CFA for the unidimensional model showed excellent adequacy indices for age 4: χ2(2) = 0.581, p = 0.748, comparative fit index (CFI) = 1.000, Tucker-Lewis index (TLI) = 1.090, root mean square error of approximation (RMSEA) = 0.000 (90% confidence interval [90%CI] = 0.000 to 0.093, close fit [Cfit] = 0.841); age 5: χ2(2) = 2.669, p = 0.263, CFI = 0.993, TLI = 0.980, RMSEA = 0.023 (90%CI = 0.000 to 0.085, Cfit = 0.682), weighted root mean square residual (WRMR) = 0.407; and age 6: χ2(9) = 8.275, p = 0.506, CFI = 1.000, TLI = 1.010, RMSEA = 0.000 (90%CI = 0.000 to 0.118, Cfit = 0.653), WRMR = 0.495. Reliability was good: ω = 0.87 (95%CI = 0.81 to 0.92). Conclusion The proposed unidimensional solution for the MDS provides a concise, parsimonious and reliable way to assess motor development in children aged 4 to 6 years.

Fluência verbal de adultos e idosos do Distrito Federal: proposta normativa piloto / Verbal fluency of younger and older adults from the Federal District: proposed normative values

RESUMO Objetivo Comparar o desempenho de adultos jovens e idosos do Distrito Federal com os dados normativos. Métodos Sessenta participantes hígidos responderam aos testes de fluência verbal semântica, livre e ortográfica da Bateria Montreal de Avaliação da Comunicação. Resultados Participantes do Distrito Federal obtiveram médias menores (<0,001), comparados à média normativa. Não houve diferença no desempenho entre os grupos etários, exceto ao compará-los com indivíduos com maior escolaridade. Conclusão Na amostra do Distrito Federal avaliada, o processo de envelhecimento típico não prejudicou a fluência verbal para indivíduos que concluíram o ensino fundamental. As médias menores, em relação aos dados normativos, evidenciaram a importância de padrões normativos regionais.

ABSTRACT Purpose To compare the performance of younger and older adults from the Federal District (FD) against normative data. Methods Sixty healthy participants completed the unconstrained, phonemic and semantic verbal fluency tests of the Montreal Communication Assessment Battery. Results The FD participants obtained lower mean scores (<0.001) compared to the normative average. There was no difference in performance between the age groups, except on the comparison with high-educated individuals. Conclusion In the FD, the typical aging process did not impact verbal fluency for individuals who were educated to primary level. The lower mean scores relative to normative data highlight the importance of regional normative standards.

Evolución atípica del síndrome de Panayiotopoulos a síndrome de punta-ondas continuas durante el sueño lento / Atypical evolution of Panayiotopoulos syndrome to continuous spikes and wave's syndrome during slow sleep

Introducción: Las epilepsias focales idiopáticas constituyen uno de los grupos de epilepsias más frecuentes en la infancia. Excepcionalmente los pacientes con este tipo de epilepsias tienen evoluciones atípicas que constituyen un reto diagnóstico y terapéutico. Objetivo: Ilustrar la evolución atípica de la epilepsia focal idiopática tipo Panayiotopoulos. Presentación del caso: Adolescente de 13 años que presentó su primera crisis epiléptica a los 5 años de edad, de breve duración, mientras dormía tuvo apertura ocular, desviación de los ojos a la izquierda, abundante salivación y presentó un vómito. En tres años tuvo solo tres crisis. No recibió tratamiento con fármacos antiepilépticos hasta después de la tercera crisis, que fue más prolongada. Tras iniciar tratamiento con carbamazepina comenzó a presentar dificultades en el aprendizaje y marcada hiperactividad. Un electroencefalograma interictal de sueño demostró descargas de punta-ondas continuas en el sueño lento. Después de dos años de tratamiento se alcanzó la normalidad en el estudio electroencefalográfico de sueño, con retirada inicial de la carbamazepina, e introducción progresiva de clobazam y valproato de magnesio. Evolutivamente el paciente mantuvo las dificultades en el aprendizaje, con mejoría notable de su hiperactividad, sin recurrencia de crisis epilépticas. Conclusiones: El caso presentado constituye un ejemplo infrecuente de un paciente con una epilepsia focal idiopática con evolución atípica, probablemente inducida por la carbamazepina, con cuadro clínico-electroencefalográfico de más de dos años de duración, con mejoría favorecida por el tratamiento finalmente empleado, la evolución natural del síndrome o el efecto de ambos (AU)

Introduction: Idiopathic focal epilepsies are one of the most frequent epilepsy groups in childhood. Exceptionally, patients with this type of epilepsy have atypical evolutions that constitute a diagnostic and therapeutic challenge. Objective: To illustrate the atypical evolution of idiopathic focal epilepsy, type Panayiotopoulos. Case presentation: A 13-year-old adolescent who presented his first epileptic seizure at 5 years old, of short duration, while he slept had an eye opening, deviation of the eyes to the left, abundant salivation and vomiting. In three years he had only three seizures. He did not receive treatment with antiepileptic drugs until after the third seizure, which was longer. After starting treatment with carbamazepine, he began to have learning difficulties and marked hyperactivity. A sleep's interictal electroencephalogram showed continuous spikes and wave's discharges during the slow sleep. After two years of treatment, the normalization of the sleep electroencephalogram was achieved, with withdrawal of carbamazepine, and progressive introduction of clobazam and magnesium valproate. The patient remained evolutionarily with learning difficulties, with significant improvement in hyperactivity, without recurrence of seizures. Conclusions: The case presented is an infrequent example of a patient with idiopathic focal epilepsy with atypical evolution, probably induced by carbamazepine, with clinical-electroencephalographic symptoms during more than two years, with improvement favored by the final treatment used, the natural evolution of the syndrome or the effect of both(AU)

Motor skills assessments: support for a general motor factor for the Movement Assessment Battery for Children-2 and the Bruininks-Oseretsky Test of Motor Proficiency-2 / Avaliação de habilidades motoras: suporte a um fator motor geral para o Movement Assessment Battery for Children-2 e o Bruininks-Oseretsky Test of Motor Proficiency-2

Abstract Objective To evaluate the construct validity and model-based reliability of general and specific contributions of the subscales of the Movement Assessment Battery for Children-2 (MABC-2) and Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) when evaluating motor skills across a range of psychiatric disorders. Methods Confirmatory factor analysis (CFA) and bifactor analysis were conducted on BOT-2 data from 187 elementary school students (grades 1 to 6) (mean age: 113 ± 20 months; boys: n = 117, 62.56%) and on MABC-2 data from 127 elementary school students (grade 1) (mean age: 76 ± 2 months; boys: n = 58, 45.67%). Results The results of the CFA fit the data for multidimensionality for the BOT-2 and presented poor fit indices for the MABC-2. For both tests, the bifactor model showed that the reliability of the subscales was poor. Conclusions The BOT-2 exhibited factorial validity with a multidimensional structure among the current samples, but the MABC-2 showed poor fit indices, insufficient to confirm its multidimensional structure. For both tests, most of the reliable variance came from a general motor factor (M-factor), therefore the scoring and reporting of subscale scores were not justified for both tests.

Resumo Objetivo Avaliar a validade de construto e a confiabilidade das subescalas do Movement Assessment Battery for Children-2 (MABC-2) e do Bruininks-Oseretsky Test of Motor Proficiency-2 (BOT-2) com base em modelos das contribuições gerais e específicas ao avaliar habilidades motoras em transtornos psiquiátricos. Métodos Foram realizadas análise fatorial confirmatória (AFC) e análise bifatorial em dados de 187 escolares do primeiro ao sexto ano do ensino fundamental (idade média: 113 ± 20 meses; meninos: n = 117, 62,56%) que foram avaliados com o BOT-2, e em dados de 127 escolares do primeiro ano do ensino fundamental (idade média: 76 ± 2 meses; meninos: n = 58, 45,67%) avaliados com o MABC-2. Resultados Os resultados da AFC apresentaram índices de ajuste satisfatórios de multidimensionalidade para o BOT-2 e apresentaram índices de ajuste insatisfatórios para o MABC-2. Para ambos os testes, o modelo bifatorial mostrou que a confiabilidade das subescalas era ruim. Conclusão O BOT-2 apresentou validade fatorial com uma estrutura multidimensional entre as amostras utilizadas, mas o MABC-2 apresentou índices de ajuste insatisfatórios, insuficientes para confirmar sua estrutura multidimensional. Para ambos os testes, a maior parte da variância confiável veio de um fator motor geral (fator-M), portanto, a pontuação e o relato dos escores das subescalas não se justificaram para ambos os testes.

Validation of the Mnemonic Similarity Task - Context Version

Objective: Pattern separation (PS) is the ability to represent similar experiences as separate, non-overlapping representations. It is usually assessed via the Mnemonic Similarity Task - Object Version (MST-O) which, however, assesses PS performance without taking behavioral context discrimination into account, since it is based on pictures of everyday simple objects on a white background. We here present a validation study for a new task, the Mnemonic Similarity Task - Context Version (MST-C), which is designed to measure PS while taking behavioral context discrimination into account by using real-life context photographs. Methods: Fifty healthy subjects underwent the two MST tasks to assess convergent evidence. Instruments assessing memory and attention were also administered to study discriminant evidence. The test-retest reliability of MST-C was analyzed. Results: Weak evidence supports convergent validity between the MST-C task and the MST-O as measures of PS (rs = 0.464; p < 0.01); PS performance assessed via the MST-C did not correlate with memory or attention; a moderate test-retest reliability was found (rs = 0.595; p < 0.01). Conclusion: The MST-C seems useful for assessing PS performance conceptualized as the ability to discriminate complex and realistic spatial contexts. Future studies are welcome to evaluate the validity of the MST-C task as a measure of PS in clinical populations.

Diagnosing dementia in lower educated older persons: validation of a Brazilian Portuguese version of the Rowland Universal Dementia Assessment Scale (RUDAS)

Objective: To validate the Rowland Universal Dementia Assessment Scale for use in Brazil (RUDAS-BR). Methods: We first completed an English-Brazilian Portuguese translation and back-translation of the RUDAS. A total of 135 subjects over 60 years of age were included: 65 cognitively healthy and 70 with Alzheimer's disease (AD) according to the DSM-IV and Neurological and Communicative Disorders and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria. All participants completed an interview and were screened for depression. The receiver operating characteristic curves of the RUDAS were compared with those of the Mini Mental State Examination (MMSE) regarding the sensitivity and specificity of cutoffs, taking education into consideration. Results: The areas under the curve were similar for the RUDAS-BR (0.87 [95%CI 0.82-0.93]) and the MMSE (0.84 [95%CI 0.7-0.90]). RUDAS-BR scores < 23 indicated dementia, with sensitivity of 81.5% and specificity of 76.1%. MMSE < 24 indicated dementia, with sensitivity of 72.3% and specificity of 78.9%. The cutoff score was influenced by years of education on the MMSE, but not on the RUDAS-BR. Conclusions: The RUDAS-BR is as accurate as the MMSE in screening for dementia. RUDAS-BR scores were not influenced by education. The RUDAS-BR may improve the cognitive assessment of older persons who are illiterate or of lower educational attainment.

Normative values of the Brief Repeatable Battery of Neuropsychological Tests in a Brazilian population sample: discrete and regression-based norms / Valores normativos da Brief Repeatable Battery of Neuropsychological Tests (BRB-N) em uma amostra da população Brasileira: dados discretos e contínuos

ABSTRACT Objective Cognitive dysfunction is common in multiple sclerosis. The Brief Repeatable Battery of Neuropsychological Tests (BRB-N) was developed to assess cognitive functions most-frequently impaired in multiple sclerosis. However, normative values are lacking in Brazil. Therefore, we aimed to provide continuous and discrete normative values for the BRB-N in a Brazilian population sample. Methods We recruited 285 healthy individuals from the community at 10 Brazilian sites and applied the BRB-N version A in 237 participants and version B in 48 participants. Continuous norms were calculated with multiple-regression analysis. Results Mean raw scores and the 5th percentile for each neuropsychological measure are provided, stratified by age and educational level. Healthy participants' raw scores were converted to scaled scores, which were regressed on age, sex and education, yielding equations that can be used to calculate predicted scores. Conclusion Our normative data allow a more widespread use of the BRB-N in clinical practice and research.

RESUMO Objetivo Disfunção cognitiva é comum em pacientes com esclerose múltipla. Por isto, a Brief Repeatable Battery of Neuropsychological Tests (BRB-N) foi desenvolvida para avaliar as funções cognitivas mais frequentemente alteradas na doença. Entretanto, estão faltando dados normativos desta bateria no Brasil. Assim, nosso objetivo foi fornecer valores normativos contínuos e discretos da BRB-N para a população brasileira. Métodos Foram recrutados 285 indivíduos sadios da comunidade em 10 centros do Brasil e aplicada a versão A em 237 e a versão B em 48 sujeitos. Normas contínuas foram calculadas com análise de regressão múltipla. Resultados Escores brutos médios e 5°percentil para cada subteste são fornecidos, estratificados por idade e nível educacional. Os escores brutos dos sujeitos sadios foram convertidos em escores de escalas e postos em regressão quanto a idade, sexo e educação, fornecendo equações que podem ser usadas para calcular escores previsíveis. Conclusão Nossos dados normativos permitem um uso mais amplo da BRB-N na prática clínica e na pesquisa, fornecendo normas para dados discretos e contínuos. Normas para dados discretos deveriam ser usadas com cuidado e escores demograficamente ajustados são geralmente preferidos quando interpretando dados neuropsicológicos.

Can the CERAD neuropsychological battery be used to assess cognitive impairment in Parkinson's disease? / A bateria neuropsicológica do CERAD pode ser usada para avaliação cognitiva em pacientes com doença de Parkinson?

ABSTRACT The Consortium to Establish a Registry for Alzheimer's Disease (CERAD) neuropsychological battery was created to assess cognitive impairment in Alzheimer's disease (AD) but it is widely-used for various dementias. The aim of this study was to analyze the efficacy of using the CERAD battery in the assessment of patients with Parkinson's disease. Forty-nine patients with Parkinson's disease were divided into two groups (one with dementia and one without) using the Movement Disorder Society criteria for Parkinson's disease dementia. Cognitive deficits were assessed with the Clinical Dementia Rating Scale as the gold standard, and the CERAD. The ROC curve for the CERAD battery had an area under the curve = 0.989 (95% CI = 0.967 - 1, p<0.0001). Among the CERAD subtests, verbal fluency had the worst accuracy, and word list learning had the best accuracy. Despite the limits of this study, the CERAD battery can be efficient for assessment of cognitive deficits in Parkinson's disease patients.

RESUMO A Bateria Neuropsicológica do Consortium to Establish a Registry for Alzheimer's Disease (CERAD) foi criada para a avaliação da doença de Alzheimer (DA), mas é usada em várias demências. O objetivo deste estudo foi avaliar a efetividade dessa bateria na avaliação de pacientes com doença de Parkinson (DP). Foram avaliados 49 pacientes com DP sendo aplicadas CDR, como padrão-ouro e CERAD. Os pacientes foram divididos em dois grupos: com e sem demência, a partir dos critérios para DPP pela Movement Disorders Society. A curva ROC para o CERAD resultou em uma AUC=0.989 (95% CI = 0.967 - 1, p<0.0001). Entre os subtestes do CERAD, fluência verbal obteve a pior acurácia, e aprendizado de lista de palavras, a melhor. Apesar das limitações do estudo, a bateria do CERAD pode ser uma ferramenta eficaz na avaliação de déficits cognitivos em pacientes com DP

Escala de desenvolvimento mental de Griffiths para crianças de 0 a 2 anos - adaptação para a população brasileira / Griffiths mental development scale for children aged 0 to 2 years - adaptation for the brazilian population

Os primeiros anos de vida são fundamentais para a predição do desenvolvimento infantil normativo. Quando diagnosticada alguma alteração precocemente, a estimulação adequada irá reduzir, minimizar ou sanar as consequências deletérias desta alteração promovendo melhor qualidade de vida e desenvolvimento futuro do lactente. Para o diagnóstico precoce de alterações no desenvolvimento infantil é indispensável avaliação detalhada de todas as áreas do desenvolvimento. A Escala de Desenvolvimento Mental de Griffiths III é um instrumento de diagnóstico envolvendo cinco áreas: Fundamentos do Aprendizado, Linguagem e Comunicação, Coordenação Olho-Mão, Pessoal-Social-Emocional e Motora Grossa. O objetivo foi realizar adaptação transcultural da Escala de Desenvolvimento Mental de Griffiths III e sua normatização para os lactentes brasileiros. Após cumprimentos dos aspectos éticos, foi realizada adaptação transcultural do instrumento seguindo as etapas: tradução por dois tradutores juramentados, do inglês para o português brasileiro; síntese das traduções; retrotradução por dois nativos do idioma inglês e fluentes no idioma português brasileiro; análise por comitê de especialistas; aplicação da versão pré-final em estudo piloto; envio da documentação para os autores da Escala original. Para normatização foram avaliados 216 lactentes, com desenvolvimento típico, comprovado pelo histórico coletado na anamnese, aplicação do protocolo de Observação do Comportamento Comunicativo e do Teste de Screening de Desenvolvimento Denver II. As características quanto ao gênero e classificação socioeconômica da casuística foi proporcional à realidade brasileira. Foi realizada análise descritiva do processo de adaptação transcultural e tratamento estatístico com aplicação do Teste de Mann-Whitney e correlação de Spearman. A normatização do desempenho dos lactentes brasileiros na EDMG III foi realizada por meio da progressão linear de uma faixa etária para a seguinte (mês a mês), com a utilização de valores de média e desvio padrão suavizados. O processo de adaptação transcultural foi seguido, com necessidade de mínimas adaptações mantendo equivalência semântica, idiomática, experimental e conceitual. Não houve diferença estatisticamente significante entre desempenho de meninos e meninas; houve correlação direta e significante entre escolaridade materna e condição socioeconômica; devido às particularidades da casuística, não foi observada correlação direta entre condição socioeconômica e desempenho na Escala; verificouse correlação forte, direta e estatisticamente significante entre o desempenho dos lactentes nas cinco subescalas. Após normatização dos dados, afirma-se que a Idade de Desenvolvimento se apresenta similar entre as Subescalas, seguindo um padrão de aumento na pontuação bruta de acordo com o aumento da idade cronológica, seguindo o curso do desenvolvimento típico. Concluiu-se que foi realizada a adaptação transcultural da Escala de desenvolvimento Mental Griffiths III de 0 a 72 meses, incluindo o Livro de Anotações e o Livro de Desenho. A normatização deste instrumento foi concluída para a faixa etária de 0 a 24 meses, com valores normativos referente à Idade de Desenvolvimento.(AU)

The first years of life are fundamental to the prediction of normative infant development. When an early diagnosis is made, adequate stimulation will reduce, minimize or remedy the deleterious consequences of this change, promoting better quality of life and future development of the infant. For the early diagnosis of changes in child development, a detailed evaluation of all areas of development is indispensable. The Griffiths Mental Development Scale III is a diagnostic tool involving five areas: Fundamentals of Learning, Language and Communication, Eye-Hand Coordination, Personal-Social-Emotional and Gross Motor. The objective was to perform transcultural adaptation of the Griffiths Mental Development Scale III and its normalization for Brazilian infants. After observing the ethical aspects, the transcultural adaptation of the instrument was carried out following the steps: translation by two sworn translators, from English into Brazilian Portuguese; synthesis of translations; back translation by two native speakers of the English language and fluent in the Brazilian Portuguese language; analysis by expert committee; application of the prefinal version in a pilot study; sending the documentation to the authors of the original Scale. For normalization, 216 infants were evaluated, with a typical development, as evidenced by the history collected in the anamnesis, application of the Communicative Behavior Observation protocol and the Denver II Development Screening Test. The characteristics of the gender and socioeconomic classification of the sample were proportional to the Brazilian reality. A descriptive analysis of the cross-cultural adaptation process and statistical treatment with Mann-Whitney test and Spearman correlation were performed. The normalization of the performance of Brazilian infants in the EDMG III was performed through linear progression from one age group to the next (month to month), using mean and standard deviation values smoothed. The process of cross-cultural adaptation was followed, with the need for minimal adaptations maintaining semantic, idiomatic, experimental and conceptual equivalence. There was no statistically significant difference between boys' and girls' performance; there is a direct and significant correlation between maternal schooling and socioeconomic status; due to the particularities of the sample, no direct correlation was observed between socioeconomic status and performance in the Scale; there was a strong, direct and statistically significant correlation between infant performance in the five subscales. After normalization of the data, it is stated that the Development Age is similar among the subscales, following a pattern of increase in the gross score according to the increase of the chronological age, following the course of the typical development. It was concluded that the transcultural adaptation of the Griffiths Mental Development Scale III from 0 to 72 months was carried out, including the Record Book and the Drawing Book. The normalization of this instrument was completed for the age group from 0 to 24 months, with normative values referring to the Age of Development.(AU)

Standardization of the face-hand test in a Brazilian multicultural population: prevalence of sensory extinction and implications for neurological diagnosis

OBJECTIVE: The face-hand test is a simple, practical, and rapid test to detect neurological syndromes. However, it has not previously been assessed in a Brazilian sample; therefore, the objective of the present study was to standardize the face-hand test for use in the multi-cultural population of Brazil and identify the sociodemographic factors affecting the results. METHODS: This was a cross sectional study of 150 individuals. The sociodemographic variables that were collected included age, gender, race, body mass index and years of education. Standardization of the face-hand test occurred in 2 rounds of 10 sensory stimuli, with the participant seated to support the trunk and their vision obstructed in a sound-controlled environment. The face-hand test was conducted by applying 2 rounds of 10 sensory stimuli that were applied to the face and hand simultaneously. The associations between the face-hand test and sociodemographic variables were analyzed using Mann-Whitney tests and Spearman correlations. Binomial models were adjusted for the number of face-hand test variations, and ROC curves evaluated sensitivity and specificity of sensory extinction. RESULTS: There was no significant relationship between the sociodemographic variables and the number of stimuli perceived for the face-hand test. There was a high relative frequency of detection, 8 out of 10 stimuli, in this population. Sensory extinction was 25.3%, which increased with increasing age (OR=1.4[1:01–1:07]; p=0.006) and decreased significantly with increasing education (OR=0.82[0.71-0.94]; p=0.005). CONCLUSION: In the Brazilian population, a normal face-hand test score ranges between 8–10 stimuli, and the results indicate that sensory extinction is associated with increased age and lower levels of education.

The correlation between EDSS and cognitive impairment in MS patients. Assessment of a Brazilian population using a BICAMS version / Correlação entre EDSS e déficit cognitivo em pacientes com EM. Avaliação de uma população brasileira usando uma versão do BICAMS

ABSTRACT Multiple sclerosis (MS) may present with a cognitive impairment as disabling as the physical disabilities. Therefore, routine cognitive evaluation is pivotal. Valid and reliable neuropsychological tests are essential in follow-up and to define future therapeutic interventions. Objectives To investigate the correlation between the disabilities of MS patients and their cognitive impairment assessed by the Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS). Methods Forty patients with definitive diagnoses of MS were selected. The correlation coefficient (r) between the Expanded Disability Status Scale (EDSS) and the neuropsychological tests of BICAMS were calculated. Results The correlation was clinically substantial and significant with r = 0.55 (p < 0.01) in the Symbol Digit Modalities Test (SDMT), 0.54 (p < 0.01) in the Brief Visuospacial Memory Test (BVMT) and 0.40 (p < 0.05) in the California Verbal Learning Test (CVLT). Conclusion BICAMS has easy and satisfactory application and evaluation for routine visits and presents a significant correlation with the EDSS. Its use may be indicated for screening and monitoring of cognitive impairment in patients with MS.

RESUMO A esclerose múltipla (EM) pode apresentar um déficit cognitivo (DC) tão devastador quanto suas debilidades físicas. Uma avaliação cognitiva rotineira é essencial e testes neuropsicológicos (TNs) validados e confiáveis são fundamentais no acompanhamento e definição de futuras intervenções terapêuticas. Objetivos Investigar a correlação entre o estado de incapacidade física de pacientes com EM e o comprometimento cognitivo, avaliado pelo Brief International Cognitive Assessment for Multiple Sclerosis (BICAMS). Métodos Foram calculados coeficientes de correlação (r) entre a Expanded Disability Status Scale (EDSS) e resultados dos testes do BICAMS em quarenta pacientes com diagnóstico definitivo de EM. Resultados A correlação foi clinicamente substancial e significativa, com r = 0.55 (p < 0.01, no Symbol Digit Modalities Test (SDMT), 0.54 (p < 0.01) no Brief Visuospacial Memory Test (BVMT) e 0.40 (p < 0.05) no California Verbal Learning Test (CVLT). Conclusão O BICAMS é de fácil e satisfatória aplicação e avaliação em visitas de rotina e apresenta uma correlação significativa com a EDSS. Seu uso pode ser indicado como rotina no acompanhamento do (DC) em portadores de EM.

Phonemic verbal fluency task in adults with high-level literacy / Fluência verbal fonêmica em adultos de alto letramento

ABSTRACT Objective: To establish normative parameters for the F-A-S form of the phonemic verbal fluency test, in a population of Brazilian Portuguese speaking adults with high-level literacy. Methods: The sample comprised 40 male and female volunteers aged 19 to 59 years, and at least 8 years of formal education. Volunteers were first submitted to the Mini-Mental State Examination and the Clock Drawing cognitive screening tests, then to the F-A-S Verbal Phonemic Fluency Test; in this test, examinees were given 60 seconds to generate as many words as possible beginning with each of the three test letters. Results: The means for number of words beginning the letters F, A and S and for total number of words beginning with either letter generated per minute corresponded to 15.3, 14.4, 13.9 and 43.5, respectively. Conclusion: Reference values obtained from young adults with high levels of literacy submitted to the F-A-S Verbal Phonemic Fluency Test in this study were similar to those reported in the international literature. These reference values can be used for clinical assessment of language disorder and neuropsychological evaluation.

RESUMO Objetivo: Obter parâmetros de normalidade na tarefa de fluência verbal fonêmica, versão F-A-S, em uma população de alto letramento de adultos falantes do português brasileiro. Métodos: A amostra foi constituída por 40 voluntários, de ambos os sexos, com idade entre 19 e 59 anos, e com mais de 8 anos de estudo. Todos os voluntários foram inicialmente submetidos ao Miniexame do Estado Mental e ao Teste do Desenho do Relógio, para fins de rastreio cognitivo, e, então, ao Teste de Fluência Verbal Fonêmica F-A-S. Neste último, os indivíduos foram orientados a produzirem o maior número de palavras que conseguissem, iniciadas com cada uma das três letras ditas pelo examinador, em um intervalo de 60 segundos cada. Resultados: As médias das palavras produzidas com as letras F-A-S foram as seguintes: “F” = 15,3 palavras por minuto; “A” = 14,4 palavras por minuto; e “S” = 13,9 palavras por minuto. A média do total de palavras emitidas iniciada com todas as letras do teste foi de 43,5 palavras. Conclusão: Foram obtidos valores de referência para o Teste de Fluência Verbal Fonêmica F-A-S para indivíduos adultos jovens de alto grau de letramento semelhantes aos de estudos internacionais. Tais valores podem ser utilizados na avaliação clínica de transtornos da linguagem e na avaliação neuropsicológica.

Instrumentos para avaliação de apraxia de fala infantil / Tools for the assessment of childhood apraxia of speech

RESUMO Objetivo: Revisar sistematicamente na literatura os principais instrumentos utilizados para avaliação da apraxia de fala infantil. Estratégia de pesquisa: Realizou-se busca nas bases Scopus, PubMed e Embase Critérios de seleção: Foram selecionados estudos empíricos que utilizaram instrumentos de avaliação da apraxia de fala infantil. Análise dos dados: A seleção dos artigos foi realizada por dois pesquisadores independentes. Resultados: Foram encontrados 695 resumos. Após a leitura dos resumos, foram selecionados 12 artigos completos. Foi possível identificar cinco instrumentos: Verbal Motor Production Assessment for Children, Dynamic Evaluation of Motor Speech Skill , The Orofacial Praxis Test , Kaufman Speech Praxis Test for children e o Madison Speech Assessment Protocol . São poucos os instrumentos utilizados para identificação da apraxia de fala infantil e a maioria destina-se à avaliação da realização de praxias e/ou movimentos orofaciais, sequências de movimentos orofaciais, articulação de fonemas simples, fonemas complexos e sílabas, fala espontânea, além da adequação da prosódia. Conclusões: Percebe-se que existem instrumentos que se propõem a avaliar e diagnosticar a apraxia de fala infantil. No entanto, ainda são escassos os estudos sobre esse tema em nível nacional, bem como protocolos padronizados e validados para a população brasileira que avaliem e ajudem em um diagnóstico preciso.

ABSTRACT Purpose: This study systematically reviews the literature on the main tools used to evaluate childhood apraxia of speech (CAS). Research strategy: The search strategy includes Scopus, PubMed, and Embase databases. Selection criteria: Empirical studies that used tools for assessing CAS were selected. Data analysis: Articles were selected by two independent researchers. Results: The search retrieved 695 articles, out of which 12 were included in the study. Five tools were identified: Verbal Motor Production Assessment for Children, Dynamic Evaluation of Motor Speech Skill, The Orofacial Praxis Test, Kaufman Speech Praxis Test for Children, and Madison Speech Assessment Protocol. There are few instruments available for CAS assessment and most of them are intended to assess praxis and/or orofacial movements, sequences of orofacial movements, articulation of syllables and phonemes, spontaneous speech, and prosody. Conclusion: There are some tests for assessment and diagnosis of CAS. However, few studies on this topic have been conducted at the national level, as well as protocols to assess and assist in an accurate diagnosis.

Bateria Montreal de Avaliação da Comunicação - versão portuguesa: efeito da idade e escolaridade / Montreal Communication Evaluation Battery - Portuguese version: age and education effects

RESUMO Objetivos: Verificar o efeito das variáveis idade e escolaridade no desempenho de adultos saudáveis na Bateria Montreal de Avaliação da Comunicação, versão portuguesa (MAC-PT). Métodos: A amostra foi composta por 90 indivíduos portugueses, falantes do Portugês Europeu, distribuídos em 9 grupos de acordo com a escolaridade (4 a 9; 10 a 13; e mais de 13 anos de ensino formal) e com a idade (19 a 40; 41 a 64; e 65 a 80 anos). Para análise de comparação entre grupos, utilizou-se o testetwo-way ANOVA, com post-hoc Bonferroni (p≤0,05). Resultados: Verificou-se que o desempenho dos indivíduos foi influenciado pela variável idade nas tarefas pragmático-inferencial, discursiva e prosódica. Já a escolaridade influenciou o desempenho em todos os processamentos avaliados pela MAC-PT. Conclusão: As variáveis idade e escolaridade influenciaram o desempenho comunicativo e devem ser consideradas no processo de avaliação de pacientes neurológicos.

ABSTRACT Purpose: To verify age and education effects on communication performance of healthy adults in the Montreal Communication Evaluation Battery, Portuguese version (MAC-PT). Methods: The sample comprised 90 healthy adults from Portugal, European Portuguese speakers, divided into nine groups according to educational level (4-9, 10-13, and >13 years of formal schooling) and age (19-40, 41-64, and 65-80 years). The influence of age and education was assessed by comparing mean scores between groups, using a two-way analysis of variance followed by Bonferroni post hoc tests (p ≤0.05). Results: The results showed that participants' performance was influenced by age in pragmatic-inferential, discursive, and prosodic tasks. Education had the greatest influence on the performance in all processes evaluated by the MAC-PT. Conclusion: Age and education seem to influence the communicative performance and should be considered in the assessment of neurological patients.

Screening of cognitive impairment in patients with Parkinson's disease: diagnostic validity of the Brazilian versions of the Montreal Cognitive Assessment and the Addenbrooke's Cognitive Examination-Revised / Rastreio de comprometimento cognitivo em pacientes com doença de Parkinson: validade diagnóstica das versões brasileiras da Montreal Cognitive Assessment e do Addenbrooke's Cognitive Examination-Revised

ABSTRACTObjective The aim of the present study is to examine the accuracy of the Brazilian versions of the Montreal Cognitive Assessment (MoCA) and the Addenbrooke's Cognitive Examination-Revised (ACE-R) to screen for mild cognitive impairment (PDMCI) and dementia (PDD) in patients with Parkinson's disease (PD).Method Both scales were administered to a final convenience sample of 79 patients with PD. Patients were evaluated by a neurologist, a psychiatrist and a neuropsychologist using UPDRS, Hoehn and Yahr and Schwab and England scales, global deterioration scale, a psychiatric structured interview, Mattis Dementia Rating Scale and other cognitive tests.Results There were 32 patients with PDMCI and 17 patients with PDD. The MoCA and the ACE-R were able to discriminate patients with PDD from the others.Conclusion Both scales showed to be useful to screen for dementia but not for mild cognitive impairment in patients with PD.

RESUMOObjetivo O objetivo do estudo foi avaliar a acurácia das versões Brasileiras das escalas: Montreal Cognitive Assessment (MoCA) e Addenbrooke's Cognitive Examination-Revised (ACE-R), no rastreamento de comprometimento cognitivo leve (CCL) e demência em pacientes com doença de Parkinson (DP).Método As duas escalas foram aplicadas a uma amostra de conveniência de 79 pacientes com DP. Os pacientes foram avaliados por um neurologista, um psiquiatra e uma neuropsicóloga que utilizaram a UPDRS, a escala de Hoehn e Yahr, a escala de Schwab e England, a escala de deterioração global, uma entrevista psiquiátrica estruturada, a escala de demência de Mattis e outros testes cognitivos.Resultados 32 pacientes foram diagnosticados com CCL e 17 com demência. A MoCA e o ACE-R foram capazes de discriminar pacientes com demência dos demais.Conclusão As duas escalas se mostraram úteis para rastrear demência, mas não CCL, em pacientes com DP.
