Alterações de linguagem em pacientes pós lesão encefálica adquirida na fase aguda / Language changes in patients after brain injury acquired in the acute phase

Caracterizar as alterações de linguagem encontradas em pacientes com lesão encefálica adquirida em fase aguda Métodos: Trata-se de uma pesquisa observacional, descritiva do tipo transversal. A avaliação foi realizada nas enfermarias de um hospital de urgências, com pacientes de idade superior a 18 anos, diagnóstico de lesão encefálica adquirida e tempo de internação de até 60 dias. O protocolo utilizado incluiu avaliação das praxias orais, expressão, compreensão da linguagem oral e leitura. Ao final, foi possível apresentar as hipóteses diagnósticas de afasias fluentes e não fluentes, disartria e sem alteração de linguagem. A análise dos dados foi realizada por meio de estatística descritiva através da distribuição de frequência absoluta e frequência relativa Resultados: A amostra foi composta por 24 pacientes sendo a maioria do gênero masculino, com média de idade de 51 anos. O diagnóstico de maior frequência foi Acidente Vascular Cerebral. Dos pacientes avaliados, 79% tiveram alterações de fala/linguagem. As hipóteses diagnósticas fonoaudiológicas encontradas foram: afasia global, afasia de broca, afasia transcortical mista, afasia de condução, afasia transcortical motora, afasia transcortical sensorial e disartria. Conclusão: A afasia global foi o transtorno de linguagem de maior ocorrência entre os indivíduos, bem como o gênero masculino e o acidente vascular cerebral. A avaliação da linguagem de pacientes com lesões encefálicas adquiridas na fase aguda é pertinente, pois promove o levantamento de alterações desde as perceptíveis até as mais discretas

To characterize the language disorders found in patients with brain injury acquired in the acute phase Methods: This is an observational, descriptive cross-sectional study. The evaluation was carried out in the wards of an emergency hospital, with patients aged over 18 years, diagnosed with acquired brain injury and hospitalization time of up to 60 days. The protocol used included assessment of oral praxis, expression, comprehension of oral language and reading. In the end, it was possible to present the diagnostic hypotheses of fluent and non-fluent aphasias, dysarthria and without language alteration. Data analysis was performed using descriptive statistics through the distribution of absolute frequency and relative frequency. Results: The sample consisted of 24 patients, most of whom were male, with a mean age of 51 years. The most frequent diagnosis was Cerebral Vascular Accident. Of the evaluated patients, 79% had speech/language disorders. The speech-language diagnostic hypotheses found were: global aphasia, drill aphasia, mixed transcortical aphasia, conduction aphasia, motor transcortical aphasia, sensory transcortical aphasia and dysarthria. Conclusion: Global aphasia was the most frequent language disorder among individuals, as well as males and stroke. The evaluation of the language of patients with brain injuries acquired in the acute phase is relevant, as it promotes the survey of changes from the perceptible to the most discreet

Formal language assessment in low-educated persons with aphasia: can the lesion effect be distinguished from the education effect? / Avaliação da linguagem em pacientes afásicos com baixa escolaridade: o impacto da lesão neurológica pode ser discriminado da baixa escolaridade?

ABSTRACT Background: Language tests are important in the assessment and follow up of people with aphasia (PWA). However, language assessment in the low literacy population is still a challenge. Objective: To investigate whether a formal evaluation of aphasia is able to distinguish the neurological effect from the effect of low educational level in people with post-stroke aphasia. Methods: The sample consisted of a group of 30 aphasic subjects (AG) and a control group (CG) of 36 individuals, both with an educational level of 1-4 years. The Brazilian Montreal-Toulouse Language Assessment battery was applied to all subjects. Results: There were statistically significant differences between the groups in 19 out of the 20 tasks analyzed. Conclusions: These results suggest that formal evaluation procedures are able to detect language disorders resulting from stroke, even in subjects with low educational level.

RESUMO Antecedentes: Os testes de linguagem são importantes para a avaliação e o acompanhamento de pacientes afásicos. Apesar disso, a avaliação de linguagem em indivíduos com baixa escolaridade ainda é um desafio. Objetivo: Investigar se a avaliação formal da afasia é capaz de diferenciar o efeito da lesão neurológica versus o efeito da baixa escolaridade em pacientes afásicos, acometidos por acidente vascular cerebral (AVC). Métodos: A amostra foi composta de um grupo de 30 sujeitos afásicos (AG) e um grupo controle (CG) de 36 indivíduos, todos com um a quatro anos de escolaridade. A Bateria Montreal-Toulouse de Avaliação da Linguagem foi administrada a todos os participantes. Resultados: Das 20 tarefas analisadas, 19 apresentaram diferenças significativas entre os grupos. Conclusões: Os resultados sugerem que procedimentos formais de avaliação são capazes de identificar as alterações linguísticas ocasionadas por um AVC, também em pacientes com baixa escolaridade.

Desfechos de deglutição e alimentação associados à intubação orotraqueal e à traqueostomia em pediatria / Swallowing and feeding outcomes associated with orotracheal intubation and tracheostomy in pediatrics

RESUMO Objetivo verificar os desfechos de deglutição e alimentação de pacientes pediátricos submetidos à intubação orotraqueal (IOT) prolongada, considerando aqueles que evoluíram para traqueostomia após. Métodos estudo de coorte retrospectivo, realizado por meio da análise de prontuários de pacientes admitidos em Unidade de Terapia Intensiva Pediátrica e acompanhados até a alta hospitalar, entre março de 2017 e dezembro de 2018. Resultados dos 51 pacientes incluídos, 64,7% eram do gênero masculino e a mediana de idade foi de 6,7 meses. Pacientes submetidos à IOT por mediana de sete dias apresentaram disfagia orofaríngea (DOF) leve e, quando submetidos a mais de 14 dias, apresentaram DOF moderada/grave, distúrbio alimentar pediátrico (DAP) com características de recusa alimentar e contraindicação de alimentação por via oral na alta hospitalar. Dentre os pacientes, 74,5% foram submetidos apenas à IOT e 25,5% evoluíram para traqueostomia, após. Pacientes traqueostomizados apresentaram maior ocorrência de alta hospitalar com DOF moderada/grave, DAP com características de recusa alimentar e uso de via alternativa de alimentação, em comparação a pacientes sem traqueostomia (p=0,001). Comparado ao diagnóstico inicial, pacientes não traqueostomizados tiveram diagnóstico final com graus mais leves de disfagia (p<0,001). Conclusão o tempo de IOT e a presença de traqueostomia são fatores associados ao diagnóstico fonoaudiológico de DOF moderada/grave, à presença de sinais de DAP com características de recusa alimentar e à necessidade de via alternativa de alimentação, persistentes até a alta hospitalar, sendo achados fonoaudiológicos frequentes entre os desfechos de deglutição/alimentação em pediatria.

ABSTRACT Purpose To verify the swallowing and feeding outcomes of pediatric patients undergoing prolonged OTI, considering those who progressed to tracheostomy afterward. Methods Retrospective cohort study, carried out by analyzing the medical records of patients admitted to the Pediatric ICU and followed up until hospital discharge, between 03/2017 and 12/2018. Results Of the 51 patients included, 64.7% were male and the median age 6.7 months. Patients undergoing OTI for a median of 7 days had mild dysphagia and when submitted for more than 14 days had moderate/severe dysphagia and PFD with characteristics of food refusal, with contraindication to oral feeding at hospital discharge. 74.5% of the patients underwent OTI only and 25.5% progressed to tracheostomy afterward. Tracheostomized patients had a higher occurrence of hospital discharge with moderate/ severe oropharyngeal dysphagia, pediatric feeding disorder (PFD) with characteristics of food refusal and alternative method of feeding compared to patients without tracheostomy (p=0.001). Non-tracheostomized patients had a final diagnosis with milder degrees of dysphagia when compared to the initial diagnosis (p<0.001). Conclusion The time of OTI and the presence of tracheostomy are factors associated with the speech-language pathology diagnosis of moderate/severe oropharyngeal dysphagia, presence of signs of PFD with characteristics of food refusal and the need for an alternative method of feeding that persists until hospital discharge, being frequent findings among the swallowing/feeding outcomes in pediatrics.

Afasia global. Documentación de 3 años tratamiento desde la fase aguda a crónica / Global aphasia. Documentation of 3 years of treatment from acute to chronic phase

Aphasia as a sequel to stroke is present between 14-28% worldwide and in 20% in the Chilean population. The most serious form is called global aphasia, with a severe alteration of the comprehensive and expressive language, with a poor communicative prognosis and quality of life for the patient and families. The objective of this case is to describe the evolution of a person with global aphasia from the acute phase to 3 years of speech therapy treatment, who achieved a successful evolution of their language, communication and quality of life. This paper presented anamnestic data of the case, initial and systematic evaluation of linguistic functions and impact on quality of life, and the results that document its progress in 3 years. Also, this case is described dynamic person-centered treatment and methodology to start in the acute phase with severe compromise (aphasic cocient 6/100 Cutoff 93.8) and after 3 years improve to mild-moderate aphasia (76/100 points). Progress in vitality, communication, physical and psychosocial aspects and the mean quality of life score are described quantitatively. (AU)

Sensibilidad y especificidad del Test ScreeLing en usuarios afásicos en etapa aguda: un análisis preliminar / Sensitivity and Specificity of the Spanish version of the ScreeLing Test in aphasic patients at the acute phase: a pilot study

En Chile, entre un 20% y un 38% de los usuarios que sufren un ataque cerebro-vascular (ACV) presentan afasia. Pese a su alta prevalencia no existen herramientas validadas que permitan realizar una caracterización lingüística temprana de la afasia. Por lo anterior, el objetivo del presente trabajo es analizar la sensibilidad y especificidad de la versión en español del ScreeLing en una muestra de usuarios afásicos después de producido un ACV. Se trata de un estudio transversal analítico en el cual se aplicó el test ScreeLing a 13 usuarios afásicos tras primer evento de ACV en etapa aguda (< 6 semanas tras ACV) y a 56 adultos neurológicamente sanos. Adicionalmente, se evaluó el nivel comprensivo y el lenguaje espontáneo de usuarios con afasia, con la versión abreviada del Token Test y Escala de Severidad de la Afasia (ASRS). Se construyeron modelos mediante regresiones logísticas, obteniendo sus respectivas áreas bajo la curva ROC. Los resultados muestran que el equilibrio entre sensibilidad y especificidad para el puntaje global del test ScreeLing se estableció en 67 puntos, obteniendo una sensibilidad del 94,6% y especificidad del 100%. El área bajo la curva ROC alcanzó 0,99 (IC 95%: 0,97-1,00). En las subpruebas sintáctica y fonológica se alcanzó un puntaje de corte de 21 puntos, mientras que en la subprueba semántica se lograron 22 puntos. Se concluye que el ScreeLing en español posee una alta sensibilidad y especificidad para la detección de déficits lingüísticos post ACV similar a los resultados encontrados en la versión original del test en holandés. Esfuerzos futuros deben concentrarse en ampliar la muestra de usuarios afásicos con distintos perfiles de severidad.

In Chile, aphasia is present in 20% to 30% of stroke patients. Currently, speech and language therapists do not have a standardized test to characterize aphasic patients' linguistics disorders at the acute phase. The aim of this study iso analyze the sensibility and specificity of the Spanish version of the ScreeLing test in aphasic patient post-stroke at the acute stage. To do so, in a transversal study design, acute aphasic patients (< 6 weeks post-stroke) and healthy adults were evaluated with the Spanish version of the ScreeLing test. Additionally, language comprehension and spontaneous speech were assessed with the shortened version of the Token Test and the Aphasia Severity Rating Scale, respectively. We calculated the Area Under ROC Curve (AUC) to choose the cut-off that provided the best balance between sensibility and specificity. We included 13 aphasic patients and 56 healthy adults. The best balance between sensibility and specificity was found to be with 67 points, with a sensibility of 94,6% andspecificity of 100%. The AUC ROC was 0,99 (IC 95%: 0,97-1,00). For the subtest measuring syntax and phonology, the cut-off score was 21 points, and for the semantic subtest, 22 points. In conclusion, the Spanish version of the ScreeLing test, similar to its original Dutch version, demonstrated high specificity and sensibility to detect linguistic deficits in acute aphasic patients post-stroke. Future efforts aim to increase the sample size of patients considering differentlanguage severity profiles.

Brief Montreal-Toulouse Language Assessment Battery: adaptation and content validity

Background Evaluating patients in the acute phase of brain damage allows for the early detection of cognitive and linguistic impairments and the implementation of more effective interventions. However, few cross-cultural instruments are available for the bedside assessment of language abilities. The aim of this study was to develop a brief assessment instrument and evaluate its content validity. Methods Stimuli for the new assessment instrument were selected from the M1-Alpha and MTL-BR batteries (Stage 1). Sixty-five images were redesigned and analyzed by non-expert judges (Stage 2). This was followed by the analysis of expert judges (Stage 3), where nine speech pathologists with doctoral training and experience in aphasiology and/or linguistics evaluated the images, words, nonwords, and phrases for inclusion in the instrument. Two pilot studies (Stage 4) were then conducted in order to identify any remaining errors in the instrument and scoring instructions. Results Sixty of the 65 figures examined by the judges achieved inter-rater agreement rates of at least 80%. Modifications were suggested to 22 images, which were therefore reanalyzed by the judges, who reached high levels of inter-rater agreement (AC1 = 0.98 [CI = 0.96-1]). New types of stimuli such as nonwords and irregular words were also inserted in the Brief Battery and favorably evaluated by the expert judges. Optional tasks were also developed for specific diagnostic situations. After the correction of errors detected in Stage 4, the final version of the instrument was obtained. Conclusion This study confirmed the content validity of the Brief MTL-BR Battery. The method used in this investigation was effective and can be used in future studies to develop brief instruments based on preexisting assessment batteries.

Adaptación y datos psicométricos de la versión chilena del Protocolo de Exploración de Habilidades Metalingüísticas Naturales en Afasia (MetAphAs) / Adaptation and psychometric data of the Exploration of Natural Metalinguistic Skills in Aphasia Protocol (MetAphAs) - Chilean version

RESUMEN Objetivo: El objetivo de este estudio fue adaptar transculturalmente el Protocolo de Exploración de Habilidades Metalingüísticas Naturales en Afasia (MetAphAs), contribuyendo a la aplicación futura del instrumento en la población afásica chilena. Método: la muestra corresponde a 72 individuos sanos de la región de Valparaíso, de 50 a 85 años. El Protocolo MetAphAs mide las habilidades metalingüísticas naturales y presenta los elementos básicos en los que debe basarse una exploración de la dimensión metacognitiva involucrada en el comportamiento verbal. La validez se verificó mediante el coeficiente alfa de Cronbach, incluidos los valores de cada una de las 6 secciones; las correlaciones entre las variables fueron analizadas por el coeficiente de Pearson. Resultados: el 64% de la muestra correspondió a mujeres y el 36% a hombres, con el mayor grupo de edad de participación de 61 a 70 años; se verifica una correlación adecuada entre las variables según el coeficiente de Pearson y los valores altamente positivos según el alfa de Cronbach. Conclusión: el uso del protocolo fue factible y relevante, con datos que demostraron una alta confiabilidad. Los resultados obtenidos y las ventajas indicadas alientan el uso de este tipo de instrumento como una opción viable para la validación en afásicos chilenos.

ABSTRACT Purpose: This study aimed to cross culturally adapt the Protocol for the Exploration of Natural Metalinguistic Skills in Aphasia (MetAphAs), contributing to the future application in the aphasic Chilean population. Method: The sample corresponds to 72 healthy subjects in the region of Valparaíso, between the ages of 50 to 85. The MetAphAs measures natural metalinguistic skills and presents the basic elements on which to base the exploration of the metacognitive dimensions involved in verbal behavior. The validity was ascertained by means of Cronbach's Alpha Coefficient, including the values of each of the 6 sections; the correlations between variables were analyzed by the Pearson coefficient. Results: We observed that 64% of the sample corresponded to the female and 36% to the male gender, with predominant age ranging from 61 to 70 years. We verified adequate correlation between the variables according to the Pearson coefficient, and highly positive values according to Cronbach's Alpha. Conclusion: The use of the protocol is viable, with data demonstrating high reliability. The results evidenced high liability, which encourages the continuation process of its validation with Chilean aphasic population.

Relación entre el informe del cuidador sobre el habla espontánea del paciente y la Evaluación Breve de la Afasia / Relationship between the caregiver's report on the patient's spontaneous-speech and the Brief Aphasia Evaluation

RESUMEN Objetivo Estudiar la relación entre la percepción del cuidador sobre el deterioro en el habla espontánea del paciente, según un ítem de cuatro preguntas administradas mediante entrevista semiestructurada, y el desempeño del paciente en la Evaluación Breve de la Afasia (EBA). Método Se examinaron 102 pacientes diestros, con lesiones cerebrales focales de diferente tipo y localización. EBA es un instrumento válido y confiable para la medida de la afasia. Se correlacionó la percepción del cuidador con el ítem de habla espontánea, la puntuación total y los tres principales factores de EBA: el factor de Expresión, el de Comprensión y el Complementario. Se analizó la precisión (sensibilidad-especificidad) de la percepción del cuidador sobre el habla espontánea del paciente, respecto de la presencia o ausencia de trastorno, según el profesional, en el ítem de habla espontánea de EBA. Resultados La correlación estudiada fue satisfactoria, siendo mayor (superior al 80%) para los siguientes indicadores: el ítem de habla espontánea, el factor de Expresión y la puntuación total de la escala; la correlación fue un poco menor (superior al 70%) para el factor de Comprensión y el Complementario. Comparando dos puntos de corte que evaluaron la precisión en la percepción del cuidador, se observaron resultados satisfactorios en términos de sensibilidad y especificidad (>70%), con cocientes de probabilidad superiores a 3. Usando la mediana como punto de corte, se obtuvieron discriminaciones diagnósticas más satisfactorias. Conclusión Entrevistar al cuidador específicamente sobre el habla espontánea del paciente, en forma abreviada, proporciona información relevante para el diagnóstico de la afasia.

ABSTRACT Purpose To study the relationship between the caregiver's perception about the patient's impairment in spontaneous speech, according to an item of four questions administered by semi-structured interview, and the patient's performance in the Brief Aphasia Evaluation (BAE). Methods 102 right-handed patients with focal brain lesions of different types and location were examined. BAE is a valid and reliable instrument to assess aphasia. The caregiver's perception was correlated with the item of spontaneous speech, the total score and the three main factors of the BAE: Expression, Comprehension and Complementary factors. The precision (sensitivity/ specificity) about the caregiver's perception of the patient's spontaneous speech was analyzed with reference to the presence or absence of disorder, according to the professional, on the BAE item of spontaneous speech. Results The studied correlation was satisfactory, being greater (higher than 80%) for the following indicators: the item of spontaneous speech, the Expression factor and the total score of the scale; the correlation was a little smaller (higher than 70%) for the Comprehension and Complementary factors. Comparing two cut-off points that evaluated the precision of the caregiver's perception, satisfactory results were observed in terms of sensitivity and specificity (>70%) with likelihood ratios higher than three. By using the median as the cut-off point, more satisfactory diagnostic discriminations were obtained. Conclusion Interviewing the caregiver specifically on the patient's spontaneous speech, in an abbreviated form, provides relevant information for the aphasia diagnosis.

Charcot and aphasia: contributions of his assistants / Charcot e afasia: contribuições de seus assistentes

The ideas and concepts regarding language and its disorders have a longstanding history. However, it was possible to consider the 19th century as the period when the main milestones on the subject begun to be settled, with Paul Broca's and Carl Wernicke's pivotal findings. Albeit language disorders (aphasia) were not, apparently, his preferential interest, Charcot engaged himself in the issue, and after thorough studies delivered a series of lectures on this theme at the Salpêtrière Hospital, transcribed by two of his assistants, Charles Féré and Gaetano Rummo, and then published. Other three assistants, inspired in Charcot's teachings, Désiré Bernard, Gilbert Ballet and Pierre Marie, contributed independently with papers or books.The lectures and the contributions of those collaborators were partially incorporated in the Oeuvres Complètes published by Charcot.

As ideias e os conceitos sobre a linguagem e suas desordens possuemuma história de longa duração. Entretanto, é possível considerar o século XIX como o período no qual os principais marcos sobre o tema começaram a ser estabelecidos, com os achados fulcrais de Paul Broca e Carl Wernicke. Embora desordens da linguagem (afasia) não tenham sido, aparentemente, seu interesse predileto, Charcot se envolveu no assunto e, depois de aprofundados estudos, ministrou uma série de lições sobre o tema no Hospital da Salpêtrière, transcritas por dois de seus assistentes, Charles Féré e Gaetano Rummo, sendo publicados em seguida. Outros três assistentes, inspirados nos ensinamentos de Charcot, Désiré Bernard, Gilbert Ballet e Pierre Marie, contribuíram de modo independente com artigos ou livros. As lições e as contribuições desses colaboradores foram parcialmente incorporadas nas Oeuvres Complètes publicadas por Charcot.

Naming ability in patients with mild to moderate Alzheimer’s disease: what changes occur with the evolution of the disease?

OBJECTIVES: Naming deficit is a linguistic symptom that appears in the initial phase of Alzheimer’s disease, but the types of naming errors and the ways in which this deficit changes over the course of the disease are unclear. We analyzed the performance of patients with Alzheimer’s disease on naming tasks during the mild and moderate phases and verified how this linguistic skill deteriorates over the course of the disease. METHODS: A reduced version of the Boston Naming Test was administered to 30 patients with mild Alzheimer’s disease, 30 patients with moderate Alzheimer’s disease and 30 healthy controls. Errors were classified as verbal semantic paraphasia, verbal phonemic paraphasia, no response (pure anomia), circumlocution, unrelated verbal paraphasia, visual errors or intrusion errors. RESULTS: The patients with moderate Alzheimer’s disease had significantly fewer correct answers than did both the control group and the group with mild Alzheimer’s disease. With regard to the pattern of errors, verbal semantic paraphasia errors were the most frequent errors in all three groups. Additionally, as the disease severity increased, there was an increase in the number of no-response errors (pure anomia). The group with moderate Alzheimer’s disease demonstrated a greater incidence of visual errors and unrelated verbal paraphasias compared with the other two groups and presented a more variable pattern of errors. CONCLUSIONS: Performance on nominative tasks worsened as the disease progressed in terms of both the quantity and the type of errors encountered. This result reflects impairment at different levels of linguistic processing. .

Cross-cultural adaptation of the Western Aphasia Battery - Revised screening test to Brazilian Portuguese: a preliminary study / Adaptação transcultural para o Português Brasileiro do Teste de Rastreamento Western Aphasia Battery - Revised: um estudo preliminar

Purpose: The purpose of this study was to translate and cross-culturally adapt the Western Aphasia Battery - Revised (WAB-R) screening test, thus contributing to future applications of the instrument with Brazilian adults. Methods: The adaptation was based on a universalist perspective. The steps for conceptual, item, semantic and operational equivalence were strictly followed, resulting in a short version used in the pretest. The study participants were 30 individuals, between 18 to 89 years old; all were Brazilian speakers, with Portuguese as their first language. However, only 28 volunteers met the criteria for inclusion in the study. Two participants were excluded because they had low scores on the mini-mental state examination and were referred to geriatric assessment. Results: The short version of the WAB-R screening test, used in the pretest, allowed us to observe the behavior and language of the individuals during interactions, to collect impressions of overall communication, and to quantify communication ability by calculating the aphasia quotient and the language quotient, according to parameters of the original instrument. Conclusion: When adapting an instrument, it is important to maintain its original characteristics. However, the properties of measurement may not be in accordance with the psychometric properties of Brazilian culture. Therefore, we propose further analyses of the reliability and validation of the instrument in question in Brazil, which will occur by means of measurement and functional equivalence. .

Objetivo: A proposta deste estudo foi traduzir e adaptar transculturalmente o Teste de Rastreamento Western Aphasia Battery - Revised (WAB-R), colaborando para futura aplicação do instrumento em adultos brasileiros. Métodos: O roteiro de adaptação foi baseado na perspectiva universalista. As etapas de equivalência conceitual e de itens, semântica e operacional foram cumpridas rigorosamente, chegando-se a uma versão síntese usada no pré-teste. Participaram do estudo 30 indivíduos, dos 18 aos 89 anos, todos apresentando o Português Brasileiro como primeira língua. No entanto, apenas 28 voluntários preencheram os critérios de inclusão na pesquisa. Dois participantes foram excluídos, porque apresentaram pontuação baixa no Mini-Exame do Estado Mental, e foram encaminhados para avaliação geriátrica. Resultados: A versão síntese do Teste de Rastreamento WAB-R, usada no pré-teste, permitiu observar o comportamento e a linguagem dos sujeitos em interações, coletar impressões do quadro geral de comunicação e quantificar a habilidade comunicativa de acordo com o cálculo do quociente de afasia e do quociente de linguagem, com parâmetros do instrumento original. Conclusão: Ao se adaptar um instrumento, é importante manter suas características originais. Contudo, as propriedades de medidas podem não estar de acordo com as propriedades psicométricas da cultura brasileira. Sendo assim, propõe-se a análise da confiabilidade e validação no cenário brasileiro, que ocorrerão na equivalência de mensuração e funcional. .

Afasia: una perspectiva clínica / Aphasia: a clinical perspective

Language is a complex and dynamic system of conventional signs that results from the functioning of different brain areas located mainly in the left hemisphere. Clinical evaluation of aphasia implicates the examination of oral and written language. Aphasia is an acquired language disorders due to a brain damage that affect all modalities: oral expression, auditory comprehension, reading and writing. Various types of aphasias can be induced, each with well defined clinical characteristics that can be correlated with specific areas of the brain. The prognosis depends mainly on the etiology, size of the lesion, type of aphasia and its severity. Treatment objectives include: satisfying the communicational needs of the patient, and achieving psychosocial adaptation of the subject and his family. Both objectives improve the quality of life of our patients...

The evaluation of swallowing in patients with spinocerebellar ataxia and oropharyngeal dysphagia: A comparison study of videofluoroscopic and sonar doppler

Introduction: Spinocerebellar ataxia (SCA) is a degenerative disease that can cause loss of coordination of voluntary muscle movement such as that required for swallowing. Aims: The purposes of this cross-sectional and comparative case study were: (1) to assess the severity of dysphagia through a videofluoroscopic swallow study, and (2) to compare differences in frequency, intensity, and duration of sound waves produced during swallowing in normal and SCA patients by using sonar Doppler. Method: During swallow evaluation using videofluoroscopy, a sonar Doppler transducer was placed on the right side of the neck, at the lateral edge of the trachea, just below the cricoid cartilage to capture the sounds of swallowing in 30 SCA patients and 30 controls. Result: The prevalence in the dynamic evaluation of swallowing videofluoroscopy was by changes in the oral phase of swallowing. The analysis of variance of the averages found in each variable - frequency, intensity and duration of swallowing - shows there was a significant correlation when compared to the healthy individual curve. Conclusion: The study demonstrates the prevalence of oral dysphagia observed in dynamic videofluoroscopic swallow evaluation. In patients with SCA, the mean initial frequency (IF), initial intensity (II), and final intensity (FI) were higher and the time (T) and peak frequency (PF) were lower, demonstrating a pattern of cricopharyngeal opening very close to that found in normal populations...

Análise do reconhecimento das figuras do Teste MT Beta-86 modificado para uma adaptação: descrição e discussão de aspectos metodológicos / Analysis of figure recognition on the modified MT Beta-86 Test for adaptation: description and discussion of methodological aspects

OBJETIVO: Analisar o reconhecimento das figuras do Teste MT Beta-86 modificado, descrever e discutir aspectos metodológicos da adaptação desse instrumento de avaliação da linguagem. MÉTODOS: O estudo foi dividido em duas partes. Na primeira, participaram 61 indivíduos com escolaridade superior a 9 anos. Solicitou-se nomeação de 266 estímulos visuais e verificou-se a concordância da nomeação das figuras entre os participantes. Para a concordância de respostas, utilizou-se o teste de Cochran, com nível de significância de 5%. Em seguida, alguns estímulos visuais foram redesenhados, e as imagens foram substituídas. As imagens passaram pela segunda parte do estudo, da qual participaram 110 indivíduos divididos em 4 faixas de escolaridade (A: 1 a 4 anos; B: 5 a 8 anos; C: 9 a 11 anos e D: acima de 12 anos), de ambos os sexos e idades entre 18 e 75 anos. Foram considerados adequados para serem utilizados na avaliação de linguagem os estímulos com índice de concordância de, no mínimo, 70%. RESULTADOS: Na parte A do estudo, a partir do índice de concordância de nomeação das figuras, foram escolhidas as consideradas apropriadas para fazer parte do teste em sua versão em adaptação. A segunda parte demonstrou que todas as figuras selecionadas apresentaram concordância de resposta acima de 70%. CONCLUSÃO: Identificaram-se quais figuras do Teste MT Beta-86 modificado poderão continuar presentes na próxima versão do instrumento e, por meio da análise do baixo reconhecimento populacional, verificaram-se quais pranchas deverão ser substituídas e quais poderão compor a nova versão do teste.

PURPOSE: The purpose of this study was to analyze the recognition of figures from the modified MT Beta-86 test for subsequent refinement and adaptation of this language assessment instrument. METHODS: This study was organized into two parts. The first part of the study involved 61 subjects with educational level higher than nine years. Naming of 266 visual stimuli was elicited and concordance among participants on figure naming was also determined. Concordance of responses was assessed using Cochrane's test at a 5% level of significance. Some visual stimuli were subsequently re-designed and images were replaced. The second part of this study involved the re-testing of the new images among 110 individuals ranging in age from 18 to 75 years of both genders, stratified into four educational bands (A: 1 - 4 years; B: 5 - 8 years; C: 9 - 11 years; and D: more than 12 years). Stimuli with concordance level of 70% or higher were considered adequate. RESULTS: In part A of the study, from the index of agreement of naming, the figures considered suitable for inclusion in the adapted version were selected. In part B, all the figures had a response concordance level over 70%. CONCLUSION: Figures in the Modified MT Beta-86 test suitable for retention in the new version of the instrument were identified. Analysis of low sample recognition was used to identify boards for replacement, and those for retention, in the new version of the test.

Trastornos del lenguaje en el adulto / Language disorders in adults

El presente trabajo tiene por objetivo principal describir los trastornos del lenguaje en el adulto a consecuencia de un daño cerebral. Las alteraciones del lenguaje oral se abordarán considerando los siguientes tópicos: Algunos conceptos lingüísticos básicos para describir con exactitud las alteraciones del lenguaje; el sistema funcional del lenguaje en el que participan áreas persilvianas, hemisferio derecho y zonas prefrontales; las afasias que son un trastorno parcial o total del lenguaje; los pacientes afásicos considerando sus antecedentes clínicos, la actitud frente al defecto, el deterioro intelectual y otros defectos asociados; el tratamiento de las afasias que tiene por objetivo que el paciente logre una comunicación funcional y una adaptación psicosocial en relación a la alteración de lenguaje y por último, los trastornos del discurso que comprometen especialmente su contenido y su uso. En relación a las alteraciones del lenguaje lectoescrito se describirán los diferentes tipos de agrafias y alexias. Finalmente, cabe señalar dos aspectos, el primero, es que además de las afasias existen otros trastornos del lenguaje y el segundo, es que la evaluación del lenguaje es fundamental para el manejo y la rehabilitación del paciente.

The main purpose of the current review is to describe the language disorders in adult as a consequence of brain damage. The oral language disorders will be approached regarding the following topics: some basic linguistic concepts to describe language disturbances accurately; the functional language system involving perisylvian areas, right hemisphere and prefrontal areas; aphasia that represent a total or partial language impairment; the patient with aphasia, regarding their clinical background, their attitude towards the alteration, the cognitive impairment and other associated disorders; the aphasia treatment which has for purposes to achieve a functional communication and psychological and social adaptation considering their language impairment and, at last, the discourse impairment which affects their use and content. Regarding the reading and writing impairment, agraphia and alexia types will be described. Finally, it is important to mention two aspects: first, besides aphasia there are other language disorders and, second, language assessment is essential to the management and rehabilitation of the patient.

Correlation between brain injury and dysphagia in adult patients with stroke

Introduction: In the literature, the incidence of oropharyngeal dysphagia in patients with cerebrovascular accident (AVE) ranges 20-90%. Some studies correlate the location of a stroke with dysphagia, while others do not. Objective: To correlate brain injury with dysphagia in patients with stroke in relation to the type and location of stroke. Method: A prospective study conducted at the Hospital de Clinicas with 30 stroke patients: 18 women and 12 men. All patients underwent clinical evaluation and swallowing nasolaryngofibroscopy (FEES®), and were divided based on the location of the injury: cerebral cortex, cerebellar cortex, subcortical areas, and type: hemorrhagic or transient ischemic. Results: Of the 30 patients, 18 had ischemic stroke, 10 had hemorrhagic stroke, and 2 had transient stroke. Regarding the location, 10 lesions were in the cerebral cortex, 3 were in the cerebral and cerebellar cortices, 3 were in the cerebral cortex and subcortical areas, and 3 were in the cerebral and cerebellar cortices and subcortical areas. Cerebral cortex and subcortical area ischemic strokes predominated in the clinical evaluation of dysphagia. In FEES®, decreased laryngeal sensitivity persisted following cerebral cortex and ischemic strokes. Waste in the pharyngeal recesses associated with epiglottic valleculae predominated in the piriform cortex in all lesion areas and in ischemic stroke. A patient with damage to the cerebral and cerebellar cortices from an ischemic stroke exhibited laryngeal penetration and tracheal aspiration of liquid and honey. Conclusion: Dysphagia was prevalent when a lesion was located in the cerebral cortex and was of the ischemic type...

Aphasia and herpes virus encephalitis: a case study / Afasia e herpes vírus: estudo de caso

CONTEXT: Meningoencephalitis early in life, of any etiology, is a risk factor for development of subsequent sequelae, which may be of physical, psychiatric, behavioral or cognitive origin. Anomia is a language abnormality frequently found in such cases, and other language deficits are rarely described. The aim of this study was to describe the cognitive and linguistic manifestations following a case of herpetic meningoencephalitis in a 13-year-old patient with eight years of schooling. CASE REPORT: The patient underwent a speech-language audiology assessment nine months after the neurological diagnosis. The battery of tests included the Montreal-Toulouse Language Assessment test protocol (MT Beta-86, modified), the description from the Cookie Theft task of the Boston Diagnostic Aphasia Examination (BDAE), an informal assessment of the patient's logical and mathematical reasoning, and the neuropsychological subtests from the WAIS-III scale, which assess working memory. The patient presented mixed aphasia, impairment of short-term memory and working memory, and dyscalculia. This case also presented severe cognitive and linguistic deficits. Prompt diagnosis is crucial, in order to enable timely treatment and rehabilitation of this neurological infection and minimize the cognitive deficits caused by the disease.

CONTEXTO: Meningoencefalite em idade precoce, de qualquer etiologia, é fator de risco para o desenvolvimento de sequelas posteriores, que podem ser de origem física, psíquica, comportamental ou cognitiva. Anomia é uma manifestação linguística frequente nesses casos e outras alterações de linguagem raramente são descritas. O objetivo do estudo foi descrever as manifestações linguísticas e cognitivas pós-meningoencefalite herpética de um paciente com 13 anos de idade e oito anos de escolaridade. RELATO DE CASO: O paciente passou por avaliação fonoaudiológica nove meses após o diagnóstico neurológico. A bateria de avaliação incluiu o Protocolo de Avaliação de Linguagem Montreal Toulouse (MT Beta-86 modificado), a descrição da prancha Roubo dos Biscoitos do Teste de Boston para o diagnóstico da afasia, avaliação informal do raciocínio lógico-matemático e os subtestes neuropsicológicos da escala WAIS-III que avaliam a memória de trabalho. O paciente apresentou afasia mista, alteração da memória de curto prazo e da memória de trabalho e discalculia. Apresentou também alterações cognitivas e linguísticas graves. O diagnóstico precoce tem fundamental importância para o tratamento oportuno e a reabilitação dessa infecção neurológica e também para minimizar as alterações cognitivas causadas pela doença.

Reversible Dysphasia and Statins

This paper presents a case of reversible dysphasia occurring in a patient prescribed atorvastatin in combination with indapamide. A milder dysphasia recurred with the prescription of rosuvastatin and was documented on clinical examination. This resolved following cessation of rosuvastatin. The case highlights both a need for a wider understanding of potential drug interactions through the CYP 450 system and for an increased awareness, questioning and reporting of drug side-effects.

A topographic study on the evaluation of speech and language in the acute phase of a first stroke / Um estudo topográfico da avaliação de fala e linguagem na fase aguda de um primeiro infarto cerebral

Evaluation of speech and language may help in localization of site and extension of brain lesions, particularly in the absence of other neurological signs or radiologically defined injuries. OBJECTIVE: To verify what language tasks are best correlated to which brain regions, in order to develop a test for neurologists in emergency settings. METHOD: Thirty-seven adult first-stroke patients were submitted to cognitive and language tests, and then paired with thirty-seven healthy controls. Patients underwent CT and/or MRI for topographic correlation with test results (p<0.05). RESULTS: All tests were able to distinguish patients from controls, but only word/sentence repetition, naming, ideomotor praxis and, non-significantly, comprehension and counting 1-20 predicted left hemisphere lesions. Repetition was related to perisylvian structures, comprehension to the posterior portion of the middle cerebral artery territory, and fluency to frontal lesions, while naming was accurate only for lesion side. CONCLUSION: Language and cognitive tasks can help in the localization of acute stroke lesions.

Avaliação de fala e linguagem pode ajudar na localização do sítio e da extensão de lesões cerebrais, especialmente quando ausentes outros sinais neurológicos ou radiológicos. OBJETIVO: Verificar quais tarefas linguísticas se correlacionam melhor com quais regiões cerebrais, a fim de desenvolver um teste para uso pelos neurologistas em emergências. MÉTODO: 37 pacientes e 37 controles pareados passaram por avaliação linguístico-cognitiva. Pacientes foram submetidos a TC e/ou RM para correlação topográfica com os resultados da avaliação (p<0,05). RESULTADOS: Todos os testes diferenciaram pacientes de controles, mas apenas os de repetição de palavras/sentenças, nomeação, praxia ideomotora e, de forma não-significativa, compreensão e contagem 1-20 puderam predizer lesões no hemisfério esquerdo. Os testes de repetição estavam relacionados com estruturas perisylvianas, compreensão com a porção posterior do território da artéria cerebral média, e fluência com regiões frontais, enquanto os de nomeação localizavam apenas o lado das lesões. CONCLUSÃO: Testes linguístico-cognitivos podem ajudar a localizar infartos cerebrais agudos.

Aplicação do teste M1-Alpha em sujeitos normais com baixa escolaridade: estudo piloto / M1-Alpha test in normal subjects with low educational Level: a pilot study

OBJETIVO: Verificar o desempenho de sujeitos normais com baixa escolaridade no teste M1-Alpha e obter parâmetros que possam ser utilizados na avaliação clínica de pacientes afásicos com baixa escolaridade, expostos a este teste. MÉTODOS: Foram selecionados 30 sujeitos normais de baixa escolaridade (um a quatro anos de estudo), com idade superior a 18 anos e inferior a 60 anos, sendo 15 do gênero masculino e 15 do gênero feminino. Todos foram submetidos à aplicação do teste M1-Alpha, que comporta entrevista semidirigida e provas controladas. Todas as respostas corretas receberam um ponto. Os dados foram submetidos a tratamento estatístico. RESULTADOS: Foi verificado um maior número de erros, bem como uma maior variabilidade nas respostas, em tarefas de escrita copiada, ditado, leitura em voz alta e compreensão escrita. CONCLUSÃO: A baixa escolaridade influencia o desempenho dos indivíduos nas tarefas de escrita copiada, ditado, leitura em voz alta e compreensão escrita. Foi possível obter dados de referência, que poderão ser utilizados na aplicação clínica do teste M1-Alpha em pacientes com baixa escolaridade.

PURPOSE: To determine the performance of normal subjects with low educational level on the M1-Alpha test, and to obtain parameters for potential use in the clinical evaluation of aphasic patients with low educational level. METHODS: Participants were 30 normal subjects with low educational level (one to four years of schooling), 15 male and 15 female, with ages over 18 years and below 60 years. All subjects were submitted to the M1-Alpha test, which comprehends semi-directed interview and controlled tasks. One point was given for every correct answer. Data were statistically analyzed. RESULTS: It was verified a higher number of errors, as well as greater variability of responses, in the following tasks: copying, writing to dictation, reading comprehension, and reading aloud. CONCLUSION: Low educational level influences the performance of subjects on the tasks copying, writing to dictation, reading aloud, and reading comprehension. It was possible to obtain reference data for potential clinical application of the M1-Alpha test in patients with low educational level.
