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.

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)

Aphasia assessment: impact of material on naming performance / Avaliação da afasia: impacto do material no desempenho da nomeação

ABSTRACT Background: Naming and lexical retrieval difficulties are common symptoms of aphasia. Naming abilities are usually evaluated by means of real objects or pictures or line drawings that are printed. Objective: The aim of this study was to investigate whether the ability to name objects among individuals with aphasia is influenced by the dimensions of the visual stimuli and to understand whether the order of presentation of the stimuli, number of years of education and length of time post-onset are involved in the success of naming. Methods: The naming abilities of healthy controls and patients with acute or chronic aphasia due to stroke were assessed through presentation of two sets of 24 stimuli consisting of real objects and color photographs of the same objects presented on a screen. The results obtained under these two conditions were compared by means of within-subject paired ANOVA, controlling for presentation order. Results: 40 patients (62.4 ± 17.3 years old; 70% females; mean education level of 8.5 ± 5.3 years; and 60% evaluated within the first eight days after stroke) and 50 controls that were age, gender and education-matched were included. Object naming was significantly better than naming color photographs among the patients (p = 0.001), but no differences were observed among the controls. Age, education, length of time post-onset and presentation sequence did not have any impact on naming performance. Conclusion: These results suggest that use of digital color photographs for naming objects in assessment of aphasia may be associated with lower naming performance, compared with use of real objects. This needs to be taken into account when different forms of stimuli are presented in sequential aphasia evaluations.

RESUMO Antecedentes: As dificuldades de nomeação e de evocação lexical são sintomas comuns de afasia. A nomeação é geralmente avaliada por objetos reais, imagens ou desenhos de contorno, impressos. Objetivo: Este estudo visa investigar se a capacidade de nomear objetos em pessoas com afasia é influenciada pelas dimensões dos estímulos visuais e compreender se a ordem de apresentação dos estímulos, os anos de escolaridade e o tempo de evolução estão envolvidos no sucesso da nomeação. Métodos: A nomeação de pessoas saudáveis e pessoas com afasia, em fase aguda ou crónica, por AVC foi avaliada com dois conjuntos de 24 estímulos, objetos reais e fotografias a cores, dos mesmos objetos, apresentadas num ecrã. Os resultados obtidos nas duas condições foram comparados por uma ANOVA para amostras emparelhadas, controlando para a ordem de apresentação. Resultados: Foram incluídos 40 sujeitos com afasia (62,4±17,3 anos de idade, 70% mulheres, com uma escolaridade média de 8,5±5,3 anos, 60% avaliados nos primeiros 8 dias após o acidente vascular cerebral) e um grupo de controlo de 50 pessoas saudáveis, emparelhadas para a idade, sexo e escolaridade. A nomeação de objetos foi significativamente melhor do que a nomeação de fotografias a cores (p=.001), mas isso não se verificou nos controles. A idade, a escolaridade, o tempo de evolução e a sequência de apresentação não tiveram impacto na nomeação dos dois tipos de estímulos. Conclusão: Estes resultados sugerem que a utilização de fotografias digitais a cores para avaliar a nomeação de objetos na afasia pode ser associada a um pior desempenho quando comparada com objetos reais. Isto deve ser tido em conta quando são apresentadas diferentes formas de estímulos nas reavaliações.

Post-stroke aphasia in famous writers: when Neurology left geniuses speechless / Afasia pós-AVC em escritores famosos: quando a Neurologia deixou gênios sem palavras

ABSTRACT Aphasia is a frequent and devastating stroke complication that does not spare even great writers. In these cases, not only one of the highest cognitive functions is suddenly lost but also the act of bringing beauty into the world. Herein, we discuss the case of three writers who had to abandon their art compulsorily due to a cerebrovascular disease: Charles Baudelaire, Ralph Waldo Emerson, and Stendhal. They were magnificent writers, united by excellence in literature and an inevitable destiny that restricted their art to just a few words. They are also examples of the proximity of Neurology to Art, History, and Literature.

RESUMO A afasia é uma complicação frequente e devastadora do acidente vascular cerebral (AVC), que não poupa nem mesmo os grandes escritores. Nesses casos, de repente, perde-se não apenas uma das funções cognitivas mais importantes, mas o ato de colocar a beleza no mundo. Discutimos o caso de três escritores que precisaram abandonar sua arte compulsoriamente devido a uma doença cerebrovascular: Charles Baudelaire, Ralph Waldo Emerson e Stendhal. Todos eles foram escritores magníficos, unidos pela excelência em literatura e por um destino inevitável que restringia sua arte a apenas algumas palavras. Eles também são exemplos da proximidade da Neurologia com a Arte, a História e a Literatura.

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.

Reabilitação pós-AVC: identificação de sinais e sintomas fonoaudiológicos por enfermeiros e médicos da Atenção Primária à Saúde / Post-stroke rehabilitation: identification of speech-language disorders signs and symptoms by physicians and nurses in Primary Health Care

RESUMO Objetivo O Acidente Vascular Cerebral (AVC) é um agravo comum para a população e um problema para a saúde pública global em termos de mortalidade, deficiência e demanda de custos. O objetivo deste estudo é verificar quais grupos de comorbidades ligados aos distúrbios fonoaudiológicos são identificados por médicos e enfermeiros das equipes de Estratégia de Saúde da Família (ESF) para encaminhamento à reabilitação fonoaudiológica e continuidade do cuidado de pacientes pós-AVC nas Atenções Primária e Secundária à Saúde (APS). Método Participaram 22 médicos e enfermeiros das equipes de ESF apoiadas pelo Núcleo de Apoio à Saúde da Família, no sul do Brasil. Um questionário desenvolvido para este estudo foi respondido, explorando variáveis sociodemográficas, histórico de formação, atuação profissional e condutas ao paciente com AVC. Análise descritiva dos dados (frequências absoluta e relativa) foi realizada no Software SPSS 22. Resultados Dos entrevistados, 77,3% encaminham pacientes pós-AVC para fisioterapia e 54,5%, para reabilitação fonoaudiológica. Nenhum profissional realiza encaminhamento por sequelas cognitivas de compreensão; 90,0% encaminham por distúrbios de linguagem expressiva na fala. Para alterações do sistema estomatognático, 80,0% dos médicos não encaminham para fonoaudiólogo e 83,3% dos enfermeiros o fazem. Conclusão Os profissionais demonstraram dificuldade em identificar distúrbios fonoaudiológicos ligados à cognição e ao sistema estomatognático, não encaminhando para reabilitação fonoaudiológica nas Atenções Primária e Secundária à Saúde. Os resultados apontam para a necessidade de ações que auxiliem no processo de educação permanente e melhorem o conhecimento das equipes de APS, para que as sequelas fonoaudiológicas sejam devidamente identificadas e encaminhadas para reabilitação.

ABSTRACT Purpose Stroke is a common disease for people and a global public health concern in terms of mortality, disability, and cost demand. This study aims to assess which groups of comorbidities related to speech-language disorders are identified by physicians and nurses of the Family Health Strategy (FHS) as to be referred to post-stroke speech-language rehabilitation at Primary and Secondary Health Care. Methods Twenty-two physicians and nurses, from the FHS supported by the Family Health Support Center in southern Brazil, answered a questionnaire developed for this study, exploring socio-demographic variables, education background, professional performance and conduct to post-stroke patients. A descriptive data analysis (absolute and relative frequencies) was performed in SPSS Software 22. Results Among the participants, 77.3% refer post-stroke patients to physiotherapy and 54.5% to speech-language rehabilitation. None refer to patients to treatment due to cognitive comprehension sequelae; 90.0% refer for significant speech-language disorders. In case of changes in the stomatognathic system, 80.0% of physicians do not refer to speech-language pathologists, and 83.3% of nurses usually do. Conclusion The professionals showed difficulty in identifying speech-language pathological signs and symptoms related to cognition and the stomatognathic system, not referring to speech-language rehabilitation at primary or secondary health care. The results highlight the importance of continuing education and improvement of the knowledge of the primary health care teams, so that speech-language sequelae are properly identified and sent for rehabilitation.

Caracterização das afasias na hemorragia subaracnóidea aneurismática / Characterization of aphasia in aneurysmal subarachnoid hemorrhage

RESUMO Objetivo Caracterizar o perfil dos quadros afásicos determinados pela hemorragia subaracnóidea aneurismática (HSA) da artéria cerebral média esquerda. Método Estudo analítico, retrospectivo, transversal, tendo como banco de dados as avaliações cognitivas de 193 pacientes do Hospital da Restauração com HSA aneurismática no período de março de 2007 a novembro de 2009. Destes, foram selecionados 26 pacientes com HSA em território da ACM-E, confirmada por angiografia digital. Os quadros afásicos foram classificados através do desempenho da linguagem dos pacientes através do Protocolo Montreal Toulose - Versão Alpha e a tarefa de fluência verbal da bateria CERAD. A pesquisa foi realizada no período de junho a agosto de 2015. Resultados Foi identificado comprometimento da linguagem e fluência verbal nos pacientes com HSA em território de ACM-E quando comparados com a população controle (50 indivíduos). Dos 26 pacientes com HSA, 11 apresentaram quadros afásicos ainda no período pré-operatório. Conclusão Os resultados da pesquisa corroboram com a literatura, mostrando que o quadro da HSA promove comprometimentos cognitivos ainda na fase pré-operatória para oclusão de aneurisma. Tendo em vista os aspectos observados, os quadros afásicos predominantes caracterizam afasia de compreensão por sequelas nas áreas cerebrais posteriores.

ABSTRACT Purpose Characterize the profile of aphasic syndromes determined by aneurysmal subarachnoid hemorrhage (aSAH) of the left middle cerebral artery (LMCA). Methods An analytical, retrospective, cross-sectional study was conducted using a database of cognitive assessments of 193 patients with aSAH admitted to Hospital da Restauração between March 2007 and November 2009. Of these, a total of 26 patients with aSAH in the LMCA territory confirmed by digital angiography were selected. Aphasia was assessed through the Montreal-Toulouse Language Assessment Alpha Version Protocol (Alpha Version) and the CERAD Neuropsychological Test Battery (Verbal fluency). Results Language and verbal fluency impairments were identified in patients with aSAH in the LMCA territory when compared with the control population (50 individuals). Of the 26 patients with aSAH, 11 presented aphasic characteristics preoperatively. Conclusion The results of this research corroborate the literature, showing that the aSAH frame causes cognitive impairments even in the preoperative phase for aneurysm occlusion. Considering the observed aspects, the predominant aphasic syndromes characterize comprehension aphasia due to sequels in the posterior cerebral artery territory.

Características neuropsicológicas y neurofisiológicas de los distintos tipos de afasias / Neuropsychological and neurophysiological characteristics of the different types of aphasias

Las afasias se entienden como una pérdida de destrezas en el lenguaje, tanto hablado como escrito, y en la comprensión de contenidos. La afasia comúnmente es consecuencia de accidentes cerebrovasculares. A pesar de que los diversos tipos de afasias se correlacionan con áreas encefálicas especializadas para la comunicación, muchas poblaciones con lesiones cerebrales demuestran tener patologías del habla y del lenguaje no especificadas. Considerando las peculiaridades neuropsicológicas y neurofisiológicas que poseen las afasias, el presente estudio busca profundizar en las diferencias encontradas entre cada cuadro clínico de afasia, revisándose de este modo, los principales aportes contemporáneos para explicar las alteraciones lecto-escritoras producidas por la afasia.

Aphasias are understood like a loss of language skills, both spoken and written, and in the understanding of contents. Aphasia is commonly a consequence of stroke. Although various types of aphasia correlate with specialized brain areas for communication, many populations with traumatic brain injury shows unspecified speech and language pathologies. Considering the neuropsychological and neurophysiological peculiarities of aphasias, this research seeks to deepen the differences found between each clinical symptoms of aphasia, revising in this pathway, the main contemporary contributions to explain the reading-writing alterations produced by aphasia

Limb apraxia in aphasic patients / Apraxia de membros em indivíduos afásicos

ABSTRACT Limb apraxia is usually associated with left cerebral hemisphere damage, with numerous case studies involving aphasic patients. The aim of this study was to verify the occurrence of limb apraxia in aphasic patients and analyze its nature. This study involved 44 healthy volunteers and 28 aphasic patients matched for age and education. AH participants were assessed using a limb apraxia battery comprising subtests evaluating lexical-semantic aspects related to the comprehension/production of gestures as well as motor movements. Aphasics had worse performances on many tasks related to conceptual components of gestures. The difficulty found on the imitation of dynamic gesture tasks also indicated that there were specific motor difficulties in gesture planning. These results reinforce the importance of conducting limb apraxia assessment in aphasic patients and also highlight pantomime difficulties as a good predictor for semantic disturbances.

RESUMO A apraxia de membros está frequentemente associada com lesões do hemisfério esquerdo, com inúmeros casos de pacientes afásicos. O objetivo deste estudo foi verificar a ocorrência da apraxia de membros em pacientes afásicos bem como a natureza desse distúrbio. O estudo foi realizado com 28 indivíduos afásicos e 44 controles pareados segundo a idade e a escolaridade. Todos os participantes foram avaliados com uma extensa bateria de apraxia de membros, consistindo de subtestes que avaliaram a compreensão e a produção dos aspectos léxico-semânticos relacionados aos gestos bem como produção motora propriamente dita. Os pacientes afásicos apresentaram dificuldades em tarefas envolvendo aspectos conceptuais da produção gestual. A dificuldade encontrada na imitação de gestos dinâmicos também indicou déficits no processamento gestual independente do déficit conceptual observado nestes pacientes. Esses resultados reforçam a importância da avaliação da apraxia de membros e apontam para a dificuldade de realização de pantomimas como indicativa de déficits semânticos.

Non-invasive brain stimulation and computational models in post-stroke aphasic patients: single session of transcranial magnetic stimulation and transcranial direct current stimulation. A randomized clinical trial

ABSTRACT CONTEXT AND OBJECTIVE: Patients undergoing the same neuromodulation protocol may present different responses. Computational models may help in understanding such differences. The aims of this study were, firstly, to compare the performance of aphasic patients in naming tasks before and after one session of transcranial direct current stimulation (tDCS), transcranial magnetic stimulation (TMS) and sham, and analyze the results between these neuromodulation techniques; and secondly, through computational model on the cortex and surrounding tissues, to assess current flow distribution and responses among patients who received tDCS and presented different levels of results from naming tasks. DESIGN AND SETTING: Prospective, descriptive, qualitative and quantitative, double blind, randomized and placebo-controlled study conducted at Faculdade de Ciências Médicas da Santa Casa de São Paulo. METHODS: Patients with aphasia received one session of tDCS, TMS or sham stimulation. The time taken to name pictures and the response time were evaluated before and after neuromodulation. Selected patients from the first intervention underwent a computational model stimulation procedure that simulated tDCS. RESULTS: The results did not indicate any statistically significant differences from before to after the stimulation.The computational models showed different current flow distributions. CONCLUSIONS: The present study did not show any statistically significant difference between tDCS, TMS and sham stimulation regarding naming tasks. The patients'responses to the computational model showed different patterns of current distribution.

Incidencia poblacional, características epidemiológicas y desenlace funcional de pacientes con ataque cerebrovascular isquémico y afasia / Incidence of aphasia in patients experiencing an ischemic stroke

Background: Sequelae after a stroke are common and may lead to disability. Aphasia - defined as an acquired language disturbance - can cause important limitations in quality of life. Aim: To describe the epidemiological features of patients who had an aphasia after a first episode of ischemic stroke and their functional outcome at six months. Material and Methods: Review of a database of a population study on the incidence, 30-day case fatality rate, and prognosis of stroke performed in a northern Chilean city between 2000 and 2002. Results: Aphasia was diagnosed in 28 of 142 patients in whom the disorder was sought (20%). The projected incidence rate in the city where the study was carried out is 7.06 per 100,000 inhabitants. The mean age of these 28 patients was 66 ± 20 years and 53% were women. The main risk factor for stroke was hypertension in 62%. The etiology of stroke was undetermined in 64% of these patients. Partial anterior circulation infarction was the most common stroke location in 61%. Conclusions: Twenty percent of patients with a first episode of ischemic stroke have aphasia

Degeneración corticobasal: reporte de un caso / Corticobasal degeneration: a case report

Se presenta un caso de Degeneración Corticobasal en una paciente chilena de 48 años de edad. La evolución clínica fue progresiva, con parkinsonismo (rigidez, acinesia, alteraciones posturales, disartria), deterioro cognitivo, apraxia del vestir, apraxia constructiva e hipomimia. Además, la paciente presentaba afasia no fluente. Adicionalmente, fue diagnosticada con Síndrome Depresivo Crónico (SDC) y Trombosis Venosa Profunda (TVP) de la extremidad inferior izquierda. Se han descrito varios tipos de enfermedades neurodegenerativas en las últimas décadas, las cuales cumplen con distintas características patológicas y clínicas. Sin embargo, la diferenciación de estas, en la práctica, es compleja y se necesita de una apreciación clínica entrenada, evaluaciones clínicas detalladas, neuroimágenes y estudios de laboratorio para lograr llegar a un diagnóstico adecuado. Dentro de las principales enfermedades neurodegenerativas que se presentan con parkinsonismo encontramos las llamadas “taupatías”, que son la Degeneración Corticobasal (DCB) y la Parálisis Supranuclear Progresiva*(PSP)...

A case study of corticobasal degeneration in a Chilean 48 year old female patient is reported. The clinical course was progressive and included Parkinsonism (rigidity, akinesia, postural abnormalities, dysarthria), cognitive impairment, dressing apraxia, constructive apraxia and hypomimia. In addition, the patienth ad non Mfluent aphasia. Also, the patient was diagnosed with Chronic Depressive Syndrome and Deep Venous Thrombosis (DVT) of the left lower extremity. In recent decades, several types of neurodegenerative diseases* have been described. These diseases have different clinical and pathologic features. However, in practice, it is difficult to differentiate them from one another and, to reach an accurate diagnosis, advanced medical skills, detailed clinical evaluations of neuroimaging and laboratory studies are needed. “Tauopathies”, which are Corticobasal Degeneration (CBD) and Progressive Supranuclear Palsy (PSP) are among the major neurodegenerative diseases occurring with Parkinsonism...

Cognitive deficits in post-stroke aphasia / Déficits cognitivos na afasia pós-AVE

The assessment of aphasics’ cognitive performance is challenging and such patients are generally excluded from studies that describe cognitive deficits after stroke. We evaluated aphasics’ performance in cognitive tasks compared to non-aphasic subjects. A sample of 47 patients (21 aphasics, 17 non-aphasics with left hemisphere lesions and 9 non-aphasics with right hemisphere lesions) performed cognitive tasks (attention, verbal and visual memory, executive functions, visuospatial skills and praxis). Aphasic patients performed poorer than all non-aphasics in Digit Span (p < 0.001), Clock-Drawing Test (p = 0.006), Verbal memory (p = 0.002), Visual Memory (p < 0.01), Verbal Fluency (p < 0.001), and Gesture Praxis (p < 0.001). Aphasia severity correlated with performance in Trail Making test part B (p = 0.004), Digit Span forward (p < 0.001) and backwards (p = 0.011), and Gesture Praxis (p = 0.002). Aphasia is accompanied by deficits not always easy to be evaluated by cognitive tests due to speech production and motor impairments. Assessment of cognitive functions in aphasics might contribute to optimize therapeutic intervention.

A avaliação cognitiva de afásicos é difícil e tais pacientes são frequentemente excluídos dos estudos que descrevem déficits cognitivos pós-AVC. Avaliamos o desempenho de afásicos em tarefas cognitivas comparados a não-afásicos. Um grupo de 47 indivíduos (21 afásicos, 17 não-afásicos com lesão à E e 9 não-afásicos com lesão à D) realizou testes cognitivos (atenção, memória verbal e visual, funções executivas, habilidades visoespaciais e praxias). Afásicos apresentaram pior desempenho do que não-afásicos em Extensão de Dígitos (p < 0,001), Desenho do Relógio (p = 0,006), Memória Verbal (p = 0,002), Memória Visual (p < 0,01), Fluência Verbal (p < 0,001) e Praxias Gestuais (p < 0,001). A gravidade da afasia correlacionou-se com o desempenho no Teste de Trilhas parte B (p = 0,004), Extensão de Dígitos direta (p < 0,001) e inversa (p = 0,01), e Praxias Gestuais (p = 0,002). Afasia é acompanhada por déficits difíceis de ser avaliados devido às deficiências de expressão e motoras. A avaliação das funções cognitivas em afásicos pode otimizar a intervenção terapêutica.

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. .

Community Integration and Quality of Life in Aphasia after Stroke

PURPOSE: To examine community integration and contributing factors in people with aphasia (PWA) following stroke and to investigate the relationship between community integration and quality of life (QOL). MATERIALS AND METHODS: Thirty PWA and 42 age-and education-matched control subjects were involved. Main variables were as follows: socioeconomic status, mobility, and activity of daily living (ADL) (Modified Barthel Index), language function [Frenchay Aphasia Screening Test (FAST)], depression [Geriatric Depression Scale (GDS)], Community Integration Questionnaire (CIQ) and Stroke and Aphasia Quality of Life Scale-39 (SAQOL-39). Differences between aphasia and control groups and factors affecting community integration and QOL were analyzed. RESULTS: Home and social integration and productive activity were significantly decreased in the aphasia group compared to the control group; 8.5 and 18.3 points in total CIQ score, respectively. Amount of time spent outside the home and frequency of social contact were also significantly reduced in the aphasia group. Total mean score on the SAQOL-39 was 2.75+/-0.80 points and was significantly correlated with economic status, gait performance, ADL, depressive mood, and social domain score on the CIQ. Depression score measured by GDS was the single most important factor for the prediction of QOL, but the FAST score was significantly correlated only with the communication domain of the SAQOL-39. CONCLUSION: Community activities of PWA were very limited, and depression was highly associated with decreased community integration and QOL. Enhancing social participation and reducing emotional distress should be emphasized for rehabilitation of PWA.

Audiological findings in aphasic patients after stroke / Achados audiológicos em pacientes afásicos após acidente vascular encefálico

Objective To outline the audiological findings of aphasic patients after cerebrovascular accidents. Methods This is a cross-sectional study performed between March 2011 and August 2012 in the Speech, Language, and Hearing Pathology Department of the Universidade Federal de São Paulo. A total of 43 aphasic subjects (27 men) were referred for audiological evaluation after stroke, with mean age of 54.48 years. Basic audiological evaluation tests were performed, including pure tone audiometry, speech audiometry (speech recognition threshold and word recognition score), immittance measures (tympanometry and contralateral acoustic reflex), and transient otoacoustic emissions. Results Sensorineural hearing loss was prevalent (78.6%). Speech recognition threshold and word recognition score were not obtained in some patients because they were unable to perform the task. Hearing loss was a common finding in this population. Conclusion Comprehension and/or oral emission disruptions in aphasic patients after stroke compromised conventional speech audiometry, resulting in the need for changes in the evaluation procedures for these patients. .

Objetivo Avaliar os achados audiológicos em pacientes afásicos após acidente vascular encefálico. Métodos Trata-se de um estudo transversal, realizado entre março de 2011 e agosto de 2012 no Departamento de Fonoaudiologia da Universidade Federal de São Paulo. Participaram do estudo 43 pacientes afásicos (27 homens) após acidente vascular encefálico, com média de idade de 54,48 anos. Foram realizados testes que compõem a bateria da avaliação audiológica básica: audiometria tonal liminar, logoaudiometria (limiar de reconhecimento de fala e índice percentual de reconhecimento de fala), medidas de imitância acústica (timpanometria e pesquisa do reflexo acústico contralateral) e emissões otoacústicas transitórias. Resultados A perda auditiva neurossensorial foi prevalente (78,6%). Não foi possível obter o limiar de reconhecimento de fala e o índice percentual de reconhecimento de fala em todos os pacientes, pois alguns eram incapazes de realizar a tarefa. A perda auditiva foi um achado comum nessa população. Conclusão As alterações de compreensão e/ou emissão oral apresentadas por estes pacientes afetaram a logoaudiometria convencional e apontam para a necessidade de uso de outros procedimentos de avaliação nessa população. .

Communication Strategies Of The Nursing Team In The Aphasia After Cerebrovascular Accident / Estrategias De Comunicación Del Equipo De Enfermería En La Afasia Secundaria A Accidente Cerebrovascular / Estratégias De Comunicação Da Equipe De Enfermagem Na Afasia Decorrente De Acidente Vascular Encefálico

This is an exploratory, cross-sectional study of quantitative design that aimed to identify the communication strategies used and reported by the nursing staff in the care of aphasic patients after a stroke. The techniques used were the participant observation and interviews with 27 subjects of the nursing staff of neurological units in a general hospital. The most frequently mentioned strategies were gestures (100%), verbal communication (33.3%), written communication (29.6%) and the touch (18.5 %). Among the observed strategies, the gestures reached 40.7% and the touch was present in all situations, given its instrumental character essential to care. The findings show lack of knowledge of nonverbal, proxemics , kinesics and tacesics communication. No significant differences were observed among the professional categories depending on the length of experience with respect to the strategies reported by members of the nursing staff in the care for aphasic patients.

[Frequency of aphasia resulting from stroke at hospitals affiliated to Tehran university of medical sciences]

Aphasia is common symptom after acute stroke with a prevalence in earlier studies between 21-38%. In Iran; unfortunately no investigation has been reported on the prevalence of aphasia. So the main aim of this study was to investigate the frequency of aphasia after stroke at hospitals affiliated to Tehran University of medical sciences [TUMS]. This study is a cross-sectional design and has been done on 30 patients with brain injury who admitted to TUMS hospitals during three months. The Mississippi Aphasia Screening Test [MAST] was used to screening aphasia patients. The descriptive results indicated, from 22 patients with CVA five cases [22.7%] were aphasic. Mean age of aphasic patients [69.6 years] was more than non-aphasic patients [49.24 years] and of five aphasic patients, three cases [60%] were male and two of them [40%] were female. Also, regarding background diseases, four of five [80%] aphasic patients had history of high blood pressure and diabetes. Results of this study was consistent with prevalence of aphasia in last studies. Also results of this study confirmed other studies based on that etiology of lesion, age, and high blood pressure and diabetes history of the patients plays an important role in prevalence of aphasia
