Awareness and knowledge of dementia and its communication disorders amongst Brazilian speech and language therapists.

BACKGROUND: Speech and language therapists (SLTs) play an important role in assessing and rehabilitating communication disorders in people with dementia, but there is evidence to suggest that they do not receive appropriate training to provide management and support during their training. AIM: To investigate the level of awareness and knowledge that practising SLTs from Brazil have about dementia and their role in the care of dementia through an online survey. METHODS & PROCEDURES: An online survey tool was developed to collect information from practising Brazilian SLTs regarding their knowledge about dementia, awareness about their role in the care of people with dementia, and opinions on how SLTs may be better prepared to work in the dementia field. The survey was disseminated via social media, websites, and e-mail lists of researchers and stakeholders. OUTCOMES & RESULTS: A total of 227 SLTs completed the survey. Participants showed good knowledge of dementia in general, while their answers were less accurate on primary progressive aphasia. Regarding the awareness by SLTs of their role in the care of people with dementia, most agreed or strongly agreed that SLTs could help people in the diagnosis, treatment and prevention of dementia (> 80%). However, fewer participants agreed or strongly agreed that they felt confident in contributing to the treatment and diagnosis process of dementia (about 50%). To improve the training of SLTs in Brazil, most participants believed that it would be necessary to improve the teaching of dementia at the undergraduate speech and language therapy curriculum level and to develop recommendations or guidelines about speech and language therapy practice in dementia. CONCLUSIONS & IMPLICATIONS: The results of this survey point to a need for improvement in the knowledge and confidence of Brazilian SLTs about dementia. To reach this goal, targeted training courses and applied practice opportunities should be embedded within university curricula and training programmes. WHAT THIS PAPER ADDS: What is already known on the subject Many studies confirm the importance of speech and language therapy in the non-pharmacological treatment of people with dementia. However, other evidence suggests to a possible lack of training for Brazilian SLTs, especially in the curriculum of undergraduate courses. What this paper adds to existing knowledge This study reveals that Brazilian SLTs have substantial knowledge of dementia and recognize the significance of their role in treating people with dementia. However, a minority expressed confidence in their ability to assess and treat people with dementia. What are the potential or actual clinical implications of this work? The findings of this research demonstrate that Brazilian SLTs have good knowledge of dementia and endorse their professional role in dementia care; however, they lack confidence in their own skills and expertise in diagnostic assessment and treatment of dementia. Interventions aimed at boosting the SLT's confidence level could lead to improved patients outcomes and overall quality of care within clinical settings.

The Discourse Profile in Corticobasal Syndrome: A Comprehensive Clinical and Biomarker Approach.

The aim of this study was to characterize the oral discourse of CBS patients and to verify whether measures obtained during a semi-spontaneous speech production could differentiate CBS patients from controls. A second goal was to compare the performance of patients with CBS probably due to Alzheimer's disease (CBS-AD) pathology and CBS not related to AD (CBS-non-AD) in the same measures, based on the brain metabolic status (FDG-PET) and in the presence of amyloid deposition (amyloid-PET). Results showed that CBS patients were significantly different from controls in speech rate, lexical level, informativeness, and syntactic complexity. Discursive measures did not differentiate CBS-AD from CBS-non-AD. However, CBS-AD displayed more lexical-semantic impairments than controls, a profile that is frequently reported in patients with clinical AD and the logopenic variant of primary progressive aphasia (lvPPA). CBS-non-AD presented mainly with impairments related to motor speech disorders and syntactic complexity, as seen in the non-fluent variant of PPA.

Diagnosis of Alzheimer's disease: recommendations of the Scientific Department of Cognitive Neurology and Aging of the Brazilian Academy of Neurology.

This paper presents the consensus of the Scientific Department of Cognitive Neurology and Aging from the Brazilian Academy of Neurology on the diagnostic criteria for Alzheimer's disease (AD) in Brazil. The authors conducted a literature review regarding clinical and research criteria for AD diagnosis and proposed protocols for use at primary, secondary, and tertiary care levels. Within this clinical scenario, the diagnostic criteria for typical and atypical AD are presented as well as clinical, cognitive, and functional assessment tools and complementary propaedeutics with laboratory and neuroimaging tests. The use of biomarkers is also discussed for both clinical diagnosis (in specific conditions) and research.

Language in corticobasal syndrome: a systematic review.

Language is commonly impacted in corticobasal syndrome (CBS). However, the profile and type of language assessment in CBS are poorly studied. OBJECTIVE: To identify language impairments in CBS. METHODS: A search was performed in the Medline/PubMed database, according to the PRISMA criteria, using the keywords "corticobasal syndrome" OR "corticobasal degeneration" AND "language". Articles on CBS covering language assessment that were written in English were included, with no constraints on the publication date. RESULTS: A total of 259 articles were found and 35 were analyzed, consisting of 531 participants. Twenty-eight studies showed heterogeneous language deficits and seven mentioned nonfluent primary progressive aphasia. The most used tests were the Western Aphasia Battery (8 studies) and the Boston Naming Test (8 studies). CONCLUSION: It was not possible to identify a unique linguistic profile in CBS.

A linguagem encontra-se comumente alterada na síndrome corticobasal (SCB). No entanto, o perfil e a forma de avaliação da linguagem na SCB são pouco estudados. OBJETIVO: identificar as alterações de linguagem na SCB. MÉTODO: Realizou-se uma busca na base de dados Medline/PubMed, com as palavras-chave "síndrome corticobasal" OU "degeneração corticobasal" E "linguagem". Artigos sobre SCB envolvendo avaliação de linguagem, escritos em inglês, foram incluídos, sem restrição de data de publicação. RESULTADOS: Foram encontrados 259 artigos, e 35 estudos foram analisados, abrangendo 531 sujeitos. Um total de 28 estudos mostraram déficits heterogêneos de linguagem, e sete mencionaram afasia progressiva primária não-fluente. Os testes mais utilizados foram Western Aphasia Battery (8 estudos) e o Teste de Nomeação de Boston (8 estudos). CONCLUSÃO: Não foi possível identificar um perfil linguístico único em pacientes com SCB.

Textual Inference Comprehension in Mild Cognitive Impairment: The Influence of Semantic Processing and Verbal Episodic Memory.

Language complaints, especially in complex tasks, may occur in mild cognitive impairment (MCI). Various language measures have been studied as cognitive predictors of MCI conversion to Alzheimer's type dementia. Understanding textual inferences is considered a high-demanding task that recruits multiple cognitive functions and, therefore, could be sensitive to detect decline in the early stages of MCI. Thus, we aimed to compare the performance of subjects with MCI to healthy elderly in a textual inference comprehension task and to determine the best predictors of performance in this ability considering one verbal episodic memory and two semantic tasks. We studied 99 individuals divided into three groups: (1) 23 individuals with amnestic mild cognitive impairment (aMCI), (2) 42 individuals with non-amnestic mild cognitive impairment (naMCI), (3), and (4) 34 cognitively healthy individuals for the control group (CG). A reduced version of The Implicit Management Test was used to assess different types of inferential reasoning in text reading. MCI patients performed poorer than healthy elderly, and there were no differences between MCI subgroups (amnestic and non-amnestic). The best predictors for inference-making were verbal memory in the aMCI and semantic tasks in the naMCI group. The results confirmed that the failure to understand textual inferences can be present in MCI and showed that different cognitive skills like semantic knowledge and verbal episodic memory are necessary for inference-making.

Inference comprehension from reading in individuals with mild cognitive impairment.

Inference comprehension is a complex ability that recruits distinct cognitive domains, such as language, memory, attention, and executive functions. Therefore, it might be sensitive to identify early deficits in subjects with MCI. To compare the performance of subjects with mild cognitive impairment (MCI) in an inference reading comprehension task, and to analyze the correlations between inferential comprehension and other cognitive functions. We studied 100 individuals aged 60 and over, divided into MCI (50) [aMCI (35), naMCI (15)], and cognitively healthy individuals [controls (50)]. The Implicit Management Test (IMT) was used to assess inference in reading comprehension in five categories: explicit, logical, distractor, pragmatic, and "others". MCI group performed worse than controls in logical, pragmatic, distractor, and "others" questions (p < 0.01). The aMCI and naMCI subgroups presented a similar performance in all types of questions (p > 0.05). We observed significant correlations between the total IMT score and the TMT-A in the naMCI group (r = - 0.562, p = 0.036), and the Rey-Osterrieth Complex Figure and RAVLT tasks in the aMCI group (r = 0.474, p = 0.010 and r = 0.593, p = 0.0001, respectively). The MCI group as a whole performed worse than controls on the logical, pragmatic, other and distractor questions, and consequently on the total score. There were no differences in explicit questions, which impose lower inferential demands. The aMCI group suffered a significant impact from memory on inference comprehension, and difficulties in executive functions impacted naMCI performance. The IMT was useful to differentiate MCI patients from cognitively healthy individuals, but not MCI subgroups among themselves.

Metabolic and Structural Signatures of Speech and Language Impairment in Corticobasal Syndrome: A Multimodal PET/MRI Study.

Introduction: Corticobasal syndrome (CBS) is a progressive neurological disorder related to multiple underlying pathologies, including four-repeat tauopathies, such as corticobasal degeneration and progressive supranuclear palsy, and Alzheimer's disease (AD). Speech and language are commonly impaired, encompassing a broad spectrum of deficits. We aimed to investigate CBS speech and language impairment patterns in light of a multimodal imaging approach. Materials and Methods: Thirty-one patients with probable CBS were prospectively evaluated concerning their speech-language, cognitive, and motor profiles. They underwent positron emission tomography with [18F]fluorodeoxyglucose (FDG-PET) and [11C]Pittsburgh Compound-B (PIB-PET) on a hybrid PET-MRI machine to assess their amyloid status. PIB-PET images were classified based on visual and semi-quantitative analyses. Quantitative group analyses were performed on FDG-PET data, and atrophy patterns on MRI were investigated using voxel-based morphometry (VBM). Thirty healthy participants were recruited as imaging controls. Results: Aphasia was the second most prominent cognitive impairment, presented in 67.7% of the cases, following apraxia (96.8%). We identified a wide linguistic profile, ranging from nonfluent variant-primary progressive aphasia to lexical-semantic deficits, mostly with impaired verbal fluency. PIB-PET was classified as negative (CBS-A- group) in 18/31 (58%) and positive (CBS-A+ group) in 13/31 (42%) patients. The frequency of dysarthria was significantly higher in the CBS-A- group than in the CBS-A+ group (55.6 vs. 7.7%, p = 0.008). CBS patients with dysarthria had a left-sided hypometabolism at frontal regions, with a major cluster at the left inferior frontal gyrus and premotor cortex. They showed brain atrophy mainly at the opercular frontal gyrus and putamen. There was a positive correlation between [18F]FDG uptake and semantic verbal fluency at the left inferior (p = 0.006, R 2 = 0.2326), middle (0.0054, R 2 = 0.2376), and superior temporal gyri (p = 0.0066, R 2 = 0.2276). Relative to the phonemic verbal fluency, we found a positive correlation at the left frontal opercular gyrus (p = 0.0003, R 2 = 0.3685), the inferior (p = 0.0004, R 2 = 0.3537), and the middle temporal gyri (p = 0.0001, R 2 = 0.3993). Discussion: In the spectrum of language impairment profile, dysarthria might be helpful to distinguish CBS patients not related to AD. Metabolic and structural signatures depicted from this feature provide further insights into the motor speech production network and are also helpful to differentiate CBS variants.

Treatment of agrammatism in oral and written production in patients with Broca's aphasia The use of implicit and explicit learning.

Several approaches to the rehabilitation of agrammatism use implicit and explicit learning methods. OBJECTIVE: To verify the effect of adapted Mapping Therapy and ORLA methods (explicit versus implicit learning) on the oral and written production in spontaneous language among agrammatic patients with Broca's aphasia. METHODS: Six individuals were submitted to Mapping Therapy and ORLA (Oral Reading for Language in Aphasia) treatments. Samples of oral and written production from a picture description task were compared pre and post-treatment. RESULTS: In Mapping Therapy, the patients presented better performance after the training for the variables related to written production: number of words, nouns, verbs, closed-class words, and number of complete sentences. Regarding oral output, the patients had similar performance before and after the therapeutic process. In ORLA, the patients presented a significant difference before and after the therapeutic process in the variables related to oral production, increasing the number of words, number of verbs, and speech rate. There was no difference in pre and post-treatment performance in written production. CONCLUSION: Both implicit and explicit learning can be used in the treatment of agrammatism. Mapping Therapy was more effective for the treatment of agrammatism in written production, while ORLA was more effective for the agrammatism in oral production.

Várias abordagens terapêuticas para a reabilitação do agramatismo utilizam métodos implícitos e explícitos de aprendizado. OBJETIVO: Verificar o efeito dos métodos adaptados Mapping Therapy e ORLA (aprendizagem explícita versus implícita) na produção oral e escrita de discurso em pacientes agramáticos com afasia de Broca. MÉTODOS: Seis indivíduos foram submetidos aos tratamentos Mapping Therapy e ORLA. Amostras das produções oral e escrita na tarefa de descrição da prancha foram comparadas antes e após o tratamento. RESULTADOS: No método Mapping Therapy, os pacientes apresentaram melhor desempenho após o tratamento nas seguintes variáveis ​​relacionadas à produção escrita: número de palavras, substantivos, verbos, palavras de classe fechada e número de frases completas. Em relação à emissão oral, os pacientes mantiveram desempenho semelhante pré e pós processo terapêutico. No método ORLA, os pacientes apresentaram diferença significativa antes e após o processo terapêutico nas variáveis ​​relacionadas à produção oral, com aumento no número de palavras, número de verbos e velocidade de fala. Não houve diferença no desempenho pré e pós tratamento na produção escrita. CONCLUSÃO: Tanto a aprendizagem implícita como a explícita têm o potencial de serem usadas no tratamento do agramatismo. A Mapping Therapy foi mais eficaz no tratamento do agramatismo na produção escrita, enquanto o ORLA foi mais eficaz para o agramatismo na produção oral.

Inference comprehension in text reading: Performance of individuals with right- versus left-hemisphere lesions and the influence of cognitive functions.

BACKGROUND: Right-hemisphere lesions (RHL) may impair inference comprehension. However, comparative studies between left-hemisphere lesions (LHL) and RHL are rare, especially regarding reading comprehension. Moreover, further knowledge of the influence of cognition on inferential processing in this task is needed. OBJECTIVES: To compare the performance of patients with RHL and LHL on an inference reading comprehension task. We also aimed to analyze the effects of lesion site and to verify correlations between cognitive functions and performance on the task. METHODS: Seventy-five subjects were equally divided into the groups RHL, LHL, and control group (CG). The Implicit Management Test was used to evaluate inference comprehension. In this test, subjects read short written passages and subsequently answer five types of questions (explicit, logical, distractor, pragmatic, and other), which require different types of inferential reasoning. The cognitive functional domains of attention, memory, executive functions, language, and visuospatial abilities were assessed using the Cognitive Linguistic Quick Test (CLQT). RESULTS: The LHL and RHL groups presented difficulties in inferential comprehension in comparison with the CG. However, the RHL group presented lower scores than the LHL group on logical, pragmatic and other questions. A covariance analysis did not show any effect of lesion site within the hemispheres. Overall, all cognitive domains were correlated with all the types of questions from the inference test (especially logical, pragmatic, and other). Attention and visuospatial abilities affected the scores of both the RHL and LHL groups, and only memory influenced the performance of the RHL group. CONCLUSIONS: Lesions in either hemisphere may cause difficulties in making inferences during reading. However, processing more complex inferences was more difficult for patients with RHL than for those with LHL, which suggests that the right hemisphere plays an important role in tasks with higher comprehension demands. Cognition influences inferential processing during reading in brain-injured subjects.

Effect of education on listening comprehension of sentences on healthy elderly: analysis of number of correct responses and task execution time.

PURPOSE: To analyze the effect of education on sentence listening comprehension on cognitively healthy elderly. METHODS: A total of 111 healthy elderly, aged 60-80 years of both genders were divided into two groups according to educational level: low education (0-8 years of formal education) and high education (≥9 years of formal education). The participants were assessed using the Revised Token Test, an instrument that supports the evaluation of auditory comprehension of orders with different working memory and syntactic complexity demands. The indicators used for performance analysis were the number of correct responses (accuracy analysis) and task execution time (temporal analysis) in the different blocks. RESULTS: The low educated group had a lower number of correct responses than the high educated group on all blocks of the test. In the temporal analysis, participants with low education had longer execution time for commands on the first four blocks related to working memory. However, the two groups had similar execution time for blocks more related to syntactic comprehension. CONCLUSION: Education influenced sentence listening comprehension on elderly. Temporal analysis allowed to infer over the relationship between comprehension and other cognitive abilities, and to observe that the low educated elderly did not use effective compensation strategies to improve their performances on the task. Therefore, low educational level, associated with aging, may potentialize the risks for language decline.

Healthy Aging and Compensation of Sentence Comprehension Auditory Deficits.

OBJECTIVES: To analyze the effect of aging on sentence auditory comprehension and to study the relationship between this language skill and cognitive functions (attention, working memory, and executive functions). METHODS: A total of 90 healthy subjects were divided into three groups: adults (50-59 years), young-old (60-69 years), and old-old (70-80 years). Subjects were assessed using the Revised Token Test. The measures used for performance analysis were number of correct answers (accuracy) and execution time of commands on the different subtests. RESULTS: Regarding accuracy, groups showed similar performance on the first blocks, but the young-old and old-old performed worse than adults on blocks 9 and 10. With respect to execution time, groups differed from block 2 (i.e., the groups differed for all blocks, except for block 1), with the worst performance observed in the old-old group, followed by that of the young-old group. Therefore, the elderly required more time to attain performance similar to that of adults, showing that time measurements are more sensitive for detecting the effects of age. Sentence comprehension ability is correlated with cognitive test performance, especially for global cognition and working memory tests. CONCLUSIONS: Healthy aging is characterized by the ability to compensate for difficulties in linguistic processing, which allows the elderly to maintain functional communication.

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.

Inference comprehension during reading: influence of age and education in normal adults.

PURPOSE: To determine the effect of age and education on inferential comprehension from written texts in normal individuals. METHODS: A total of 224 normal adults were stratified into nine groups according to age (young: 18-39 years, adults: 40-59 years, and elderly: 60-79 years) and educational level (low ≤4 years, medium: 5-8 years and high >8 years) and were evaluated through the battery La gestion de l'implicite (Implicit Information Management Test) to determine the ability to make inferences through different types of questions: explicit, logical, distractor, pragmatic and others. RESULTS: The elderly showed worse performance for total score and distractor questions. Regarding educational level, all groups differed on explicit, logical, distractor questions, and on total test score. Subjects with high schooling performed better on pragmatic inferences and others. CONCLUSION: Age influence on the comprehension of inferences may be due to difficulties in attention and executive functions. The strong effect of education can be explained by the interaction of inferential abilities with other cognitive functions such as working memory, vocabulary span, as well as world knowledge.

Sentence production in rehabilitation of agrammatism: A case study.

Agrammatism is characterized by morphosyntactic deficits in production of sentences. Studies dealing with the treatment of these deficits are scarce and their results controversial. The present study describes the rehabilitation of a case diagnosed as chronic Broca's aphasia, with agrammatism, using a method directed to sentence structural deficits. The method aims to expand the grammatical repertoire by training production of sentences with support from contexts that stimulate actions and dialogues. The patient showed positive results on all types of sentences trained and generalized the gains to spontaneous speech. However, these benefits were not sustained in the long term.

O agramatismo é marcado por déficits morfossintáticos na produção das sentenças. Estudos que abordam o tratamento destas dificuldades são escassos e controversos. O presente estudo descreveu a reabilitação de uma paciente com agramatismo associado à afasia de Broca em fase crônica, por meio de programa de estruturação de sentenças. Trata-se de método que visa à expansão do repertório gramatical através do treino com apoio de contextos que estimulam ações e diálogos. A paciente obteve resultados positivos em todos os tipos de frases treinadas, com ganhos generalizados para contextos de fala espontânea. No entanto, os benefícios não se mantiveram em longo termo.

Communication map of elderly people Sociodemographic and cognitive-linguistic aspects.

Language and communication difficulties may occur in the elderly population. This is the case of the tip-of-the-tongue phenomenon and receptive and auditory comprehension difficulties. Few studies have focused on examining the effects of social exposure on maintaining communication in the aging process. OBJECTIVES: [1] To describe the communication map of healthy elderly subjects; [2] To search for associations between frequency and time dedicated to communication and cognitive and sociodemographic factors. METHODS: Healthy elderly subjects were submitted to cognitive screening, the Token Test - Revised, and the Verbal Fluency test, and answered the ASHA-FACS and the Circles of Communication Partners questionnaires. RESULTS: 55 subjects, 67% female, with ages over 60 years and varied schooling were included in the sample. Interlocutors in the circle of close friends and acquaintances predominated in the communication map, although the time devoted to communication with these partners was lower than in other circles. Overall, the elderly reported no deficits in language comprehension, with some reports of the tip-of-the-tongue phenomenon. Poor performances on the Token Test - Revised and in phonemic verbal fluency along with reports of communication functionality indicated that these subjects compensate for their problems. CONCLUSION: Older subjects with lower schooling tended to predominantly communicate within the family circle. Within other circles, the number of hours devoted to communication and dialogue partners was not associated with age or schooling. The time devoted to the circle of communication with friends may indicate cognitive difficulties.

Dificuldades de linguagem e comunicação podem ocorrer na população idosa. Esse é o caso do fenômeno da ponta da língua e também dificuldades de recepção e compreensão auditiva. Poucos estudos se dedicam a examinar efeitos da exposição social na manutenção da comunicação, no processo do envelhecimento. OBJETIVOS: [1] Descrever o mapa de comunicação de idosos saudáveis; [2] Buscar associações entre frequência e tempo destinados à comunicação e fatores cognitivos e sociodemográficos. MÉTODOS: Foram examinados idosos saudáveis que realizaram rastreio cognitivo, Token Test-Revisado, Fluência verbal e responderam aos questionários ASHA-FAcs e Círculos de Interlocutores de Comunicação. RESULTADOS: 55 sujeitos, 67% do gênero feminino, idade acima de 60 anos e escolaridades variadas compuseram a amostra. No mapa de comunicação predominaram interlocutores no círculo de amigos próximos e conhecidos embora o tempo dedicado à comunicação com esses interlocutores seja menor do que nos outros círculos. Na média geral os idosos não relataram déficits de compreensão de linguagem e houve relatos de dificuldades do tipo fenômeno de ponta de língua. Baixos desempenhos no TT-R e na fluência verbal fonêmica ao lado do relato de funcionalidade na comunicação indica que esses sujeitos compensam seus problemas. CONCLUSÃO: O número de horas de interlocução e de interlocutores não está associado à idade e escolaridade, exceto para indivíduos com maior idade e menor escolaridade os quais tendem a privilegiar a interlocução em seu círculo familiar. O tempo dedicado ao círculo de comunicação com amigos pode sinalizar dificuldades de natureza cognitiva.

Effect of education on listening comprehension of sentences on healthy elderly: analysis of number of correct responses and task execution time / Efeito da escolaridade na compreensão auditiva de sentenças em idosos saudáveis: análise do número de acertos e tempo de execução da tarefa

ABSTRACT Purpose To analyze the effect of education on sentence listening comprehension on cognitively healthy elderly. Methods A total of 111 healthy elderly, aged 60-80 years of both genders were divided into two groups according to educational level: low education (0-8 years of formal education) and high education (≥9 years of formal education). The participants were assessed using the Revised Token Test, an instrument that supports the evaluation of auditory comprehension of orders with different working memory and syntactic complexity demands. The indicators used for performance analysis were the number of correct responses (accuracy analysis) and task execution time (temporal analysis) in the different blocks. Results The low educated group had a lower number of correct responses than the high educated group on all blocks of the test. In the temporal analysis, participants with low education had longer execution time for commands on the first four blocks related to working memory. However, the two groups had similar execution time for blocks more related to syntactic comprehension. Conclusion Education influenced sentence listening comprehension on elderly. Temporal analysis allowed to infer over the relationship between comprehension and other cognitive abilities, and to observe that the low educated elderly did not use effective compensation strategies to improve their performances on the task. Therefore, low educational level, associated with aging, may potentialize the risks for language decline.

RESUMO Objetivo Analisar o efeito da escolaridade na compreensão auditiva de sentenças em idosos cognitivamente saudáveis. Método Foram avaliados 111 idosos normais, com idades entre 60 e 80 anos, de ambos os gêneros, divididos em dois grupos, de acordo com a escolaridade: baixa escolaridade (0 a 8 anos de ensino formal) e alta escolaridade (9 ou mais anos de ensino formal). Os indivíduos foram examinados por meio do Token Test Revisado, que dá suporte para a avaliação da compreensão auditiva de ordens com diferentes demandas de memória operacional e complexidade sintática. Os indicadores utilizados para análise do desempenho foram números de acertos (análise de acurácia) e tempo de execução da tarefa (análise temporal) nos diferentes blocos. Resultados O grupo de baixa escolaridade apresentou menor número de acertos que o grupo de alta escolaridade em todos os blocos do teste. Na análise temporal, os idosos de baixa escolaridade apresentaram maior tempo para execução das ordens nos primeiros quatro blocos, mais relacionados à memória operacional. Porém, os grupos apresentaram tempo de execução semelhante quanto aos blocos mais relacionados à compreensão sintática. Conclusão A escolaridade influenciou a habilidade de compreensão auditiva de sentenças em indivíduos idosos. A análise temporal permitiu inferir sobre a relação da compreensão com outras habilidades cognitivas e observar que os idosos de baixa escolaridade não utilizam estratégias eficazes de compensação para melhorar o desempenho na tarefa. Portanto, o baixo nível educacional, associado ao envelhecimento, pode potencializar os riscos para o declínio da linguagem.

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. .
