Oral dyspraxia in self-limited epilepsy with centrotemporal spikes: a comparative study with a control group / Dispraxia oral em epilepsia autolimitada com espículas centrotemporais: um estudo comparativo com grupo controle

ABSTRACT Background: self-limited epilepsy with centrotemporal spikes, previously considered benign focal childhood epilepsy with centrotemporal spikes show clinical signs of involvement of Rolandic areas, mainly lower area, which may affect the planning and execution of motor sequences. Objective: This study aimed to evaluated oral praxis in children with self-limited epilepsy with centrotemporal spikes and compare to the age-matched control group. Methods: This was a descriptive study with 74 children with self-limited epilepsy with centrotemporal spikes, with the classical forms according to International League Against Epilepsy, and between 4 and 15 years of age, selected from the child neurology outpatient clinic of the Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo, São Paulo, Brazil, and 239 age-matched and educational level-matched (convenience sampling) control children. All children were submitted to the battery of oral volitional movements, which consisted of 44 tests for oral movement (tongue, lip, cheek, jaw, and palate) and 34 phonemes and consonant cluster tasks, with simple and sequenced oral movements. Results: The mean age and standard deviation (SD) of children with epilepsy was 9.08 years (SD 2.55) and of controls 9.61 years (SD 3.12). The results showed significant differences between the groups with a poorer performance of children with epilepsy compared to children without epilepsy in simple and particularly in sequenced movements. Conclusion: These findings can be attributed to the genetically determined immaturity of cortical structures related to motor planning in children with self-limited epilepsy with centrotemporal spikes.

RESUMO Antecedentes: Epilepsia autolimitada com descarga centrotemporal, previamente designada por epilepsia benigna focal infantil com espículas centrotemporais, mostra sinais clínicos de envolvimento de áreas rolândicas, principalmente área inferior, que podem afetar o planejamento e a execução de sequências motoras. Objetivo: Este estudo visou avaliar a práxis oral em crianças com epilepsia autolimitada com espículas centrotemporais e comparar com o grupo de controle de mesma idade e grau de escolaridade. Métodos: Tratou-se de um estudo descritivo, com 74 crianças com epilepsia autolimitada com espículas centrotemporais selecionadas no ambulatório de neurologia infantil do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, São Paulo, Brasil, e 239 crianças do grupo controle da mesma faixa etária e grau de escolaridade. Todas as crianças foram submetidas à bateria de tarefas de movimento oral volitivo, que inclui movimentos orais simples e sequenciados. Resultados: A idade média das crianças com epilepsia era de 9,08 anos (desvio padrão - DP 2,55) e dos controles 9,61 anos (DP 3,12). Os resultados mostraram diferenças significativas entre os grupos, com desempenho mais fraco das crianças com epilepsia em comparação ao das crianças saudáveis, em movimentos simples e particularmente em movimentos sequenciados. Conclusão: Esses resultados podem ser atribuídos à imaturidade geneticamente determinada das estruturas corticais relacionadas com o planejamento motor em crianças com epilepsia autolimitada com espículas centrotemporais.

Swallowing in behavioral variant frontotemporal dementia.

BACKGROUND: Swallowing and feeding problems may occur with the progression of behavioral variant frontotemporal dementia (bvFTD) and can impair the anticipatory and oral preparatory phases of swallowing. OBJECTIVE: To characterize swallowing problems and the feeding situation of patients with bvFTD and to correlate the swallowing problems with functionality, executive functions, cognitive and behavioral features. METHODS: Consecutive outpatients with bvFTD in mild, moderate and severe dementia stages were recruited along with their caregivers. Patients and caregivers were screened with the following scales: "Mini-Mental State Examination", "Severe Mini-Mental State Examination", "FTLD-modified Clinical Dementia Rating", "Neuropsychiatric Inventory", "Frontal Assessment Battery", "Index of Independence in Activities of Daily Living", "Swallowing Rating Scale" and "Assessment of Feeding and Swallowing Difficulties in Dementia". RESULTS: Overall, thirty patients with bvFTD were included along with their caregivers. Patients with bvFTD showed feeding and swallowing difficulties such as: messy to eat, passivity, coughing and choking, difficulty with some food consistencies and with specific food. Swallowing problems in bvFTD correlated with impaired functionality (p<0.05) and cognition (p<0.05), executive dysfunction (p<0.01) and behavioral features (p<0.01). Caregivers had great difficulty in managing the feeding situation during mealtime, with different characteristics in each dementia stage. CONCLUSION: Patients with bvFTD had inappropriate speed eating, passivity, coughing and choking starting in the mild dementia stage, and these problems worsen in the severe stage. Such difficulties affected caregiver performance during mealtime. The correlations indicated that swallowing difficulties tend to follow cognitive and behavioral decline in patients with bvFTD.

RESUMO Introdução: Os problemas na situação de alimentação e deglutição podem ocorrer com a progressão da variante comportamental da demência frontotemporal (DFT-vc) e alterar as fases antecipatória e preparatória oral da deglutição. Objetivo: Caracterizar os problemas de deglutição e a situação de alimentação de pacientes com DFT-vc e correlacionar os problemas de deglutição com a funcionalidade, funções executivas, aspectos cognitivos e comportamentais. Métodos: Foram recrutados pacientes ambulatoriais com DFT-vc nas fases leve, moderada e grave da demência, e seus respectivos cuidadores. Os pacientes e cuidadores foram avaliados com as escalas: "Mini-Exame do Estado Mental", "Mini-Exame do Estado Mental Grave", "Escala de Avaliação Clínica da Demência Modificada - DFT", "Inventário Neuropsiquiátrico", "Bateria de Avaliação Frontal", "Índice de Independência nas Atividades da Vida Diária", "Escala Funcional de Avaliação da Deglutição" e "Avaliação das Dificuldades de Alimentação e Deglutição na Demência". Resultados: Foram incluídos 30 pacientes com DFT-vc, e seus cuidadores. Pacientes com DFT-vc apresentaram dificuldades de alimentação e deglutição como: confusão na alimentação, passividade, tosse e asfixia, dificuldades com algumas consistências alimentares e alimentos específicos. Problemas de deglutição na DFT-vc correlacionaram-se com funcionalidade prejudicada (p<0,05) e cognição (p<0,05), disfunção executiva (p<0,01) e características comportamentais (p<0,01). Os cuidadores tiveram grande dificuldade em gerenciar a situação de alimentação diante de diferentes problemas em cada fase da demência. Conclusão: Pacientes com DFT-vc apresentaram velocidade de alimentação inapropriada, passividade, tosse e engasgos já na fase leve da doença, com piora na fase grave. As correlações indicaram que as alterações de deglutição tendem a seguir o declínio cognitivo e comportamental na DFT-vc.

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.

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.

Quanti-qualitative components of the semantic verbal fluency test in cognitively healthy controls, mild cognitive impairment, and dementia subtypes.

This study is aimed to evaluating the underlying cognitive strategies used during Semantic Verbal Fluency (SVF) performance and comparing the differences between cognitively healthy controls (CHC), amnestic and amnestic-multiple domain mild cognitive impairment (a-MCI and a-md-MCI), Alzheimer's disease (AD), Lewy body dementia (LBD), and behavioral variant frontotemporal dementia (bvFTD). The cross-sectional study comprised 236 participants involving 78 CHC individuals, 33 a-MCI and 48 a-md-MCI, 39 AD, 22 LBD, and 16 bvFTD patients. Scores differed significantly when comparing CHC with dementia groups, showing medium to large variances. The best components in distinguishing between CHC and the dementia groups were the SVF-Total score and SVF-Cluster Size variables. CHC showed different performance in the SVF-Cluster Size variable compared with a-md-MCI, AD, and bvFTD; whereas, in the SVF-Mean Cluster Size, CHC differed from MCI's, AD, and LBD. The switching component displayed smaller capacity to differentiate between the clinical groups. The effect size was large comparing AD with bvFTD (1.267) and medium comparing AD with LBD (0.689) using the SVF-Cluster Size variable, but small using the other variables for the comparisons between dementia groups. Quanti-qualitative examination of the SVF may provide a valuable clue in distinguishing CHC from MCI and different dementia subtypes.

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.

Analysis of macrolinguistic aspects of narratives from individuals with Alzheimer's disease, mild cognitive impairment, and no cognitive impairment.

INTRODUCTION: The depiction of features in discourse production promotes accurate diagnosis and helps to establish the therapeutic intervention in cognitive impairment and dementia. We aimed to identify alterations in the macrolinguistic aspects of discourse using a new computational tool. METHODS: Sixty individuals, aged 60 years and older, were distributed in three different groups: mild Alzheimer's disease (mAD), amnestic mild cognitive impairment, and healthy controls. A narrative created by individuals was analyzed through the Coh-Metrix-Dementia program, extracting the features of interest automatically. RESULTS: mAD showed worse overall performance compared to the other groups: less informative discourse, greater impairment in global coherence, greater modalization, and inferior narrative structure. It was not possible to discriminate between amnestic mild cognitive impairment and healthy controls. DISCUSSION: Our results are in line with the literature, verifying a pathological change in the macrostructure of discourse in mAD.

Educational status influences cognitive-motor learning in older adults: going to university provides greater protection against aging than going to high school.

OBJECTIVE: To investigate if middle-aged and older adults with a higher education would differ from those with an average education in cognitive-motor tasks involving lower limb function. METHODS: A walking version of the Trail Making Test (Walking Executive Function Task, [WEFT]) was used. Eighty volunteers (40: 50-65 years; 40: 66-80 years) were subdivided into average (6-11years of education) and higher education (12-17 years). They received two training sessions (session 1: eight repetitions, session 2: four repetitions), with a one week-interval between them. The Timed Up and Go (TUG) test was performed before and after the training. RESULTS: Volunteers with an average education showed longer times on the WEFT than those with a higher education. Older adults showed lower retention than middle-aged adults (p < 0.001). The TUG was faster after the WEFT training (p < 0.001). CONCLUSION: The impact of education was observed when locomotion was associated with cognitive tasks. Average education resulted in poorer performance and learning than higher education, mainly in older adults. Gait speed increased after training.

RESUMO Objetivo: Investigar se adultos e idosos com escolaridade alta teriam aprendizagem diferente de adultos e idosos com escolaridade média em uma tarefa cognitivo-motora envolvendo função de membros inferiores. Método: A tarefa foi baseada no Trail Making Test (Tarefa de Deambulação Funcional, TDF). Oitenta voluntários (40:50-65 anos; 40:66-80 anos) foram subdivididos em escolaridade média (6-11 anos) e alta (12-17 anos) e realizaram duas sessões de treinamento (1: oito repetições, 2: quatro repetições), com intervalo de uma semana. O Timed Up and Go (TUG) foi realizado antes e após o treinamento. Resultados: Voluntários com escolaridade média levaram mais tempo para concluir a TDF do que voluntários com escolaridade alta (p < 0.001). Idosos apresentaram menor retenção do que adultos (p < 0.001). TUG foi mais rápido após o treinamento. Conclusão: O impacto da escolaridade foi observado quando a locomoção foi associada com tarefas cognitivas. Voluntários com escolaridade média apresentaram menor aprendizagem do que com escolaridade alta, principalmente idosos. A velocidade da marcha aumentou com o treinamento.

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.

Cognitive or Cognitive-Motor Executive Function Tasks? Evaluating Verbal Fluency Measures in People with Parkinson's Disease.

INTRODUCTION: Executive function deficits are observed in people with Parkinson's disease (PD) from early stages and have great impact on daily living activities. Verbal fluency and oral diadochokinesia involve phonarticulatory coordination, response inhibition, and phonological processing and may also be affected in people with PD. This study aimed to describe the performance of PD patients and an age- and education-matched control group on executive function, verbal fluency, and oral diadochokinesia tests and to investigate possible relationships between them. METHODS: Forty people with PD and forty controls were evaluated with Trail Making Test (TMT, executive function) and phonemic/semantic verbal fluency and oral diadochokinesia (/pataka/) tests. Groups were compared by ANOVA and relationships were investigated by Pearson tests. RESULTS: People with PD showed longer times in parts A and B of TMT. They also said fewer words in phonemic/semantic verbal fluency tests and less syllables in the diadochokinesia test. Oral diadochokinesia strongly correlated to parts A and B of TMT and to phonemic verbal fluency. CONCLUSION: Oral diadochokinesia was correlated to executive function and verbal fluency. The cognitive-motor interaction in verbal fluency and oral diadochokinesia must be considered not to overestimate the cognitive or motor impairments in people with PD.

Aphasia in vascular lesions of the basal ganglia: A comprehensive review.

Between 1970 and 1990, the study of aphasia secondary to subcortical lesions (including the basal ganglia - BG) was largely driven by the advent of modern neuroimaging techniques such as MRI and PET. However, attempts to characterize a pattern of language abnormalities in patients with basal ganglia lesions proved unfruitful. We conducted a comprehensive review of language disturbances after vascular lesions in the BG. Literature search in Medline and LILACS (1966-2016) and PsychINFO (last 25years) was conducted, and returned 145 articles, with 57 eligible for the review yielding data on 303 patients. We report the clinical and neuroimaging features of these cases. Results showed that aphasias caused by BG lesions are heterogeneous with weak clinicoanatomical correlations. Data derived from follow-up and flow/metabolism studies suggest that subcortical aphasia caused by BG lesions involves hypoperfusion in the cortical territories of the middle cerebral/internal carotid arteries (MCA/ICA) and their branches.

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.

Heterogeneity in semantic priming effect with a lexical decision task in patients after left hemisphere stroke / Heterogeneidade no efeito de priming semântico em pacientes após lesão cerebral do hemisfério esquerdo

ABSTRACT Investigations on the semantic priming effect (SPE) in patients after left hemisphere (LH) lesions have shown disparities that may be explained by the variability in performance found among patients. The aim of the present study was to verify the existence of subgroups of patients after LH stroke by searching for dissociations between performance on the lexical decision task based on the semantic priming paradigm and performance on direct memory, semantic association and language tasks. All 17 patients with LH lesions after stroke (ten non-fluent aphasics and seven non aphasics) were analyzed individually. Results indicated the presence of three groups of patients according to SPE: one exhibiting SPE at both stimulus onset asynchronies (SOAs), one with SPE only at long SOA, and another, larger group with no SPE.

RESUMO As investigações sobre o efeito de priming semântico (SPE) em pacientes após lesões cerebrais no hemisfério esquerdo (LH) têm mostrado divergências que podem ser explicadas pela variabilidade no desempenho encontrado entre os pacientes. O objetivo do presente estudo foi verificar a existência de subgrupos de pacientes pós-AVC no hemisfério esquerdo do cérebro, buscando associações e dissociações entre o desempenho na tarefa de decisão lexical no paradigma de priming semântico e o desempenho em tarefas diretas de memória, tarefas de associação semântica e de linguagem. Todos os 17 pacientes com lesão no LH após acidente vascular cerebral (dez afásicos não-fluentes e sete não afásicos) foram analisados individualmente. Os resultados indicaram a presença de três grupos de pacientes de acordo com o efeito de priming semântico. Um grupo de participantes que mostrou SPE em ambos os SOAs, um dos participantes com SPE apenas no SOA longo e um grande grupo sem SPE.

Swallowing in primary progressive aphasia.

BACKGROUND: Few studies have described characteristics of swallowing in primary progressive aphasia (PPA) and its variants. OBJECTIVE: To describe and characterize swallowing and eating behaviors of patients with PPA, as well as their correlates with neuropsychiatric symptoms and patterns of communication. METHODS: We studied 16 patients with PPA and 16 their caregivers. PPA was subdivided in agrammatic variant (PPA-G), semantic variant (PPA-S) and logopenic variant (PPA-L). All patients and their caregivers were screened with the following scales: "Assessment of Feeding and Swallowing Difficulties in Dementia", "Neuropsychiatric Inventory", and "Functional Outcome Questionnaire for Aphasia". RESULTS: Patients with PPA-S had diverse swallowing problems such as drooling of saliva or food, multiple swallows, delayed swallow and choking, all of which correlated with anxiety, apathy and aberrant motor behavior. Patients with PPA-G and PPA-L had choking and delayed swallow, respectively. Disturbances in eating behaviors were more frequent in the group with PPA-L, and they correlated with difficulties in patterns of communication. CONCLUSIONS: All variants showed swallowing difficulties and they were more frequent in PPA-S. Further studies with larger samples of patients are needed to better characterize swallowing problems and their consequences in the different variants of PPA.
