Abstract: background: modern concepts on the neuropsychological bases of language consider that its network has a direct relation with the support systems such as attention and memory. semantic memory constitutes the basis of knowledge, communication and learning. semantic knowledge is consolidated with the exposure to information and the possibility to integrate information. thus, aging and literacy can be associated to semantic knowledge. aim: to analyze in normal brazilian adults the interference of literacy through the performance in a semantic test. method: 56 normal brazilian adults, 20 males and 36 females, with ages between 20 and 56 years and literacy between 1 and 20 years. participants were divided in two groups according to years of literacy: group 1 (n = 31) with 1 to 8 years and group 2 (n=25) with more than 8 years. the semantic test consisted on the presentation of questions related to 10 pictures. these questions involved: category, physical traces and function. after the questions, the naming of the pictures was requested. results: the level of literacy had an influence on the performance of the participants. there were differences between the groups regarding the judgment of the semantic traces and in the naming task: group 2 presented better scores in most of the tasks. negative questions presented a higher number o errors. the qualitative analyses of the answers obtained in the naming task indicate that the animated figures presented a higher number of deviant answers, with a higher occurrence of substitutions by a coordinated answer. conclusion: it was possible to observe that low literacy levels had a negative influence on the performance presented in tasks involving semantic knowledge, judgment of traces and naming, particularly when involving animated pictures.
Contribui??es da Análise Conversacional ao estudo do traumatismo craneo-encefálico: relato de um caso
Steiner, Véronique Agnes Guernet;Mansur, Letícia Lessa;
Revista da Sociedade Brasileira de Fonoaudiologia , 2008, DOI: 10.1590/S1516-80342008000100014
Abstract: the persistence of communication impairments in individuals who sustained a traumatic brain injury requires the use of sensitive tools to evaluate the linguistic-cognitive problems they present, aiming at their reintegration in society. this single case study investigates the contributions of conversation analysis to the evaluation of the pragmatic abilities of a 27 year-old man who sustained a severe traumatic brain injury. it analyses a spontaneous conversational interaction through the study of the collaborative mechanism of turn-taking, topic management and repairs, comparing the results of this analysis with formal language tests. it discusses the contributions of this approach to develop intervention. while formal tests did not indicate the presence of language difficulties, the conversation analysis allowed, through the analysis of the sequence of turns and of the mutual reactions of both the interlocutors, the identification of communicative problems and the observation of how the speakers dealt with them. the results of this study revealed that conversation analysis is a sensitive approach to capture the linguistic-cognitive deficits caused by traumatic brain injury, providing concrete elements to be used in therapy in order to emphasize, in an organized way, the kind of discourse most used in daily life.
Thalamus and language: interface with attention, memory and executive functions
Radanovic, Marcia;Azambuja, Mariana;Mansur, Letícia Lessa;Porto, Cláudia Sellitto;Scaff, Milberto;

Abstract: subcortical structures are in a strategic functional position within the cognitive networks. their lesion can interfere with a great number of functions. we studied six patients with thalamic vascular lesions (three left sided, two right sided and one bilateral), to characterize their repercussion in the communicative abilities and the interface between language alterations and other cognitive abilities, as attention, memory and frontal executive. all patients were evaluated through a functional interview (discourse analysis), and the following batteries: boston diagnostic aphasia examination, boston naming test, token test, benton visual retention test, trail making, wisconsin card sorting and frontal scripts. all patients performed mri and five underwent spect. results show that these patients present impairment in several cognitive domains, especially attention and executive functions (working memory, planning and self-monitoring); those with right lesions have an additional visuospatial impairment. such alterations interfere with language abilities, and this fact must be considered in the rehabilitation efforts.

Abstract: subcortical structures are in a strategic functional position within the cognitive networks and their lesion can interfere with a great number of functions. in this study, we describe fourteen subjects with exclusively subcortical vascular lesions (eight in the basal ganglia and six in the thalamus) and the interrelation between their language alterations and other cognitive abilities, as attention, memory and frontal executive functions. all patients were evaluated through the following batteries: boston diagnostic aphasia examination, boston naming test, token test, benton visual retention test, trail making, wisconsin card sorting test and a frontal scripts task. all patients underwent mri and twelve underwent spect. results show that these patients present impairment in several cognitive domains, especially attention and executive functions. these alterations affect language abilities, and this fact must be considered in the rehabilitation efforts.
Linguagem e cogni??o na doen?a de Alzheimer
Mansur, Letícia Lessa;Carthery, Maria Teresa;Caramelli, Paulo;Nitrini, Ricardo;
Psicologia: Reflex?o e Crítica , 2005, DOI: 10.1590/S0102-79722005000300002
Abstract: clinically, alzheimer's disease is defined by cognitive changes. among them, language has frequently been the focus of studies and although there is a consensus about the prevalence of semantic alterations and about the evolution of linguistic symptoms, it has still not yet been possible to clarify the nature of certain alterations. recent studies have added data to the classic knowledge about loss of cognitive abilities and its interaction with language, as is the case of alterations in working memory. our objective is to revise and update the literature about language in alzheimer's disease and, particularly, research conducted with brazilian population, emphasizing its contribution to the knowledge in multiple areas involved with this subject.
Biomecanica ultra-sonográfica da degluti??o: estudo preliminar
Lynch, Cinthya da Silva;Chammas, Maria Cristina;Mansur, Letícia Lessa;Cerri, Giovanni Guido;

Abstract: objective: to evaluate, by means of ultrasonography, the spatial parameters of the hyolaryngeal complex in the deglutition dynamics as well the correlation between age and effects. materials and methods: the present prospective and quantitative study included 39 healthy men and women in the age range between 20 and 70 years (mean, 45.56; standard deviation, 14.53). the swallowing biomechanics corresponding to the measurement of the distance between the upper portion of the hyoid bone and the upper rim of the thyroid cartilage at the moment of maximum laryngeal elevation was evaluated. measurements were performed with the ingestion of pasty or liquid food. results: the variation of the distance between the hyoid bone and the larynx presented a positive association with aging only in the swallowing of pasty food that requires a higher lingual propulsive activity than liquid food does. conclusion: an increase in the distance between the hyoid bone and the larynx, corresponding to a poorer laryngeal elevation, may occur during the deglutition of pasty food as a result of aging, a process where a decrease in functional reserves is observed even in healthy individuals. ultrasonography can detect the swallowing behavior related to foods consistency, demonstrating the diagnostic potentiality of this method in the evaluation of the deglutition.
