Influence of brain lesion and educational: background on language tests in aphasic subjects

Impacto da lesão e da escolaridade na avaliação de linguagem em sujeitos afásicos

Abstract

In language assessment, several socio-demographic variables must be taken into account. Objectives: To characterize the performance of aphasic patients with different educational background on language tasks and to compare their performance to that of individuals with no language disorders.Methods: Thirty aphasic patients and 30 healthy individuals were selected. Patients were divided into two groups according to educational level: A (1-4 years) n=15 and B (5-11 years) n=15. Age ranged from 27 to 78 years. All subjects were submitted to the Montreal Toulouse language assessment protocol. The pertinent statistical tests were applied. Results: Educational level interfered in the linguistic performance of normal subjects but not in that of aphasic subjects, whose performance was influenced more by the lesion. Conclusions: The present study can contribute toward greater understanding of the influence of lesions and educational background on the language performance of aphasic subjects.

Key words:

Resumo

Para a avaliação de linguagem várias variáveis sócio-demográficas devem ser levadas em conta Objetivo: Estudar e caracterizar o desempenho de sujeitos afásicos com diferentes escolaridades em tarefas lingüísticas e comparar o desempenho destes pacientes com indivíduos sem alteração de linguagem. Métodos: Foram selecionados 30 pacientes afásicos e 30 indivíduos, pareados com mesma idade, sexo e escolaridade. A escolaridade variou em duas faixas de acordo com o nível educacional: A (1-4 anos) n=15 e B (5-11 anos) n=15. A idade variou entre 27 e 78 anos. Todos os sujeitos foram submetidos ao protocolo de avaliação de linguagem Montreal Toulouse. Foram aplicados os testes estatísticos pertinentes. Resultados: A escolaridade interferiu no desempenho lingüístico de sujeitos normais, mas não de sujeitos afásicos, sendo para este grupo a lesão mais impactante e determinante do desempenho. Conclusões: Acreditamos que o nosso estudo contribua para a uma melhor compreensão do impacto da lesão e da escolaridade no desempenho lingüístico de sujeitos afásicos.
