ABSTRACT

Abstract Acquired language impairments may accompany different conditions. Most recent studies have shown that there is an important relationship between language and cognitive functions, such as executive functions (EF). Therefore, we aimed to investigate which main EF components appear to have the greatest impact in the most prevalent acquired communication disorders in adults, and which neuropsychological tests are being used to evaluate them. In addition, we sought to characterize the relationship between the executive functions and language in these conditions. Working memory (WM) was the most frequently chosen cognitive measure, being evaluated by different span tasks. A relationship between WM and narrative and conversational discourse, writing abilities and grammatical comprehension was found. Other currently used cognitive tests included the Trail Making, Wisconsin, Stroop and Verbal Fluency tests. Language and EF have a complex relationship; hence, a complete assessment should reflect the dynamic processing of cognitive brain functions.


Resumo Distúrbios de linguagem adquiridas podem acompanhar diferentes quadros. Estudos recentes mostram que existe uma relação importante entre linguagem e funções cognitivas, como as funções executivas (FE). Portanto, visou-se investigar quais os principais componentes das FE parecem ter um maior impacto nos quadros com transtornos de comunicação adquiridos mais prevalentes em adultos e quais testes neuropsicológicos estão sendo mais utilizados para avaliá-los. Além disso, buscamos caracterizar qual a relação entre as funções executivas e a linguagem nesses quadros. A memória de trabalho (MT) foi a medida cognitiva mais frequentemente citada, sendo avaliada por diferentes tarefas de Span. Encontrou-se relação entre MT e discurso narrativo e conversacional, habilidades de escrita e compreensão gramatical. Outros testes cognitivos usados incluem os testes Trail Making, Wisconsin, Stroop e Verbal Fluency. Linguagem e EF têm uma relação complexa e, portanto, uma avaliação completa desses pacientes deve refletir o dinâmico processamento do funcionamento cognitivo.
