Resumo
Behavioral variant frontotemporal dementia (bvFTD) has the clinical presentation initiated and with a predominance of behavioral changes, but people with FTD also present progressive impairment of language, often related to communicative production. However, the impact of bvFTD on language is a topic that still needs further research. In addition, research that seeks to understand language changes can contribute to the development of more effective interventions for individuals with this dementia. Thus, considering the importance of language for individuals' communication and social interaction, the general objective of this research is to analyze and describe the oral narrative of individuals with behavioral variant frontotemporal dementia in contrast to a group of individuals with Alzheimer's disease (AD) and a control group (CG) with participants without dementia. The specific objectives are i) to verify differences between groups in oral narrative performance at the micro and macrostructural levels, ii) to analyze differences between groups in verbal fluency performance, and iii) to identify associations between groups' performance in oral narrative and in tests of verbal fluency. For this, data obtained in linguistic tasks were analyzed, through the verbal fluency test (semantic and phonemic category) and the cookie theft test (oral narrative). This is a multiple case study with analysis of records collected in previous research and data obtained for this research. The sample consists of 3 groups: bvFTD (15) patients, AD (15) patients and the control group, which also has 15 participants without dementia who are matched by age and school level in relation to the other two groups. The main results showed that the behavioral variant frontotemporal dementia, despite not being an aphasic dementia, affects the linguistic performance of individuals, mainly in speech planning, stage related to the theory of mind, and in the discursive impoverishment associated with lack of communication effort. In addition, the AD group was as linguistically compromised as the bvFTD group, since these two groups did not show significant differences in the performance of the variables analyzed in this study.
