“… 15 27 28 Literature documented that category-specific deficits may occur due to different brain systems, although it is still being debated. 29 30 In our study, we observed comparable accuracy for the 2 categories in the test, suggesting that the animal and fruit categories can be used interchangeably for the detection of AD and MCI. In contrast to semantic fluency which produces items in attribute relationships, association fluency measures the ability to generate semantically associated words that are in coordinate relationships.…”

Background and Purpose Verbal and nonverbal fluency tests are the conventional methods for examining executive function in the elderly population. However, differences in impairments result in fluency tests in patients with mild cognitive impairments (MCIs) and Alzheimer’s disease (AD) and in neural correlates underlying the tests still necessitate concrete evidence. Methods We compared the test performances in 27 normal controls, 28 patients with MCI, and 20 with AD, and investigated morphological changes in association with the test performances using structural magnetic imaging. Results Patients with AD performed poorly across all the fluency tests, and a receiver operating characteristics curve analysis revealed that only category fluency test discriminated all the 3 groups. Association, category, and design fluency tests involved temporal and frontal regions, while letter fluency involved the cerebellum and caudate. Conclusions Category fluency is a reliable measure for screening patients with AD and MCI, and this efficacy might be related to morphological correlates that underlie semantic and executive processing.

“…Midterm cognition was assessed using the Memory Impairment Screen (MIS) 22,23 and the Category Fluency Test (CFT). 24 The MIS has been validated as an efficient, reliable, and valid screening for dementia and Alzheimer's disease, and the CFT has been validated and used in studies of Alzheimer's disease in both literate and illiterate patients. An individual was defined as being cognitively impaired on the basis of the MIS criteria if they scored 4 or less.…”

“…Because it is a health-related area, research methodologies used in this field tend to adhere to methods that are more quantitative, which offer an illusion of objectivity, based on the control of "variables" and the alleged homogeneity of subjects (CHIARI et al, 2012 1 ; TING et al, 2013;BEFI-LOPES et al, 2014;CAPELLINI, CÉSAR and GERMANO, 2015). In research on diagnosis, for example, the statistical norm that guides the tests in question does not reflect the state of the subjects under evaluation, but it ends up imposing over them authoritatively, hampering their position toward the evaluation (FRIEDMAN, 2010).…”

The entrance of human sciences into Speech Therapy research in Brazil can still be considered recent. Research methodologies used in this area tend to adhere to methods that are more quantitative than qualitative. The goal of this study is to discuss the conceptual basis of Bakhtin's enunciative-discursive theory and its practical implementation for Speech and Language Pathology Therapy. For this purpose, we present dialogical episodes analyzed in light of Bakhtin's perspective. The results show that, when social, cultural and subjective aspects are taken into account, this kind of analysis may bring new insights to understanding linguistic processes and the various possibilities of language as far as pathologies are concerned. Thus, one may not only understand language holistically, but also envisage strategies that subjects with and without pathologies employ to maintain their status as speakers/authors. KEYWORDS: Qualitative Research; Speech Therapy; Enunciative-Discursive Perspective RESUMO A entrada das ciências humanas nas pesquisas da Fonoaudiologia no Brasil ainda pode ser considerada recente.
