“…The results confirm the findings of studies that investigated global coherence and topic changes in AD discourse 12,13 . These results corroborated with the idea that there may be a macrostructural disorder that affects the discourse of individuals with AD already in the beginning of the disease 11 .…”

“…The progressive deterioration of the long-term memory in the early stages of AD leads to losses of semantic knowledge. This decline, as well as working memory deficits, interact with difficulties in establishing meaning relations in a more global sense, which would provide meaning to the discourse as a whole 13 . The discursive difficulties observed were probably influenced by the complexity of the visual input used, which consisted of a stimulus with twelve figures in temporal sequence.…”

“…The concepts of local and global coherence originate from the idea that discourse propositions are organized according to the macrostructure (main ideas) and the microstructure (less relevant ideas) 10 . Several investigations show that the discourse of participants with AD presents impairments in global coherence, with local coherence being preserved until later stages of the disease [11][12][13] . However, there are still little research devoted to observe the effects of the type of discourse task over discourse coherence.…”

Financial support: foreign doctoral internship scholarship from CAPES Conflict of interest: non-existent INTRODUCTIONDementia is characterized by the presence of cognitive or behavioral symptoms that interfere in daily activities and represent a decline of previous level of functioning and performance. People with dementia present a cognitive deterioration, ABSTRACT Purpose: to investigate discourse in Alzheimer's disease (AD) using a picture narrative task; to examine possible difficulties in the expression of knowledge and the relationship between discourse and cognition. Methods: the design of the study was transversal, using quantitative comparison of groups. The clinical sample consisted of eighteen subjects with AD, eight of them with moderate cognitive decline (GDS 4) and ten with moderate-severe cognitive decline (GDS 5); the control group consisted of sixteen subjects without neurological or psychiatric disorders. All were matched for gender, native language, age and education and subjects underwent cognitive assessments. The discourse task consisted of a picture narrative of the tale "Little Red Riding Hood." Results: participants with AD had lower overall coherence scores and more difficulties in the expression of knowledge than subjects without AD. Discourse deficits correlated with performance on cognitive measures. The GDS 4 and GDS 5 groups differed in local coherence scores. Conclusion: discourse of subjects with AD was characterized by failure in coherence and informativeness, which related strongly with their cognitive deficits.

“…Nos estudos de Dijkstra (Dijkstra et al, 2004;Dijkstra et al, 2002), os participantes com DA, em estágios leve, moderado e severo, foram entrevistados por auxiliares de enfermagem em uma residência geriátrica. Os temas da conversação introduzidos pelos auxiliares de enfermagem consistiram na família, na vida e no dia do paciente.…”

“…Destaca-se a ausência de elementos importantes para a compreensão do discurso pelo interlocutor (Ripich & Terrel, 1988), demandando deste último um maior número de interrupções para pedir esclarecimentos (Laine, Laakso, Vuorinen, & Rinne, 1998). De acordo com Dijkstra e colaboradores (Dijkstra, Bourgeois, Allen, & Burgio, 2004;Dijkstra, Bourgeois, Petrie, Burgio, & Allen-Burge, 2002), são observados níveis de desordens discursivas marcadamente distintos nos estágios leve, moderado e severo da doença de Alzheimer.…”

ResumoPessoas com doença de Alzheimer apresentam dificuldades discursivas evidentes que demandam avaliação e intervenção. Para tanto, é necessário compreender as diferentes demandas de distintas tarefas discursivas. Este artigo revisa os principais estudos sobre o discurso de pessoas com doença de Alzheimer, descrevendo o desempenho discursivo dessa população em tarefas discursivas classificadas de acordo com os estilos de input fornecidos. São descritos estudos que propuseram o uso de tarefas com input neutro, conversações naturalísticas, input diretivo e facilitador e tarefas com figuras (narrativa e descrição). São discutidas as diferenças entre as tarefas discursivas, abordando habilidades discursivas afetadas e preservadas na doença de Alzheimer. São feitas considerações sobre a investigação e as aplicações clínicas das diferentes tarefas discursivas para a avaliação e a intervenção da comunicação de pessoas com doença de Alzheimer. Palavras-chave: Doença de Alzheimer; Comunicação; Tarefas discursivas; Estilos de input. AbstractPeople with Alzheimer's disease (AD) have discourse deficits which demand evaluation and intervention. For this reason, it is important to understand the different demands of different discourse tasks. This article reviews the main studies on the discourse of people with Alzheimer's disease, describing the performance of such population in discourse tasks which are classified according to their input style. Studies which used neutral input, naturalistic conversations, directive and facilitative input, and tasks which used visual stimuli to elicit narrative and descriptive discourse were described. Differences between discourse tasks focusing on preserved and affected discourse abilities in people with Alzheimer's disease were discussed. Finally, research on discourse tasks for those with Alzheimer's disease and their application in the evaluation and intervention of communication in AD is considered.
