ABSTRACT
ABSTRACT. Despite the significance of discourse impairments, they have not been thoroughly investigated in Persian-speaking patients with Alzheimer's disease (AD).

Objective:

the aim of this study was to perform a multi-level analysis of narrative discourse in Persian-speaking patients with mild AD and to compare them with healthy elderly.

Methods:

the study included 14 older adults with mild AD and a matched group of 14 healthy elderly. Using a storytelling task based on serial pictures, both macro- and micro-linguistic aspects of narrative discourse were assessed. Cohesion ratio and coherence were investigated as macrolinguistic dimensions of discourse. The studied microlinguistic features included syntactic complexity and verbal errors (mostly involving phonological and semantic paraphasias and mazes). Severity of AD was determined using the Cognitive Dementia Rating (CDR).

Results:

there were significant differences between the groups regarding cohesion ratio (0.9 ± 0.34 vs. 1.29 ± 0.45, p = 0.02) and coherence scores (2.43 ± 0.41 vs. 3.02 ± 0.81, p = 0.03). Verbal errors and syntactic complexity did not differ significantly between the groups.

Conclusion:

Persian-speaking patients with mild AD show macrolinguistic impairments in producing discourses based on picture description. Therefore, intervention protocols should focus on the ability to organize information on a specific subject and also to connect sentences produced using appropriate cohesive ties.
RESUMO
RESUMO. Apesar da significância das deficiências discursivas, elas não foram completamente investigadas em pacientes de fala persa com doença de Alzheimer (DA).

Objetivo:

o objetivo deste estudo foi desenvolver uma análise multinível do discurso narrativo em pacientes de língua persa com DA leve e compará-los com idosos saudáveis.

Métodos:

o estudo incluiu 14 idosos com DA leve e um grupo pareado de 14 idosos saudáveis. Usando uma tarefa narrativa baseada em imagens seriais, os aspectos macro e microlinguísticos do discurso narrativo foram avaliados. Coesão e coesão foram investigadas como dimensões macrolinguísticas do discurso. As características microlinguísticas estudadas incluíram complexidade sintática e erros verbais (incluindo principalmente parafasias e labirintos fonológicos e semânticos). A gravidade da DA foi avaliada por meio do Cognitive Dementia Rating (CDR).

Resultados:

houve diferenças significativas entre os grupos quanto ao coeficiente de correlação (0,9 ± 0,34 vs. 1,29 ± 0,45, p = 0,02) e escores de coerência (2,43 ± 0,41 vs. 3,02 ± 0,81, p = 0,03). Erros verbais e complexidade sintática não foram significativamente diferentes entre os grupos.

Conclusão:

pacientes de língua persa com DA leve apresentam comprometimento macrolinguístico em produzir discursos baseados na descrição de figuras. Portanto, os protocolos de intervenção devem enfocar sua capacidade de organizar informações sobre um assunto específico e também conectar suas sentenças produzidas por laços coesos apropriados.
