ABSTRACT
This study investigates discourse coherence and its relation with cognitive deficits in Alzheimer's disease (AD). Participants consisted, in two groups of individuals, 18 with AD in the moderate and moderate severe stages of cognitive decline, and 16 older adults without dementia matched by age, sex and education. Discourse tasks differed according to the presence of non-informative and informative prompts. Verbal comprehension, semantic memory, episodic memory and working memory were tested. Findings showed that global coherence was affected in AD participants. Correlations between discourse and cognitive variables were observed. The strongest correlations found related global coherence to episodic and semantic memory in the informative prompt task. Results are discussed according to clinical and theoretical implications for the understanding of discourse production in AD.
RESUMO
Este estudio investiga la coherencia del discurso de las personas con enfermedad de Alzheimer (EA) y las posibles relaciones con déficits cognitivos. Los participantes fueron 18 personas con EA en las fases moderada y severa-moderada y 16 idosos sanos pareados por edad, educación y género. Dos tareas discursivas fueron usadas, una sin ayudas informativas y otra con ayudas informativas. La comprensión verbal, la memoria semántica, la memoria episódica y la memoria de trabajo fueron evaluadas. Los resultados mostraron coherencia global afectada en participantes con EA. Se observaron correlaciones entre el discurso y las variables cognitivas, especialmente entre coherencia y memoria episódica y semántica. La discusión debate la evaluación clínica discursiva y sus implicaciones para entender la comunicacion de personas con Alzheimer.
