Abstract(s) :

(Anglais) Objective: The aim of this article is to examine the presence of anomia in Parkinson Disease as well as the cognitive difficulties related to the patients’ word naming impairment, either linguistic or executive. Method: 11 non-demented patients with Parkinson Disease (PD) were presented a picture naming task. Associate language difficulties were examined by analysing the effects of word frequency and length on naming performances as well as the results in two semantic tasks. Executive capacities were assessed with working memory, inhibition, flexibility and updating tasks. Finally, patients’ cognitive processing speed as well as the presence of a depression were also examined. Results: PD patients presented lower scores in the picture naming task, corroborating the presence of anomia in PD. We also showed difficulties in semantic processing as well as in the executive tasks assessing short-term and working memory, inhibition and flexibility. Finally, we also highlighted higher scores at the depression scale in the group of PD patients. Conclusions: The results in this study reveal the presence of naming difficulties in PD and suggest that they have a multi-determined origin.
