Semantic and phonological oral naming tests (ONT) are often used to assess cognitive dysfunction in PD. In general, results have shown that patients with PD produce fewer words in both tasks than matched control individuals while the qualitative analyses of word production in PD patients are contradictory. While some studies have shown that the average size of phonemic and semantic clusters are not reduced in PD, others have reported that switching and clustering are decreased in PD patients. These contradictory results could be partially explained by the different evaluation criteria used (semantic and phonologic). In order to minimize this factor, we used an unconstrained oral naming task (UON) where a group of non-demented PD and a group of control individuals, matched for gender, age and education, were invited to produce words within a limited time period (150 second), without having to respect any production criterion. Different aspects of word production were analyzed, such as number of words, frequency, familiarity, concreteness and number of words produced within each 30-second period. Participants also performed a short neuropsychological battery and analysis production was correlated with their profile. Results showed that switching is impaired in PD patients while clustering is not. The results of this qualitative analysis are consistent with the possibility that the oral naming production of Parkinson's patients reflects a disruption of frontal-basal ganglia circuits mediating set-shifting abilities.
