“…Consistent with other reports (Beatty & Monson, 1989;Hanley et al, 1990), the PDND group did not differ from an age and education matched control group on any of the fluency tasks, suggesting that action fluency is not sensitive to the early pathophysiological changes of PD. Given that differences in fluency performance between PDND and PDD are most apparent on the action fluency task, there is suggestion that action fluency may be an early indicator of the conversion from PD to PD with associated dementia.…”

“…Some studies have reported no lexical or semantic fluency deficits among cognitively intact PD subjects relative to control subjects (Beatty & Monson, 1989;Hanley, Dewick, Davies, Playfer, & Turnbull, 1990;Tröster et al, 1998), whereas others have identified deficits in both lexical and semantic fluency in PD subjects (Bayles, Trosset, Tomoeda, Montgomery, & Wilson, 1993;Flowers, Robertson, & Sheridan, 1996). Still others have identified deficient semantic fluency but preserved lexical fluency (Auriacombe et al, 1993;Beatty & Monson, 1989;Raskin, Sliwinski, & Borod, 1992).…”

Previous research suggests that lexical and semantic verbal fluency are differentially sensitive to the effects of cortical and subcortical dementias, but little is known about action fluency performance in dementias. The present study compared lexical, semantic, and action fluency in groups of patients with Parkinson's disease (PD) with and without dementia and an elderly control group. Findings revealed an interaction between fluency type and subject group. Although the demented PD (PDD) group performed significantly more poorly than their non-demented counterparts and normal controls on all three fluency tasks, a disproportionate disparity in scores was noted on the action fluency task. The findings suggest that action fluency may be particularly sensitive to PD-associated dementia and may be an early indicator of the conversion from PD to PDD. As reported elsewhere, PD without dementia was not associated with significant impairment on any of the fluency tasks.

“…This is in accordance with the study by Gurd and Ward [26], who found no relation between scores of 12 fluency tasks and the rate of speak ing in PD. Although the present study did not compare PD patients and CS, our results fit those of Hanley et al [27], who found that differences in fluency between PD and CS disappeared when differences of age and verbal ability were partialled out. Just like us, they found no association between fluency performance and depression.…”

Abstract-In the present study, we investigated the association of two executive functions with disease characteristics in Parkinson's disease (PD), especially with severity of motor symptoms. We operationalized two executive functions, viz. fluency and cognitive shifting, each in a number of tests with heterogeneous materials, but with an identical format. We calculated the correlations between test performance and disease characteristics, including the factor scores of the Unified Parkinson's Disease Rating Scale (UPDRS). The results of this study show that only cognitive shifting was consistently associated with the severity of motor symptoms in PD, in particular with rigidity. None of the fluency tests had a significant association with severity of motor symptoms. The present study indicates that PD, as reflected by the severity of motor symptoms, is not associated with a general decrease in executive function. In spite of the fact that both are executive functions and both require generation of items, fluency and cognitive shifting are differentially related to PD.

“…The pauses that occur when the patient stops to recall words lead to hesitations and pauses in their speech. This decreased verbal fluency may be related to aging or may be a symptom of Parkinson's disease (Gurd and Ward, 1989, Hanley, Dewick, Davis, Playfer, Turnbull, 1990, Scott and Caird, 1984. Regardless of the origin of the disorder, speech-language therapy can facilitate word retrieval by having patients recall words in categories or by making word associations.…”
