The Cognitive Substrates of Action Fluency: A Multivariate Analysis in Parkinson's Disease

AF performance in PD-ND reflects domain-general executive-generative mechanisms rather than an isolated verb semantic deficit. Clinically, AF should be interpreted as an integrative measure of executive control. Incorporating a multidimensional fluency battery may improve diagnostic sensitivity and inform targeted interventions for cognitive-communication impairments in PD.

Abstract

AF performance in PD-ND reflects domain-general executive-generative mechanisms rather than an isolated verb semantic deficit. Clinically, AF should be interpreted as an integrative measure of executive control. Incorporating a multidimensional fluency battery may improve diagnostic sensitivity and inform targeted interventions for cognitive-communication impairments in PD.
