Word-finding difficulties in Parkinson's disease: Complex verbal fluency, executive functions and other influencing factors.

What is already known on the subject Varying degrees of word-finding difficulties are a common symptom in PD and may affect everyday communication. Discreet word-finding difficulties can be hard to detect with the established language assessment tools. What this paper adds to existing knowledge This study adds insights into how PwPD perform on different types of COWATs compared with a control group. It also sheds light on the relationships between a novel, more cognitive complex COWAT and executive functions in PD. What are the potential or actual clinical implications of this work? More cognitively complex COWATs can contribute significantly to the assessment of discreet word-finding difficulties, but it is important to include a thorough anamnesis regarding language and communication in PwPD.
