[Extract] Communication barriers for people with Parkinson disease (PD) are embedded in the speech production of their hypokinetic dysarthria as well as their masklike affect and facial expression. Yet, most people with PD will face cognitive-linguistic impairment as well. Less is known about the latter, but it is not unexplored. Even as recently as 20 years ago, the communication difficulty of people with PD was thought solely to be the artifact of movementbased disruption of speech and voice. Linguistic processing disorder was thought to be confined to the purview of aphasia. Expansion and evolving sophistication of our methods of assessing cognitive-linguistic processes has broadened our appreciation of what can go wrong in PD. Language function is difficult to assess and describe because it is difficult to parse from the complex motor speech and cognitive abilities (e.g., attention, memory, executive function) known to deteriorate with PD. The cognitive characteristics inherent in PD are gaining attention and clarity. Stocci and Brusa (2000) report 90% of people with PD have some cognitive impairment affecting daily life, with 25% classified as severe cognitive impairment. This supports the frequent complaints of our clients with PD who report losing their train of thought, forgetting appointments, and difficulty planning the temporal sequences of a typical day.
