Parkinson’s Disease (PD) is a progressive neurodegenerative disorder that affects 1% of the world population over the age of 65—anywhere from four to six million people (National Parkinson Foundation, 2010). Although most people identify PD as a movement disorder, cognitive deficits are also present. Poor performance on tasks such as set shifting, internal control of attention, and sequencing is commonly reported by PD patients (Stout & Johnson, 2005), as are visual and verbal memory impairments (Moody, Bookheimer, Vanek, & Knowlton, 2004). Visuospatial skills are also problematic, including depth perception, spatial orientation, and spatial organization (Bowen, Burns, Brady, & Yahr, 1972).
