The purpose of this study is to explore the relationship between the self-reported executive functions (EFs) in persons with Parkinsons disease (PD) and their significant others. Executive functions include basic cognitive processes such as attention, inhibition, working memory, and cognitive flexibility. As this proposed study will test not only cognitive functioning, but specific aspects of it (i.e., EFs) without excluding persons with PD who have identified cognitive impairments, outcomes gathered could provide valuable information to better assist all types of persons with PD. Comparing their self-reported EFs to the EF ratings completedy by their signifiant others can help determine if a disparity exists between self-perceptions and actual observed EF abilties. This study would assess EFs through inhibition responses of participants via computerized versions the Comprehensive Executive Function Inventory-Adult Self-Report and Observer forms.
The investigators are conducting a study to compare the self-reports of executive functions (that is to say, what role cognitive processes such as working memory and attention) in persons with Parkinson's Disease to the reports of executive functions completed by their significant others.~To conduct this study, the investigators need the participation of persons who are diagnosed with Parkinson's Disease and their significant others.
