Perception, Cognition, and Gait in Parkinson’s Disease


The investigators are examining how aspects of daily function are perceived in persons with PD and in those who interact with them on a regular basis. If eligible, participants will receive a set of online questionnaires by email. The questionnaires will take about 1 hour to complete, and can be done at the participant's convenience. The investigators are looking for volunteers who have a diagnosis of Parkinson's disease without dementia (age 40 or older and proficient English speakers). If a spouse, family member, significant other or other close associate is available (age 18 or older, proficient English speakers), the investigators will send them questionnaires as well. There is no monetary or other compensation for this study. For more information, please contact the Vision and Cognition Laboratory at or 617-358-1377.
