Background: As the 2nd most common neurodegenerative disorder, Parkinson's disease (PD) affects over 1 million Americans. Treatment is complex and may include pharmacotherapy, rehabilitative measures, and surgical intervention. A comprehensive understanding of the patient's perceptions about PD is a vital step towards improving health literacy and clinical outcomes. Methods: KnowPD is a web-based survey with Likert responses for a cross-sectional, nonrandomized study to assess patients' knowledge of PD symptoms, medications, deep brain stimulation (DBS), rehabilitation, and other factors relevant to disease management. Results: Of the 98 subjects surveyed, 90% agreed they had sufficient knowledge of PD. However, in this cohort, 82% incorrectly believed levodopa stops working as the disease progresses, 77% erroneously thought DBS improves balance and reduces falls, and, <50% could answer specific questions regarding the dosing of levodopa despite over 75% reporting managing their own medications. A majority of patients (84%) believed it was possible to live well with PD, correlating with their self-reported knowledge of the disease. Finally, patients selected electronic video (13.7%) and reading (20.0%) material, yearly symposia (20.0%), and lunch lectures (28.4%) as their preferred method of information delivery. Conclusion: Misconceptions are prevalent among PD patients, and these appear to be unrelated to gender, provider type, or education level. Identification and characterization of this knowledge gap is vital towards allocating patient education resources, and the findings described herein will form the basis for effective educational interventions.
