Treatment of Parkinson's disease: a survey of patients and neurologists.

Background: The treatment of Parkinson's disease (PD) is complex and highly individual. The choice between available treatment options depends on clinical characteristics such as the patient's age, disease severity and presence of comorbidities, lifestyle characteristics and preferences, costs of different medications and awareness and perception of available treatment options, and education of the treating physician. The impact of PD treatment regimens on patients' health-related quality of life (QOL) is also an important healthcare feature.
