Managing Advanced Parkinson Disease.

Advanced Parkinson disease (PD) is associated with treatment-related motor fluctuations and reduced ability to perform activities of daily living. Progression of non-motor symptoms and medication-induced adverse effects complicate focused approach to motor symptom management, frequently accelerating reduced quality of life. It is thus critical for clinicians to consider disease progression versus therapeutic contributions when balancing management decisions. Such an approach requires careful recognition of inflection points resulting from therapeutic decisions and should prompt consideration of reduced pharmacologic burden and increased reliance on non-pharmacologic strategies in advanced disease. The successful approach to advanced PD requires a multidisciplinary effort focused on improving the patient's and family's quality of life, sometimes requiring sacrifice of motor symptom benefit. Here, we emphasize management strategies in advanced PD, focusing on the need to balance the therapeutic approach across advancing motor symptoms, progressive non-motor features, and potential pharmacologic adverse effects.
