ABSTRACT
Pain is highly prevalent in Parkinson’s disease (PD), representing an important source of distress and disability for many patients. For most individuals with PD, the clinical features of bradykinesia, rigidity, tremor, postural instability, dementia, and other impairments dominate the clinical picture. Most patients, however, when questioned directly, will also report painful symptoms or chronic discomfort resulting directly from their PD, or exacerbated by it. In a minority of patients with PD, pain is so severe and intractable that it overshadows the motor symptoms of the disease.
