Pain in Parkinson’s Disease: Pathophysiology, Classification and Treatment.


Cattaneo C, Jost WH


Continuous medical progress is significantly improving the quality of health care. As a result, people are living longer than during the past century, but this has also caused an increase of the prevalence of many neurological disorders. Parkinson’s disease (PD) is the fastest growing neurological condition, with a doubling of cases reported between 1995 and 2015 and a further doubling projected by 2030. Parkinson’s disease is generally associated with characteristic motor symptoms (resting tremor, rigidity, bradykinesia and postural instability). However, patients with PD also experience many non-motor symptoms that might be at least as debilitating as the motor symptoms and which significantly impact patients’ quality of life (QoL). Pain is a frequent yet underrecognized symptom; the incidence in PD is much higher than in the general population and constitutes a silent disability that significantly contributes to a deterioration in QoL. Accurate identification of parkinsonian pain is important for its diagnosis and effective treatment. In this review, we provide an overview of the pathophysiology, classification, and management of pain in PD. We define the various modalities of chronic PD pain, suggesting possible explanations for its relationship with PD pathology, and discuss its management and currently recommended therapies.
