[Progress on the mechanism and treatment of Parkinson's disease-related pathological pain].

Abstract

Parkinson's disease (PD) is a common neurodegenerative disease characterized by motor symptoms, including bradykinesia, resting tremor, and progressive rigidity. More recently, non-motor symptoms of PD, such as pain, depression and anxiety, and autonomic dysfunction, have attracted increasing attention from scientists and clinicians. As one of non-motor symptoms, pain has high prevalence and early onset feature. Because the mechanism of PD-related pathological pain is unclear, the clinical therapy for treating PD-related pathological pain is very limited, with a focus on relieving the symptoms. This paper reviewed the clinical features, pathogenesis, and therapeutic strategies of PD-related pathological pain and discussed the mechanism of the chronicity of PD-related pathological pain, hoping to provide useful data for the study of drugs and clinical intervention for PD-related pathological pain.
