Abstract
Parkinson's disease (PD), one of the most common neurodegenerative diseases, is characterized by motor symptoms, like static tremor, rigidity, bradykinesia and postural balance disorder, and some non-motor symptoms such as cognitive impairment, sleep disturbance, depression, emotional problems. The pathogenesis of PD is related to the synthesis and metabolism of dopamine in the brain. In recent years, more and more studies have indicated that the non-dopaminergic nervous system plays an important role in the pathogenesis of PD. The EFNS and the MDS-ES refer that PET can assist the diagnosis of PD in clinical application, thus, PET provides powerful tools for PD. We reviewed the application for the progression of PET imaging in PD. Key words: Parkinson's disease; Positron emission tomography; Motor symptom; Cognitive impairment
