Sensory disorders and electrophysiological study in Parkinson's disease / 中华神经科杂志

Parkinson's disease (PD) is one of the most common forms of neurodegenerative diseases and increases in incidence with aging.Low mortality and high disability rates bring huge economic and psychological burden to society and families.PD manifested as motor symptoms and non-motor symptoms.Recent studies have shown that non-motor symptoms,such as sensory disorder,are the significant symptoms in early stages of PD and influence quality of life of PD patients.This review focuses on the characteristics and electrophysiological changes of sensory disorders (olfactory,visual,auditory,vestibule function,pain,etc) in PD patients to provide help for the early diagnosis,disease monitoring and efficacy evaluation of PD.
