帕金森病患者体重减轻及其机制研究进展

摘要

帕金森病(PD)患者的体重减轻是常见的非运动症状之一,可在PD运动症状之前出现并与病情进展相关,但较少被临床医生重视.帕金森病患者体重减轻病理生理机制复杂,本文从多巴胺能系统、能量稳态失衡、摄食行为的中枢调节机制和代谢神经内分泌调节机制方面综述帕金森病患者体重减轻的机制.%Weight loss is common in non-motor symptoms in Parkinson disease (PD).It may predate motor symptom onset,and may be associated with the development of disease.However,it was less accounted of clinically.The pathophysiology of weight loss in PD is very complicated.This review discusses the pathogenesis of PD weight loss from dopaminergic dysfunction,energy expenditure/intake imbalance,central mechanisms of feeding behavior regulation,and neuroendocrine abnormalities.
