Abstract
Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor symptoms bradykinesia, rigidity, tremor and postural instability. However, PD is usually associated with non-motor symptoms (NMS) that include olfactory and gustatory dysfunctions, neuropsychiatric symptoms such as apathy, anxiety and cognitive impairment, sleep problems, and autonomic dysregulation. Few data are available regarding the contribution of NMSs and motor symptoms on body weight change in PD patients. The aim of this study was to assess the effect of olfactory and gustatory dysfunction, apathy, fatigue and motor symptoms on weight regulation in PD patients.
