Abstract
Background: Nonmotor symptoms in Parkinson's disease are frequent and affect health-related quality of life of patients. The severity and domains of nonmotor symptoms involved in Parkinson's disease and normal aging have not been compared before.Methods: We performed a prospective case-control study to assess the frequency and severity of nonmotor symptoms in patients with Parkinson's disease (n = 174) and age-matched normal controls (n = 128) using the Non-Motor Symptoms Scale.Results: Nonmotor symptoms in Parkinson's disease were ubiquitous, more frequent, and more severe than in normal aging, particularly in women. Cardiovascular, mood/cognition, and perceptual problems/hallucinations domains were rarely involved in age-matched controls. Age had no effect and sex some influence on nonmotor symptoms in Parkinson's disease. In contrast, in controls, nonmotor symptoms increased with age, and sex had no effect.Conclusions: Nonmotor symptoms in Parkinson's disease differ from those in aging in frequency, severity, sex predilection, and domain involvement.
