Parkinson's disease (PD) is a chronic degenerative disease of the central nervous system that evolves slowly and progressively and is characterized by bradykinesia, muscle rigidity and resting tremor among other motor signs and symptoms 1,2 . Quality of life is significantly impaired not only by motor symptoms, but also by non-motor symptoms such as depression, anxiety, pain, constipation, hyposmia and sleep disturbances 3,4 . There are few studies on the incidence and prevalence of PD in Brazil; however, the most recent study shows that the disease affects 3.3% of Brazilians over the age of 60 years 4 . One of the concerns when treating PD patients is to improve their quality of life. This includes their physical, functional and emotional well-being, their degree of independence and their family relationships, as well as social, economic and political aspects of their lives 5,6 . A decline in quality of life in individuals with PD has been associated with worsening motor symptoms and the combination of neurodegenerative phenomena, psychological suffering and stigma associated with the disease
