Although Parkinson’s disease is the second most prevalent neurodegenerative disease worldwide, its cost in Brazil – South America’s largest country – is unknown.
The goal of this study was to calculate the average annual cost of Parkinson’s disease in the city of São Paulo (Brazil), with a focus on disease-related motor symptoms.
This was a retrospective, cross-sectional analysis using a bottom-up approach (ie, from the society’s perspective). Patients (N=260) at two tertiary public health centers, who were residents of the São Paulo metropolitan area, completed standardized questionnaires regarding their disease-related expenses. We used simple and multiple generalized linear models to assess the correlations between total cost and patient-related, as well as disease-related variables.
The total average annual cost of Parkinson’s disease was estimated at US$5,853.50 per person, including US$3,172.00 in direct costs (medical and nonmedical) and US$2,681.50 in indirect costs. Costs were directly correlated with disease severity (including the degree of motor symptoms), patients’ age, and time since disease onset.
