Epidemiology of Parkinson’s Disease in Chile

Parkinson's disease (PD) is one of the most common neurodegenerative disorders. There is no epidemiological description of PD in Chile and not many descriptions in Latin America. This study aims to describe the incidence and prevalence of PD in Chile.The study group was the population on the public health system in Chile between 2010 and 2018 that were registered in the GES system as having PD. Crude and standardized prevalence and incidence were calculated with a 95% confidence interval.33,345 patients were found in the register as confirmed cases with PD. The crude incidence in 2018 was 23.7/100,000; the crude prevalence in 2018 was 160.7/100,000. The male-to-female ratio was 1.03.The prevalence and incidence observed in the Chilean population are consistent with studies from other countries.
