Introduction. Parkinson's disease is the fourth in neurodegenerative diseases in the world. Objective. To describe the behavior of mortality rates of Parkinson's disease in a span of 20 years (1990 to 2009) in Chile. Materials and Methods. Mortality data were obtained from the Department of Health Information and Statistics of the Ministry of Health of Chile. Deaths according to the International Classification of Diseases versions 9 and 10 were selected. Rates were adjusted by the method of direct standardization. For trend analysis of mortality rates Joinpoint Regression models were used. Results. Between 1990 and 2009 there were 4910 deaths by Parkinson's disease (2565 men and 2345 women). The adjusted mortality rate increased from 0.94 to 2.0 per 100,000 populations between 1990 and 2009. The Parkinson's disease mortality rate doubled during the study period with sex differences, being higher in men (1.19 to 2.54 per 100,000 in men versus 0.75 to 1.62 per 100,000 in women) between 1990 and 2009. Conclusion. The mortality rate for Parkinson's disease has doubled in the course of two decades. This effect could be due to greater diagnostic capacity or to a genuine increase in mortality. It is necessary to investigate the causes of such increase and of gender differences.
