Objective: To determine the rate of prevalence of PD in the region of Coquimbo, Chile.

Background: Parkinson’s disease is a common neurodegenerative disease, second after to Alzheimer’s disease, which affects approximately 1-2% of the population over 65, altering their quality of life.

Methods: Is a descriptive epidemiological study based on retrospective data from Regional records Explicit Health Guarantees (GES) and hospital medical records. All these measures were stratified by age, gender and geographical location. The total number of Parkinson’s cases was used to calculate the prevalence rates per 100,000 of the total population. Demographic data was extrapolated to 2015 using 2002 census.

Results: 581 people were registered with diagnosis of DP, establishing the prevalence rate of 76 per 100,000 inhabitants, ranging from 24-200 depending on the commune. The study population had an average age of 73 years (± 9.8), with 46% of women (p> 0.05). Were 496 people over 60 years, equivalent to 0.22% of the total population. With respect to the communities studied, the most prevalent was called Paihuano with a rate of 200 per 100,000 inhabitants. The capital of the region called La Serena, had a prevalence of 111 per 100,000 inhabitants. In over 60 years, a prevalence of 685 per 100,000 people over 60 years.

Conclusions: The figures resemble those found references in other countries but with somewhat lower rates which suggests that there is underdiagnosis or underreporting.
