Objective: The researchers aim to determine the prevalence of the Parkinson Disease in a locale and explore the possible predisposing factors on the development of the disease.

Background: Parkinson disease (PD) is a neurodegenerative disorder affecting the central nervous system caused by the death of dopaminergic cells in the ventral region of the pars compacta of the substantia nigra. The subsequent lack of dopamine causes movement-related disorders including tremors, rigidity, hypokinesia, and postural instability. Development of the disease is through certain environmental, hereditary, and genetic factors. In the Philippines, PD is a rarely seen disorder and establishing a prevalence study has been difficult for neurologists. Prevalence of the disease in the country has been estimated to be less than 1% based on a 2007 study conducted by the Philippine Neurologic Association but without ascertainment of cases.

Method: The research was conducted through a two-phase descriptive design, consisting of a screening method via questionnaires followed by case ascertainment. Point prevalence rate was used for statistical treatment.

Results: It was found that out of three hundred sixty-five respondents in the community, there were two cases of PD – one male and one female case.

Conclusion: Thus, the prevalence of PD was 0.55% or approximately 0.1%, which is consistent with current literature noting the nationwide prevalence of PD in the Philippines.
