Brief summary

This is an observational, cross-sectional study with a control group, with the general objective of developing and evaluating a national database, unprecedented in Brazil, containing clinical, epidemiological, motor, and non-motor aspects of Parkinson's disease (PD). The database will be open and accessible to national and international researchers in order to contribute to the advancement of research related to PD. The aim is to collect data, in a paired way, from a control group and an experimental group. Data collection will include the application of questionnaires, the execution of motor activities, and clinical scales. Information that can identify the participants will be removed from the database for later storage in a repository. Quantitative, qualitative, and descriptive variables from the database will be estimated in order to characterise and contrast the groups studied. The results of this study will contribute to a better characterization of the staging of PD as a function of the epidemiological, motor, and non-motor aspects evaluated, as well as to the development of technologies and methods that can be applied in clinical practice.
