Parkinson's disease (PD) is the most common neurodegenerative disease, after Alzheimer's. The increase in its prevalence is due to a combination of factors. In 2016, over 6.1 million cases were registered and it is believed that this value will double by 2050, which is why it is considered a public health problem.

To carry out a literature review about the psychosocial aspects associated with PD, considering their importance as possible prodromal markers of the disease.

A bibliographic search was made taking into account the material generated in the last 15 years, and using the databases PubMed, SciELO, Dialnet and Redalyc.

Research on PD primarily focus interest on the characteristics, symptoms, diagnosis and treatment. It´s observed the need of developing more scientific studies to obtain evidence regarding the sociodemographic, psychosocial and geographical characteristics of patients with PD. In adition, it’s important to increase the knowledge about the impact of depression and anxiety over PD. They can become decisive when diagnosing, but also for facing and sustaining an adequate treatment to achieve the patient’s well-being on physical, emotional and social aspects. Studies on Quality of life related to health and PD are also important in this regard.
