Study of Electroretinogram and Oral Bacteria in Parkinson’s Disease: A Study of Markers in Parkinson’s Disease

Principal Investigator:

Martin Lévesque, Ph. D, researcher at Centre de recherche CERVO

Co-investigators:

Marc Hébert, Ph. D, researcher at Centre de recherche CERVO

Emmanuelle Pourcher, MD, neurologist et clinical-researcher at the Institut universitaire en santé mentale de Québec

Nicolas Dupré, MD, neurologist et clinical-researcher at the University Hospital Center of Québec

Site:

Centre de recherche CERVO, Québec city

Objectives:

To study the activity of the eye retina in the light and analyse oral bacteria and antibodies in the saliva of people with Parkinson’s disease. All in order to identify new diagnostic tools.

For this project, we will recruit 40 participants, men and women: 20 participants with Parkinson’s disease and 20 participants in good health.

Procedures:

The participation consists of two visits at the CERVO research center, for a total of 4 hours.

During the second visit, the participant will undergo an electroretinography (also called “ERG”), give saliva plus a sample of oral bacterial. ERG is commonly used in ophthalmic clinics to measure day and night vision.
