Official title
Determining the Microbiota Composition of the Middle Meatus in Parkinson's Disease
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The exact cause of PD remains unknown, but current theories suggest that it results from a combination of hereditary or genetic factors (i.e. family traits ) and exposure to unknown substances in the environment. The purpose of this study is to investigate whether toxins produced by bacteria that live within the nasal canal (nose) and the intestines of people with PD might have a role in causing the disease. The investigators in this study would like to look at the types of bacteria that live in the nasal canals and intestines of PD subjects and compare them with those of subjects who do not have PD.
