Do you have the Parkinson's runny nose syndrome? Could it be a pre-motor symptom?
Hubert Fernandez and Joe Friedman have both written about the “running nose syndrome” and Parkinson’s disease. Here is the bottomline from their research.
In the first study Dr. Fernandez compared the prevalence of idiopathic rhinorrhea (runny nose) in PD patients versus controls.
There was a cohort of 61 PD patients and 51 age-matched controls who completed a survey about rhinorrhea and who also underwent the University of Pennsylvania Smell Identification Test (UPSIT).
6% of controls versus 24% of PD patients had rhinorrhea.
2% of controls versus 15% of PD patients had severe rhinorrhea.
Dr. Fernandez and colleagues concluded that rhinorrhea was more prevalent in PD patients compared to controls and it did not impact performance on the smell test.

Two more studies were conducted by Joe Friedman and colleagues at Brown University.
They performed a cross-sectional study and a study of consecutive de novo newly diagnosed patients.
They found that rhinorrhea affected about half of Parkinson’s disease patients in Rhode Island.
It seemed to be an early feature, being present at the time of presentation.
It was significantly more common than in controls and was associated with self-perceived reduced olfaction.
The authors felt rhinorrhea could be a premotor symptom.

The bottomline is that the “runny nose syndrome” is more common in Parkinson’s disease.
