PARKINSON'S DISEASE NEWS 10th May 2008 - New research RHINORRHEA IS INCREASED IN PARKINSON'S DISEASE Movement Disorders [2008] 23 (3) : 452-454 (Friedman JH, Amick MM) Complete abstract Rhinorrhea is excessive liquid produced from the nose. For more information go to Rhinorrhea. Researchers found that rhinorrhea is increased in people with Parkinson's Disease, but only a single publication supported this observation. So they performed two further studies to assess the prevalence of rhinorrhea in Parkinson's Disease. They also questioned subjects as to whether rhinorrhea might be associated with olfactory impairment, which is known to be common in Parkinson's Disease. They found that rhinorrhea affects about half of people with Parkinson's Disease, which is significantly more than in people that do not have Parkinson's Disease. It was found to be an early feature of Parkinson's Disease, being present at the time of presentation. It was also associated with a self-perceived reduction in the sense of smell, which raises the question of whether some olfactory impairment found in Parkinson's Disease could be confounded by rhinorrhea, and also whether rhinorrhea may be a premotor symptom. The association of rhinorrhea with Parkinson's Disease is not explained by the researchers. Rhinorrhea normally occurs as a symptom of the common cold and allergies. So it's odd that they coincide to such an extent.
