What are the 15 Symptoms Indicating Parkinson's Disease?

12. Sialorrhea

Excessive saliva and drooling is another symptom of Parkinson's. Some physicians see this as a motor symptom, but others say it is more likely a result of swallowing issues, such as dysphagia, or other automatic actions of the body. Individuals with Parkinson's have a reduction in these automatic actions. They produce a normal amount of saliva, but they have difficulty swallowing and so the drool pools in their mouth. The more severe the drooling is, the more difficult it is to swallow.
