Hypersalivation or excessive secretion of saliva is a symptom which can be very distressing for a person, and more so in a patient suffering from Parkinson’s disease, who already has to cope with so many other problems caused by the disease. Hypersalivation, leading to drooling, can be a manifestation of the condition or it can be due to drug therapy in Parkinson’s disease. There are various other causes for excessive salivation which may be superimposed in a person already suffering from Parkinson’s disease.
Parkinson’s disease is a degenerative disease of the brain where there is decreased production of the chemical transmitter known as dopamine. The classical symptoms of Parkinson’s disease are tremor, rigidity, bradykinesia (slowing of movement) and loss of postural reflexes. Drugs are the mainstay of treatment in Parkinson’s disease and while there is no definite cure, drug therapy is used to help control the symptoms.
Classifying different stages of Parkinson’s disease is essential for monitoring the progression of the condition as well as identifying any headway made with certain treatment options. There are generally five stages of Parkinson’s disease and due to the slow progression of Parkinson’s, it may be difficult at times to clearly categorize individual cases into specific stages. The intensity of symptoms of Parkinson’s disease may vary, sometimes even on a daily basis, and certain cases may even skip some of the early stages of Parkinson’s disease. Stage 1 of Parkinson’s Disease (Mild) Symptoms are mild and may only affect one side. Daily functioning is not impaired although tremors create difficulty. Slightly evident changes in balance, posture, movement and facial expression.
