Parkinson’s is a neurodegenerative disease. Movement is normally controlled by dopamine, a chemical that carries signals between the nerves in the brain. When cells that normally produce dopamine die, the symptoms of Parkinson’s appear.

Most common symptoms are tremors, slowness and stiffness, impaired balance and rigidity of the muscles. Other symptoms include fatigue, soft speech, problems with handwriting, stooped posture, constipation, and sleep disturbances.

A diagnosis of Parkinson’s can take time. A family doctor might notice it first. You may be referred to a neurologist – a specialist who deals with Parkinson’s. There are no xrays or tests to confirm Parkinson’s. So the neurologist will check your medical history, do a careful physical examination and certain tests, and rule out other conditions which may resemble Parkinson’s.

Currently there is no cure. You can live with Parkinson’s for years. The symptoms are treated with medication. Some people with Parkinson’s may benefit from surgery.
