What is Parkinson’s Disease?

Parkinson’s disease is a progressive disorder of the nervous system that affects movement. The cause of Parkinson’s is a result from a deficiency in the brain of a chemical called dopamine.  Dopamine is one of many chemical messengers (called neurotransmitters) in the brain that allow nerve cells to communicate with each other. Without it, messages from the brain to the muscles are disrupted. The amount of dopamine in the brain is reduced in Parkinson’s disease because some of the nerve cells that produce it are destroyed.

It develops gradually, often starting with a barely noticeable tremor in just one hand. But while tremor may be the most well-known sign of Parkinson’s disease, the disorder also commonly causes a slowing or freezing of movement.

Friends and family may notice that your face shows little or no expression and your arms don’t swing when you walk. Speech often becomes soft and mumbling. Parkinson’s symptoms tend to worsen as the disease progresses.

While there is no cure for Parkinson’s disease, many different types of medicines can treat its symptoms. If you are searching for new Parkinson’s treatment options for this condition consider participating in a Parkinson’s clinical research study.
