What is Parkinson’s Disease?
Parkinson’s Disease is a brain disorder that occurs when certain nerve cells in the part of the brain that controls muscles and movement are damaged or die. Normally, these cells produce a chemical (dopamine) that lets the body's muscles move smoothly. According to the National Parkinson Foundation (NPF), the symptoms of Parkinson’s disease appear when about 80 percent of these cells are damaged.
Parkinson's Symptoms
- Tremors or shaking
- Slow movements
- Stiffness
- Balance problems
- Loss of facial expressions
- Shuffling walking
- Speech changes
- Nervousness
- Depression
Although Parkinson’s disease usually appears after the age of 65, 15 percent of people with the disease are younger than 50. It affects men and women at almost the same rate. While there is no test that can diagnose the disease, tests are done to rule out other conditions with similar symptoms.
Treating Parkinson’s Disease
Medications can be used to ease or control the symptoms of Parkinson’s disease. Since most of the symptoms of the disease are caused by a lack of dopamine in the body, the most commonly used medications replace or imitate dopamine. Doctors may suggest:
- Physical, occupational or speech therapy
- Surgery, which can ease the symptoms of Parkinson disease, but is not a cure
Preventing Parkinson’s Disease
There are no known ways to prevent Parkinson’s disease.
