3. Parkinson's disease mainly affects the nervous system in the human body.
4. The exact cause of Parkinson's disease is unknown at the present time. However, research has pointed to many different causes that may all play a role in the development of the disease. One factor is genetics. In a recent study it was shown that people who have a first degree relative with Parkinson's disease, such as a parent, sibling or child, are at three times greater risk of developing the disease themselves. Another factor that comes into play could be the environment. Exposure to certain pesticides or chemicals can lead to Parkinson's. Also, studies have shown that taking certain medicines, such as Haldol or Thorazine, can increase one's risks of developing Parkinson's disease. Exposure to certain toxins can also be a cause for Parkinson's disease. In females, a decrease in estrogen levels, as a result of a hysterectomy or other causes, can be a cause. Also, a decrease in folate levels in the body can contribute to the development of Parkinson's disease.
5. There is no cure yet for Parkinson's disease. However, there are many different forms of treatment to help alleviate the symptoms. Many doctors will first want to try a lifestyle change such as exercise, eating healthy, etc. Also, many doctors will recommend patients going to physical therapy. A physical therapist will work with the patient on improving muscle strength, which will help the patient feel more self-confident and able. Therapy can also improve one's way of walking and equilibrium. If therapy is not working for the patient, a doctor may prescribe medications for their patient. The most popular medication for the treatment of Parkinson's is Levadopa. It is used to help manage problems with walking, movement and tremors by enhancing the brain's supply of dopamine. Levadopa is a chemical located in plants and animals that can be transformed into dopamine by nerve cells in the brain.
