What can be done to prevent the disease?
Because the cause is not known, there is no known way to prevent Parkinson's disease. Avoiding exposure to environmental toxins, such as pesticides, may be helpful. There is very preliminary information that hormone replacement therapy, or HRT, in women may help prevent Parkinson's disease. Women may want to discuss HRT with their healthcare providers.
What are the long-term effects of the disease?
Parkinson's disease is a progressive, degenerative disease. This means that symptoms continue to get worse and new symptoms are seen.
What are the risks to others?
Parkinson's disease is not contagious and poses no risk to others.
