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.
Parkinson's disease is a progressive, degenerative disease. This means that symptoms continue to get worse and new symptoms are seen.
Parkinson's disease is not contagious and poses no risk to others.
