There are no two persons with Parkinson’s disease that have exactly the same symptoms and course of the disease. There are some people who experience tremors more than others, or some that are more affected by inertia or stiffness. The response to medication and the possibility of side effects can also vary among patient. Even the responses to non-medication treatments (e.g. physiotherapy) may differ. Dealing with Parkinson’s disease, its symptoms and its treatments vary greatly from person to person.
