How fast does Parkinson's disease progress?

In brief: Slowly

Once the diagnosis is made, the initial problems can be handled with Dopamine agonists and seem stable for 1-2 yrs, but then the progression requires l-dopa, which may help nicely for about 6-8 yrs, during which time additional meds may be added.
By 10-12 yrs the medications are sharply losing efficacy, and the next step may require use of a deep brain stimulator device.

The progressive nature of the disease is variable among patients. Everyone is different. Some report a rapid decline during the first year followed by a slow steady decline for the next 10-15 years.
