Studies show that most people with Parkinson’s disease have an average life expectancy. So, if you or your loved one has Parkinson’s, you may expect to live as long as, or almost as long as, people without the disease.
Modern treatments and medications that help manage symptoms and reduce their severity also aid in the prevention of potentially fatal Parkinson’s complications.

Nonetheless, one study proposed that a person’s life expectancy may be affected by their type of Parkinson’s disease. In particular, people with idiopathic Parkinson’s disease seem to have a mostly normal life expectancy.
In addition, the age of onset can affect the lifespan of someone with Parkinson’s. For example, one study showed that Parkinson’s could reduce life expectancy if the person is diagnosed before 70.
