Risk factors for
Parkinson's disease are hard to identify, because
the cause of the disease is unknown. Advancing age is the only known risk

close relative who also has the disease. But it does not appear that a family
history of typical Parkinson's disease significantly increases your risk for the disease. Having a family history of the disease is a more
significant risk factor in cases of early-onset Parkinson's disease, but this
form of the disease is not common.

disease. But this has not been proved.

disease, but in fact is not Parkinson's disease.
