Could Parkinson’s Disease Raise Stroke Risk?
A large new analysis suggests there may some type of link between Parkinson’s disease and the risk for stroke.
However, the study can’t prove that one condition causes the other — or even which direction the link might travel, the researchers said.
For example, maybe Parkinson’s somehow raises a person’s odds for ischemic stroke — the type that’s caused by a clot and makes up the vast majority of strokes. Or, it could be that having a stroke weakens the brain, raising the risk that a patient will develop Parkinson’s.
Or, as one expert who reviewed the findings said, a separate, unknown factor might independently link the two conditions.
