This is from a new study, although I know we've had postings on this before.

Previous research suggested that statins can protect against neurodegenerative diseases, like Parkinson's, but a new analysis of a large US patient database shows otherwise.

.....people using statins tend to have a higher risk of developing the disease than controls. The association of statins with a diagnosis of Parkinson's disease was also significant.

Researchers believe that the results could stem from the fact that high cholesterol is thought to have a protective effect on the risk for Parkinson's disease, and therefore lowering cholesterol with statins may be harmful for some people.

Statin use may lead to increased risk for Parkinsons disease, new research finds
