Analyzing nearly 44,000 patients, scientists found that those who discontinued taking fat-soluble statins such as simvastatin (Zocor) or atorvastatin (Lipitor) were about 58 percent more likely to develop Parkinson's than those who kept taking the drugs.

Fat-soluble statins are believed to cross the blood-brain barrier, unlike water-soluble statins such as rosuvastatin (Crestor) and pravastatin (Pravachol). The drugs may decrease inflammation and even modify dopamine pathways in the brain, which are linked to Parkinson's, the study authors suggested.

Lipitor clearly didn't prevent PD for me..........
