Low LDL Cholesterol Levels Linked to Parkinson's Disease CLICK FOR MORE: "Doctors consider low LDL cholesterol levels one of the gold standards for good health as this type of 'bad' cholesterol increases the risk of cardiovascular disease, the nation's leading killer. New data from a small, retrospective study show a link between low LDL levels and Parkinson's disease.

The study, which will be published in the January edition of Movement Disorders, compared 124 people with Parkinson's with their spouses who didn't have the disease. It found that people with low LDL levels (lower than 114 mg/dL) had a 3.5-fold higher occurrence of the disease than those with higher LDL levels (more than 138 mg/dL). For comparison, the average LDL level of Americans 20 and above is 123 mg/dL.

'However, people absolutely should not change their diet or try to change their cholesterol levels,' says study author Xuemei Huang, a University of North Carolina School of Medicine neurologist who specializes in Parkinson's. She strongly emphasizes that her results, though intriguing, need to be confirmed by additional prospective studies..."
