A study has found that fat soluble statins, medications used to reduce levels of cholesterol in the blood may speed up the onset of symptoms of Parkinson's in people, susceptible to the disease. Parkinson's disease is a disorder of central nervous system that affect movement. Previous research has suggested that statins may protect against Parkinson's. Research has been inconsistent, however, with various study showing a lower risk, or no difference or higher risk of Parkinson's in statins users. The new study says statins use were associated with higher, not lowe, Parkinson's risk, and the association was more noticeable for lipophilic statins, an observation inconsistent with the current hypothesis that these statins protect nerve cells.There are two types of stains. Water soluble statins can not get in to the brain, while fat soluble stains called lipophilic can. The team analysed data for more than 50 million people under 65. They found that prior stain use was associated with higher risk of Parkinson's and was more noticeable during the start of the medication use. The research is published in the Journal of Movement disorder.
