ESTROGEN AND THE RISK OF PARKINSON'S DISEASE

Movement Disorders [2009] May 7 [ahead of print] (Simon KC, Chen H, Gao X, Schwarzschild MA, Ascherio A.) Complete abstract 

Researchers have assessed whether estrogen and reproductive factors are associated with the risk of Parkinson's Disease. Estrogen has numerous effects on dopamine, and Parkinson's Disease is more common in men than women. So it had previously been theorised that estrogen could have a therapeutic effect on Parkinson's Disease.

Use of postmenopausal hormones did reduce the lessening effect of smoking and caffeine intake on Parkinson's Disease. Also, women using progestin-only hormones were found to have an increased risk of Parkinson's Disease, but this result was based on only a small number of cases, and so might not be statistically significant.  For more current news go to Parkinson's Disease News.
