New MRI research shows that the changes in the brain blood flow which have been associated with vein abnormalities are not specific to multiple sclerosis (MS).  Before this research was done they have speculated that these changed in blood flow did contribute to the severity of the disease, but they have recently learned that it does not. 

 MS is a central nervous system disease where the immune system attacks the nerves.  Although there are many different types of the disease and the symptoms and severity varies, MS is a serious and deadly disease.  They have speculated that MS and chronic cerebrospinal venous insufficiency (CCSVI) are similar, and that MS may be able to be treated with endovascular procedures like stent placement. 

 However, from this study they have learned that the brain blood flow is not what makes the disease more severe and they are still unclear on the role of the abnormal blood flow.  

 "This study clearly demonstrates the important role of MRI in defining and understanding the causes of MS," Dr. Marziali said. "I believe that, in the future, it will be necessary to use powerful and advanced diagnostic tools to obtain a better understanding of this and other diseases still under study."
