I continue to be disappointed with the medical fields notion that obesity has caused IIH.  If this were true then it would not be idiopathic.  Granted the article did not directly say obesity caused the IH it was implied in at least 3 times.  It is easy to blame the patient for being obese and in my opinion is often used as a way to shirk responsibility if a patient dosent respond to treatment.   It is akin to saying "Ms Doe dosent want to get well enough to lose weight so it is her fault".  I was thin when the daily headache started and gained a massive amount of weight through the years.  I want every physician to sit down a minuet and think about how hard it is to be active when it feels like you have a marching band in your head.  
  
   I am also confused by the last statement about "Until now, we had little evidence of why surgical shunting or IVUS stenting worked,".  It is possible I am misreading the statement or not comprehending what the intent of the statement is.  It was my understand it was a proven fact that shunting was understood to work from the removal of the excess spinal fluid.  

I am glad to see some success stories of the stenting here, alas the majority of people with IIH that I  know do not qualify for the stenting process.  So we return to square one.
