this is fascinating.   so much for posting it.
one step closer to non-invasive assessment of ICP, or at least an approximation of it.
I do suspect that this issue of neck anatomy in IIH may be more important than we realize.
I went into remission from mandibular advancement: changing the relationship of my jaw and neck anatomy.  13 years ago, I believe I went into remission from a thyroidectomy.  at the time we didn't know I had IIH, but I know in retrospect that I did at that time, and that the thyroidectomy eradicated my symptoms.  it seems to me to all be related to compression of the jugular veins.  this article points out just how fragile our necks are, how easily flow can be disrupted.  I know people who are very careful with neck position and find it makes a difference.  I have noticed a difference if I sleep with a cervical collar.  probably we should all be sleeping upright.  I just can't do it.....
