I've only had this patient for around two years. This is the first time she mentioned HAES to me so I get the feeling she may have read the blog you described. Unfortunately, pseudotumor cerebri, known otherwise as idiopathic intracranial hypertension, affects thousands of people, predominantly women that are obese and of childbearing age. Basically it's a disease of fat women, and the fatter they are, the more likely they are to have it. Looking at the support groups on Facebook, they're chock full of hams in denial about their weight making them blind. Some even think the research is wrong, and there's some unknown pathogen that is both increasing their cerebrospinal fluid pressure and making them fat. It's breathtaking how dumb they are.
