I don't wear one but I probably should. I don't have a shunt but I have other issues besides the IIH that probably should be on a bracelet. I had to think about it for a day but I think you are right. you don't hear much about people passing out from their IIH, but it does happen sometimes. and some of us develop seizures. if you passed out because your shunt was malfunctioning or infected, then it would be important for the docs to know to investigate that if you were still unconscious. I don't think it's as critical as, say, someone with diabetes, but it's reasonable.
