Could IDIOPATHIC INTRACRANIAL HYPERTENSION be a cause of unexplained seizures?

Wouldn't IIH show up in the typical tests that are run to find a cause of seizures? Some background: Last Oct. I started getting grand mal seizures. During my stay in the hospital, I had CAT scans, EEG, and lots af bloodwork. Everything came out normal; no cause for the seizure could be found. I was sent home without medication as they thought it was just a one time occurence. Well 2 months later, I had another seizure and had all those tests run again, adding an MRI and ultrasound of the veins of my neck. Still normal; no cause to be found, but this time I went home with Dilantin (anti-seizure med), which I'm still taking (probably for life). On the med. I had no more occurence of seizure, so life got back to normal. I then started researching WLS and came across Idiopathc Intracranial Hypertention (high pressure in the fluid around the brain) as a co-morbidity factor of morbid obesity. So, I'm wondering if this IIH has anything to do with seizures, maybe it being a cause? Or would this have shown up on all that testing I had done? Btw, I did have my surgery (open distal RNY) about a month ago, on 5/21/01. So far, so good as far as seizures are concerned. I had to switch from the pill form Dilantin (couldn't get them down) to the liquid form (YUK! GROSS! I now call it YUK-lantin instead of Dilantin). Though I will have to have my Dilantin levels closely monitored and dose adjusted as needed, as my weight goes down.
