Sorry they haven't found the reason for the seizures yet. I assume they've also done a full check for MS.
You once listed your symptoms as (mental fog, memory loss, difficulty speaking, balance issues, tingling, itching, headaches, etc) as well as the seizures...
I had all those symptoms and ended up having some neuropsych testing done -- it showed that these things were really happening, and that I'd had a very dramatic and measurable drop/change in cognitive function. (Think 10+ drop in IQ points, for instance.)
Never had a spinal tap, never had much show up on more physical kinds of tests... proceeded to the next set(3) of lupus meds (1. plaquenil, 2. prednisone, 3. cellcept, imuran, Mtx, 4....) Imuran didn't do anything, but Cellcept after about
18 months put me in a kind of remission. My brain function isn't what it once was, but I don't feel so vegetable-like either, and most of the annoying symptoms are gone most of the time.
I guess I'm saying that treatment & improvement is available even if they never "find something".
