Hi Jonasl -- I started having sz in 1990 (when I was 46 years old) caused by an oligodendroglioma II tumor in my left temporal lobe but the MRI was mis-read so I wad diagnosed with idiopathic epilepsy.
Finally, in 2005, the tumor was found and I underwent every available test. Surgery was done Feb., 2006 and I did not have another sz until May, 2006.
A second surgery was done and I haven't had a sz since then!
I'm with a great hospital - Barnes Jewish which is part of Washington U in St. Louis. I go back every year for a MRI check-up.
What I'm trying to say .... I hope you are with a great hospital - that;s the most important thing.
I'll keep you in my prayers.
