Here's some good information about epilepsy and anxiety.

unfortunately, the program on this forum likes to capitalize letters after periods (dots). Because of this, if you click on the link, it will bring up a page that says "page not found." to get there, you'll have to copy and paste it but then change the capital letters to lower case. It's a good page.
If i'm not mistaken, anxiety is not uncommon in temporal lobe epilepsy (especially if the hippocampus and/or amygdala are involved-- present in both the right and left temporal lobes). I believe that the amygdala is the area of the brain that processes emotions where the hippocampus is the area that stores short-term memory. (both are closely related).
