when i first had my SPECT scan to diagnose my epilepsy, there was an inkling i had bipolar disorder as well. we never really looked into it. i have days and weeks when im very optimistic and feeling well, feeling like i can get a lot of things done, and sometimes irritable and angry in between, and then it will switch almost immediately to very depressed and suicidal. i am on topamax for my seizures which i know can also treat bipolar disorder, but it doesnt seem to be doing much. im also on seroquel and lexapro for depression and anxiety, but im still having symptoms of both.
