ECT has a 50% success rate. That's very good.Considering the results of the medications you have already tried. The topamax is a mood stabilizer but it is also a medication to avoid migraine headaches,usualy taken daily. Memory loss is normal side effect of ECT, but it's effects seem to influence only short-term memory. You have a lot to weigh and consider. I hope your decision relieves you of your pain.

Good Wishes, Always,
