I was on Lamictal for quite a while and didn't notice a lot of memory problems associated with it, it could in fact be the seiszures that are affecting her attention span. I'm on Topamax now and have a severe memory deficit (albeit after right temporal lobectomy surgery like Sue). Topamax as my doctor has told me is nicknamed the "Skinny Stupid" drug. Because of what it does to your memory. So not only is my memory damaged from the surgery but is even more so from the drug. Does great for the migraines and I've finally found something to control my seizures, but I guess the price I pay is the fact that I have a terrible memory. Verbal is terrible and visual is not much better (watching a movie twice in one night to not recall it the next day at all). But I can function now, so that is the choice I make.
How is she otherwise?
