I have not heard of Lamictal causing memory isssues. I know Topamax (dopamax) does. I took it for awhile for migraine prevention and ndoc warned me that may cause memory issues. It wasn't an issue - my head was completely empty - I couldn't find the sentence, much less the word. Of course I started a new job around the same time and the person training me wondered what kind of idiot was replacing her. lol
