MichelleR, a member of our forum, asks about Lamictal and memory loss. She shares, "I take Lamictal currently at 125 mg. I don't take any other psych meds besides my Lamictal. My big problem is my memory. My short term memory sucks. I can't remember anything. It's in one ear out the other. But, I don't know if it's the meds or just my racing thoughts."
Some resources list "concentration problems" as a rare side effect of Lamictal, generic name Lamotrigine, so it is possible that your memory loss issues could be caused by the medication. This is most certainly something you should discuss with your doctor.
