My Mother has been on lamictal for approx 21/2 mths weaned off of dilantin. Her short term memory... has gotten terrible, from minute to minute she can't follow you. Very disturbing. She is 78 and had been on dilantin and phenobarbital for about 55yrs. Please someone tell me if they have or someone they know have the same symptom. Thanks so much! Her memory was failing a llittle before this med was added, but now it is to the point that I think I need to start staying with her.
