MAJOR loss of short-term memory and inability to concentrate. ...

MAJOR loss of short-term memory and inability to concentrate. I have been on Lamictal (for bipolar tendencies) for 3 or 4 years now. Overall it has been really great for me -- really calmed me and leveled me out like no other medication has. Except that it has made me embarrassingly dumb. I have a graduate degree in electrical engineering, which is pretty worthless at this point because I cannot add two simple numbers in my head. My grammar and spelling skills have taken a nosedive. I took a grammar refresher class to try to boost it again, but I couldn't concentrate and can't remember what I learned. And even worse, sometimes I can't remember basic things like which way to flip the turn signal lever to signal left or right when I am driving. I went up to 350 mg and it worked great (for the bipolar), but I could barely function at my job. So I've lowered it slowly to 150. My brain works a bit better, but still not well. Today in a meeting I was explaining something important and realized a couple minutes later that I was totally wrong -- I'd remembered incorrectly. So I had to interject later and explain that I'd been wrong. Things like this are very embarrassing and ruin my credibility at work. But as I said the Lamictal has been amazing in other aspects. Ultimately I don't know if trading my brain for that is worth it, but for now it is because no other medication has worked. I worry though that even if I stop it in the future, my brain may not be able to recover, from lack of use. Thank you all for your information. I am relieved to know I am not alone.
