You know what... I lied to you, sorry. I've tried both aricept and Namenda and neither of those helped me... the one I just started is Strattera. The aricept and namenda are both normally alzheimers medications and unfortunately neither of those helped, so now I'm going the route of trying the adult ADD medication to see if that helps. I'll let you know how the strattera goes. The effects are different for everyone though, so just because they didn't work for me doesn't mean it wouldn't work for you. My neuro gave me a month on each one and if I didn't see an improvement he switched it. Problem is, it won't repair the holes in my brain, so I'm not holding my breath about my memory... see I even told you the wrong medication I just started... and my husband says I'd lose my head if it wasn't attached. Oh well, life goes on weather I like it or not., lol.
