I've had memory problems as well.

More frustrating is that I've mostly lost the ability to do complicated equations and physics in my head. I can't do most of it at all any more. I do find my command of the language has improved slightly and I write a lot better.

The doctor told me a lot of the memory problems are related to the drugs and would probably clear up if I can get off of them. I use 120 mg of ghinko biloba daily because it helps with pain but this is supposed to help memory. I don't think it does for me.

Long term memory is worst for me but the 10 sec memory is affected too.

There have been numerous changes mentally.
