Topamax and memory

Hi all,

Hope someone can help, about 4 years ago I was diagnosed with TLE after suffering for around 18yrs without knowing what was wrong with me.
After my youngest daughter was born in May 2010, my neurologist put me onto Topamax and welbutrin in conjunction with my GP after my post natal depression. I have had quite a few memory recall issues, but nothing I would really find reason to complain about considering that having these stupid seizures for so many years have left huge gaps in my long term memory.
What I would like to know is, with my memory recall issues, could I take something like Ritalin to help with my concentration levels? I’m just finding that, my brain is generally "slower" and with a business that I run from home (a mother and child stimulation group) which I need to be at 100%

Thanks
