I've just been upped to the 50mg dose of the topamax (for migraines), and I haven't yet experienced any memory loss or slowed thinking etc. I'm a student and I do purely academic subjects (ie maths, physics etc) so i'd notice any memory loss etc. Am I likely to develop any of these symptoms? This is the first thing that seems to be working and the only side effect I've had seems to be some weight loss.

Also what's the highest dose I'm likely to be on?
