I know nothing about seizures and meds but noticed when I was in college in my 40's that I would study one day only to have it disappear the next day for the exam. I learned that many short study periods helps to put the information into the long term memory bank, and I realized that I didn't concentrate well at all with my hectic lifestyle and stress levels. I have learned that the brain needs exercise to keep it working well, and the memory works about like the muscles: the less you use it the weaker it becomes. I managed to do reasonably well in my classes, but nothing like the easy memory I had in my youth and the photographic memory I had playing music. A symphony musician told me they practice many hours a day in their older years to keep up the level of memory and skill in order to perform. So I work two Sudoku puzzles a day and play a few songs on the piano, read two newspapers, and try hard to understand something I am reading which makes no sense at all. I find that people who think differently are interesting to me while I try to figure them out, even though I don't always agree with their views. I never was an athlete but I stretch my brain. And I just love figuring out algebra and teaching basic concepts to children. It makes me feel like a winner, even though I no longer need to know much about algebra in my live.
My daughter balances my checkbook for me. I am spoiled in that respect. You need to keep working at it. And you need to sleep well.

MCI is basically only short term memory loss. Sorry, we have no experience with seizures or medications for seizures. Bonnie
