My memory loss has only been since I had my 1st epileptic seizure before then I had a good memory a friend even tested me on it by telling me some numbers to remember and only asked me for them late at night and yes I remembered them! Now if he did the same thing I would forget within 5 minutes! I also get awful migraines that can last from half a day to 2 full days solid. I had a 21/2 day migraine from Friday afternoon to Sunday night just gone.
