I have temporal lobe epilepsy and for as long as I can remember, at times during the day (when I am tired, stressed, etc...) I get a word stuck in my head that I repeat (in my mind)forwards then backwards. This goes on - back and forth - for awhile. Sometimes I get focused on adding numbers up and repeating the math problem forwards and backwards. I don't know if this is just a weird nervous habit or a symptom of my seizures. Has anyone else out there ever experienced this?
