Dorothy, your post was like reading my own biography. My daughter was diagnosed w/ epilepsy 4 days before turning 18, after five years of misdiagnosis by multiple docs.Long story short some medications can have effects on memory. When my daughter was on a certain dose of depakote and lamictal- she started forgetting things alot, she would do her homework and then forget she had done it. She would eat dinner and 2 hours later as what we were having for dinner.
What I am trying to say is it could be how she is metabolizing her meds and not the epilepsy itself. Be firm with your neuro and demand a blood test. My daughter is in the college of her dreams and although her form of epilepsy is lifelong and I worry about 18 hours a day - for the first time in a year I can sleep now, and she is doing well. You can drop me a note via this site anytime you want. Hang in there and God bless
