not a doctor, but you could try a 24 hour eeg. I had the same problem. I take trileptal if you would like to look into that, but that is just my opinion again I am no doctor. Trileptal has minimal side effects. Her doctor will probably know what it is. If the seizures are occuring at night they could be nocturnal seizures.
omega 3's could help with her memory.
It is common for people who have seizures to never show why in an MRI or EEG. Almost 50% of tests come back competely normal.
In my unprofessional opinion, I would assume her seizures are due to her hormonal imbalance. Especially since there is nothing obvious in any of her brain scans.
Could she try more Lamictal to keep it under control?
Her hormone levels and sleep problems together make me think possible mineral deficiencies. Can she ask her Dr about calcium/magnesium supplements? The combo is helpful for insomnia, seizures and hormonal problems. Many women especially sleep better at night when they take magnesium and calcium supplements - especially women going through menopause. I wonder if she may be deficient in any minerals.
Although more testing sounds like the answer...sometimes it isnt...all it is --is expensive. When I was 20 I started having seizures. They did MRI, CatScans, EEG, EKG, Sleep study, Spinal Tap, bloodwork, to say I am "normal", (other than my brain does not get deep sleep--so I have been on Ambien CR). We started with Tegretol--then when I decided to get pregnant at 24, they switched me to Trileptal. I went 3 years with no seizures, so they discontinued my medicine. Six weeks later I had a seizure. So even now, I have Epilepsy--but no reason WHY. This year I was changed to Keppra (because Trileptal started to decrease my sodium level). ***But one thing I wanted to mention....it can be frustrating, but you cant let her stop trying to accomplish her goals. My dad had to drive me to college for 6 months after I had a seizure (because I had to stop driving)--but I continued, and finished my Undergraduate Degree in the top 10%. I cant say it was easy (after having a seizure, and not being able to remember what happend the last few days--it did take more studying) But I finished school, had a healthy baby, and still have epilepsy. =) Mel
Have you or her spoken to the dr regarding her hormonal imbalance? this does greatly contribute to the seizures. Try to keep a record of them and see if they are more active during the 2 weeks prior to her cycle. Then you can take this to her GYN, and get some hormones. I think this would help solve the problem, as opposed to just "masking it" as the anti seizure medications are doing.
how is your daughter feeling? I hope she is better.
