Head Injury, Frontal Lobe Seizure, Taken Depakote, Keppra, Lamictal, Gabapentin, Lorazepam

Question: In 1996, I hit the front of my head on a fireplace real hard and it knocked me to the ground. I held my head for quite a while until the pain subsided. I then had a headache for three hours which went away and I was alright ever since utill XXXXXXX of 2009 when upon arising from sleep and walking across the kitchen floor to make a pot of coffee, something horrible came over me in my head and I though I was having a XXXXXXX stroke. It lasted for just a few seconds. I didn't pass our or jerk or anything. It then happened again in a couple of days so I decided to go to my doctor. He had me take an MRI if the brain and all he could find was narrowing down of the small blood vessels. He said that came with my age (which was 65 at the time) and the fact that I am a smoker. However, I still kept having these spells. So, I went back to my doctor and he had an EEG done still nothing. So he sent me to the neurologist and the neurologist had another 2 MRI done. One with contrast and one without. Still nothing. So I suggested he do another EEG and leave it on longer. So, I had it on for 48hrs. and from this EEG the neurologist determined that I am having left frontal lobe seizures. I have been on depakote, keppra, lamictal, gabapentin, lorazepam and none of these seem to help. Some of these medicines even made my spells worse..I do not pass out, or convulse, I usually on my own just tense up as I am not sure what to expect next. I am coherent and they last approx 10 to 20 seconds and subside. Sometimes I have four or five a day, and then maybe 2 or 3 a day and then sometimes, just one a day and they are never everyday. There are times I will go for almost a week with out one. I am not doing anything different to bring them on. Can you tell my what your opinion is and what I can do to prevent them? I also had balbar polio when I was 7 yrs. old, I also had surgery on my celiac artery in 1972, as I was born with it inside my diaphram. Can you give me any explanation for these spells and their causes and what to do to treat them. Thank you, XXXXXXX Graber
