have you had a CAT scan or an ekg? those might be helpful.
At 12 yrs. old I had my 1st seizure, my parents thought I was doing drugs and had an overdose reaction.
Through out that same night I had 4 more grand mal seizures, (they watched me sleep), and thought maybe I was having a stroke. http://www.healthboards.com/ubb/confused.gif
They took me to the E.R., found out I was having seizures. I was in a car wreck with my mom and went through the front window, they thought the impact of the hit is what brought mine on, or it could have been my age with puberty sneeking up on me. As an adult I went to have brain surgery to have it removed, I had a 5% chance of coming out normal, because of were the mass was on my brain. I dint have it done.
As I got older, my test started showing nothing, no mass on my brain. My DR, has told me I now have a seizure disorder...meaning I am bringing most of my seizure on myself due to stress and anger. Because I had them as a child, I learned how to control my stress & anger by seizureing, as an adult I have to learn how to release my stress and anger other ways to not seizure. It is weird how powerful our mind is, and we dont realize it. Good luck with your situation and God bless.
