What's the cause, do they have a clue; are you having more testing done?

"Some seizures may be the result of another medical problem, such as low blood sugar, infection, a head injury, accidental poisoning, or drug overdose. They also can be due to a brain tumor or other health problem affecting the brain. And anything that results in a sudden lack of oxygen or a reduction in blood flow to the brain can cause a seizure. In some cases, a seizure's cause is never discovered." http://kidshealth.org/parent/firstai...s/seizure.html
