Hey Chris, read this. It may help you put all of this into perspective...
"A seizure is a drastic change in the normal physiological neural state which results from abnormal electrical activity in the brain (sometimes called a bio-electrical storm). Given the right set of circumstances, anyone can experience a seizure. The occurrence of a seizure as a result of some acute precipitating physiological circumstance does not mean that it will ever happen again after the precipitating cause has been resolved...and does not mean the individual has epilepsy."
This is exactly why things like dehydration, hypothermia, flu, alcohol intoxication, severe stress, etc. can cause a seizure...that doesn't ever happen again.
