If I had a seizure, do I have epilepsy?
No, in fact, there are many more people who have a single seizure than people with epilepsy. A single seizure could be caused by drinking too much alcohol, for example, and then withdrawing. Sleep deprivation can cause a person to have a seizure. Some kind of a toxin may also cause a seizure. But as I mentioned earlier, one seizure is not epilepsy.
