I should know this answer but i want conformation one way or another.can stress trigger a epileptic seizure?

Yes: Physical and emotional stress can indeed be seizure triggers in some epileptics. This is part of the reason staying healthy and getting plenty of rest is so important. Here's a web page on seizure triggers. http://www.epilepsyfoundation.org/aboutepilepsy/diagnosis/seizureprovokingtriggers.cfm.

If you have epilepsy: Stress won't give you epilepsy. But if you have epilepsy, stress does often make it easier to have a seizure. In fact, I have yet to find a medical problem that gets better with stress!
