diagnosing epilepsy: why do some EEG's show normal and others not?

I am frustrated. Some of my EEG's show normal, while others have epileptiforms on them. Which should I accept for a diagnosis?

    Some seizures it depends on they are produced so to say. I have grand mal seizures and you can only see mine while they are happening. Flashing lights don't produce mine

    I forgot to ask… what form of seizures are you having? There are some medical problems who tend to act as though they are seizures. ADHD for example can cause a person to have petimal like symptoms. If you are not having seizures regularly or for extended lengths of time, honestly I would discuss all options that the episodes could be before putting your body through the effects of anti seizure medication…which can be dangerous and actually cause seizures, not to mention other health conditions…

    That can be very stressful… My husband and I both are the same way. His never showed any abnormal brain activity (which I would have to beg to differ…lol) and the EEGs I took at the neurologist's office came out normal, while after I got into the Epilepsy Foundation, they would show unidentifiable abnormalities…

    Gosh, thegizzard, I really wish I could help you on this. I can't imagine why the read on the two EEGs would be different, unless some time passed between the two procedures. I know what you mean, though, about being frustrated! ;-) Mara

    This isn't the first time it's happened to me, either! my neuro is thinking about doing yet another ambulatory one, which, while a pain, showed seizures the last time it was done, about two years ago. I think I should err on the cautious side and assume I do have epilepsy. I'd like to hear from a doc on this one, too, if there are any out there reading! My doc is treating me with AED's, so I'm guessing she thinks I have it, too. Very, confusing and frustrating, AuntieM234! Glad to hear from you!

    I understand what you are saying. My daughter was having seizures for about 1 year before they ever showed up on a EEG. and she had several EEGs during that year. During 2 of them she had a seizure during the EEG and it still showed nothing. That was 22 years ago, now it shows her brain in constant seizure activity. It is very frustrating!!
