answer:Are they going to do a 24 hour EEG? You have to ask how long it will be. Also, I assume you can be with him during it. Possibly they are going to just do a quick one and see what they find. If they see nothing they might want to do a longer one. No needles, unless they are going to draw blood for something else. If it were me and my child, and if it is for hours, I would try not to let them do anything else besides the EEG on that day, especially nothing like drawing blood. The EEG is just electrodes on your head, similar to when you get an EKG for your heart. It’s a bunch of electrodes in a small space, your head, and It feels a little heavy on your head, mainly because you feel tethered, and it makes it difficult for some people to sleep if they need to wear it while sleeping. His hair will get all yucked up with what they use to attach the electrodes. It washes out though, it just all is annoying feeling, nothing hurts. If he doesn’t like things on his head, like hats, he might not deal with it well. I think if you present it right he will tolerate it very well. Especially if it is a short duration one. I think they also have ones that are like hats for babies, but I am not sure the difference. Definitely ask the specific questions to your health care provider obviously, don’t just go by answers here. Have them describe exactly what to expect. One other thought, I don’t knowif they will try to help trigger an epilectic seizure during part of it. I’ve never heard that, but it would make sense. Maybe put on a strobe light that sort of thing. That is a total quess on my part, it just seemed logical. Do your doctors get paid by procedure? Like America and Canada? Since you feel strongly it is not some sort of seizure I was just wondering. Also, would you treat his epilepsy if he is having seizures with medicine? If not, why bother finding out.
