What's an EEG (Electroencephalogram)?
en español: EEG (Electroencefalograma)
Doctors use electroencephalograms to figure out what's going on in your brain. A special machine measures your brain waves to create an EEG. No matter what you're doing (even sleeping), your brain gives off electric waves. An electroencephalogram machine measures these electric waves and shows where and how big they are. Some kids have a lot of extra electricity flowing inside their brain, which can cause things called seizures. An EEG does not hurt and it can help doctors decide how to treat someone.
