A video EEG (electroencephalograph) records what you are doing or experiencing on video tape while an EEG test records your brainwaves. The purpose is to be able to see what is happening when you have a seizure or event and compare the picture to what the EEG records at the same time. Sounds that occur during the testing are also recorded - this can pick up if a person talks or makes sounds during an event. By doing this, doctors reading the EEG can tell if the seizure or event was related to the electrical activity in the brain. If so, we'd call this an epilepsy seizure.
