A video EEG (electroencephalograph) records what you are doing or experiencing on video tape while an EEG test records your brainwaves. It is completely painless and non invasive test and can be done on children and adults safely.
The purpose is to be able to see what is happening when you have a seizure or event and compare it with the EEG records at the same time. 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 had call this an epilepsy seizure.
Video EEG is most helpful to determine if seizures with unusual features are actually epilepsy, to identify the type of seizures, and to pinpoint the region of the brain where seizures begin. Locating the region precisely is essential if epilepsy surgery is being considered.
Video EEG is also useful to differentiate various paroxysmal spell like pseudo seizures, parasomnias and other non-epileptic spells.
