This is important information when deciding whether surgery is an option or which part of the brain future investigations should be focused. It also shows how a seizure develops and spreads. The test may include deep breathing to see if epileptiform activity can be provoked and recorded.īy looking at which electrodes are stimulated during a seizure can help workout which area of the brain the seizures are coming from. Epileptiform activity can sometimes be provoked (brought on) by deep breathing. Some people can have epileptiform brain activity even when they do not appear to be having a seizure, so an EEG can be particularly useful for them. This change, known as epileptiform brain activity, can sometimes be seen on an EEG recording. When someone has an epileptic seizure their brain activity changes. What does an EEG show?Īn EEG gives information about the electrical activity of the brain during the time the test is happening. The recording shows how the brain is working. These signals are picked up by electrodes attached to the head and are recorded on paper or on a computer. An Electroencephalogram (EEG) records the electrical activity of the brain by picking up the electrical signals from the brain cells.
