If you are worried about this you can talk to the technician. This involves looking at a light which will flash at different speeds. This is called photosensitive epilepsy and it affects around 3% of people with epilepsy.Īn EEG will usually include testing for photosensitive epilepsy. Some people with epilepsy have seizures that are started, or ‘triggered’, by flashing lights. The test may include deep breathing to see if epileptiform activity can be provoked and recorded. 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.Įpileptiform activity can sometimes be provoked (brought on) by deep breathing. 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. The recording shows how the brain is working.Īn EEG gives information about the electrical activity of the brain during the time the test is happening. These signals are picked up by electrodes attached to the head and are recorded on a computer.
At the same time, the digital video recording of your child will be made – this is helpful for the doctor to observe any symptoms, changes in behaviour or movements that could be associated with seizure activity on the recording.ĭuring the test, the CP may ask your child to lie or sit quietly if possible or continue to play. Your child will not feel anything while the EEG is being recorded. The CP will record your child’s brainwaves on to the computer and monitor them on a screen – they look like wiggly lines. The electrodes are attached by wires to a ‘headbox’ and then to the recording machine.

While all the electrodes are being applied, your child can sit on a chair, the bed or your lap, and can play with toys – we have many toys in the department but feel free to bring your child’s own favourite book, toy or comforter. This should take around 20 to 30 minutes. This does not hurt but some children do not like it. Sometimes, additional electrodes may be applied to other areas in order to get more information.Īs each electrode is attached, the CP will clean the area of the scalp with a cotton bud and some cream. Extra electrodes will also be applied on the shoulders to record your child’s heart rate and muscle activity. Sometimes, they will measure the head beforehand and mark the points with a soft pencil before attaching the electrodes. The CP will attach a number of small silver discs (electrodes) to certain points on your child’s head using a soft paste.
