An electroencephalogram (EEG) is a safe and pain-free test that records the electrical activity of the brain. The information is recorded on a computer and interpreted by a paediatric neurologist (a doctor specialising in disorders of the brain).
Your child’s doctor may request an EEG to find out what’s going on in the brain if your child has abnormal movements, seizures or sleep problems.
An EEG is not harmful. There are no X-rays or injections and there is no risk of electric shock. The electrodes just record brain activity. Some children may fear that the machine can read their thoughts or dreams, it is important to reassure your child that this does not occur.
During setup, your child will not feel anything other than their scalp and hair being touched, and the procedure will not hurt at all. There are no side effects from an EEG.
The EEG procedure will be performed in accordance to standard paediatric guidelines as followed by the major paediatric Centres like The Royal Children’s Hospital Melbourne.
You are welcome to stay in the recording room during the EEG if you wish. Babies and young children can be held in their parents’ lap during the test. It is important to arrange for another adult to look after any other children while the recording is being done as they cannot stay in the room.
A video is recorded in case a seizure episode occurs. This gives the neurologist an accurate visual record along with the EEG recording. If no events are recorded, the video is deleted.
Sometimes doctors will request that an EEG is performed while a child is asleep.
Please do not let your child sleep on the way to your EEG appointment. Sedation (sleep medications) is not used to help your child get to sleep for an EEG.
An Ambulatory EEG is one where patients get the EEG electrodes placed on their heads by the technologist and after a few checks, they are sent home. The EEG is recorded at home, often overnight, to record sleep and any nocturnal events. There is no video with an ambulatory set up. The patient comes back to clinic the next day to get the electrodes removed.
A home video EEG monitoring (HVEM) is similar to an ambulatory EEG, but with additional video to record the typical events or seizures while at home. HVEM records for longer periods, typically over 2 or 3 nights at home. The EEG technologist will send you home with instructions for care and also a seizure diary to mark the events.
A routine EEG usually takes about an hour, but sometimes it may take longer, especially if a sleep recording is needed.
An ambulatory EEG is recorded at home over 24 hours.
A HVEM is recorded at home over 48 to 72 hours.
EEGs are very safe. The electrodes record activity – they don’t stimulate the nerves or send any electricity into the brain, so there is no risk of getting an electric shock. EEGs don’t involve X-rays or pain. If stimulated, an EEG can cause a seizure in a child who has a seizure disorder, but the experienced staff know what to do in these circumstances. Talk to your doctor about any risks associated with EEGs and any concerns you have.
The EEG technologist cannot tell you the results, and administration staff will not provide results over the telephone. You must make arrangements with your doctor to receive the results.
The average turn-around time for formal reports is:
In urgent situations, or if an abnormality is seen on the EEG, the reporting neurologist will contact the referring doctor as soon as the EEG is done to give a verbal report.
Out-of-pocket charges will apply as this is a private service.
