Video is routinely recorded whilst we take these graphs as it can be very helpful in the
analysing process, especially as young children can find it difficult to sit or lay quietly for
any length of time – thus causing a great deal of artefact in the record.
It may also be possible to capture one of your child’s episodes on camera, therefore making it easier for the consultant to interpret the results.
To record your child’s brain waves we will need to measure his or her head using a
Lots of little, “cameras” the size of a pea will be placed onto the head and held in place with a butter-like paste. It is essential your child can remain relatively still – as these “cameras,” will easily slip and slide off!
We have facilities to entertain children who may need distracting such as a children’s
room, toys, and videos to watch, although these are not always necessary.
The more relaxed and settled your child is, the better the quality of recording will be
achieved. If you feel your child may not be able to tolerate the test feel free to bring
along their favourite teddy/toy/video and any appropriate items you feel necessary,
for instance – a drink, nappies, and pacifiers where required.
A TV/video may not always be available or necessary to get the test done. The test, from entering the room to leaving the department, including taking a brief history and setting your child up – should take approximately one hour.
A period of eye closure and deep breathing will be obtained. (We may need your help in obtaining these!)
Near the end of the test a flashing light, similar to a disco light will be shown to your child – these are very important parts of the test, which help maximise information.
There can be minimal risks associated with these procedures but these will be explained before and during the test by the recording physiologist.
Our aim is to achieve a good quality recording. If you or your child becomes uncomfortable or too distressed we will abandon the procedure and consider
alternative arrangements with yourself and your child’s referring consultant.
Please note that it is very rare a child will not be able to tolerate our test but in some
instances the test has to be abandoned if the child becomes too distressed or upset as
this can affect the quality of the recording. Sedation may need to be considered in these
Our children’s room is only very small – therefore the fewer adults needed to accompany your child into the recording room, the better.
Results are analysed and a report will be sent to your child’s consultant who will give
you the results. Results are not available on the day of the test.
