There will be three or four small stickers on your child's head, connected to leads going into a computer. Sounds will be presented through an earphone to each ear separately while a computer analyzes the changes in the brain wave pattern in response to sounds.
Your child should be sleeping for the duration of the test. Young children under the age of six months are not usually sedated, and the test is performed while the infant is naturally sleeping, following a feeding. Children over the age of six months are usually sedated with chloral hydrate.
The test is not painful or uncomfortable in any way, but it is necessary for your child to be asleep in order to obtain clear recordings during the test.
You will be in the room with your child during the test, and the results will be explained immediately afterward.
