An electroencephalogram (EEG) lets a doctor see the electrical activity of your child's brain.
Your child will have small pads or patches attached to different places on his or her head. These are called electrodes. Wires connect the electrodes to a computer.
The computer records the activity of the brain. This looks like wavy lines on the computer screen or on paper.
The test is often used to diagnose epilepsy. It helps a doctor know what types of seizures a child is having.
An EEG can also check brain activity in people with sleep disorders.
It can also help a doctor know why a person passed out (lost consciousness).
The test will take about 1 to 2 hours.
Watch closely for changes in your child's health, and be sure to contact your doctor or nurse advice line if:
Follow-up care is a key part of your child's treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if your child is having problems. It's also a good idea to keep a list of the medicines your child takes. Ask your doctor when you can expect to have your child's test results.
