Key points

  • An EEG measures electrical activity in your child's brain to help your child's doctors see more clearly where seizures start.
  • During the test, your child will lie still on a bed and do different activities while electrodes are attached to their scalp to record the activity in the brain.
  • If your child needs to take a sedative before the test, follow any eating and drinking instructions from your child's team.
  • You will be able to discuss the EEG results with your child's doctor about four to six weeks after the test.
