Nationally ranked care. Another way our love for kids just keeps on growing.

A patient prepares for her EEG.


Pediatric EEG and Neurophysiology Department at SSM Cardinal Glennon Children's Medical Center

Electroencephalography (EEG) is the recording of electrical signals in the brain. This process can detect abnormal activity in your child's brain that may result in seizures. 

The EEG Department at SSM Cardinal Glennon does not administer treatment to patients, but works closely with other hospital departments like Neurology and referring pediatricians in the community.

Signs and symptoms

Signs that your child may have irregular brain activity:

      Dizzy spells

      Blurred vision

      Frequent headaches



      Weakness on one side of the body

      Staring spells

You should first discuss these signs and symptoms with your primary care physician to identify if an EEG is necessary.

What to expect during your child’s EEG

Patients who arrive on time are generally seen within ten minutes of arrival.

  1. Your child’s head will be measured and marked to make sure the electrodes are placed over the key points of his/her brain for accurate results.
  2. These points will be cleaned off so that dead skin cells and body oils do not block the brain’s electrical signals.
  3. A cream will be applied to the electrodes which are held in place by medical glue, gauze and/or tape.
  4. Your child will be asked to relax, close his or her eyes, and try to take a nap.
  5. While your child sleeps, a technologist will monitor his or her level of consciousness, body position, muscle twitches, etc.
  6. After a short nap, your child will be awakened and two activation procedures may be attempted:
    - Hyperventilation: asking your child (if old enough) to breath quickly and deeply.
    - Watching a strobe light.
  7. Finally, the electrodes will be disconnected and your child’s scalp will be cleaned prior to leaving the department.

Each patient is recorded on video which is time-locked and recorded directly to the EEG. This means that if your child blinks on the video, the same movement can be seen on the EEG at the same time.

In most cases, parents are welcome to stay with their child during testing.

Other available tests include:

  • Overnight EEGs
  • EMGs (Electromyographies)
  • Nerve conduction tests
