An electroencephalogram (EEG) measures the electrical signals of your child’s brain through small button electrodes that are placed on your child’s scalp. Experts in neurology have studied EEGs for many years and determined that it is generally a safe procedure, with no significant risks.
There are three types of EEGs:
- Traditional EEG: Takes place in a clinic setting with about 25 electrodes.
- Dense Array EEG: Takes place in a clinic setting with about 250 electrodes.
- Ambulatory EEG: Takes place in a child’s normal daily setting. Electrodes are put on the scalp, and the patient is given a backpack that records the test results over several days.
Your child’s doctor will help decide which EEG is right for him. Learn more about each one:
What to expect during an EEG
During an EEG, special sensors are placed all over the head to measure the electrical signals the brain sends out. The test may take longer than an hour, but it should be painless.
