Procedure - EEG

An electroencephalogram (EEG) is a test that measures electrical activity in the brain in order to diagnose epilepsy, seizures, confusion, and other brain conditions. At Ogden Clinic, our specialists use EEG tests to help patients across Utah understand the way their brain functions and how that contributes to their daily health. Some of the disorders an EEG test can help assess include:

  • Epilepsy
  • Brain tumors
  • Stroke
  • Sleep conditions
  • Dementia


Before having an EEG test, it is important to remember to wash your hair before the test and refrain from using any hair cream or styling products (these can affect the electrodes’ ability to stick to the head during the test). Also, refrain from drinking anything with caffeine the day of the test, as it can interfere with accurate test results.

How It Works

  1. Once you arrive at Ogden Clinic for your EEG test, a specialist will measure your head and mark places on the scalp where the electrodes will be attached. EEG tests are not painful, as the electrodes don’t transmit any feelings, they only record your brain’s activity.
  2. Next, the specialist will attach flat metal discs which contain the electrodes to your head using special glue. The electrodes are connected to another machine which records the brain waves and activity on a computer. An EEG test typically takes 60 minutes for patients who are awake, and up to 3 hours for patients who must be asleep for the test.
  3. For the duration of the test, you will rest comfortably with your eyes closed. At times, the specialist may ask to you to open and close your eyes, stare at a flashing light, and breathe heavily.
  4. While you are taking the EEG, your doctor may also record your body movements on video. This, combined with the results of the EEG, can greatly increase your doctor’s chances of diagnosing and treating your brain condition.
