What is an EEG?

What is an EEG? | NASA MRI Blog

During an EEG a series of small metal discs with connecting wires are placed on the scalp. These electrodes determine the electrical activity of the brain. Brain cells use electrical impulses to communicate, and an EEG records these brain patterns. A review of these patterns can help to detect a variety of conditions.

This rather simple procedure is completed by specialized technicians, and usually lasts between 30 and 60 minutes. Once the electrodes are placed you will be asked to lie down or sit back. During the procedure you may be asked to close your eyes, breathe deeply, or look at patterns on a screen.

What does an EEG Diagnose?

An EEG is used to diagnose multiple disorders, which can include:

  • Head Injury
  • Brain Tumor
  • Epilepsy
  • Additional Seizure Disorders
  • Stroke
  • Brain Inflammation
  • Sleep Disorders
  • Dementia

Is an EEG Dangerous?

An EEG is a painless and safe procedure. If an EEG is performed to help diagnose epilepsy, a seizure may be triggered. If this is required your medical team will provide the needed medical care.

Preparing for your EEG

  • You can wash your hair the day of the test, but do not use conditioner, or creams. Additionally, do not add hair gel or hair sprays. These products will make it difficult to adhere the electrodes to your scalp.
  • Avoid caffeine
  • Be sure that your physician knows all of the medications you may be taking. You should be able to continue taking most medications, unless instructed otherwise.
