Electroencephalogram (EEG)

An electroencephalogram (EEG) is a test used to evaluate electrical activity in the brain. An EEG is used to detect problems in the electrical activity of the brain that may be associated with certain brain disorders. The measurements given by an EEG are used to confirm or rule out various conditions, such as:

  • Seizure disorders (such as epilepsy)
  • Head injury
  • Encephalitis (inflammation of the brain)
  • Brain tumor
  • Encephalopathy (disease that causes brain dysfunction)
  • Memory problems
  • Sleep disorders
  • Stroke
  • Dementia


Life Sciences performs two types of EEG studies:

  • Routine EEG – this EEG study typically takes place in your physician’s office or at your home. The Prolong study approximately lasts a little over an hour.
  • 24, 48, or 72 Hour AV EEG – these ambulatory EEG includes video and takes place in the convenience of your home for the length of time ordered by the ordering physician.
