At Dignity Health, our neurologists can perform electroencephalography (EEG) to evaluate electrical activity in the brain. An electroencephalogram is a painless, minimally invasive diagnostic test.
If you would like to learn more about an EEG in Arizona, meet with a skilled neurologist at Dignity Health. To request an appointment, Find a Doctor today.
Neurologists at Dignity Health often use electroencephalography to diagnose or monitor health conditions that affect brain activity. An EEG may be recommended to monitor or detect:
Our compassionate specialists take a team approach to treating disorders of the brain and nervous system at St. Joseph’s, Chandler Regional Medical Center, and Mercy Gilbert Medical Center.
Before you go in for your EEG, you will be given special instructions on how to prepare for the test. This may include the following:
An EEG may be performed at a Dignity Health hospital, outpatient center, or doctor’s office. This minimally invasive test is given by a skilled EEG technician. Depending on the purpose of the EEG, it may last from one hour to several hours. If your EEG is part of a sleep study, the test may take eight hours or more.
During an EEG, you will lie down on a bed or recliner. The technician will place sticky electrodes over your scalp and, sometimes, certain areas of your face. The electrodes connect to a recording machine with wires. You must lie still with your eyes closed during the test. The technician may ask you to do certain things during the EEG, such as breathe fast or look at a flashing strobe light.
Sometimes, your doctor may need to perform a longer EEG. If so, you will be asked to wear an device that records your brain activity for up to three days while you go about your normal routine.
Once your test is complete, you will be able to return to your normal routine. If you have a seizure during the EEG, the technician will give you special instructions on how to proceed. This test will help your doctor determine whether or not you have a seizure disorder or other type of brain condition. An EEG will help guide your treatment options moving forward.
In collaboration with the Barrow Neurological Institute, Dignity Health offers a complete range of neurological testing and treatment, including EEG in Arizona.
