At Dignity Health, your doctor may use an electroencephalogram test to diagnose or monitor several neurological conditions. An EEG test is commonly used to detect or monitor:
The electroencephalogram is a minimally invasive test that can be done in a Dignity Health hospital or doctor’s office. It usually is performed by an experienced EEG technician, who sends the test results to your doctor. Depending on the purpose of the test, an EEG typically takes one to three hours. In some cases, extended monitoring is necessary.
Prior to receiving an EEG test, your doctor will give you specific instructions on how to prepare. In general, you should:
During your EEG test, the technician will place adhesive-backed electrodes on your scalp and possibly your face. The electrodes connect to a machine that records your brain activity. You will be asked to lie still with your eyes closed. You may also be asked to perform certain activities during the test, such as breathing fast or looking at a flashing strobe light.
An EEG test is generally safe. However, the EEG technician is trained to respond if parts of the procedure trigger a seizure, such as viewing a strobe light.
You may return to normal activities following an EEG. If you experience a seizure during the test, the technician will give you specific instructions about how to proceed.
The electroencephalogram test can help your doctor determine if you have a seizure disorder or other brain condition. Once this diagnosis has been established, your Dignity Health neurological team can create your personalized treatment plan.
