Emory Decatur Hospital and Emory Hillandale Hospital offer electroencephalogram (EEG), a painless test to detect problems in the electrical activity of the brain. An EEG test is used to help diagnose if you're having seizures and if so, the type of seizure. An EEG test also is used to find the causes of confusion and to evaluate head injuries, tumors, infections, degenerative diseases such as Alzheimer's disease, and abnormal changes in body chemistry that affect the brain.

An EEG test is used to evaluate problems with sleep and to investigate periods of unconsciousness. An EEG may be done to show that the brain has no activity, in the case of someone in a deep coma. It can be helpful when trying to decide if someone is brain dead. EEGs are interpreted by a neurologists and a report will be sent to the primary care of referring physician.

Preparing for Your EEG Test in Atlanta at Emory Decatur Hospital and Emory Hillandale Hospital

You will need to wash your hair the night before the test. Do not use any oils, sprays or conditioner on your hair before this test. Avoid all foods containing caffeine for 8 hours before the test. Ask your doctor about any medications you are taking.

An EEG test takes approximately 1 hour to 1 ½ hours to complete. The technologist will measure your head and apply electrodes to your scalp using a paste-like substance. During the test, activation procedures are used such as hyperventilation and Photic stimulation. These activation procedures can help reveal different brain wave patterns that are useful in diagnoses. You will be asked to close your eyes and relax, and you usually fall asleep during the test.
