Electroencephalogram (EEG) Overview. An electroencephalogram (EEG) is a noninvasive test that records electrical patterns in your brain. The test is used to help diagnose conditions such as seizures, epilepsy, head injuries, dizziness, headaches, brain tumors and sleeping problems. It can also be used to confirm brain death.
Brain cells communicate with each other by producing tiny electrical signals, called impulses. An EEG measures this activity. The test is done by a EEG specialist in your doctor's office or at a hospital or laboratory. You will be asked to lie on your back on a bed or in a reclining chair. Flat metal disks called electrodes are placed all over your scalp. The disks are held in place with a sticky paste.
