An electroencephalogram or EEG is a test to measure the electrical activity of the brain. The EEG can help the doctors diagnose or monitor a number of health conditions including: brain diseases, head injuries, infections, tumors and seizures. It can also evaluate many other neurological issues.

How is the test performed?

The patient will be asked to lie back. Flat metal disks called electrodes are placed all over the scalp. The electrodes are connected by wires to recording machinery. The recording device changes the electrical signals into patterns that can be seen on a computer. It looks like a bunch of wavy lines which tell the physician the patterns of electrical activity.

How should you prepare for the test?

The doctor may ask you to stop taking some medications before the test. Patients should not eat or drink foods that have caffeine or extra sugars for 12 hours before the test. Since the electrodes area attached to your scalp, make sure your hair is clean and free of sprays, oils, creams and lotions. If the EEG is to be done when the child is asleep, the doctor may ask you to keep your child from taking naps before the test. Wearing a button up type shirt is preferred verse a T-shirt on the day of testing.
