ABOUT YOUR BRAIN
In your brain, cells generate electrical impulses that carry messages to all parts of the body through a complex system of nerves. The brain receives information when light, sound, etc., produce electrical impulses in nerves leading to the brain. The brain sends out electrical impulses that control actions such as muscle coordination, speech, and vision. These electrical messages to and from the brain can become altered by illness or injury. This test can help detect the locations and cause of the problem.
ABOUT THE 24-HOUR AMBULATORY EEG
A 24-hour ambulatory EEG provides important information about the health and functioning of the brain. Our EEG technologists will apply electrodes with adhesive to key locations on your head. These electrodes have wires leading to a portable box. The box picks up electrical impulses in your brain and records the activity onto a computerized disc (2 hours).
You may engage in your normal activities including eating and sleeping before, during, and after the test, except for showering. Do not shower with this equipment on. On the day of the test, please take your medications as you normally do. This test is painless, and there is no radiation involved. Please be sure to wear comfortable clothing. It is also important that you wear a button-down shirt, since this prevents having to pull clothing up over the electrodes. You will be asked to keep a 24-hour diary of your activities during the recording. A return trip will be scheduled for the following day to remove the equipment and electrodes (which will take approximately 15 to 20 minutes).
