What Is An Electroencephalogram (EEG)?
An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. It is a painless test used to diagnose seizure disorders, such as epilepsy.
When you arrive for your EEG, a Registered Polysomnographic Technologist (RPSGT) or Registered Respiratory Therapist (RRT) will be at the site to greet you and show you to your room. After you make yourself comfortable, your technologist will take a brief history, explain the study process, and answer any questions you may have. The next step is to apply the sensors, which is painless and takes about 40 minutes.

Getting Ready
First, the technologist will use stickers to affix leads on your chest and abdomen.
Next, your head will be marked and measured with a paper ruler and a grease pencil. This is done because each electrode needs to be placed in a precise location in order to accurately measure your brain waves. Once this is complete, a skin prep jelly will be applied to clean your scalp for the electrodes. This jelly removes any excess oils or skin cells in order to obtain a clear reading of your brain waves.
Lastly, the electrodes are placed on the surface of your scalp with a small amount of paste. The prep, paste, and tape are hypoallergenic.

Testing
After all the sensors are applied and checked, the technologist will do a series of tests to obtain a baseline of your brain activity. These tests may include fast, shallow breathing (hyperventilation), as well as strobe light testing (photic stimulation). When these tests are done, you’ll be asked to lie still with your eyes closed and try to fall asleep.
Your technologist will monitor your testing throughout the study and will be available to answer questions and ensure you’re comfortable.

All Done, Now What?
Once your study is complete, the technologist will remove the electrodes and leads. Any remaining paste or marks can be easily washed out using warm water and shampoo.
At your follow-up appointment, you will receive your EEG results and discuss them with your provider.

Set Time Aside
This is an overnight test. Plan to be at our sleep center overnight until approximately 7 a.m. the next morning.
Wash and Dry Your Hair
Wash and dry your hair thoroughly but do not use conditioners or other hair products.
Hair Accessories
Remove any hair weaves or extensions. We cannot do testing if you have either of these.
Acrylic or Applied Nails
If you have acrylic nails or applied ("fake") nails an index fingernail needs to be removed for the oxygen reading. If you have gel nail polish, the polish from one of the index fingers will need to be removed. Regular nail polish is fine. The oximeter does not read through acrylic or applied nails, nor gel polish.
What Should I Wear?
Wear comfortable, loose-fitting, two-piece clothing. You must wear pajamas or two-piece clothing for the test.
