What Is An Electroencephalogram (EEG)?
An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors are attached to your scalp to monitor your brain's electrical activity and transmitted to a polygraph. It is a painless test used to diagnose sleep disorders, such as narcolepsy.
What to Expect
Your Sleep Technologist will be at our site to greet you when you arrive. After you make yourself comfortable, your Technologist will take a brief history, explain the testing procedure, and answer any questions you may have prior to applying the sensors for your study. This procedure is completely painless and generally takes about 40 minutes to make sure everything is placed correctly.
After all the sensors are applied and checked, the technologist will do a few tests that may include fast, deep breathing (hyperventilation), as well as strobe light testing (photic stimulation). When these tests are done, you’ll be asked to lay still with your eyes closed, and try to fall asleep. You will be monitored remotely--no one will be in your room watching you.
When the study is done, the technologist will wake you and remove the wires and sensors. You will then be able to take a shower (at certain locations) and be on your way.
