What is an EEG?
This test helps us to find out more about the kind of seizures or events you are having. During the test, a camera records your behavior. This is paired with an EEG recording of your brain wave activity. Sometimes, movements may look like seizures, but they are not. If you have seizures, this study will help us learn how strong they are and how often they occur. It will also help us find out what part of the brain the seizures are coming from.
This test will also help us decide if you are having silent seizures. These are seizures that occur without any physical signs. Changes can be seen on the EEG with this type of seizure.
The test is painless. There will not be any shots or special medicines used. Small metal disks will be placed on your scalp. Your hair will be moved out of the way. These disks will be held in place using special paste made just for this test.
This test may require pre-authorization from your insurance company. Not all insurance plans will cover this test. Please call your insurance to find out if this test is covered. You may also need a referral from your primary doctor. If so, ask your primary doctor for this and send it to the insurance company. This will need to be done as soon as possible. It often takes 2-4 weeks to find out about coverage. Your insurer will contact you after they make their decision.
