Look below for the answers to our most frequently asked questions about the EEG test:
What does EEG mean?
EEG stands for electroencephalogram.
What is an EEG?
An EEG is a diagnostic test to measure brain electricity.
How do I schedule an EEG?
Your healthcare provider in Neurology will fax your order for this test to the hospital of your choosing. Once it’s received, the hospital will call you to set up an appointment.
How long does the test take?
The test takes several hours to complete.
Can I eat and drink before my EEG?
Yes, you may eat and drink before the test. However, please avoid caffeine on the morning of the test.
What should I do with my hair?
Your hair should be clean and dry. Please do not use any gel or hairspray products beforehand.
Are you going to shave my head?
No, we won’t shave your head or cut your hair.
Does the EEG test hurt?
The EEG may cause some minor discomfort during hookup. Your head will be measured and marked, and then each area will be gently cleaned, which can feel scratchy. At that point, a wire is placed on your scalp.
What will happen during the test?
In the first 10-15 minutes of the test, you’ll participate in activities such as blinking, counting a flashing light and a breathing exercise. You’ll then be able to sleep and relax for the rest of the time.
Will I be able to go back to work or school after my EEG?
Often yes, but you may feel tired and have leftover residue in your hair that requires a shower to remove.
Do I need to prepare for my appointment?
Yes. The following instructions will help obtain the best results and experience with the EEG.
- Arrive with clean, dry hair without any gel or hairspray.
- Sleep no more than 4-5 hours the night before you come in.
- Avoid caffeine products such as tea, coffee, and cola the morning of your test. Breakfast, snacks and medications are okay.
- Please bring a list of all medications with you.
Will I receive my results right away?
No. A technologist will perform your EEG. The study will then be sent to your neurologist to be interpreted and officially read.
