Routine and Sleep EEG Studies
Your brain cells communicate with each other by producing tiny electrical signals called impulses. An electroencephalogram (EEG) measures this activity. There are two types of EEG studies: routine and sleep. Each test measures the electrical activity in your brain.
At St. Luke’s, your path to feeling better begins with advanced diagnostics. Our team members are experts in EEG and work to make your experience as comfortable and efficient as possible. It’s natural to have questions if you have a referral for an EEG. We’ve gathered information about the test and what you can expect from your visit with us.
What to Expect During Your EEG
To start, the technician will measure and mark your scalp with a wax marker. Next, we’ll place small gold-plated disks on your scalp using a washable paste. During the test, while you relax in a recliner with your feet up, head back and eyes closed, the disks record your brain’s electrical impulses.
When the test is done, your technician will remove the disks, paste and marks. You’ll be able to resume your normal activities. One of our neurologists will interpret your test results and share the data with your doctor.
Before Your Routine EEG
Routine EMG studies don’t require any special preparation. There are a few things to keep in mind:
- Eat normally, and take your usual medications
- Don’t skip meals unless instructed
- Remove any hairpieces like toupees, weaves or hair extensions
Before Your Sleep EEG
If you’re having a sleep EEG, make sure to take these steps the night before the test:
- Avoid caffeine with your evening meal (no coffee, tea, caffeinated soda, chocolate, etc.).
- Go to bed at your usual time.
- Get up by 2 a.m. on the day of your test, and stay awake.
- Eat breakfast and take your usual medications (except sedatives) unless your doctor tells you otherwise.
- Wear comfortable clothes. You will be sleeping on a recliner and not a bed.
