What Should You Expect for your EEG Test Preparation?
Good long-term EEG test preparation starts at home. Please arrive with clean, dry hair and avoid using any styling products on the day of your test. This ensures good electrode contact.
Bring a list of all medications you are currently taking to your appointment.
Wear comfortable clothing! A shirt with buttons or a zipper is ideal, since it can be removed easily if you get too hot or cold during testing. This prevents disruption to the electrodes.
Avoid caffeine and, if instructed by your physician, certain medications prior to the test. Caffeine is a stimulant that can alter the brain’s electrical activity.
The EEG Hookup Process
During the hookup process, you will be asked to lie down and relax. A technologist will measure your head using the 10–20 system, then gently scrub your scalp with a mild adhesive gel. Up to 26 electrodes will be applied with conductive paste.
The electrodes will be secured with medical glue, and your head will be wrapped to keep the leads in place. You will be continuously monitored while your brain’s electrical signals are recorded for up to 24 hours, capturing both wakefulness and sleep states.
What to Expect During the EEG Test
Bring activities to help pass the time. You may:
- Read a book or magazine
- Play cards or board games
- Watch TV or movies
- Listen to music or podcasts
Avoid any activity that causes sweating or physical exertion.
You will not be able to shower during the test, but you can eat and drink normally. Continue taking your prescribed medications as instructed by your physician. Please do not chew gum, as it can create artifacts that interfere with your EEG recording.
After Your EEG Test Is Completed
Once the test is finished, the electrodes will be removed. The adhesive glue may leave your hair messy, so you may need to wash it thoroughly with shampoo and conditioner.
Final Thoughts on Long-Term EEG Test Preparation
A long-term EEG test may sound overwhelming at first, but with the right preparation it can be a smooth and comfortable experience. Following these steps—clean hair, no caffeine, bringing your medication list, and packing some quiet activities—will help ensure accurate results and make the process easier for you. If you have questions about your specific situation, don’t hesitate to reach out to your physician or the testing center ahead of time.
