An EEG test records the electrical activity of your brain. The test involves pasting small electrodes connected to a computer that records brain activity to your scalp. This noninvasive test is useful for diagnosing seizures and evaluating several other conditions.
How to Prepare for the EEG:
- Wash hair the night before or the day of the test.
- Do not use any styling products such as hairspray or oil.
- Before your test, remove any hair weaves, extensions, braids, or etc.
- Do not consume caffeine-containing food or beverages (e.g., coffee, tea, colas, chocolate) for at least 6 hours before the scheduled test.
- If scheduled for a “sleep-deprived EEG, do not sleep more than four hours the night before the test.
- Take regular medications unless otherwise instructed.
