Overview
Why It's Done
- An EEG can determine changes in brain activity that might be useful in diagnosing brain disorders, especially epilepsy or another seizure disorder. An EEGmight also be helpful for diagnosing or treating the following disorders: 1. Brain tumor 2. Brain damage from head injury 3. Brain dysfunction that can have a variety of causes (encephalopathy) 4. Inflammation of the brain (en…
Risks
- EEGsare safe and painless. Sometimes seizures are intentionally triggered in people with epilepsy during the test, but appropriate medical care is provided if needed.
How You Prepare
- Food and medications
1. Avoid anything with caffeine on the day of the test because it can affect the test results. 2. Take your usual medications unless instructed otherwise. - Other precautions
1. Wash your hair the night before or the day of the test, but don't use conditioners, hair creams, sprays or styling gels. Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp. 2. If you're supposed to sleep during your EEGtest, your doct…
