EEG testing Q & A
What is an EEG?
An EEG is a test that evaluates the electrical activity in your brain. It tracks and records your brain wave patterns, which provide information about the way your brain cells communicate through electrical impulses.
Your brain waves create a recording that’s represented as a wavy line with peaks and valleys. Your doctor can evaluate the report to identify abnormalities that could indicate a sleep disorder, seizures, or other brain disorders.
Why would I need an EEG?
EEGs are used to assess your brain health and identify signs of brain disorders and injuries. Your physician might recommend an EEG if they suspect a condition like:
- Sleep disorders
- Epilepsy and other seizure disorders
- Head injuries
- Brain inflammation
- Brain tumors
- Memory problems
Academy Diagnostics provides EEGs from the convenience and comfort of their offices for your convenience. They serve patients of all ages and specialize in pediatric testing.
Do I need to do anything to prepare for an EEG?
Your physician provides customized instructions on how to prepare for your EEG. For example, depending on the reason for your test, they might ask you to sleep as little as possible the night before.
You should also have clean, dry hair with no products on the day of your EEG. You should also avoid caffeine for at least eight hours before your test.
What happens during an EEG?
An EEG is a noninvasive, painless test that is very safe. When you have an EEG, a medical technician attaches electrodes to your head and scalp. The electrodes detect the electrical activity in your brain and transmit the information to equipment that records the data.
EEGs usually take 30-60 minutes. You rest on a comfortable chair or treatment bed throughout the test. Depending on the reason you need the EEG, your technician might ask you to do things such as look at stimuli, close your eyes, or take deep breaths.
If necessary, Academy Diagnostics also offers long-term video EEG/seizure monitoring. These tests take 12-24 hours. A close friend or family member stays with you throughout your assessment to alert the technician to the warning signs of a seizure. The test is similar to a standard EEG, but you spend more time in the comfortable Academy Diagnostics offices.
