Routine EEG Testing for Neurological Evaluation
An Electroencephalogram (EEG) is a noninvasive test that records electrical activity in the brain. It is one of the most important tools in diagnosing epilepsy, seizures, and other neurological conditions. At Georgia Epilepsy & Neurology Institute, our team performs precise, comfortable EEG testing for patients of all ages.
Supervised by Dr. Ki Hyeong Lee, MD and Dr. Joo Hee Seo, MD, EEG testing helps identify abnormal brainwave patterns and provides valuable information to guide diagnosis and treatment.
What Is a Routine EEG?
A routine EEG involves placing small electrodes on the scalp to record brainwave activity. The test measures how the brain functions during rest and simple stimulation such as deep breathing or flashing lights. It is painless and usually completed within 30 to 60 minutes.
Why an EEG May Be Recommended
Your doctor may recommend an EEG if you experience:
- Seizures or unexplained loss of awareness
- Fainting or confusion
- Frequent headaches or visual disturbances
- Sleep or movement abnormalities
- Behavioral or developmental delays in children
An EEG helps determine if these symptoms are due to abnormal electrical activity in the brain.
The Testing Process
- The scalp is cleaned and electrodes are applied using a conductive gel.
- You may be asked to rest quietly or follow light commands during the test.
- The EEG records your brainwaves in real time.
- The data is analyzed by Dr. Lee or Dr. Seo, who interpret results and create a personalized care plan.
Patients can return to normal activities immediately afterward.
FAQs About Routine EEG
Q: Is an EEG safe?
A: Yes. EEG testing is completely safe and noninvasive, with no electrical current applied to the body.
Q: Do I need to prepare for an EEG?
A: Avoid caffeine and ensure your hair is clean and free of oils or products. Specific instructions will be provided before your appointment.
Q: Will I need sedation?
A: No sedation is required. Patients remain awake for routine EEGs.
Q: Can an EEG detect all types of seizures?
A: While not every seizure occurs during the test, EEG patterns often reveal underlying abnormalities that confirm diagnosis.
Q: How are EEG results used?
A: EEG findings guide diagnosis for epilepsy, sleep disorders, and other neurological conditions, helping doctors tailor treatment precisely.
