Electro-
encephalogram (EEG)
Electroencephalogram (EEG) is a test that records the brain’s electrical activity to help evaluate seizures, spells and other neurologic symptoms.

We have decades of experience caring for patients with Epilepsy, pioneering minimally invasive treatments and leading research for new treatments to improve patient outcomes.
What Is an Electroencephalogram (EEG)?
An electroencephalogram, also called an EEG, is a noninvasive test that measures electrical activity in the brain. Small sensors are placed on the scalp to detect brain wave patterns. Physicians may use an EEG to help evaluate seizures, epilepsy, fainting episodes, confusion, sleep-related events or other symptoms that could be related to brain function.
An EEG does not send electricity into the body. It records signals the brain is already producing. Results are reviewed along with your symptoms, medical history and other tests to help guide diagnosis and care.
Why Choose Baptist Health?
Baptist Health Brain & Spine Care brings together specialists who evaluate complex neurologic symptoms with a patient-centered approach. For patients who may need EEG testing as part of a seizure or epilepsy workup, coordinated care can help connect diagnostic testing with follow-up treatment planning.
Our multidisciplinary team focuses on clear communication, thoughtful evaluation and care tailored to each person’s symptoms and needs. When appropriate, EEG testing may be part of a broader plan that includes neurologic consultation, additional testing and ongoing management.
Frequently Asked Questions
-
An EEG is used to record brain wave activity. Physicians often order it to help evaluate seizures, possible epilepsy, unexplained episodes of altered awareness or other symptoms that may be related to brain function.
-
No. A routine EEG is usually painless. The electrodes sit on the scalp and record activity, but they do not send electricity into your body.
-
The timing depends on the type of EEG ordered. Some tests are relatively short, while others involve longer or repeated monitoring. Your care team can explain what is planned for your visit.
-
You may be asked to arrive with clean hair and avoid hair products. Some patients also receive instructions about sleep, food or medications. Follow the directions provided for your specific test.
-
An EEG can provide important information, but it is usually not the only factor used to make a diagnosis. Physicians interpret EEG results together with your symptoms, history, exam and sometimes imaging or other tests.
-
A normal EEG does not always rule out a seizure disorder or another neurologic condition. Some changes in brain activity may not happen during the recording, so additional evaluation may still be needed.
-
No. An EEG records electrical activity. Imaging tests such as CT or MRI create pictures of the brain’s structure. In some cases, both types of testing are used because they provide different information.
-
Call 911 or go to the Emergency Department right away for a first-time seizure, a seizure lasting more than five minutes, repeated seizures without full recovery, injury during an event, trouble breathing or ongoing confusion.
Pioneering The Cures Of Tomorrow
Our researchers play a vital role in helping us better understand brain and spine disease. They participate in a wide variety of clinical trials dedicated to improving treatments that will ultimately lead to better patient outcomes.
