Tips to Prepare for Your EEG to See If You’re at Risk for Another Seizure

Seizures impact the lives of approximately 3.4 million people in the United States, affecting everything from daily routines to overall health. The unpredictable nature of seizures can make them challenging to manage, but with the right treatment plan, patients diagnosed with seizure disorders can live more fully and minimize the impact on their lives.  

At Neurology Specialists of Albuquerque, our board-certified neurologist Timothy Ownbey, DO, is dedicated to helping patients achieve better control over their seizures through comprehensive neurological care. Electroencephalograms (EEGs) are one of the key diagnostic tools we use to assess your risk for future seizures. This test is painless and quick, but taking a few simple steps ahead of time is essential for getting the most accurate results. If you’re scheduled for an upcoming EEG, read on for our tips to guide you through the process.

The role of an EEG in managing seizure risks

EEGs play a crucial role in diagnosing and managing epilepsy. By analyzing the electrical activity in your brain, EEG results can help confirm an epilepsy diagnosis or assist Dr. Ownbey in adjusting your antiseizure medication.

Typically, EEGs involve attaching electrodes to the scalp to monitor brain wave patterns. After a first seizure, doctors frequently recommend an EEG to detect any brain activity changes.

While an EEG can only capture seizures that happen during the test, it may also detect abnormal brain waves between seizures, known as interictal epileptiform discharges (IEDs). These IEDs are commonly observed in individuals with epilepsy. Detecting changes in brain activity early helps assist risk for another seizure.

Prioritize sleep

Your brain's electrical activity is closely linked to your sleep patterns, and this makes it crucial to get enough sleep before your EEG. In some cases, our team may instruct you to limit your sleep since certain types of brain activity become more apparent when you haven’t had restorative sleep. If this applies to your test, please follow the specific guidelines our clinical team provides.

Follow medication guidelines

Follow any medication instructions provided by our team prior to your EEG. While most medications should be taken as usual, some may need to be adjusted or temporarily discontinued. Be sure to inform Dr. Ownbey of all medications and supplements you’re  currently taking, and follow any guidance provided.

Ensure clean hair

Before your EEG, wash your hair thoroughly and avoid using hair products such as gels, sprays, or oils. Clean hair helps ensure that the electrodes can be securely placed on your scalp, leading to more accurate results.

Avoid caffeine

On the day of your EEG, it’s recommended to avoid consuming caffeinated beverages, including coffee, tea, and energy drinks. Caffeine can influence brain activity and potentially affect the accuracy of the test results. Opt for water or other noncaffeinated options prior to your appointment.

Wear appropriate clothing

While the EEG is noninvasive and painless, you will need to remain still during the test. Wearing comfortable, loose-fitting clothing will help you stay relaxed throughout the procedure. However, please avoid clothing with metal fasteners, such as zippers or buttons, as metal can interfere with the EEG signals.

Eat a light meal

Having a light meal before your EEG is recommended. Skipping meals can lead to low blood sugar, which may affect the test results. Eating something light and balanced will help you remain comfortable and focused during the procedure.

Arrive early and stay calm

Plan to arrive at our office a little early to allow yourself time to settle in before the test begins. Taking a few moments to relax can help reduce any anxiety, contributing to more accurate results.

Preparing for your EEG with these guidelines will help ensure that it goes smoothly, and that the results are reliable.
