Electroencephalogram (EEG)
An electroencephalogram (EEG) is a non-invasive test that measures electrical activity in the brain using small, metal discs (electrodes) attached to your scalp. These electrodes record tiny electrical signals produced by your brain cells. The EEG helps our neurologists diagnose various brain conditions.
How to Prepare:
We want your EEG experience to be as comfortable and accurate as possible. These simple recommendations will help minimize any potential interference and ensure we can effectively measure your brain's electrical activity:
- Wash your hair: Clean hair helps the electrodes adhere properly to your scalp. Avoid using hair products like gels, sprays, or oils.
- Avoid caffeine: Caffeine can interfere with the EEG readings, so it's best to avoid caffeinated beverages like coffee, tea, and soda for several hours before the test.
- Eat a meal: Having a meal before your EEG can help stabilize your blood sugar levels and prevent you from feeling lightheaded during the procedure.
- Tell your doctor about any medications you are taking: Some medications can affect the EEG results, so it's important to inform your doctor about all medications, including prescription drugs, over-the-counter medications, vitamins, and herbal supplements.
- Relax: While it’s natural to feel a little anxious, try to relax and stay calm during the procedure. The EEG is a painless and safe test.
What to Expect?
During the EEG, you will typically lie down or sit in a comfortable chair. A technician will carefully measure your head and mark the locations where the electrodes will be placed. They will then apply a special gel to each electrode and attach it to your scalp. Once all the electrodes are in place, you will be asked to relax and close your eyes. The EEG machine will then record your brain's electrical activity.
During the test, you may be asked to do certain things, such as:
- Open and close your eyes
- Breathe deeply and rapidly (hyperventilation)
- Look at a flashing light
The entire EEG procedure typically takes about 45-60 minutes.
Why Get an EEG?
Understanding brain activity through an EEG is often the first step toward effective treatment. The information gathered from an EEG helps neurologists develop personalized treatment plans, whether that involves medication, therapy, or other interventions. By accurately diagnosing the underlying condition, EEGs contribute to better patient outcomes.
- Epilepsy and seizures
- Head injuries
- Brain tumors
- Stroke
- Sleep disorders
- Encephalitis
- Dementia
What's Next?
Once the EEG is complete, the electrodes will be gently removed. The data collected during the test will be carefully reviewed by a neurologist, who will look for any abnormal patterns in your brain's electrical activity. This analysis can take some time. You will then be contacted to schedule an appointment to discuss the results and any next steps, which might include further testing or a treatment plan.
