EEG Test: What You Need to Know

EEG tests are tools that have played a pivotal role in the neuroscience field for many decades. They have the power to diagnose tons of brain-related disorders, including epilepsy and Alzheimer’s disease.

If you’re considering getting an EEG done, there are tons of things you need to learn. This is especially true if you’ve never had one before. Read on to find out what you should know about EEG tests.

What Is an EEG Test?

An Electroencephalography (EEG) test is a type of medical imaging that measures the electric activity of the brain. It is most commonly used as a diagnostic tool to evaluate individuals with neurological or seizure disorders such as epilepsy.

The test utilizes electrodes that are placed on the scalp to capture the electrical activity of the brain in order to produce a visual representation of the electrical activity, known as a brainwave pattern. 

Benefits of an EEG Test

An EEG test is a non-invasive way to assess the activity of the brain. It involves the painless measurement of electrical activity in the brain via electrodes placed on the scalp.

The benefits of an EEG test offer physicians key insights into neurological conditions that would have otherwise gone undetected. With the use of EEG testing, physicians can gain detailed information about the type, location, and extent of neurological problems, which can improve diagnosis and treatment plans. 

Preparing for an EEG Test

Being prepared is important to ensure an accurate and successful test. You may also see these neurological services if you are considering taking them.

Before the EEG test, avoid eating or drinking anything that contains caffeine. It’s also important to let your doctor know if you have taken any medications before your EEG test.

Depending on the type of EEG test, you may need to remove the jewelry and wear a hospital gown. Additionally, some types of EEG tests may require the use of a special dye that is injected into the bloodstream to help pinpoint specific electrical activity within the brain.

Lastly, be sure to get plenty of rest the day before the EEG test, as fatigue can interfere with measurements. When you arrive for the EEG test, be sure to bring a list of current medications, any medical history, and any medical records, if needed.

Exam Structure

During the EEG exam, your scalp will be attached with electrodes to a computer that records the electrical activity. It usually takes around 20-40 minutes to complete the exam.

Once the exam is complete, the electrodes are removed, and the EEG test report will be ready to review. Typically, a neurologist or a trained specialist will review the EEG for any abnormalities in the results. 

Potential Risks of an EEG Test

While the EEG test itself is generally safe, there are some potential risks associated with this test. These include infection, scalp irritation or bleeding, and hair pulling due to the electrodes that are placed on the scalp during the test.

Additionally, some EEG tests require the administration of drugs that can cause side effects like sleepiness, dizziness, and confusion.

Take an EEG Test Now

EEG tests provide incredibly valuable insights into brain activity. They are incredibly safe, non-invasive, and offer quick results. If you are looking for a way to diagnose neurological problems or better understand brain activity, consider an EEG test.
