Has your doctor scheduled an EEG (electroencephalogram), and you’re wondering how to prepare? It’s completely normal to feel a little unsure before any medical test. But don’t worry—an EEG is painless, non-invasive, and straightforward.

Your preparation can directly affect the accuracy of the test results, so it’s important to follow the right steps. In this guide, we’ll walk you through everything you need to know, from how to prepare to what happens during and after the procedure.

Let’s get started!

What Is an EEG and Why Is It Performed?

An EEG measures the brain’s electrical activity through small sensors (electrodes) placed on your scalp. This test is often used to detect irregular brain wave patterns and diagnose various neurological conditions.

How Does an EEG Work?

Your brain cells communicate using electrical impulses. These impulses create patterns that an EEG can record. By analyzing these patterns, doctors can determine whether your brain activity is functioning as expected.

Common Conditions Diagnosed with an EEG

Doctors may recommend an EEG if they suspect conditions such as:

• Epilepsy – EEGs help identify seizure activity and determine the best treatment.
• Sleep disorders – Conditions like insomnia, sleep apnea, and narcolepsy may show abnormal brain activity.
• Stroke or head injuries – An EEG can detect changes in brain function following trauma.
• Dementia and cognitive decline – EEGs help doctors assess memory and cognitive issues.

How to Prepare for an EEG?

Proper EEG prep instructions are essential to getting accurate results. Here’s what you need to do:

1. Keep Your Hair Clean and Free of Products

Electrodes must adhere properly to your scalp, so your hair should be clean and dry.
✔️ Wash your hair the night before using mild shampoo.
❌ Avoid using conditioner, oils, or styling products, as they can interfere with the test.

2. Avoid Caffeine and Nicotine Before the Test

Caffeine and nicotine can alter brain activity, so avoid them for at least 8–12 hours before your EEG.
✔️ Skip coffee, tea, soda, energy drinks, and nicotine-based products.

3. Take Your Prescribed Medications as Directed

Some medications can impact brain activity.
✔️ Take your medications normally unless instructed otherwise by your doctor.
✔️ Bring a list of medications you’re currently taking to your appointment.

4. Follow Sleep Guidelines if Required

In some cases, sleep deprivation is necessary for the test.
✔️ Stay awake most of the night before the EEG.
✔️ Get only 4–5 hours of sleep if your doctor requests it.

Why? Sleep deprivation can make abnormal brain activity easier to detect during the test.

What to Expect on the Day of Your EEG

1. Arriving at the EEG Testing Facility

• Arrive 15–30 minutes early to complete any necessary paperwork.
• Wear comfortable clothes, and avoid wearing metal accessories like earrings or glasses.

2. Placement of Electrodes and Setup

• A technician will place small metal electrodes on your scalp using a special adhesive.
• The electrodes do not cause pain; they simply record your brain’s electrical activity.
• The test usually takes 30–60 minutes.

3. During the Test: What Happens?

• You’ll be asked to relax and stay still while recordings are taken.
• You may be asked to breathe deeply, close your eyes, or look at flashing lights to test different responses.
• If your EEG includes a sleep test, you may be allowed to take a short nap.
