What to Expect During an EEG Test
Curious about how EEG tests work? Discover exactly what to expect during an EEG test, how to prepare, and what happens afterward at Kampala EEG Laboratory and Sleep Center.
When your doctor recommends an EEG (electroencephalogram), it’s normal to feel uncertain or nervous — especially if it’s your first time. At Kampala EEG Laboratory and Sleep Center, we understand how important it is to feel comfortable and informed. That’s why we’re here to walk you through what an EEG test looks like, step-by-step.
Whether you’re being tested for seizures, sleep problems, or unexplained episodes of confusion, knowing what to expect can ease your mind and help you feel more prepared.
What Is an EEG Test and Why It’s Done
An EEG test measures electrical activity in your brain using small electrodes attached to your scalp. It’s safe, non-invasive, and does not involve any pain or injections. Doctors usually recommend it if you’re experiencing symptoms like:
- Seizures
- Frequent blackouts or fainting
- Memory issues
- Sleep problems
- Unexplained confusion
The goal is to help your doctor understand how your brain is functioning and what might be causing your symptoms.
Before the EEG Test: How to Prepare
Knowing how to prepare for an EEG can make the experience much smoother. Here are a few important tips:
- Wash your hair the night before the test. Don’t use conditioner or hair products.
- Avoid caffeine or energy drinks for at least 8 hours before the test.
- Bring a list of your medications, and tell the technician if you’re taking any that affect the brain.
- Get enough sleep, unless your doctor requests a sleep-deprived EEG (where you're asked to stay awake the night before).
- Tip: Wear comfortable clothes. You don’t need to undress for the test.
During the EEG Test: What Happens Step by Step
At Kampala EEG Laboratory and Sleep Center, our trained technicians make the process simple and calming. Here’s what will happen:
Electrode Placement
You’ll lie down comfortably. The technician will apply around 20 small, flat discs (electrodes) to your scalp using a special gel. It doesn’t hurt.Recording Starts
You’ll be asked to relax, lie still, and sometimes do simple tasks like breathing deeply or looking at flashing lights.Length of the Test
The entire procedure usually takes 30 to 60 minutes. For a sleep EEG, it may take longer.No Pain or Shocks
The EEG only records your brain’s activity — it doesn’t send anything into your brain. You won’t feel anything.
After the EEG Test: What to Expect
Once the test is done:
The technician will remove the electrodes and clean your scalp.
You can go home and resume your normal activities right away.
The results are sent to a specialist who will interpret the patterns and send a report to your doctor.
- If your test was sleep-deprived, avoid driving or operating machines until you’ve had rest.
