Understanding Electroencephalogram (EEG)
An Electroencephalogram, or EEG, is a simple, painless test that records the electrical activity of your brain using small sensors placed on your scalp. Your doctor may refer you for an EEG to help understand what is happening in your brain — for example, if you have been having seizures, fainting episodes, episodes of staring blankly, or other unusual symptoms. The test helps doctors find the cause of these symptoms so they can give you the right treatment.
Common Symptoms / Concerns for Electroencephalogram (EEG)
When to Seek Professional Care
Book an evaluation with a healthcare provider immediately if you experience or present with:
- A seizure that lasts more than 5 minutes without stopping
- Loss of consciousness that does not improve quickly
- A second seizure happening within 24 hours
- A seizure in someone who has never had one before
- Difficulty breathing, speaking, or moving after a seizure
- A child who has a seizure with a very high fever
- Sudden severe confusion or unusual behaviour that does not go away
- Repeated fainting episodes with no clear cause
What to Expect During Your Medical Consultation
During your EEG appointment, a trained health worker will gently attach small sensors to your scalp using a safe paste — this does not hurt at all. You will be asked to lie still and relax, and at times you may be asked to breathe deeply or look at a flickering light so the doctor can see how your brain responds. The whole test usually takes between 30 and 60 minutes, and you can go home the same day.

Frequently Asked Questions
What is an EEG used for?
An EEG is used to check the electrical activity of your brain and help doctors find the cause of symptoms like seizures, fainting, or episodes of staring blankly. It is commonly used to diagnose epilepsy and other conditions that affect the brain. The results help your doctor decide on the best treatment for you.
Is an EEG painful or dangerous?
No, an EEG is completely painless and very safe. The sensors placed on your scalp only record signals from your brain — they do not send any electricity into your body. Many people find the test relaxing, and there are no needles or injections involved.
How do I prepare for an EEG test?
Wash your hair the night before or on the morning of your appointment, and do not apply any oils, creams, or hair products to your scalp. Your doctor may ask you to avoid caffeine (such as tea, coffee, or energy drinks) on the day of the test. In some cases, you may be asked to sleep less the night before so your brain activity can be recorded more clearly — your doctor will let you know if this applies to you.
What do the EEG results mean?
After the test, a doctor will study the recording of your brain activity and look for any patterns that are unusual. They will then explain the results to you and what they mean for your health. If something is found, your doctor will discuss the next steps, which may include medication or further tests.
Can epilepsy or seizures be treated after an EEG diagnosis?
Yes, epilepsy and seizures can often be managed very well with the right treatment. Many people with epilepsy take medication that reduces or stops their seizures completely, allowing them to live normal, active lives. Your doctor will work with you to find the best treatment plan based on your EEG results and your overall health.
