The Why, How, Where, Risks and Cost of EEG Test in Nigeria.

An EEG known as electroencephalogram is full terms is an investigative device used to check the electrical activity of the brain. It helps detect problems related to brain function. An EEG tracks and records brain wave patterns.

It is an investigative procedure for both adults and children but procedure and interpretation of results are the same.However, it is most times done for children.

Why is EEG Done?    

According to KIDSHEALTH, most EEGs are done to diagnose and monitor seizure disorders (epilepsy). EEGs also can identify causes of other problems, such as sleep disorders and changes in behavior. They are sometimes used to evaluate brain activity after a severe head injury or before a heart transplant or liver transplant.


If your child is having an EEG, preparation is very minimal and does not require much to do from your part . Ensure you remove or clean oils, sprays, and conditioner from your child’s hair to help the electrodes stick to the scalp.

Your doctor may recommend that your child stop taking certain medications before the test. It’s often recommended that children should not have caffeine up to 8-10 hours before the test.

Caffeine has been shown to interfere with the actual reading of EEG and can cause wrong results or interpretations. If it’s necessary for your child to sleep during the EEG, the doctor will suggest ways to help make this easier.

How and where is it done?

An EEG can be done in the doctor’s office, a laboratory, or a hospital. Your child will be asked to lie on a bed or sit in a chair depending on the doctor’s discretion. The electrical signals (or activity) from the brain are converted into wavy lines on a computer screen and interpreted.

Interpretation of Results
