Frequently Asked Questions

What is an EEG test?

EEG (Electroencephalogram) is a non-invasive test that records the electrical activity of the brain using small electrodes placed on the scalp. It helps evaluate brain function and detect abnormalities.

Why is an EEG test done?

An EEG is commonly performed to diagnose epilepsy, seizures, sleep disorders, brain infections, head injuries, and other neurological conditions affecting brain activity.

How should I prepare for an EEG?

Wash your hair the night before the test and avoid using hair oils, sprays, or conditioners. Continue taking medications unless instructed otherwise by your doctor.

Do I need to fast before an EEG?

Fasting is usually not required for a routine EEG. However, your doctor may give specific instructions depending on your condition.

Is an EEG test safe?

Yes, EEG is completely safe and painless. It only records the brain’s natural electrical activity and does not send electricity into the body.

What happens during an EEG test?

During the test, small electrodes are attached to your scalp using a conductive gel or paste. You will be asked to relax, and sometimes perform simple tasks like deep breathing or looking at flashing lights while the brain activity is recorded.

How long does an EEG test take?

A routine EEG usually takes about 20 to 40 minutes. In some cases, longer monitoring may be required depending on the condition being evaluated.

Is EEG painful?

No, the EEG test is painless. You may feel slight discomfort when the electrodes are removed, but the procedure itself does not cause pain.

When will I get my EEG results?

The recorded data is analysed by a neurologist, and the report is usually available within the same day or a few days depending on the facility.

Can EEG detect all brain problems?

EEG is highly effective for detecting seizure disorders and abnormalities in brain electrical activity, but it may not detect structural issues. Additional imaging tests like MRI or CT scans may be required for complete evaluation.
