What is EEG?

An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. This activity shows up as wavy lines on an EEG recording.

An EEG is one of the main diagnostic tests for epilepsy. An EEG can also play a role in diagnosing other brain disorders.

What preparation is required before the procedure?

Avoid anything with caffeine on the day of the test because it can affect the test results.

Don’t use conditioners, hair creams, sprays or styling gels. Hair products can make it harder for the sticky patches that hold the electrodes to adhere to your scalp.

Is an appointment required for the procedure?

Yes.

Who will be conducting this test?

A trained technician will be conducting the test for you.

When is the report expected?

Within half an hour of the scan. You shall be informed in case of any unexpected delays.
