Question 1

Is an EEG painful?

Accepted Answer

No. An EEG is completely painless. The electrodes simply rest on your scalp and record signals, so you feel no electricity or discomfort.

Question 2

Does an EEG send electricity into my brain?

Accepted Answer

No. This is a common myth. An EEG only listens to and records the brain's own natural electrical activity. Nothing is passed into your body.

Question 3

How should I prepare for an EEG?

Accepted Answer

Wash your hair the night before and avoid oils or sprays, skip caffeine on the day, and continue your usual medicines unless told otherwise. For a sleep-deprived EEG, follow the special sleep instructions provided.

Question 4

What is the difference between an EEG and an MRI or CT scan?

Accepted Answer

An EEG records the brain's electrical function, while an MRI or CT scan shows the brain's structure. They provide different information and are often used together for a complete assessment.

Question 5

Is an EEG safe for children?

Accepted Answer

Yes. An EEG is completely safe for infants, children and adults of all ages, with no radiation and no side effects, and can be repeated whenever needed.

Question 6

How long does it take to get the results of an EEG?

Accepted Answer

Your neurologist reviews the recording carefully and usually shares the report shortly after the test, along with any next steps.
