Electroencephalography (EEG)
An EEG records brain activity and can help us decide if there is a problem or any disorders affecting the brain.
When do you need the test?
Your treating doctor may ask you to do the test, if you have any of the following conditions:
- Abnormal movements or seizures
- Brain tumors
- Sleeping disturbances
- Disturbance in conscious level
- Brain inflammatory conditions
- Brain stroke
Preparing for the EEG
- On the morning of the test, wash your hair.
- Do not use gel, mousse, hair cream or hairspray.
- You can eat as usual.
- You should not have anything with caffeine in it (like Coke, Pepsi, coffee, tea, or energy drinks).
- Inform the doctor about your prescribed medications.
What to expect
- EEG test measures brain activity by attaching small metal sensors (electrodes) to your scalp. The electrodes send brain signals to a recording machine to record graphs of brain activity that will be interpreted by the doctor.
Test Duration
The procedure takes about 30-60 minutes.
