EEG Test (Routine and Sleep-Deprived EEG)
A painless test that records the brain’s electrical activity to assess seizures, blackouts and changes in awareness.
At New City Clinic, EEG Test is performed in Istanbul by specialist physicians at partner hospitals licensed by the Turkish Ministry of Health.
EEG Test in Istanbul: overview
An EEG (electroencephalogram) records the brain’s electrical activity through small electrodes placed on the scalp. No needles are used, it is painless and no electricity is given; only the brain’s own signals are recorded. A routine EEG takes about 30–45 minutes, during which you are asked to open and close your eyes, breathe deeply and look at a flashing light. Where needed, a sleep-deprived EEG is performed to increase the chance of recording seizure activity. The recording is made by an electroneurophysiology technician and reviewed and reported by a neurologist.
Who is it for?
An EEG suits people who have had a seizure, fainting or blackout, unexplained episodes of confusion or staring, and people with epilepsy whose treatment is being reviewed.

What you should know
- Most tests are painless; needle EMG can cause brief mild discomfort
- You may feel tired after a sleep-deprived EEG; do not drive that day
- In an emergency such as sudden weakness, slurred speech or a seizure, go to your nearest emergency department
Every medical procedure carries risk. Your physician will explain the risks specific to you during your examination.

How should I prepare for the tests?
For an EEG, your hair should be clean and free of oil; before an EMG, do not apply cream to your arms and legs. Do not stop your medicines – bring a list with you. Any special preparation is sent to you in writing beforehand.
Who reviews the results?
Recordings are made by an electroneurophysiology technician; they are reviewed and reported by a neurologist.
How is the price determined?
It depends on the consultations and tests needed. After your reports have been reviewed, you receive a free, itemised written quote.
How long does it take?
A routine EEG takes about 30–45 minutes including preparation; a sleep-deprived EEG takes longer.
Can EEG prove that I do not have epilepsy?
No. A normal EEG does not rule it out, which is why the neurologist assesses the EEG together with your history and examination.
