An EEG test in Delhi is a painless test that records the electrical activity of the brain to help diagnose seizures, epilepsy and other neurological conditions. Short for electroencephalography, it picks up the brain’s tiny electrical signals through small sensors placed on the scalp — with no needles and no radiation. At Edge Imaging & Diagnostics in Delhi, the EEG is performed with care and interpreted clearly to support your neurologist.
This guide explains what an EEG is, why it is done, how it is performed, and what to expect.

What Is an EEG?
An EEG records the patterns of electrical activity produced by the brain. Small metal sensors (electrodes) are placed on the scalp and connected to a machine that traces the brain waves. Certain conditions — most importantly epilepsy — produce characteristic changes in these waves, so an EEG is a key test for diagnosing and understanding seizures. It is completely safe and painless.
Why Is an EEG Done?
- To diagnose epilepsy and seizures, and to help identify the type
- To investigate episodes of blackout, fainting or unusual spells
- To assess unexplained confusion or altered awareness
- To evaluate certain sleep problems or recurring severe headaches, when advised
- To monitor a known seizure disorder or the effect of treatment
How the EEG Is Performed
A technician measures your scalp and gently attaches the electrodes using a paste. You rest quietly with your eyes open and closed, and may be asked to breathe deeply for a couple of minutes or look at a flashing light, as these can bring out abnormal activity. A routine EEG usually takes about 30–60 minutes. Sometimes a sleep or sleep-deprived EEG is advised, and you will be told how to prepare for that.
| EEG helps assess | Examples |
|---|---|
| Seizures / epilepsy | Diagnosis and seizure type |
| Blackouts & spells | Seizure vs other causes |
| Altered awareness | Encephalopathy and confusion |
| Treatment monitoring | Response in known epilepsy |
Is the EEG Safe and How Do I Prepare?
The EEG is completely safe and painless — it only listens to the brain’s own signals and gives no current or radiation. Come with clean, dry hair (no oil, gel or spray) so the electrodes attach well, take your usual medicines unless told otherwise, and follow any sleep instructions if a sleep-deprived EEG is planned. It is part of our neuro-diagnostic services, alongside NCV and BERA testing.
