EEG Test in New Delhi

A painless brain-wave test that helps diagnose epilepsy and evaluate unexplained spells.

What we offer

  • 30–60 minute recording of brain electrical activity
  • Helps diagnose epilepsy and classify seizure type
  • Useful for unexplained blackout spells and sleep disorders
  • Sleep-deprived EEG improves yield when routine EEG is normal
  • Results interpreted by a qualified neurologist

An EEG (electroencephalogram) records the electrical activity of your brain through small electrodes placed on the scalp. It is painless, non-invasive and involves no radiation. The test is central to diagnosing epilepsy, classifying seizure types, and evaluating unexplained episodes of loss of awareness.

During the test you may be asked to breathe deeply, look at a flashing light, or sleep — these activation procedures increase the chance of capturing abnormal patterns. A normal EEG does not rule out epilepsy if your clinical history is strongly suggestive; sometimes a repeat or sleep-deprived EEG is needed.

Patients in New Delhi are commonly referred for EEG after a first seizure, when medication is not controlling seizures, or when spells might represent syncope, panic attacks or sleep disorders rather than epilepsy. Accurate interpretation requires a neurologist who correlates the tracing with your history.

Dr. Sudheer Pandey orders and interprets EEG in the context of your full neurological assessment, ensuring results lead to a clear diagnosis and treatment plan rather than standing alone as an isolated report.

Frequently Asked Questions

Direct answers to common questions — when to seek care, what to expect, and what to do next.

Wash your hair the night before — no oil, gel or conditioner. Eat normally, take your usual medications unless your doctor says otherwise, and arrive with clean, dry hair.

No — an EEG is completely painless. You will feel slight pressure when electrodes are applied to your scalp, but there are no needles and no electrical shocks delivered to you.

A routine EEG takes 30–45 minutes. A sleep-deprived EEG may take up to 90 minutes. Plan to be at the clinic for at least 1 hour including setup.

Yes — eat and drink normally before a routine EEG. For sleep-deprived EEG, follow your clinic's instructions on how much sleep to skip the night before.

No — up to half of epilepsy patients have a normal routine EEG. If your doctor strongly suspects epilepsy, a sleep-deprived or prolonged EEG may still be needed.

Your neurologist will order a sleep-deprived EEG if your routine EEG was normal but seizures continue. Staying awake from midnight until the test increases the chance of detecting abnormalities.

Preliminary findings are often discussed the same day. A full written report is usually available within 2–5 working days.

Do not stop medication on your own. Your neurologist will tell you if a brief reduction is needed for a specific test — stopping suddenly can trigger seizures.
