EEG in Delhi

Electroencephalogram (EEG) at Classic Diagnostics — non-invasive recording of brain electrical activity to evaluate seizures, sleep disorders and neurological complaints.

What is an EEG?

An EEG records electrical activity of the brain using small electrodes placed on the scalp. It is the primary diagnostic test for epilepsy, seizures, encephalopathy, and many sleep and consciousness disorders. The standard recording lasts 20–40 minutes and is completely painless.

When is an EEG recommended?

Suspected epilepsy or unexplained seizures · loss of consciousness · recurrent headaches · evaluation of brain function after head injury · sleep disorders · suspected encephalitis or encephalopathy · pre-surgical assessment for neurological surgery · monitoring of dementia or developmental delay.

Preparation & what to expect

Wash your hair the night before (no oil/conditioner/spray on the day). Sleep less than usual if a sleep-deprived EEG is requested. Avoid caffeine on the day. During the test, you lie quietly while light flashes and breathing exercises are performed. Sedation is rarely needed.

Frequently Asked Questions about EEG

Is an EEG painful?

No — electrodes are simply placed on the scalp using a paste. No needles, no current, no pain.

How long does an EEG take?

A routine EEG takes 30–60 minutes including setup. Long-duration and sleep EEGs may take 2–4 hours.

Will an EEG diagnose epilepsy on its own?

Usually yes if abnormal activity is captured. A normal EEG does not rule out epilepsy — your neurologist may recommend a sleep-deprived or long-duration EEG.

Can I take my medications before an EEG?

Yes — continue all medications unless your neurologist specifically advises otherwise.
