EEG Test in Gurugram

Understanding EEG

EEG stands for electroencephalogram. It is a non-invasive test that records electrical activity from the brain using small electrodes placed on the scalp.

EEG is commonly used when a doctor is evaluating seizures, fits, staring spells, blackouts, sudden confusion, jerks, abnormal movements, altered awareness, or certain unexplained episodes.

At JHN, EEG is interpreted in a clinical context. The test is most useful when it is matched to the patient’s actual event history.

Quick Check: When Might EEG Be Needed?

A doctor may advise an EEG for:

• First seizure-like event
• Recurrent fits
• Staring spells
• Sudden confusion episodes
• Jerks or myoclonic movements
• Blackouts where seizure is possible
• Episodes during sleep
• Epilepsy follow-up in selected cases
• Differentiating epileptic from non-epileptic events when combined with history and video EEG
• Certain unexplained neurological episodes

Key Point

A normal EEG does not always rule out epilepsy. EEG is useful, but diagnosis depends on the event history, witness description, clinical examination, EEG findings, and sometimes imaging or other tests.

Types of EEG

Routine EEG

A standard EEG recording is used for seizure and spell evaluation.

Sleep-Deprived EEG

A study was performed after reduced sleep. Sleep deprivation can sometimes increase the chance of recording seizure-related activity.

Short Video EEG

EEG with video recording for selected events or diagnostic clarification.

Longer Video EEG Monitoring

Used for difficult-to-capture events, recurrent unexplained spells, suspected PNES/FND, or complex seizure evaluation when clinically appropriate.

What EEG Can Show

EEG may show:

• Normal brain-wave background
• Epileptiform discharges, which are patterns that may support seizure tendency
• Focal slowing, which may suggest dysfunction in one brain region
• Generalized slowing in selected conditions
• EEG changes during a captured event if video EEG is performed

Epileptiform does not automatically mean the patient has epilepsy. The result must match the clinical story.

What to Expect at Your First Visit

Before the EEG, we review why the test is needed. We ask about the event, triggers, duration, recovery, witness description, medications, sleep deprivation, alcohol, prior reports, and any neurological symptoms.

If EEG is appropriate, we select the type of EEG based on the clinical question.

How to Prepare for an EEG

Unless told otherwise:

• Wash your hair before the test
• Avoid oil, gel, or heavy hair products
• Bring previous EEG, MRI, prescriptions, and reports if available
• Bring a witness or phone video if available
• Follow clinic instructions if a sleep-deprivation EEG is advised
• Do not stop seizure medicines unless the doctor specifically tells you to

What Happens During an EEG?

Small electrodes are placed on the scalp. The recording is painless and non-invasive. You may be asked to open and close your eyes, breathe deeply, or look at flashing lights if appropriate.

Some patients may be asked to try to sleep during the recording.

When EEG May Not Be Enough

EEG may be normal between seizures. If events are infrequent or unclear, a longer EEG or video EEG may be needed. Some events are not epileptic and may require heart evaluation, sleep evaluation, psychological support, or other medical review.

Patient-Friendly Summary

EEG is a useful brain-wave test, but it is not a stand-alone diagnosis. It works best when combined with a careful neurological evaluation and event history.
