Video EEG may be used when the diagnostic question requires event-EEG correlation, such as unclear episodes or seizures that continue despite treatment. The choice depends on the history, examination and prior findings.
When might Video EEG be considered? It may help when routine EEG is normal or inconclusive, seizure type is unclear, blackouts need clarification, PNES is suspected, or drug-resistant epilepsy needs further evaluation.
At Gujarat Epilepsy Clinic, Dr. Abhishek Gohel and Dr. Rutul Shah use video EEG as a core tool for epilepsy diagnosis, seizure classification, and epilepsy surgery evaluation in Ahmedabad.
📍 Two Locations, Flexible Options
At our clinic: Shorter planned recordings and selected extended monitoring, when appropriate
At KD Hospital: Longer monitoring may be planned when the clinical question or safety needs require it
What is Video EEG?
Video EEG combines continuous brain-wave recording (EEG) with synchronized video. Monitoring duration varies according to the clinical question, event frequency and safety needs.
Why the difference matters:
A routine EEG captures a short snapshot. Because seizures may not occur during that time, some people with epilepsy have a normal routine EEG. Longer Video EEG monitoring can increase the chance of recording a typical event; when one is captured, clinicians interpret the video and EEG together with the history and other findings.
Outstation Video EEG planning
Patients travelling to Ahmedabad should usually bring previous EEG reports, MRI reports or discs, prescriptions, discharge summaries and phone videos of events. Video EEG is planned when event capture, PNES assessment, seizure classification, drug-resistant epilepsy review or surgery evaluation needs more detail.
Why is Video EEG Done?
1. Seizure Classification
Not all seizures are the same. Focal seizures start in one part of the brain, while generalized seizures involve networks on both sides. When a typical event is captured, Video EEG can help clinicians assess seizure onset and spread.
2. Pre-Surgical Evaluation
For selected patients considering epilepsy surgery, Video EEG may be part of the evaluation and can help assess the seizure-onset zone alongside other findings.
3. Differentiating Epilepsy from PNES
Psychogenic non-epileptic seizures (PNES) can resemble epileptic seizures. Clinical assessment and review of typical events are important; Video EEG may be used when appropriate to help distinguish non-epileptic from epileptic events.
4. Drug-Resistant Epilepsy Evaluation
When seizures continue despite trying two or more medications, video EEG helps determine if surgery or other advanced treatments might help.
Who Needs Video EEG?
- Seizures continue despite medication. You've tried at least two anti-seizure medications, but seizures persist.
- The seizure type is unclear. Your episodes have unusual features, or doctors aren't certain they're epileptic seizures.
- You're considering epilepsy surgery. Video EEG may be part of a pre-surgical evaluation when appropriate.
- PNES is suspected. Episodes look like seizures but might have a psychological basis.
- Routine EEG was inconclusive. A normal routine EEG doesn't rule out epilepsy.
Video EEG is especially useful when the next decision is bigger than one routine report: whether to add more medicines, correct a non-epileptic diagnosis, investigate syncope-like blackouts, or move a focal epilepsy case toward pre-surgical evaluation.
Who Should Be Referred for Video EEG?
- Patients with unexplained blackouts where it is unclear whether the episodes are seizures, syncope, or non-epileptic events
- People with repeated seizures despite treatment who may have drug-resistant epilepsy
- Patients with suspected PNES or events that do not fit a typical seizure pattern
- Children or adults with unclear seizure classification after routine EEG and MRI review
- Patients being considered for surgery who need localization of seizure onset before advanced treatment decisions
When Video EEG is the right next step
Many patients are sent for repeated routine EEGs even when the real question has moved beyond a short test. Video EEG becomes the right next step when the decision depends on capturing the actual event, not just looking at a background recording.
- Routine EEG was normal but the suspicion remains high. A normal routine EEG does not rule out epilepsy.
- The episodes are still poorly classified. Treatment should not drift forward on guesswork alone.
- Blackouts or shaking episodes may not be epileptic. Video correlation matters here.
- Seizures continue despite treatment. This may indicate drug-resistant epilepsy or the need to revisit the diagnosis.
- A surgery decision is being considered. At that point, precise seizure localization becomes much more important.
How doctors decide clinic versus KD Hospital Video EEG
Not every patient needs the same monitoring setup. The choice depends on how often events happen, how dangerous they are, and what question needs answering.
Useful for shorter recordings, frequent events, and selected diagnostic clarifications.
Better for longer monitoring, medication reduction, difficult cases, and surgery workup.
Event frequency, safety risk, need for prolonged capture, and how much supervision the case needs.
The goal is not to do the biggest test by default. It is to choose the shortest test that can still answer the right question safely.
The Video EEG Procedure
Electrode Placement
A technician places 21 electrodes on your scalp using a special paste. This is painless — the electrodes only record electrical activity; they don't send any electricity into your brain.
Monitoring Period
The monitoring duration is planned around the clinical question, event frequency and safety needs. Your team will explain what to expect, including family arrangements where available.
Medication Adjustment
In some cases, your doctor may reduce medications to increase the chance of recording a seizure. This is done carefully under medical supervision.
How to Prepare for Video EEG
- Wash your hair the night before. Don't use conditioner, gel, or oil.
- Continue your medications unless your doctor instructs otherwise.
- Avoid caffeine for 24 hours before the test.
- Bring: Comfortable clothes, entertainment, toiletries, medication list, previous reports.
Where Is Video EEG Done?
🏥 At Our Clinic — Short-Term Video EEG
- Shorter recordings: Used for selected diagnostic questions
- Extended monitoring: Considered when more event capture is needed
Suitable for patients with frequent seizures, shorter diagnostic recordings, initial evaluation, and selected follow-up recordings.
🏨 At KD Hospital — Long-Term Video EEG
- Longer monitoring when the clinical question or safety needs require it
- Epileptologist-supervised by Dr. Abhishek Gohel and Dr. Rutul Shah
- Continuous monitoring support
- Private rooms with space for family
What Happens After Video EEG?
After monitoring ends, the recorded data requires detailed analysis, not a quick glance. The result should lead to a clearer next step, not another vague label.
- Findings support an epilepsy diagnosis or clarify seizure type. Medicine review or surgery evaluation may be discussed.
- Findings raise a non-epileptic-event question. Further clinical assessment and psychological support may be discussed.
- More information needed. Additional testing may be required.
- Further surgery evaluation may be appropriate. The team can discuss next steps.
What this may help clarify: whether medicine review, a revised diagnosis or surgery evaluation should be discussed. Decisions depend on the complete clinical picture.
Frequently Asked Questions
No. Electrode placement involves paste applied to the scalp — no needles, no pain. The electrodes only record; they don't transmit any electricity.
Monitoring duration is planned around the clinical question, event frequency and safety needs. Your team will explain the expected stay before admission.
Yes. One family member can stay in the room with you throughout the monitoring period.
Not everyone has a seizure during monitoring. However, the prolonged recording time and sometimes medication reduction increase the chances of capturing one.
Yes. It's a non-invasive, observational test. The main risk is seizure occurrence, which is why you're monitored continuously by trained staff.
Ambulatory EEG records brain waves at home but without video. Video EEG adds video correlation and supervised monitoring, which may be useful when the clinical question needs that information.
Doctors order video EEG when routine EEG is inconclusive, when seizure type is unclear, when blackouts need further evaluation, when PNES is suspected, or when drug-resistant epilepsy and surgery evaluation are being considered.
Yes. Video EEG is especially useful when episodes are difficult to classify. It helps differentiate epileptic seizures from fainting, psychogenic non-epileptic seizures, and other events by matching behavior on video with brain-wave recording.
