Video EEG monitoring

Overview

Video EEG monitoring is a test that records your brain's electrical activity and video of your behavior at the same time. It helps doctors see what happens during a seizure or unusual episode.

Video EEG monitoring is a standard test for people with epilepsy that is hard to diagnose or treat. It is not a routine test for everyone, but it is performed in many hospitals worldwide.

It is typically used for people of any age who have seizures or seizure-like episodes that are difficult to identify or control.

Symptoms

Common symptoms

• Seizures that do not stop quickly or happen in clusters
• Unusual movements or behaviors that may be seizures
• Sudden confusion or memory loss
• Staring spells or loss of awareness
• Sudden falls without clear reason

Symptoms in children

• The same types of seizures as adults, plus infantile spasms or febrile seizures
• Frequent staring spells that affect learning
• Sudden stops in breathing or turning blue (with some seizure types)

Symptoms in older adults

• Confusion or memory problems that could be seizures
• Unexplained falls or fainting
• Sudden changes in behavior or speech

Causes

Main causes

• Video EEG monitoring is not caused by a condition; it is used to find the cause of episodes that may be seizures.
• Possible underlying causes of seizures include epilepsy, head injury, brain infection, stroke, or metabolic disorders.

Risk factors

• Having epilepsy that does not respond well to medication
• Unclear diagnosis after standard tests (EEG, MRI)
• Episodes that might be psychogenic nonepileptic seizures (PNES)

When to see a doctor

See a doctor urgently if:

• Call your local emergency number if a seizure lasts more than 5 minutes or if someone has multiple seizures without waking up.
• Seek immediate care for a first seizure or if a seizure causes a serious injury.

Book a routine appointment if:

• Make an appointment with a neurologist (a nerve and brain doctor) if you have had any new seizures or unusual episodes.
• If you are already diagnosed with epilepsy and your seizures change, talk to your neurologist about whether video EEG monitoring might help.

Diagnosis

Video EEG monitoring is a test, not a diagnosis. It records brain activity and video to help your doctor diagnose the type of seizure or rule out other conditions.

Tests that may be done

• Continuous EEG recording with electrodes on your scalp
• Time-synced video recording in a special hospital room
• Sometimes blood tests or brain scans (MRI) are done before or after to support the diagnosis

What to expect at your appointment

You will stay in a private hospital room. Small electrodes are attached to your scalp with paste. A camera records your movements. You can move around, read, or sleep. The test may last 1 to 7 days. Staff will be nearby to help you. You may have some seizures, which is part of the test. Afterward, the electrodes are removed easily.

Treatment

Treatment depends on what the video EEG finds. If epilepsy is confirmed, medications can help control seizures. If the episodes are not seizures, other treatments may be needed.

Self-care at home

• Keep a diary of episodes to share with your doctor
• Follow safety measures like not driving until cleared by a doctor
• Get enough sleep and avoid triggers like flashing lights (if photosensitive epilepsy is suspected)

Medical treatments

If epilepsy is diagnosed, doctors may prescribe anti-seizure medications. The specific medicine depends on your seizure type, age, and other factors. Always take medications exactly as prescribed and talk to your doctor before making changes.

When is surgery considered?

If video EEG shows that seizures start from a small area of the brain that can be safely removed, brain surgery may be considered. This is only done after careful evaluation by a specialist team.

Living with this condition

If you are diagnosed with epilepsy, you can live a full life. Learn your seizure type, take medications regularly, and avoid known triggers. Inform family, friends, and coworkers about basic seizure first aid.

Lifestyle tips

• Maintain a regular sleep schedule
• Manage stress with relaxation techniques
• Avoid alcohol or recreational drugs that can lower seizure threshold
• Wear a medical alert bracelet if seizures are not well controlled

Diet and exercise

A balanced diet is important. For some types of epilepsy, a special high-fat, low-carbohydrate diet (ketogenic diet) may help. Exercise is safe for most people with epilepsy; always check with your doctor first.

Mental health and emotional wellbeing

Living with seizures can cause anxiety, depression, or social isolation. It is normal to feel worried. Talk to your healthcare provider about mental health support. You are not alone.

Prevention

Epilepsy itself often cannot be prevented, but you can reduce the number of seizures by taking your medication as prescribed and avoiding triggers that affect you.

Complications

If left untreated

• Injury from falls during a seizure
• Status epilepticus (prolonged seizures that can be life-threatening)
• Memory problems or learning difficulties over time
• Social withdrawal and depression

Long-term outlook

With the right diagnosis and treatment, most people with epilepsy can reduce their seizures and live active lives. Many children outgrow epilepsy. Even for those who need lifelong treatment, modern medicines and support make a huge difference.
