Long-Term Video EEG Monitoring
What is it?
Long-term video EEG monitoring refers to the simultaneous recording of EEG and clinical behavior over extended periods of time to evaluate patients with paroxysmal disturbances of cerebral function. Long-term video EEG monitoring is used when it is important to correlate clinical behavior with EEG phenomena.
How long does it take?
This test requires an admission to the hospital with an average stay of 3 to 5 days.
Why is this test performed?
To diagnose episodic events (those which happen from time to time). These events may be, but are not limited to:
- Epileptic seizures
- Fainting or black-out spells
- Spells of unknown origin
- Hallucinations or behavior problems
- Withdraw or change in medications
What should you do to prepare for the test?
Wash your hair. Do NOT use any sprays, oils, or dressings of any kind. Continue taking prescribed medicine unless your doctor gives other instructions. Bring a complete list of all your medications and dosages with you. Hospital gowns are usually available for your use. You may bring a one-week supply of button-down shirts, sweat pants and/or shorts and underclothing.
It is encouraged you bring things-to-do items, such as:
- Reading materials
- Each room has a TV and internet service available
- You will NOT be able to shower or wash your hair while your monitoring is being conducted. You will be able to sponge bathe daily.
How is it performed?
A china marker will be used to measure and mark the areas where electrodes will be glued to your scalp. Each electrode is checked with a meter to ensure proper functioning. You will now be monitored for the next 3 to 5 days. You may simulate your everyday life as much as possible, moving freely around your private room. A specially trained doctor will review your monitoring daily. Test results will be discussed with you daily.
After the test
The electrodes are removed with a special remover, which dissolves the glue and leaves your hair and skin intact. You may wash your hair once the wires are removed. A summary of your test results will be sent to your personal physician.
