Seizure Intervention Unit (SIU)
One of the best ways for your physician to understand your seizures is to observe them. At the same time, it’s essential to see what is happening with the brain’s electrical activity by doing an Electroencephalography (EEG).
What to expect
Once admitted, you will be shown to your private room. You will be informed of the procedure's risks and benefits before you consent to allow us to audio and video record your seizures.
The SIU staff will show you the monitoring equipment. For your privacy, you will be shown the areas in the room that are not monitored.
Electrodes, attached to wires, will be placed on your scalp with glue and will be in place for the duration of your stay (typically 7–10 days, but can go longer). The wires are plugged into equipment that you carry in a soft fabric envelope on your chest or around your waist. During a seizure, the equipment must move with you. You will be able to move to the bathroom or the recording room. The electrodes will be removed for showers/shampooing as required every 4–5 days.
Once everything is in place, you are to remain in bed except when you get up to use the bathroom. This is for your safety and to ensure that your seizures are captured on video.

Your participation
Your participation in helping characterize your seizures will also be required. This will allow us to find the seizure on the recordings. Sometimes, your physician may request that someone stay with you during your admission. A cot is available if needed.
The nurse will encourage you to talk and follow instructions during your seizure. Your ability to talk, follow simple instructions, and identify objects provides the medical team with information about your seizures.
Reducing anti-seizure medication is necessary for some patients to allow for seizure activity. Your doctor will discuss this with you. If necessary, you will also have an intravenous saline lock in your arm for medication.
