If you have epilepsy and/or experience frequent seizures, a stay in an epilepsy monitoring unit (EMU) can help your care team assess your condition more effectively.
Neurologists and epileptologists refer patients to the EMU for evaluation. During their stay, patients are monitored 24/7 by specially trained staff who gather information about their seizures, what's causing them, and their severity. EEG and video technology collects data before, during, and after seizures.
EMU testing can help provide a more thorough assessment of your condition and help us develop an individualized treatment plan.
The UPMC Comprehensive Epilepsy Center is a national leader in treating epilepsy. Our epilepsy monitoring units use industry-leading technology and are staffed 24/7 by teams specially trained in epilepsy care.
An epilepsy monitoring unit (EMU) is a specialized unit that evaluates patients' epilepsy and seizures. Patients stay there as seizures might be provoked as needed by tapering medications and using various triggers.
The goal is to collect information about which area of a patient's brain is causing seizures and how severe their condition is. That enables us to recommend future treatments, such as new medications or surgery.
The epilepsy monitoring unit can:
Patients must be referred to the epilepsy monitoring unit by their neurologist or epileptologist — an epilepsy specialist.
Epilepsy monitoring is the gold standard for classifying epilepsy and seizure events. It can help provide your care team with answers about your epilepsy. It can also help your team create or adjust your treatment plan.
Eligible patients for epilepsy monitoring may include those with:
The epilepsy monitoring unit may use various tests and procedures to:
The primary diagnostic test in the EMU is a video electroencephalogram (VEEG). The EMU team attaches electrodes to patients' scalps to monitor their brains' electrical activity. The VEEG also records high-definition video of the patients to observe the physical effects of a seizure.
Combining brain and video monitoring provides the most complete picture of a seizure's neurological and physical manifestations. The VEEG captures data before, during, and after the seizure. It also has night vision capabilities, allowing video to be recorded in low-light conditions.
Other diagnostic testing that can take place in an EMU include:
While in the EMU, the team may taper patients' existing medications and use other triggers to provoke seizures. They also may start patients on new medications to see whether the drugs can better control their epilepsy.
Patients are referred to the epilepsy monitoring unit by a neurologist or epileptologist. Before going to the EMU, you will receive information about what to expect during your visit. You also can talk to the EMU team to tell them your health history and ask questions about your EMU stay.
An average stay in the EMU is three to five days, but it could be shorter or longer, depending on your specific case. With that in mind, it's important to pack essentials and comfort items for your stay. Consider bringing:
Also, you should arrange transportation to the hospital on the day of your admission and home from the hospital after your discharge.
Ask your care team if you should take your epilepsy and other medications as usual on the day of your EMU admission.
After the admission process, a member of the EMU team will take you to your room. Each EMU patient will have a private room and bathroom during their stay.
While in the EMU, nurses and other staff will be available at all times to help you with your needs. You should not do anything — even go to the bathroom — while unattended because of the risk of seizure. You will have a call button to ask for assistance.
To begin the monitoring process, the EMU team will attach electrodes to your scalp. This allows the team to monitor your brain's electrical activity with EEG. They will take a baseline measurement of your brain activity early in your stay.
During your stay in the EMU, the team will taper off your medications in an attempt to make a seizure more likely.
They may also try other seizure-provoking techniques, such as:
EMU nurses and other staff are specially trained to respond when seizures occur. Patient safety is the top priority during your stay. Other safety protocols include safety rails and padding on patient beds.
While in the EMU, you may wish to read, watch television or movies, work, and more. This can help make the stay easier. You also are permitted to have visitors.
The average stay in the EMU lasts three to five days. However, depending on your specific case, it may be shorter or longer.
Before your discharge, the EMU team will reintroduce your antiseizure medications. During your stay, they may also introduce new medications to help control your seizures.
It's ideal to have someone stay with you for a few days to assist with your recovery after your EMU stay. Ask your care team which activities to limit once you're back home and when it is safe to return to your normal routine.
You will have a follow-up appointment with your neurologist shortly after your EMU stay. You can go over your EMU results, review your medications, and discuss the next steps in your treatment.
