What Is an EMU?
An EMU is a specialized inpatient unit that evaluates epilepsy and seizures. You will stay in the EMU for several days while your care team provokes seizures by tapering medications and using various triggers.
The goal is to monitor your seizure activity, collect information about which area of your brain is causing seizures, and learn about the severity of your condition in the safety of the EMU. This information enables your seizure care team to recommend future treatments, such as new medications or surgery.
The EMU can:
- Can help to characterize the episodes.
- Confirm an epilepsy diagnosis.
- Determine what type of seizures you have and which area of the brain is causing them.
- Determine if you are a candidate for surgery.
- Assess your response to medications and adjust medications as needed.
- Provide data for surgical planning.
Who’s Eligible for Epilepsy Monitoring Services?
You need a referral from your neurologist or epileptologist (epilepsy specialist) before admission to the EMU.
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:
- Epilepsy diagnoses — The EMU can help confirm or rule out a diagnosis of epilepsy.
- Frequent seizures — People who have frequent seizures at home may be referred to the EMU to adjust and optimize their medication in a safe environment.
- Functional neurological disorders — These disorders are conditions that can cause seizure-like responses, but they are not actually epileptic seizures. Some patients with these disorders may be misdiagnosed with epilepsy. The EMU can help provide the correct diagnosis and develop an appropriate treatment plan.
- Presurgical patients — The EMU can evaluate you to determine the source of your seizures and whether you are a candidate for surgery. The EMU can also map your brain to determine if the seizure onset zone can be safely removed.
- Refractory (drug-resistant) epilepsy — Refractory epilepsy occurs when a patient continues to have seizures despite trying two appropriately dosed medications. The EMU can help determine the next course of treatment.
What Epilepsy Monitoring Services Do We Offer?
The EMU may use various tests and procedures to:
- Confirm an epilepsy diagnosis.
- Diagnose the type of epilepsy.
- Identify the seizure onset zone.
- Prepare a treatment plan.
Diagnostic services and procedures
The primary diagnostic test in the EMU is a video electroencephalogram (vEEG). The EMU team attaches electrodes to your scalp to monitor your brain's electrical activity. The vEEG also records high-definition video 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 the EMU include:
- Intracranial EEG — Also known as stereoelectroencephalography (sEEG), this procedure involves placing electrodes into your brain to measure electrical activity. It can help identify the area of your brain where seizures start and determine whether it can be surgically removed.
Epilepsy treatment
While in the EMU, the team may taper your existing medications and use other triggers to provoke seizures. They may also start you on new medications to see whether the drugs can better control epilepsy.
What Can I Expect?
Preparing for your visit
You will be referred to the EMU by your neurologist or epileptologist.
Before going to the EMU, you will receive information about what to expect during your visit. You can also 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, though it may be shorter or longer depending on your needs. With that in mind, it's important to pack essentials and comfort items for your stay.
Consider bringing:
- A blanket, stuffed animal, or another small comfort item.
- Comfortable clothes/pajamas.
- Entertainment items, such as books, magazines, puzzles, a laptop, smartphone, tablet, and more.
- Snacks.
- Toiletries.
- Your current medications.
Also, you should arrange transportation to the hospital on the day of your admission and home from the hospital after your discharge.
During your EMU stay
You should take your epilepsy and other prescribed medications on the day of EMU admission unless otherwise directed by their health care provider.
Your EMU room
After the admission process, a member of the EMU team will take you to your room. You will have a private room furnished with a flat-screen television, Wi-Fi access, a sitting area, and a recliner for a family member or friend to visit with you. Your room also will have a private bathroom and shower.
While at 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.
The monitoring process
To begin the monitoring process, the EMU team will attach electrodes to your scalp. These electrodes will be connected to an EEG machine that collects information about your seizures. 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:
- Hyperventilation.
- Partial sleep deprivation.
- Photostimulation.
In addition, your activities are captured on film to provide your neurologists with a very clear picture of what happens when your symptoms are active. Neurologists review your recordings daily and discuss a plan of care with you and your family.
Your safety and comfort
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. These activities can help make your stay easier. You are also permitted to have visitors.
After your EMU stay
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.
When you're discharged, 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 after 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 after your EMU stay.
