RECOVERY BY DESIGN
“I went into it with an open mind and really wanting to get answers,” she says. “The nurses were really supportive and did a great job of helping me feel comfortable and safe.” When a patient enters the Scripps EMU, the goal is to create an environment that will allow their seizures to emerge naturally. This involves tapering them off any anti-seizure medications, depriving them of sleep by allowing only a few hours of sleep per night and, in some cases, using visual stimulation or hyperventilation to encourage seizures. All of this occurs in a highly controlled medical environment, with nurses trained to respond quickly and provide seizure first aid if needed. Collopy’s first two nights in the unit were uneventful. Then, on the third night, she had two seizures consistent with what had been happening at home. Finally, Dr. Van Noord was able to confirm that Collopy’s seizures were in fact caused by a common form of epilepsy called focal epilepsy—but it wasn’t typical. “Epilepsy is a medical condition that causes a temporary, uncontrolled surge of electrical activity in your brain. Think of it as a spontaneous electrical storm in the brain,” says Dr. Van Noord. “In focal epilepsy, the surge starts in one part of the brain and can spread from there.” Focal seizures most commonly start in the brain’s temporal lobe, but the seizures Collopy had been having for months didn’t sound typical of temporal lobe epilepsy. The EMU study revealed that Collopy’s seizures were likely starting in her frontal lobe— information that was key in helping Dr. Van Noord determine treatment.
and how best to control them. Unfortunately, her condition was refractory to medication, meaning her seizures were not adequately controlled by treatment. “About 50% of people with epilepsy get their seizures under control with one medication at a reasonable dose. If they’re still having seizures, typically we’ll add a second medication,” explains Dr. Van Noord. “We can get about 70% of people seizure-free on two medications, but that means about 30% are still refractory. While we can keep trying additional medications, at that point it starts to feel like guesswork.” By December of 2021, Collopy was taking several medications and still having nightly episodes. REAL-TIME SEIZURE MONITORING IN THE EMU Dr. Van Noord decided to have Collopy evaluated in the Scripps Memorial Hospital La Jolla Epilepsy Monitoring Unit (EMU).
The inpatient unit continuously monitors patients with epilepsy and other seizure disorders for up to five days using continuous video surveillance and
STRUGGLING TO FIND ANSWERS Despite the medication, Collopy’s seizures returned. Though she didn’t have another tonic-clonic episode, the multiple small seizures that occurred several nights a week left her exhausted. She slept during the day and had no energy. Even basic daily activities were a struggle. Her seizures also forced Collopy to give up her driver’s license. Having returned home to San Diego in 2020 after a career in New York’s fast-paced fashion industry, Collopy had recently launched an interior design company. Being unable to drive to clients’ homes severely impacted her business and her everyday life. A family friend referred Collopy to Scripps Clinic neurologist Michelle Van Noord, MD, who specializes in epilepsy. During the next few months, Collopy underwent a barrage of tests and tried multiple medications as her team worked to determine what was causing her seizures
electroencephalogram (EEG) monitoring, with the goal of capturing the exact moment a patient has a seizure. “The EMU is the gold standard for diagnosis when someone comes to us and they’re having seizures or seizure-like events and not responding to medication,” says Dr. Van Noord. “Typically, patients don’t have seizures in front of us in the office, so we’re making decisions about management based on reports from the patient and people who see what happens at home. The EMU allows us to actually capture their events with EEG and video to see exactly what is happening during the seizure, as well as record the brain activity.” The video and EEG data provide important information that helps physicians confirm that a patient’s seizures are caused by epilepsy and not something with similar symptoms, such as syncope (passing out) or other seizure mimics. “When we do confirm a patient has epilepsy, the EMU also allows us to figure out what type of seizure they’re having, and where in the brain it is coming from,” adds Dr. Van Noord. “We do this by studying both what the patient does during the seizure and the recording from the surface electrodes attached to their scalp.” Collopy, who had never spent a night in a hospital before the ED, began her stay in the EMU in January 2022. With COVID-19 restrictions still in place, visitation was limited. She was a bit nervous about being alone in the unit, but also hopeful.
