The Comprehensive Epilepsy Center at the University of Chicago Medicine is at the forefront of epilepsy care. Many of our patients come to us after trying a number of different medications and therapies with little success. Backed by the development of groundbreaking diagnostic techniques and a long history of research, our expert team has the experience to manage nearly all epilepsy-related problems from new onset seizures to rare and difficult-to-treat epileptic syndromes. With non-invasive technology and contemporary diagnostic techniques, we can pinpoint the origin of most seizures with precision. Having this advantage can significantly increase diagnostic accuracy and improve patient outcomes.
Epilepsy is a chronic, non-communicable neurologic disorder defined by two or more unprovoked seizures. Provoked seizures result from some immediately recognizable stimulus (for example, low blood sugar in people with diabetes), while unprovoked seizures have no immediately recognizable cause. Provoked seizures are unlikely to recur if the provocations can be avoided; however, unprovoked seizures have the tendency to recur and are the hallmark of epilepsy. When someone has two or more seizures, doctors diagnose epilepsy.
There are many types of epilepsy. Some types of epilepsy and epilepsy syndromes include:
A seizure is a sudden surge of abnormal electrical activity in the brain. Electrical activity in the brain is normal. It’s how our brain works. Seizures occur when there is significant disruption of that normal electrical activity in the brain. The general symptoms of seizures may include changes in consciousness, sensation, movement or behavior.
No. Not all seizures are caused by epilepsy. Approximately 10 percent of the general population may experience a seizure during their lifetime, but only 1 percent of the population has epilepsy. A single seizure may or may not progress to a chronic and recurrent condition or epilepsy.
Although there are many types of seizures, those that people with epilepsy experience commonly fall into generalized and partial (or focal) seizures.
Generalized seizures are characterized by widespread electrical discharges in both sides of the brain. You might think of it as a lightning storm in which the lightning seems to be coming from all areas of the sky at the same time.
There are six types of generalized seizures:
Partial seizures, also known as focal seizures, begin in one side of the brain. They fall into one of two groups:
For some types of seizures, an aura happens before a seizure and may alert a person that a seizure may occur. Auras typically begin seconds before the seizure.
The symptoms that accompany an aura can vary depending on the type of seizure and the area of the brain affected. Some symptoms of aura include:
Perceived sounds, tastes, or smells (some people report smelling burning rubber, for example)
Physical sensations, like dizziness, headache, numbness, and lightheadedness
At UChicago Medicine, we offer an advanced treatment designed to prevent seizures before they start and often before a patient feels the aura. The NeuroPace Responsive Neurostimulation System (RNS) is a tiny device that detects abnormal brain activity and responds in real time to deliver short bursts of electrical stimulation designed to reduce how often seizures happen.
Similarly, deep brain stimulation (DBS) prevents seizures to spread throughout the brain and stops them from becoming clinically relevant. Neuromodulation is just one of the several treatment options we provide, from the latest anti-epileptic drugs to Visualase MRI-guided laser thermal ablation.
Ictus is another word for the seizure itself — the part of the seizure that outsiders can witness. It can be convulsive, commonly called “grand mal,” or non-convulsive, such as staring and inability to respond normally.
The postictal stage occurs after the ictus or active stage of the seizure. During the postictal stage, the body begins to relax and aftereffects may set in. The type and length of aftereffects will vary from person to person and may include:
We have a multidisciplinary team of experts, which includes adult and pediatric specialists who are board-certified and fellowship-trained in epilepsy, neurology, neurophysiology, neurosurgery, neuropsychology, neuropsychiatry and neuroradiology. Our physicians collaborate to provide the most effective, individualized care to each and every one of our patients.
Our unique, comprehensive approach leads to better results. The specialists at the UChicago Medicine Epilepsy Center understand epilepsy because we see it and treat it every day. Our technology and depth of knowledge help us accurately diagnose epilepsy, which can lead to better treatment plans and better results for our patients.
We use sophisticated, computer-based functional imaging techniques — pioneered here — to provide a detailed 3D model of epileptic electrical activity inside the brain. This technology, coupled with our other diagnostic capabilities, makes our ability to localize seizure truly exceptional.
We provide advanced treatment options not widely available, such as the NeuroPace Responsive Neurostimulation System (RNS). The NeuroPace device continuously monitors brainwaves to detect abnormal activity and responds with electrical stimulation to prevent a seizure — often before symptoms occur. UChicago Medicine neurosurgeons also offer Visualase, a leading-edge surgical laser ablation treatment that destroys seizure-causing tissue with targeted accuracy under real-time MRI monitoring. Both of these treatment options offer relief for patients with drug-resistant epilepsy. Deep brain stimulation is available and FDA-approved for the treatment of medication resistant epilepsy. UChicago Medicine is one of the largest national DBS centers.
We’re recognized as one of the best. We have two nationally classified Level 4 epilepsy centers — one for adults and one for children. That is the highest possible classification granted by the National Association of Epilepsy Centers.
We offer continuous care throughout the patient’s lifespan. Doctors at the adult and pediatric epilepsy centers, combined into one comprehensive epilepsy center program, work together every day to make sure patients receive seamless care when they transition from childhood to adult care.
