Epilepsy & Seizures

Epilepsy is a neurological disorder characterized by a tendency to have recurrent, unprovoked seizures. A seizure is a sudden, abnormal burst of electrical activity in the brain that can affect awareness, movement, sensation, emotions, or behavior. Some individuals may experience a single seizure during their lifetime due to factors such as illness, medication effects, sleep deprivation, or other temporary conditions. A single seizure does not necessarily mean a person has epilepsy. However, recurrent unprovoked seizures often require further evaluation and may lead to a diagnosis of epilepsy, warranting long-term treatment and management.

Because seizure symptoms can vary widely, an accurate diagnosis is essential. Seizures can result from many different causes, and determining whether a person has epilepsy, if so, what type of epilepsy, and where in the brain the seizures are arising, often requires a detailed clinical evaluation. Diagnostic tools such as an electroencephalogram (EEG), along with brain imaging and a thorough medical history, help identify the type and cause of seizures and guide the most appropriate treatment plan.

You may benefit from specialty epilepsy care if seizures continue despite treatment, if episodes are difficult to diagnose, or if medication side effects are affecting your quality of life. A specialized evaluation can help confirm the diagnosis, identify the type of seizure disorder, and ensure you receive the most effective treatment plan.

Approximately one-third of people with epilepsy develop drug-resistant epilepsy (DRE), meaning seizures continue despite adequate trials of two appropriately chosen anti-seizure medications. For these patients, early referral to a comprehensive epilepsy center is important, as delayed evaluation may lead to ongoing seizure-related risks, injuries, reduced independence, and missed opportunities for potentially more effective treatments, including epilepsy surgery, neuromodulation, or dietary therapies.

Specialized epilepsy care is also important for women who are pregnant or planning pregnancy. Some anti-seizure medications may carry risks during pregnancy, and treatment plans often need to be individualized to optimize both seizure control and maternal and fetal health.

Diagnosing epilepsy begins with a detailed medical history, neurological examination, and diagnostic testing to determine whether a person's symptoms are caused by seizures and, if so, where in the brain they originate. An electroencephalogram (EEG) is commonly used to record the brain's electrical activity and identify patterns that may suggest epilepsy.

When routine testing does not provide a clear diagnosis, patients may undergo prolonged monitoring in an Epilepsy Monitoring Unit (EMU). Continuous video EEG monitoring allows specialists to record brain activity before, during, and after events, helping distinguish epileptic seizures from other conditions and better characterize seizure type and location.

Treatment depends on seizure type, how often seizures occur and whether they respond to medication. Many patients do well with medication adjustments, but others may need advanced therapies to reduce seizure burden and improve safety.

Options may include:

• Medication management to optimize seizure control while balancing side effects and long-term goals.
• Epilepsy monitoring and surgical workup for patients with drug-resistant epilepsy or unclear seizure localization.
• Neuromodulation such as VNS, DBS, or responsive neurostimulation (RNS) for selected patients
• Surgical options including resection, laser ablation and image-guided procedures when a seizure focus can be targeted safely

Uncontrolled seizures can affect far more than a patient's immediate symptoms. They may increase the risk of falls, injuries, motor vehicle accidents, driving restrictions, missed school or work, medication side effects, and a reduced sense of independence.

Over time, poorly controlled epilepsy can also affect memory, cognitive function, emotional well-being, and overall quality of life. Patients with ongoing seizures are at increased risk of hospitalization, status epilepticus, sudden unexpected death in epilepsy (SUDEP), and a higher overall risk of premature mortality compared with the general population. That is why timely evaluation and access to specialized epilepsy care are so important, especially when seizures persist despite treatment with anti-seizure medications.

Recovery looks different for every patient because seizure disorders vary in cause, severity and treatment path. Some patients improve with medication adjustments alone, while others see meaningful progress after surgery or neuromodulation.

Recovery is often measured by fewer seizures, safer daily activity, possible medication reduction and better quality of life. It also includes ongoing follow-up, because epilepsy care often requires close monitoring and adjustments over time.
