Epilepsy affects about 1% of the population, and, in about 30% of patients with epilepsy, seizures cannot be controlled with medications.
- There are about as many patients with uncontrolled seizures as there are patients with multiple sclerosis.
- The majority of patients with seizures can be managed by neurologists, but the 30% or so that are difficult to control and do not respond to standard treatment require the next level of care at an epilepsy center.
What is done at an epilepsy center?
- An evaluation at a specialized center typically begins with Video EEG monitoring to record the seizures. This testing can confirm the diagnosis of epilepsy, the type of epilepsy, and where the seizures start in the brain. Answers to these questions help give people a more accurate outlook of what they can expect, understand what medications may work best for them, and consider which non-drug treatments may be appropriate.
- Many other tests may be done to look for causes of the epilepsy, the impact on a person’s health, cognition or thinking, and their general health.
- How living with epilepsy affects an individual’s and their family’s quality of life is also critical to understand.
What can people learn from an evaluation at an epilepsy center?
In general, if a person has uncontrolled epilepsy, an evaluation at a specialized center can determine the following:
- The diagnosis of epilepsy was incorrect.
- The diagnosis of epilepsy was correct but the medication regimen was not the best for the individual. This could mean that the wrong medication was used or the dose was wrong for that person.
- The patient has medically intractable epilepsy and medications will not work. In this case, options other than medications should be considered.
- The most effective non-drug treatment is, by far, resective surgery; that is removing the area of cortex that is generating the seizures if it can be identified. Most often this area is in the temporal lobe.
- Other options include the ketogenic diet, neurostimulation, vagus nerve stimulation and other types of surgery.
Are there different types of epilepsy care?
- Video EEG monitoring is the key to proper epilepsy management at an epilepsy center. Yet there can be many differences in how this test is done and interpreted. The specialist's experience in EEG monitoring is important to consider. In other words, it takes more than an EEG machine and a video camera to perform EEG-video monitoring.
- The National Association of Epilepsy Centers (NAEC) has defined various levels of Epilepsy Centers. To be called “comprehensive”, a center should provide all approved treatment options for seizures, including all available medications and the non-drug treatments. A comprehensive center should be … well … comprehensive.
Why should people consider going to an epilepsy center?
- Don’t settle for continued seizures! Unfortunately, despite several official recommendations, some neurologists and patients tend to become complacent and tolerate seizures as if there were no options beyond basic medications. All too often, it seems, treatment only consists of refilling medications.
- Some people have types of epilepsy that can never be well-controlled. Yet many others can get seizures much better controlled if they consider newer or different treatments.
- Make sure your diagnosis is correct! Many people are treated for years without every having EEG monitoring to be sure they have epilepsy or learn what other treatments may be possible.
- For example, about 30% of patients sent to specialized centers for difficult seizures turn out to not have seizures and to have been misdiagnosed. On average, it takes these patients 7-10 years before obtaining the correct diagnosis. This usually means many years of antiepileptic medications, ER visits, hospitalizations, tests, procedures, and other treatments for a wrong diagnosis of seizures.
- Similarly, patients who become seizure free after successful surgery for epilepsy have, on average, waited 15 years to be referred to a specialized center.
How can people get to the right type of care earlier?
- Despite guidelines published by the American Academy of Neurology to encourage early referrals, recent evidence suggests that this tragic delay has not changed in the last 10 years.
- The National Association of Epilepsy Centers has also published guidelines for referrals, however, the information has to get out to the primary care and neurology communities, as well as to the general public. People need to know where they can get the ‘right help at the right time’.
- To help improve this situation, the ILAE recently published a consensus definition of “refractory” epilepsy and the American Academy of Neurology included "surgical therapy referral consideration" in a series of quality measures. Hopefully helping people understand what refractory epilepsy is and what to do if one has this may help. There is still much work to be done!
