People with epilepsy have seizures. During a seizure, the nerve cells in the brain don't communicate normally. The usual electrical activity in the brain becomes altered. These seizures may last a few seconds or a few minutes.
Some people with epilepsy will have or eventually develop refractory epilepsy. This means that medicines don't work well, or at all, to control the seizures.
If you have refractory epilepsy, the type of seizures you have may affect your treatment. Seizures may be:
Refractory epilepsy can have a big effect on your life. People with refractory epilepsy may have trouble at work or school. They may worry a lot about when their next seizure will come. They may also have injuries that result from their seizures. If your health care provider thinks you have refractory epilepsy, he or she may suggest that you visit a medical center that specializes in epilepsy.
Some seizures have known causes, such as head injuries, infections, fevers, or brain tumors or other brain abnormalities, but often the cause of seizures in epilepsy is not known.
In the same way, it is not clear why some people with epilepsy are not helped by antiepilepsy drugs, or why these drugs sometimes stop working. The electrical activity in the brain during a seizure might become so high that drugs are no longer able to control it, but why this happens is not known.
The symptoms of a seizure can include:
If you still have seizures while you're taking an antiepilepsy drug, you may have refractory epilepsy.
Your healthcare provider will likely ask you many questions about your seizures. You will likely also have a test called an electroencephalogram (EEG). This involves placing electrodes on your scalp to measure your brain's activity.
Your healthcare provider may also want you to have a CT or MRI scan of your brain. If you eventually need surgery to treat the problem, your healthcare provider may do more tests like these to find out where your seizures are starting.
You will need to work closely with your healthcare provider to determine whether your epilepsy is refractory. Your provider may need to watch you closely during more seizures to try several drugs before your he or she feels your condition is refractory. Your healthcare provider may want you to check in regularly to report your symptoms as you try different medication dosages.
Your healthcare provider may suggest that you take another antiepilepsy drug, either alone or with others you are already taking. There are many different medicines in this class, some of the medicines that may be tried include (generic names listed):
If medicines aren't helping prevent your seizures, your healthcare provider may suggest other methods:
It might not be possible to prevent all of your seizures, but it is very important to use medicines exactly as your healthcare provider directs. Using your antiepilepsy drugs the right way may help them work better to control your condition.
Living with refractory epilepsy can be difficult. People with refractory epilepsy may worry a lot about when their next seizure will come. They may have trouble at work or school, and they may no longer be allowed to drive. They may also have injuries that result from their seizures. It is important to do what you can to limit your chances of injury.
A special diet called a ketogenic diet may help control your seizures. This type of diet is high in fats and low in carbohydrates. If you follow this diet, you will need to work closely with your healthcare provider and take supplements of certain nutrients as needed.
Be sure to talk with your healthcare providers about when you should call. They will likely advise you to call if you continue to have seizures, if the intensity or frequency of the seizures becomes worse, or if you have new symptoms during or after your seizures.
