What is Epilepsy?
Epilepsy is a brain disorder in which clusters of nerve cells, or neurons, in the brain sometimes signal abnormally. In epilepsy,
the normal pattern of neuronal activity becomes disturbed, causing strange sensations, emotions, and behavior or sometimes
convulsions, muscle spasms, and loss of consciousness. Epilepsy is a disorder with many possible causes. Anything that disturbs
the normal pattern of neuron activity - from illness to brain damage to abnormal brain development - can lead to seizures.
Epilepsy may develop because of an abnormality in brain wiring, an imbalance of nerve signaling chemicals called neurotransmitters,
or some combination of these factors. Having a seizure does not necessarily mean that a person has epilepsy. Only when a person
has had two or more seizures is he or she considered to have epilepsy. EEGs and brain scans are common diagnostic test for
epilepsy.
Is there any treatment? Once epilepsy is diagnosed, it is important to begin treatment as soon as possible. For about 80 percent of those diagnosed
with epilepsy, seizures can be controlled with modern medicines and surgical techniques. Some antiepiletic drugs can interfere
with the effectiveness of oral contraceptives. In 1997, the FDA approved the vagus nerve stimulator for use in people with
seizures that are not well-controlled by medication.
What is the prognosis? Most people with epilepsy lead outwardly normal lives. While epilepsy cannot currently be cured, for some people it does eventually
go away. Most seizures do not cause brain damage. It is not uncommon for people with epilepsy, especially children, to develop
behavioral and emotional problems, sometimes the consequence of embarrassment and frustration or bullying, teasing, or avoidance
in school and other social setting. For many people with epilepsy, the risk of seizures restricts their independence (some
states refuse drivers licenses to people with epilepsy) and recreational activities. People with epilepsy are at special risk
for two life-threatening conditions: status epilepticus and sudden unexplained death. Most women with epilepsy can become
pregnant, but they should discuss their epilepsy and the medications they are taking with their doctors. Women with epilepsy
have a 90 percent or better chance of having a normal, healthy baby.
What research is being done? Scientists are studying potential antiepileptic drugs with goal of enhancing treatment for epilepsy. Scientists continue to
study how neurotransmitters interact with brain cells to control nerve firing and how non-neuronal cells in the brain contribute
to seizures. One of the most-studied neurotransmitters is GABA, or gamma-aminobutyric acid. Researchers are working to identify
genes that may influence epilepsy. This information may allow doctors to prevent epilepsy or to predict which treatments will
be most beneficial. Doctors are now experimenting with several new types of therapies for epilepsy, including transplanting
fetal pig neurons into the brains of patients to learn whether cell transplants can help control seizures, transplanting stem
cells, and using a device that could predict seizures up to 3 minutes before they begin. Researchers are continually improving
MRI and other brain scans. Studies have show that in some case, children may experience fewer seizures if they maintain a
strict diet - called the ketogenic diet - rich in fats and low in carbohydrates.
