Glossary of Medical Terms
Epilepsy is a nervous system disorder that produces intense, abnormal electrical activity in the brain, which can cause seizures. Epilepsy may result from brain damage, a tumor, or an infection, but in most cases, the cause is unknown.
Some people outgrow the condition and no longer have seizures; others are able to control their seizures with medications. Surgery is sometimes considered for people who have seizures that cannot be well controlled with medication.
