Here are some frequently asked questions and answers on epilepsy.
Question: What is epilepsy?

The word "epilepsy" comes from the Greek word for "seizure". It is not a disease! Epilepsy is actually an umbrella term covering about twenty different types of seizure disorders.
Question: What are seizures?
Answer: In someone with epilepsy, the normal electrical functions of the brain are interrupted by intermittent bursts of electrical energy that are much more intense than usual.

Question: Can anyone have epilepsy?
