I found a little info yesterday that might help a little bit..
What is the difference between seizures and epilepsy?
Seizures are a symptom of epilepsy. They occur when a group of brain cells — which normally discharge in a chaotic or random manner — suddenly discharge together in rhythmic bursts. Epilepsy describes a state in which a group of abnormal brain cells, scar tissue, malformation, or other underlying condition makes the brain susceptible to periodic or recurring rhythmic bursts of electrical energy.
