What Is Epilepsy?

Epilepsy is a chronic, non-communicable neurologic disorder defined by two or more unprovoked seizures. Provoked seizures result from some immediately recognizable stimulus (for example, low blood sugar in people with diabetes), while unprovoked seizures have no immediately recognizable cause. Provoked seizures are unlikely to recur if the provocations can be avoided; however, unprovoked seizures have the tendency to recur and are the hallmark of epilepsy. When someone has two or more seizures, doctors diagnose epilepsy.
