About Epilepsy

Epilepsy is a disorder of the brain that causes seizures. These seizures are not caused by a temporary underlying medical condition such as a high fever.

Epilepsy can affect people in very different ways. This is because there are many causes and many different kinds of seizures. Some people may have multiple types of seizures or other medical conditions in addition to epilepsy. These factors play a major role in determining both the severity of the person’s condition and the impact it has on his or her life.
