Epilepsy is a disorder of the brain characterized by repeated seizures. A seizure is usually defined as a sudden alteration of behavior due to a temporary change in the electrical functioning of the brain. Normally, the brain continuously generates tiny electrical impulses in an orderly pattern. Anything that interrupts the normal connections between nerve cells in the brain can cause a seizure; this includes a high fever, low blood sugar, alcohol or drug withdrawal, or a brain concussion.
