Epilepsy, sometimes called “seizure disorder,” is a neurological disease that causes
recurring, unprovoked seizures. Every brain has the potential to seize, but a person
with epilepsy has a lower seizure threshold. Seizures are sudden, temporary surges
of abnormal and excessive electrical activity in the brain that change or disrupt the
way messages are sent between brain cells. These electrical surges can cause
involuntary changes in body movement or function, sensation, behavior, or
awareness.
