Epilepsy is a brain disorder in which a person has repeated seizures over time. Seizures are episodes of uncontrolled and abnormal firing of brain cells that may cause changes in attention or behavior. Epilepsy occurs when permanent changes in the brain cause it to be too excitable or irritable. As a result, the brain sends out abnormal signals. This leads to repeated, unpredictable seizures. (A single seizure that does not happen again is not epilepsy.)
Some seizures are considered provoked if they are caused by an event that happened to the individual. Brain injuries are often the cause of provoked seizures. Other examples include: 1  birth trauma. 2  alcohol or drugs. 3  head or brain trauma.
