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.)
Epileptic: These seizures have no apparent trigger (that is, they are unprovoked), and they occur repeatedly. Epileptic seizures are called a seizure disorder or epilepsy. What causes epileptic seizures is often unknown (called idiopathic epilepsy). But they may be caused by various brain disorders, such as structural abnormalities, strokes, or tumors. In such cases, they are called symptomatic epilepsy.
