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.)
A variety of conditions and substances can trigger seizures. Common causes include congenital abnormalities of the brain, illicit drug use, fever, brain tumors and metabolic imbalances, such as high levels of glucose or sodium. Epilepsy is a condition in which a person experiences repeated seizures, due to an overall electrical disturbance in the brain.
