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.)
Fever seizures (febrile convulsions) are the most common cause of a single seizure, especially in children. For more information, see the topic Fever Seizures. Epilepsy is a nervous system problem that causes seizures. It can develop at any age. For more information, see the topic Epilepsy. A seizure can be a symptom of another health problem, such as: 1  A rapidly increasing fever (fever seizure). 2  An extremely low blood sugar level in a person who has diabetes.
