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.)
There can be number of reasons why someone has a seizure. In fact, anything that disturbs the normal pattern of nerve cell activity in the brain -- from illness to abnormal brain development -- can cause seizures. Some possible causes of seizures may include: 1  Fever. 2  Chemical imbalance. 3  Medical conditions. 4  Trauma. 5  Developmental problems. 6  Poisoning.
