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 may be the result of a medical problem. Low blood sugar, infection, a head injury, accidental poisoning, or drug overdose can cause a seizure. A seizure may also be due to a brain tumor or other health problem affecting the brain. In addition, anything that results in a sudden lack of oxygen to the brain can cause a seizure. In some cases, the cause of the seizure is never discovered. When seizures recur, it may indicate the chronic condition known as epilepsy.
