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.)
1 Other causes include head injury, prenatal injury, and poisoning. 2  Triggers for seizures include lack of sleep, alcohol consumption, stress, or hormonal changes associated with the menstrual cycle.  There are many types of seizures, divided into two major categories: focal seizures and generalized seizures.
