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.)
Lack of sleep, stress, and fevers may trigger nocturnal seizures. Causes of seizures may be due to natural events such as a congenital defect of the brain or chemical imbalances. There may be unnatural causes such as a traumatic brain injury or brain tumor. Sometimes a cause of the seizures cannot be determined.
