Epilepsy syndromes are defined either by a specific set of symptoms or by the area of the brain where the seizures originate. Some of the symptoms include types of seizures and age of seizure onset. Other symptoms include the frequency and severity of the seizures and the time of day in which they occur. Epilepsy syndromes are likely to be present at birth or appear during childhood. The treatment for childhood epilepsy syndromes may include medication, diet therapy, nerve stimulation, or surgery.
