The brain communicates with other parts of the body through electrical impulses. For the brain to function properly, these electrical impulses must be discharged in an orderly, organized, and coordinated way. If not, seizures may occur. In seizure disorders, the brain's electrical activity is occasionally disturbed, resulting in temporary brain dysfunction. There are two basic types of seizure disorders, epileptic seizures and nonepileptic seizures.
