There are many types of seizure disorders that can affect people of all ages. Some of these include epilepsy and non-epileptic seizure disorders. Lennox-Gastaut syndrome is another type of seizure disorder. Infantile spasms produce seizures in babies.

Non epileptic seizure disorders are typically classified by the convulsions created by various medical disorders. Infections, especially in children, may cause this type of seizure. High fevers can also produce seizure disorders in some young individuals. Also known as a febrile seizure, this is not a condition that will last throughout a child's life, as it is a direct result of a high fever.
