 Generalized epilepsy is "primary" because the epilepsy is the originally diagnosed condition itself, as opposed to "secondary" epilepsy, which occurs as a symptom of a diagnosed condition.Generalized seizures can be either absence seizures, myoclonic seizures, clonic seizures, tonic-clonic seizures or atonic seizures.Generalized seizures occur in various seizure syndromes, including myoclonic epilepsy, familial neonatal convulsions, childhood absence epilepsy, absence epilepsy, infantile spasms (West's syndrome), Juvenile Myoclonic Epilepsy, Lennox-Gastaut syndrome and Generalized epilepsy with occipital semiology.
