What are Secondarily Generalized Seizures?
Secondarily generalized seizures begin as partial seizures. They start in part of the brain as an aura (a simple partial seizure) or as a change in awareness (a complex partial seizure) before spreading throughout the brain to become a generalized, usually tonic clonic, seizure, tonic clonic seizures] in which consciousness is lost. Secondarily generalized seizures have a focus-one focal point of onset, unlike primarily generalized seizures, which apparently start all over the brain at the same time.
