There are many types of seizures. Eighty percent of people have Localization-Related Epilepsy (LRE) and 20 percent have Primary Generalized Epilepsy (PGE). The purpose of such a revision is to recognize that some seizure types can have either a focal or generalized onset, to allow classification when the onset is unobserved, to include some missing seizure types, and to adopt more transparent names. Seizure types. Focal seizures can start in one part of the brain and spread to other areas, causing symptoms that are mild or severe, depending on how much of the brain becomes involved. People can also have myoclonic seizures as part of other epilepsy related-conditions. People with Lennox Gastaut syndrome can have a distinctive EEG pattern called slow spike and wave. You’ve most likely heard of grand mal seizures, as they are “the most noticeable” and associated with how we portray… Focal Seizure Types: Seizure Type: Clinical Features: Focal onset seizures with awareness: Consciousness is spared; Symptoms are dependent on the anatomical location of the seizure.
