How are seizures classified
Seizures are classified according to their clinical and electroencephalographic (EEG) characteristics. Classification schemes have been proposed in 1981, 1989, and most recently 2010. Terms from each scheme are still commonly in use
Classification of Seizures and Epilepsy
| Year | Seizures (Defined by Onset) | Epilepsy (Defined by Etiology) |
|---|---|---|
| 1981 | Partial (simple vs complex) vs generalized | N/A |
| 1989 | Localization related vs generalized | Symptomatic vs idiopathic vs cryptogenic |
| 2010 | Focal (retained consciousness vs dyscognitive) vs generalized | Structural/metabolic vs genetic vs unknown |
