Over 40 Different Types Of Seizures - Revised
Sun, 03/25/2007 - 03:04It has been said repeatedly that there are over 40 different types of seizures with more or less only the most 'popular' listed. Let's see if we can locate the ones that aren't. These types of seizures affect someone and I feel need to be noted. I'm curious to see how many can be located. Anyone interested in helping me find them, please list what you find here along with their description. Thank you! Take care and have a good day! -Spiz This thread is a revision of the first one in order to make changes and additions.
A Note from epilepsy.com's Editors (August 2017)
This forum post was originally created in 2007. Over the years, many of the links provided in the comments have expired or may not have been updated. To find reliable, expert-verified information, visit the following sections of this site:
In late 2016, the International League Against Epilepsy (ILAE) approved a new way of organizing seizures that reflects recent advances in our understanding of the brain and seizures. This new system will make diagnosis and classification of seizures easier and more accurate. Learn more here.
These terms don’t change what occurs during a seizure, but offer a different way of naming seizures. More accurate ways of naming seizures can lead to more appropriate treatment.
We also want to take this opportunity to remind site visitors...
- If your seizures are not controlled, seek out the help of an epilepsy specialist or visit an epilepsy center to explore treatment options that may include medications, surgery, devices, and dietary therapy. Newer approaches and research trials are also available at many centers.

EEG Atlas: Localization-related Epilepsies :The International Classification of Epileptic Syndromes and Epilepsies (International League Against Epilepsy [ILAE], 1989) classifies the epilepsies along 2 dichotomies: partial (ie, localization-related) versus generalized, and idiopathic versus cryptogenic or symptomatic. This double dichotomy conveniently allows presentation of the epilepsy classification in a simple table, as follows... EEG Atlas: Generalized Epilepsies : The International Classification of Epileptic Syndromes and Epilepsies (International League Against Epilepsy [ILAE], 1989) classifies the epilepsies along 2 dichotomies: partial (ie, localization-related) versus generalized, and idiopathic versus cryptogenic or symptomatic. This double dichotomy conveniently allows the epilepsy classification system to be presented in a simple table, as follows... Pyridoxine-Dependant Seizures (PDS) :Although rare, pyridoxine-dependent seizure (PDS) is a recognized cause of intractable seizures in neonates, psychomotor developmental delay, and, sometimes, death in untreated patients (Gupta, 2001; Baxter, 2001; Yoshikawa, 1999). Hunt et al first described PDS in 1954 (Gupta, 2001; Burd, 2000). Since then, fewer than 100 cases have been reported worldwide (Gupta, 2001; Yoshikawa, 1999). Later onset seizures due to pyridoxine deficiency have been reported (Gupta, 2001; Grillo, 2001). The 2 types of presentations are classic and atypical. The classic presentation consists of intractable seizures that appear within hours of birth and are resistant to conventional anticonvulsants. The seizures respond rapidly to administration of parenteral pyridoxine (Gupta, 2001). A trial of pyridoxine is recommended in all seizures that have no clear etiology and occur before the child is aged 18 months (Grillo, 2001)... Epileptic and Epileptiform Encephalopathies :Recently, the ILAE Task Force on Classification and Terminology (Engel, 2001) proposed a modified diagnostic scheme for epileptic seizures and epilepsy that for the first time recognizes a distinct category for epileptic encephalopathies in which the epileptiform abnormalities may contribute to progressive dysfunction. This category includes the following: early myoclonic encephalopathy, Ohtahara syndrome, West syndrome, Dravet syndrome, myoclonic status in nonprogressive encephalopathies, Lennox-Gastaut syndrome, Landau-Kleffner syndrome, and epilepsy with continuous spikes during slow wave sleep (CSWS)...
