Engel classification. To classify postoperative outcomes for epilepsy surgery, Jerome Engel proposed the following scheme, [1] the Engel Epilepsy Surgery Outcome Scale, which has become the de facto standard when reporting results in the medical literature: [2] Class I: Free of disabling seizures. Class II: Rare disabling seizures ("almost ...
Racine stages are a categorization of rodent epileptic seizures proposed by Ronald J. Racine in 1972. Prior to Racine's research in animal epilepsy models, a quantifiable means to describe seizure intensities and their causes was not readily available. Racine's work allowed for studies among different laboratories to be compared and understood ...
Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [10] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [1] The occurrence of two or more unprovoked seizures defines epilepsy. [11]
Syndromes are characterized into 4 groups based on epilepsy type: [1] a. Generalized onset epilepsy syndromes. These epilepsy syndromes have only generalized-onset seizures and include both the idiopathic generalized epilepsies (specifically childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy and epilepsy with generalized tonic- clonic seizures alone), as well as ...
A generalized tonic–clonic seizure, commonly known as a grand mal seizure or GTCS, [1] is a type of generalized seizure that produces bilateral, convulsive tonic and clonic muscle contractions. Tonic–clonic seizures are the seizure type most commonly associated with epilepsy and seizures in general and the most common seizure associated ...
In the field of neurology, seizure types are categories of seizures defined by seizure behavior, symptoms, and diagnostic tests.The International League Against Epilepsy (ILAE) 2017 classification of seizures is the internationally recognized standard for identifying seizure types. [1]
Epilepsy is a neurological condition of recurrent episodes of unprovoked epileptic seizures. A seizure is an abnormal neuronal brain activity that can cause intellectual, emotional, and social consequences. Epilepsy affects children and adults of all ages and races, and is one of the most common neurological disorders of the nervous system. [1]
Strokes, brain bleeds, and traumatic brain injury can all also lead to epilepsy if seizures re-occur. If the first seizure occurs more than 7 days following a stroke, there is a higher chance of the person developing epilepsy. [28] Post-stroke epilepsy accounts for 30%-50% of new epilepsy cases. [28]
