We will start by simply learning what defines epilepsy. The ILAE and the International Bureau for Epilepsy (IBE) currently define an epileptic seizure as a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain. It is a clinical event with a wide range of possible manifestations. 

Epilepsy is a disease of the brain defined by any of the following conditions:

  • At least two unprovoked (or reflex) seizures occurring more than 24 hours apart.
  • One unprovoked (or reflex) seizure and a probability of further seizures similar to the general recurrence risk (at least 60%) after two unprovoked seizures, occurring over the next 10 years.
  • Diagnosis of an epilepsy syndrome
In 2017 the ILAE updated seizers into 4 classifications, which of the following is correct?
Grand mal, petit mal, tonic-clonic, staring spells
Generalized, focal, combined, unknown
Absence seizures, tonic jerking, epileptic fits, pseudo seizures,
Convulsions, staring spells, non-epileptic, unknown
Correct Answer: 

Our current description of seizures is guided by the 2017 International League Against Epilepsy, (ILAE) revised classification of seizure types. A seizure is first described by type of onset, which includes focal, generalized, or unknown. A seizure of unknown onset may have defining characteristics; however, due to lack of information, it cannot be confidently classified as focal or generalized.
