Q

How to classify epilepsy?

A

Use a multi-level framework. ILAE classification at 4 levels

  1. Seizure type

> Generalised onset - eg tonic-clonic, tonic, myoclonic, absence = both parts of the prain

> Focal onset – aware and impaired awareness and progressive = one part of the brain

> Unknown

> Unclassified

  1. Epilepsy type

> Generalised

> Focal

> Generalised and focal (eg Dravet and Lenox-Gastaut)

> Unknown (eg epilpetic spasms)

  1. Epilpesy syndrome

> Distinct clinical entity e.g. West syndrome, Dravet syndrome, Lennox-Gastaut syndrome

  1. Epilepsy with etiology

> Genetic, structural, metabolic, immune, infectious, unknown
