seizure types

In March 2017 the International League Against Epilepsy (ILAE), a group of the world's leading epilepsy professionals, introduced a new method to group seizures. This gives doctors a more accurate way to describe a person's seizures, and helps them to prescribe the most appropriate treatments.

Seizures are divided into groups depending on:

  • where they start in the brain (onset)
  • whether or not a person's awareness is affected
  • whether or not seizures involve other symptoms, such as movement

Depending on where they start, seizures are described as being focal onset, generalised onset or unknown onset.
