Dialeptic seizure

What it means

A dialeptic seizure is a type of seizure characterized predominantly by reduced responsiveness or awareness and with subsequent at least partial amnesia of the event.

The main ictal manifestation of dialeptic seizures is an alteration of consciousness rather than motor or sensory features. The term describes the pure clinical semiology of a seizure and is used independently of the ictal electrographic findings: it could describe a seizure of focal, generalized or unknown onset. In 2017 the ILAE Commission for Classification and Terminology recommended classifying a seizure as having focal or generalized onset only when there is a high degree of confidence (>80%, arbitrarily chosen to parallel the usual allowable beta error) in the accuracy of this determination.
