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.
