Definition

Noun: A brief, sudden episode characterized by a temporary loss or impairment of consciousness. The person experiencing it typically has no memory of the event afterward. It may be accompanied by subtle physical signs, such as slight twitching or fluttering eyelids. This type of event is a common manifestation of a form of epilepsy known as petit mal.

It is used by doctors, nurses, and in patient education materials. - It functions as a countable noun (e.g., an absence seizure, multiple absence seizures). - It is often modified by adjectives describing frequency or severity (e.g., frequent absence seizures, a typical absence seizure).
