absence seizure


Definition: a seizure characterized by impaired awareness of interaction with, or memory of, ongoing events external or internal to the person; may comprise the following elements: mental confusion, diminished awareness of environment, inability to respond to internal or external stimuli, and amnesia. (The term absence was first used by Louis-Florentin Calmeil [1798–1895] to introduce the concept of epileptic absence for the brief loss of consciousness or confusion seen in epileptic patients.)
