Episodic Low Amplitude Events.
In a series of 27 electroencephalograms from 22 patients, well-defined brief attenuations occurred interspersed among the background activity. These “episodic low amplitude events” (ELAEs) typically lasted 0.5–4 seconds. They were hemispheric or bisynchronous and occurred in patients with coma of various etiologies, including status epilepticus. The episodes of attenuation were brief and no bursts of activity were present, distinguishing this finding from burst-suppression. In the patients with coma other than status epilepticus, prognosis was poor. In the setting of status epilepticus, the prognosis depended on the etiology of status. ELAEs are a manifestation of seriously abnormal electroencephalographic activity and correlate with α 45% mortality.
