,ANSWER 1 · SOURCE 361
This EEG is best described as:
B. The background is best described as burst-suppression with lateralized (unilateral), highly
epileptiform, identical bursts
CLINICAL RATIONALE
Rationale: The EEG demonstrates recurrent bursts predominantly confined to one hemisphere, alternating with periods of
suppression. Under ACNS terminology, burst-suppression is present when attenuation or suppression occupies 50–99% of the
recording . The bursts are highly epileptiform because most contain multiple spikes or sharp waves occurring at an average rate of at
least 1 Hz, or contain a rhythmic ictal-appearing pattern. They are identical bursts because the initial 0.5 seconds or longer of more
than 90% of the bursts have a visually similar morphology. It is more precise to say “burst-suppression with lateralized bursts” rather
than “unilateral burst-suppression,” because lateralization describes the location of the bursts.
