Burst-suppression on EEG is most commonly seen in which clinical context?

• A. Absence Seizures
• B. Severe Encephalopathy
• C. Peripheral Neuropathy
• D. Normal Awakening

Answer: (B)

Burst-suppression on EEG reflects a state of severe global brain dysfunction, with alternating bursts of activity and long periods of suppression. This pattern is most commonly seen in severe encephalopathy, such as coma from hypoxic-ischemic injury, profound metabolic derangements, or after deep anesthesia or cooling. It indicates extensive cortical and subcortical dysfunction and often carries a poor prognosis. The other options don’t fit: absence seizures produce rhythmic spike-and-wave discharges rather than bursts and suppression; peripheral neuropathy involves the peripheral nerves and typically yields a normal EEG; normal awakening would also show a normal EEG without burst-suppression.
