Which description matches an absence seizure?

Which description matches an absence seizure?

• A. Staring into space with little to no body movement
• B. Loss of consciousness with convulsions
• C. Aura preceding the event
• D. Repetitive lip-smacking movements

Answer: (A)

Absence seizures are brief losses of awareness with minimal motor activity. The description of staring into space with little to no body movement fits this pattern perfectly: the person seems to "space out" for a few seconds, remains upright, and then quickly returns to normal without confusion afterward. EEG often shows a 3 Hz spike-and-wave pattern during these events, supporting the diagnosis. Other descriptions point to different seizure types. Loss of consciousness with convulsions describes generalized tonic-clonic seizures, which involve dramatic motor activity. An aura is a warning sensation some focal seizures have before onset. Repetitive lip-smacking movements are automatisms seen with certain temporal lobe (focal) seizures and may occur with impaired awareness, but they are not the hallmark of absence seizures.
