Which description best describes absence seizures in children?

• A. Sudden loss of consciousness with stiff tonic posturing
• B. Brief episodes of staring and unresponsiveness with intact responsiveness between episodes
• C. Repetitive focal motor movements of a limb
• D. Prolonged awake state with confusion

Answer: (B)

Absence seizures in children are nonconvulsive events that cause brief lapses of consciousness. During the spell the child stares and becomes unresponsive for only a few seconds, but between episodes their awareness returns and they interact normally. This rapid, complete return to baseline with no postictal confusion is what sets absence seizures apart from other seizure types. EEG often shows a characteristic 3 Hz spike-and-wave pattern during these spells, which helps confirm the diagnosis. This description fits absence seizures better than a sudden loss of consciousness with stiff posturing (tonic activity), repetitive focal motor movements of a limb (focal seizures), or a prolonged awake state with confusion (postictal or status phenomena).
