Which generalized seizure is typically seen in children and features brief loss of consciousness with staring episodes?

• A. Absence epilepsy
• B. Generalized epilepsy
• C. Myoclonic
• D. Atonic

Answer: (A)

Absence seizures are brief lapses of consciousness that commonly appear in children, presenting as staring spells with minimal or no movement and then a rapid return to normal activity. This pattern—sudden onset and offset, short duration, and intact postictal recovery—is characteristic of a generalized seizure type seen in kids. During the event, subtle signs like eye blinking or lip smacking may occur, and the child typically has no memory of the spell. An EEG during these episodes reveals a 3 Hz spike-and-wave pattern, a classic finding that helps distinguish absence seizures from other generalized or focal events. Hyperventilation can even provoke the typical EEG changes, underscoring the link between this seizure type and childhood-onset generalized epilepsy. Management usually features ethosuximide as a first-line treatment, with valproic acid option if other seizure types are present.
