A school nurse is teaching a parent about absence seizures. Which of the following information should the nurse include?

Absence seizures (petit mal) involve sudden brief episodes of staring and unresponsiveness, often with eye blinking or lip smacking. The child appears to "zone out" — easily mistaken for daydreaming or inattention. Absence seizures do not have an aura. They have an abrupt onset (not gradual). They typically last 5–30 seconds (not 30–60 seconds) and the child returns to normal activity immediately without a postictal period.
