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

A. "This type of seizure can be mistaken for daydreaming.": Absence seizures are brief, sudden episodes of impaired consciousness, often with staring and subtle motor activity. Because these episodes are very short and the child resumes normal activity immediately, they can easily be misinterpreted as inattentiveness or daydreaming. B. "This type of seizure lasts 30 to 60 seconds.": Absence seizures are typically very brief, usually lasting 5 to 10 seconds, rarely up to 15 seconds. A duration of 30 to 60 seconds is longer than expected and more characteristic of other seizure types. C. "The child usually has an aura prior to onset.": Absence seizures do not usually have a preceding aura. Auras are more commonly associated with focal or partial seizures, not generalized absence seizures. D. "This type of seizure has a gradual onset.": Absence seizures have a sudden onset and end abruptly. There is no gradual buildup of symptoms, which helps differentiate them from other neurological or behavioral events.
