Which seizure type is defined by a brief lapse of attention?

• A. Generalized
• B. Absence
• C. Complex Partial
• D. Simple Partial

Answer: (B)

A brief lapse of attention points to absence seizures. Absence seizures are generalized, nonconvulsive events where consciousness is momentarily impaired, causing a brief staring spell or unresponsiveness that usually lasts only a few seconds. The person resumes normal activity immediately afterward and often has no memory of the episode. This differs from simple partial seizures, where awareness remains intact, and from complex partial seizures, where consciousness is impaired along with repetitive, automatic behaviors. Absence seizures are most common in children and are often characterized on EEG by a distinctive 3 Hz spike-and-wave pattern.
