How is status epilepticus defined in the material?

• A. A single seizure lasting 5 minutes or repeated seizures without return of consciousness
• B. Seizures lasting less than 2 minutes
• C. Seizures that occur only during sleep
• D. Seizures that respond to benzodiazepines

Answer: (A)

Status epilepticus is a state of ongoing or recurrent seizure activity with no meaningful recovery between events, requiring urgent treatment. It is defined clinically as a seizure lasting 5 minutes or longer, or two or more seizures without full recovery of consciousness between them. That description matches the option stating a single seizure lasting 5 minutes or repeated seizures without return of consciousness, making it the best choice. Seizures that end before 5 minutes are not status epilepticus. Seizures that occur only during sleep or seizures that stop after benzodiazepines do not define status epilepticus; the key feature is persistence or uninterrupted recurrence of seizures. In practice, stopping the seizure quickly with appropriate antiseizure therapy is crucial to reduce brain injury and systemic complications.
