How is status epilepticus defined?

• A. A seizure lasting more than 5 minutes or two or more seizures without full recovery between them
• B. Any seizure lasting under 1 minute
• C. A single seizure with complete recovery within 30 seconds
• D. Two seizures within a minute with full recovery in between

Answer: (A)

Status epilepticus is prolonged or rapidly recurring seizure activity in which the person does not return to their baseline level of consciousness between events. The practical definition used in many clinical settings is a seizure lasting more than five minutes, or two or more seizures occurring without full recovery of consciousness between them. The five-minute threshold matters because neuronal injury and complications become more likely the longer the seizure persists, so urgent treatment is warranted to stop it and support the patient.

Brief episodes under five minutes that resolve with full recovery between them do not meet this definition, and a single short seizure that ends quickly likewise does not. Two seizures happening within a short time but with full recovery between them would not satisfy the criterion of “no full recovery between seizures,” so they wouldn’t be considered status epilepticus.
