Status epilepticus is a life-threatening condition in which a person has a prolonged seizure or one seizure after another without regaining consciousness in between them. Status epilepticus is more common among people with epilepsy, but about one-third of the people who develop the condition have never had a seizure before. The risks of status epilepticus increase the longer the seizure goes on, which is why you should always get emergency medical help if a seizure lasts more than five minutes.
