Status epilepticus is a medical emergency — a seizure lasting >5 minutes or repeated seizures without recovery between. It's the most severe form of seizure and requires immediate medical treatment. Without treatment, status epilepticus can cause brain damage and death.
What is status epilepticus
Definition: seizure lasting >5 minutes OR repeated seizures without recovery between. Most common type: generalized tonic-clonic status — convulsive status. Other types: absence status, focal status — less common. Prevalence: affects ~40 per 100,000 people annually — medical emergency. Mortality: 10–20% mortality rate — serious condition. Brain damage: prolonged seizures cause neuronal damage — time-critical.
Causes of status epilepticus
Epilepsy: breakthrough seizures in known epilepsy — medication non-adherence, illness. Acute symptomatic: stroke, brain injury, infection, metabolic — provoked seizures. Medication withdrawal: stopping antiseizure medications abruptly — provoked. Alcohol withdrawal: alcohol withdrawal seizures — provoked. Fever: febrile status in children — provoked. Unknown: no clear cause — cryptogenic status.
Recognizing status epilepticus
Prolonged seizure: single seizure lasting >5 minutes — status. Repeated seizures: multiple seizures without recovery — status. No recovery: person doesn't return to baseline between seizures — status. Convulsive: generalized tonic-clonic — most dangerous type. Non-convulsive: absence or focal — subtler, harder to recognize. Time: every minute counts — call emergency immediately.
Treatment of status epilepticus
Emergency response: call emergency services immediately — time-critical. ABCs: airway, breathing, circulation — basic life support. Benzodiazepines: lorazepam, diazepam — first-line treatment. Antiseizure medications: fosphenytoin, levetiracetam, valproate — second-line. Refractory: doesn't respond to initial treatment — ICU care. Continuous EEG: monitor for non-convulsive status — ICU. Treat underlying cause: infection, metabolic, stroke — essential.
When status epilepticus needs emergency care
If you or someone else has a seizure lasting >5 minutes, repeated seizures without recovery, or seizures not responding to treatment — call emergency immediately. Status epilepticus is life-threatening.

Not necessarily; a single unprovoked seizure needs careful assessment before a diagnosis of epilepsy is made.
No; seizures vary widely. Some involve jerking (generalized or focal), while others present as staring spells, automatisms, or behavioral change with no apparent movement.
Not necessarily. A single unprovoked seizure needs full assessment before diagnosing epilepsy. Provoked seizures have different implications.
Protect from injury, do not put objects in mouth, time the event, turn recovery position after jerking, call emergency if >5 minutes or injury.
Keep the person safe: ease them to the ground, turn onto side, clear nearby objects, do not put anything in mouth, time the event. If seizure lasts over 5 minutes, repeats without recovery, or breathing is impaired, call emergency. Afterward, arrange neurology evaluation with witness/video history for Dr. Jitendra.
