Seizure

Treat a seizure lasting at least 5 minutes, or recurrent clinical or electrographic seizures without return to baseline, as status epilepticus rather than waiting for spontaneous resolution. This threshold applies to generalized convulsive and electrographic seizure activity and should trigger immediate emergency management.

For convulsive status epilepticus, prioritize airway protection, oxygenation, cardiorespiratory monitoring, IV access, bedside glucose measurement, and prompt benzodiazepine treatment. Benzodiazepines can cause decreased respirations, oversedation, and cardiopulmonary instability; anticipate ventilatory support when consciousness remains depressed or repeated rescue dosing is required. publications aappublications aapRescue Medicine for Epilepsy in Education Settings

Escalate to ICU-level care for persistent convulsions, inability to protect the airway, or seizures that continue after initial therapy. Refractory status epilepticus is ongoing seizure activity despite one benzodiazepine and one non-benzodiazepine antiseizure medication; it requires critical care and IV anesthetic therapy to suppress seizures.

Obtain a focused history and examination after stabilization, then decide whether the event was provoked by a metabolic, toxic, infectious, structural, or medication-related insult or was unprovoked. Initial laboratory evaluation typically includes electrolytes; add targeted studies according to clinical context rather than using an indiscriminate panel.

Use fever, immunosuppression, meningismus, persistent encephalopathy, or other features concerning for CNS infection to lower the threshold for lumbar puncture. In pregnancy, evaluate alternative causes of seizure with history, examination, medication and substance review, medical comorbidity assessment, and clinically directed CBC, glucose, electrolytes, urinalysis for protein, toxicology studies, lumbar puncture, and brain imaging.

Do not anchor on epilepsy when the event history favors a mimic. Convulsive syncope, convulsive concussion, movement disorders, rigors, sleep-related events, and psychogenic nonepileptic spells remain in the differential; a witness account of onset, motor sequence, awareness, and recovery is often the decisive data source.

Order EEG urgently for persistent altered mental status, unexplained behavioral change, or coma after a suspected seizure because nonconvulsive status epilepticus depends on EEG findings and may not have a prominent motor component. Delayed recognition is clinically consequential: approximately half of patients with nonconvulsive status epilepticus are diagnosed more than 24 hours after emergency department arrival.

After a first unprovoked seizure, EEG findings help recurrence-risk counseling. Interictal epileptiform discharges are associated with increased recurrence risk after a first unprovoked seizure, whereas nonspecific EEG abnormalities should not be treated as equivalent evidence of epilepsy.

Use CT or MRI selectively to investigate a suspected structural cause, particularly when the history or examination raises concern for stroke, trauma, tumor, infection, or another intracranial disorder. In pregnant patients with seizure, CT or MRI is part of the evaluation for alternative diagnoses. ajogajogEclampsia in the 21st century

Adults with a first unprovoked seizure should be counseled that recurrence risk is greatest in the first 2 years and is estimated at 21% to 45%. This estimate supports structured follow-up and a shared decision about whether immediate long-term antiseizure treatment offers sufficient benefit relative to treatment burden.

One unprovoked or reflex seizure can establish epilepsy when the estimated probability of recurrence is at least 60% over the next 10 years. Apply this threshold only after excluding an acute provoking cause and integrating EEG, imaging, clinical history, and other evidence of an enduring predisposition to recurrent seizures.

Avoid abruptly discontinuing an established antiseizure medication because abrupt withdrawal can increase seizure frequency and precipitate status epilepticus.

When seizures persist despite a benzodiazepine and one non-benzodiazepine antiseizure medication, manage as refractory status epilepticus in critical care with IV anesthetic therapy. Continue evaluation for a reversible cause while seizure suppression is being established; refractory status management does not replace metabolic, infectious, toxicologic, or structural evaluation.

For established epilepsy with prolonged convulsions, use the patient’s individualized emergency management plan when immediately available. A convulsive seizure lasting 5 minutes or longer, or exceeding the individual’s usual duration by more than 2 minutes, is a medical emergency requiring rescue treatment pathways.

In pregnancy, seizure evaluation must remain broad even when eclampsia is suspected. Medication exposure, substance use, comorbid illness, CNS infection, stroke, and other intracranial pathology can alter both the diagnostic workup and definitive treatment. ajogajogEclampsia in the 21st century
