Non-convulsive status epilepticus (NCSE) may follow a number of precipitating factors. Identifying the cause is important for developing an effective treatment plan and for predicting prognosis.


Factors that may precipitate non-convulsive status epilepticus:

(1) acute intracranial event (stroke, head trauma, etc)

(2) drug intoxication

(3) drug or alcohol withdrawal (especially benzodiazepines)

(4) history of epilepsy with nonadherence for antiepileptic medication

(5) brain tumor

(6) brain surgery

(7) dementia

(8) meningitis or other CNS infection

(9) electrolyte abnormality (hypocalcemia, hyponatremia)

(10) remote intracranial injury (previous stroke, etc)
