Early recognition and treatment of non convulsive status epilepticus are essential to optimize response to treatment and to prevent neurological sequelae, over diagnosis and aggressive use of anticonvulsants can contribute to morbidity and mortality.It displays great diversity in response to anticonvulsants,therefore treatment in intensive care units is required for selected cases .The aetiology and clinical forms are strong predictors for the overall prognosis.Treatment is poorly understood and follows the standard regimen for convulsive status epilepticus
