[Differential traits of non-convulsive status epilepticus]

Non convulsive status epilepticus (NCSE) is defined by prolonged loss of awareness and epileptiform activity on electroencephalogram. There are several types of NCSE depending of the clinical and electroencephalographic manifestations: generalized (typical or atypical absence status, status epilepticus during sleep) and partial (complex partial and simple partial status epilepticus). NCSE diagnosis and treatment should be performed early due to the potential brain damage associated to it, specially in complex partial NCSE. Accurate differential diagnosis from other imitators of NCSE (psychogenic seizures, metabolic encephalopaties or antiepileptic drug intoxication) is necessary for early treatment.
