title: [Electroencephalographic features of nonconvulsive status epilepticus].
abstract: Continuous EEG monitoring (cEEG) has been recently applied in a neurocritical care setting in the US. The purpose of cEEG is primarily to detect nonconvulsive status epilepticus (NCSE) and secondarily, to evaluate the treatment of NCSE. It is difficult to diagnose NCSE in cEEG because of its variability. In the American Clinical Neurophysiology Society's Standardized Critical Care EEG Terminology 2012, EEG localization is placed under major term 1 and is classified as Lateralized (L), Generalized (G), Bilateral Independent (BI), and Multifocal (Mf). Morphology is placed under major term 2 and is classified as periodic, rhythmic, and spike-and-wave. Although there are no unequivocal criteria for the diagnosis of NCSE, the appearance of spatial and temporal changes in the EEG is essential for diagnosis.
