AB  - BACKGROUND: Continuous electroencephalogram (CEEG) monitoring is increasingly 
      being used for brain monitoring in neurocritical care setting. This is because of 
      the proven effectiveness of CEEG in diagnosing nonconvulsive status epilepticus 
      (NCSE) as a cause of unexplained consciousness disorder. CEEG has been 
      demonstrated to be effective in determining the response to, and outcome of, NCSE 
      treatment. MAIN BODY: In this review article, the authors described the 
      indication and methods of CEEG and diagnosis based on EEG pattern. As a condition 
      characterized by unexplained consciousness disorder, NCSE is frequently 
      encountered in the neurocritical care setting and is only accompanied by an 
      altered EEG change without any clinically apparent manifestation, such as 
      convulsion. Thus, it is considered a form of status epilepticus manifesting 
      mainly with consciousness disorder. This is a diagnostic challenge but should not 
      be overlooked as NCSE is a curable condition. However, CEEG is required for the 
      correct diagnosis of NCSE, which is difficult to perform in daily clinical 
      practice. There also are several challenges regarding urgent EEG monitoring in 
      the intensive care unit setting, including system-related problems, such as the 
      preparation of mobile EEG devices and collodion-applied electrodes; human 
      resource-related problems, such as staffing of EEG technicians and physicians who 
      can respond flexibly to unscheduled needs; and EEG-specific difficulties in 
      interpretation/diagnosis. These issues preclude the wide spread of CEEG in daily 
      practice. CONCLUSION: Recently, importance of CEEG was well accepted; however, no 
      definitive diagnostic criteria exist for identifying EEG patterns suggestive of 
      NCSE, especially the ambiguous significance of periodic discharges (PDs) further 
      complicates the diagnosis of NCSE. Thus, analyzing the change in EEG patterns 
      over time is important for the correct diagnosis of NCSE. Further studies are 
      needed to collect sufficient CEEG data and assess the outcome of patients who 
      have undergone therapeutic interventions.
